ABOUT THE CHESAPEAKE BAY
The Chesapeake Bay is an estuary, a body of water where fresh and salt water mix. It is the largest estuary in the United States and the third
largest in the world. The Bay is about 200 miles long, stretching from Havre de Grace, Maryland, to Virginia Beach, Virginia. The Bay's
width ranges from 3.4 miles near Aberdeen, Maryland, to 35 miles near the mouth of the Potomac River. The Bay holds more than
15 trillion gallons of water. The Bay is surprisingly shallow. Its average depth, including all tidal tributaries, is about 21 feet. A person
who is six feet tall could wade through more than 700,000 acres of the Bay and never get his or her hat wet. A few deep troughs running along
much of the Bay's length reach up to 174 feet in depth. These troughs are remnants of the ancient Susquehanna River. The Bay and its tidal
tributaries have 11,684 miles of shoreline - more than the entire U.S. West Coast. The surface area of the Bay and its tidal tributaries is
125 billion square feet, or around 4,480 square miles. The Bay supports more than 3,600 species of plants, fish and other animals,
including 348 species of finfish, 173 species of shellfish and more than 2,700 plant species. The Chesapeake is ho me to 29 species of waterfowl and is
a major resting ground along the Atlantic Flyway. Every year, about 1 million waterfowl winter in the Bay region. The Bay produces about
500 million pounds of seafood per year.
-------
About half the water in the Chesapeake Bay is from the Atlantic Ocean. The rest drains into the Bay from an enormous 64,000-square-mile
watershed. The Chesapeake Bay watershed includes parts of six states- Delaware, Maryland, New York, Pennsylvania, Virginia and West
Virginia-and the entire District of Columbia. The Chesapeake's land-to-water ratio is 14:1, the highest of any coastal water body in the world.
The Bay watershed is home to almost 17 million people. About 150,000 people move to the area each year. Experts predict that the population
will increase to nearly 20 million by 2030. Everyone in the watershed lives just a few minutes from one of the 100,000 streams and rivers
that drain into the Bay. Each of these waterways is a pipeline from communities to the Bay. Of the 50 largest tributaries that flow into the Bay,
just three deliver about 80 percent of Bay's fresh water: the Susquehanna River (48 percent), the Potomac River (19 percent) and the James
River (14 percent). During the 1600s, 95 percent of the watershed was forested. Now about 58 percent is forest. The rest of the land has been
developed for other uses, such as agriculture and urban and suburban lands.

At the Chesapeake Bay Program, we are fortunate to have the talented people and the remarkable science
to provide an intimate look at our nation's largest estuary. This assessment's rich reporting on ecosystem
conditions and restoration actions reveals where we are and, more important, how far we have to go.
While there are many individual success stories behind the collective numbers - work that in most cases
will take time to influence water quality - the sobering data in this report mostly reflect only marginal shifts
from last year's results. This affirms the need to take bolder actions and involve a wider network to achieve
sharp improvements in our Bay Barometer readings.
We all are understandably impatient for more rapid progress.
Among the steps being taken by the program, its partners and its Executive Council are:
Setting tough pollution caps throughout the watershed with accompanying action plans
* Reorganizing the program to make it more strategic, effective and accountable for meeting its goals
Continuing partner initiatives as "champions" for innovation and implementation
Setting two-year milestones to better gauge and motivate progress toward an overall deadline
* Enlisting an external evaluator to critically assess program operations and improve efficency
And that's just a start. From the White House to statehouses to town halls, commitments are being made
to take strong actions to stem pollution impacting the Chesapeake Bay and its tributaries.
We all have a role in restoring the beauty and bounty of this treasured resource. This report features a new
chapter that shows how we can all help. Together, we can and will speed the day when the wonders of the
Bay are fully enjoyed by this and future generations.

EXECUTIVE SUMMARY
The Chesapeake Bay is one of the most extraordinary places in America. The unique estuary and
its 64,000-square-mile watershed have tremendous ecological, historic, cultural, economic and
recreational value to the region and the entire country.
For more than 25 years, the partners of the Chesapeake Bay Program have worked to protect and
restore the Bay and its watershed. Goals are set for the health of the Bay and the restoration
measures needed to return the ecosystem to a healthy state. Bay Barometer: A Health and
Restoration Assessment of the Chesapeake Bay and Watershed in 2008 is the annual review
of the partnership's progress.
The Chesapeake Bay and its tributaries are unhealthy primarily because of pollution from excess
nitrogen, phosphorus and sediment entering the water. The main sources of these pollutants are
agriculture, urban and suburban runoff, wastewater, and airborne contaminants.
Despite small successes in certain parts of the ecosystem and specific geographic areas, the overall
health of the Chesapeake Bay did not improve in 2008. The Bay continues to have poor water quality,
degraded habitats and low populations of many species of fish and shellfish. Based on these three
areas, the overall health averaged 38 percent, with 100 percent representing a fully restored ecosystem.
New restoration programs and projects were put in place in 2008, but resulted in only incremental
gains toward goals. The indicators for restoration averaged 61 percent, with 100 percent meaning that
all measures needed for a restored Bay have been implemented.
One of the greatest challenges to restoration is continued population growth and development, which
destroys forests, wetlands and other natural areas. The impact of human activity is overwhelming
nature and offsetting cleanup efforts.
Because the watershed's 17 million residents have a tremendous impact on its health, a section called
"How You Can Help" was added to this report. It shows simple actions that people can take to help
protect nature and reduce pollution. The Chesapeake Bay will only be restored through this type of
collective effort.

FACTORS IMPACTING THE BAY AND WATERSHED
Annual rain and snowfall affect how much water flows in rivers. The levels of pollution entering the Bay each
year generally correspond with the volume of water that flows from its tributaries.
River Flow: Total river flow to the Bay during the 2008 water year (October 2007-September 2008) was 37.5 billion
gallons per day (BGD). This is 3.5 BGD less than 2007 and 10 BGD less than the 47.2 BCD average flow from 1938-2008.
Nitrogen: Preliminary estimates indicate that 291 million pounds of nitrogen reached the Bay during 2008. This is 13
million pounds less than 2007 and 54 million pounds less than the 345 million pound average load from 1990-2008.
Phosphorus: Preliminary estimates indicate that 13.8 million pounds of phosphorus reached the Bay during 2008.
This is similar to 2007 and 7.5 million pounds less than the 21.3 million pound average load from 1990-2008.
Sediment: Preliminary estimates indicate that 3.3 million tons of sediment reached the Bay during 2008. This is
700,000 tons more than 2007 and 800,000 tons less than the 4.1 million ton average load from 1990-2008.
HOW YOU CAN HELP
Almost 17 million people live in the Chesapeake Bay watershed. The actions that residents take everyday affect
nature and impact the health of local creeks, streams and rivers, and ultimately the Bay. The effort to create
clean water in communities and restore the Chesapeake cannot be successful without the active involvement
of citizens throughout the watershed. Here are some key ways to help:
Pick up after your pet. Use phosphorus-free dish detergent.
Volunteer for a watershed group. * Drive your car less.
* Don't fertilize your lawn. Plant native trees and shrubs.
Install a rain barrel and rain garden.

HEALTH - 38 PERCENT
The Chesapeake Bay ecosystem remains severely degraded. The Bay's health is measured by
studying water quality, habitats, the lower food web and fish and shellfish. When all the goals for these
areas are reached, it should mean a restored Bay. In 2008, the Chesapeake Bay was only at 38 percent
of the desired health, which was the same as 2007. An increase in tidal tributary segments impaired
due to chemical contaminants and a drop in the blue crab population were primary reasons for a
lower score.
Water Quality - 21 percent
Water quality is the most important measure of the Chesapeake Bay's health. In 2008, water quality
was again very poor, meeting only 21 percent of the goals, the same as 2007. Pollution led to murky
water and algae blooms, which blocked sunlight from reaching bay grasses and created low levels of
oxygen for aquatic life. Chemical contaminants impaired more water in 2008, resulting in a 6 percent
decrease in that goal area.
Habitats and Lower Food Web - 45 percent
Overall, the vital habitats and lower food web that support life in the Chesapeake Bay continued to be
in bad shape in 2008, meeting 45 percent of the goals, the same as 2007. The positive news is that
there was a 7 percent gain toward the goal for underwater bay grasses. On the negative side, goal
achievement for algae fell 3 percent.
Fish and Shellfish - 48 percent
Most fish and shellfish populations in the Bay remain far below desired levels, and 2008 brought a
2 percent decrease in this goal area. This setback was driven by a drop of 23 million in the population
of spawning-age blue crabs, which lowered progress toward the species goal by 11 percent. Oyster
and shad populations remained at low levels.

RESTORATION - 61 PERCENT
To restore the Chesapeake Bay and its watershed, many measures must be put in place to reduce
pollution, restore habitats, manage fisheries, protect watersheds and foster stewardship. Progress toward
putting restoration measures in place continued in 2008, with a 4 percent gain, bringing the partnership to
61 percent of its goals. Population growth and development continue to hamper pollution-reduction efforts
and urban and suburban runoff remains the only source of pollution that is increasing. Steady progress was
seen in several areas, and the goal for land preservation has been met.

FACTORS
Everything that happens on land has an impact
on the water. The man-made pressures on the
Chesapeake Bay and its watershed began more
than 400 years ago, when the first European colony
was founded at Jamestown, Virginia, and Captain
John Smith led expeditions around the estuary.
During the four centuries that followed, the human
population swelled, forests were chopped down,
industrial activity ensued, fish and shellfish were
harvested, towns and cities were built, and toxic
chemicals were released into the environment.
These factors disrupted the natural functioning of the
entire ecosystem and led to a tremendous decline
in the Bay's health. Today, human activity continues
to drive the primary sources of pollution, which are
agriculture, urban and suburban lands, wastewater,
and air pollution.
AGRICULTURE
Agriculture covers about 25 percent of the watershed, representing the largest intensively managed land
use. There are an estimated 87,000 farms covering about 8.5 million acres. Agriculture is the number one
source of pollution to the Bay. Improperly applied fertilizers and pesticides flow into creeks, streams and
rivers, carrying excess nitrogen, phosphorus and chemicals into the Chesapeake Bay. Tilling cropland and
irrigating fields can cause major erosion. Additionally, the nutrients and bacteria found in animal manure can
seep into groundwater and runoff into waterways.
URBAN AND SUBURBAN LANDS
Human development, ranging from small subdivisions to large cities, is
a major source of pollution for the Chesapeake. In fact, because of the
region's continued population growth and related construction, runoff
from urban and suburban lands is the only source of pollution that is
increasing. These areas are covered by impervious surfaces - such
as roads, rooftops and parking lots - that are hard and don't let water
penetrate. As a result, water runs off into waterways instead of filtering
into the ground. This runoff carries pollutants including lawn fertilizer, pet
waste, chemicals and trash. Septic systems release pollution that eventually
ends up in the water. Developed areas also split up forests, decreasing their
filtering capacity.
10
-------
WASTEWATER
There is a tremendous volume of sewage that
must be processed in the watershed. The
technology used by the 483 major municipal and
industrial wastewater treatment plants has not
removed enough pollution, particularly nitrogen
and phosphorus. Upgrading these facilities so
they can remove more pollution from the water
is extremely expensive and takes time. While there has been significant progress
in improving treatment at many wastewater plants, numerous facilities still use
old technology. Also, population growth is increasing the need for wastewater
treatment, causing some facilities to be expanded.
AIR POLLUTION
When pollution is released into the air, it eventually falls onto land and water.
Even larger than the Chesapeake Bay's watershed is its airshed, the area from
which pollution in the atmosphere settles into the region. This airshed is about
570,000 square miles, or seven times the
size of the watershed. Nitrogen and chemical
contaminants - such as mercury and PCBs - from
air pollution contribute to poor water quality in
the region, and about half of these pollutants
come from outside the watershed. Air pollution is
generated by a variety of sources, including power
plants, industrial facilities, farming operations and
automobiles and other gas-powered vehicles.
OTHER
There are several other factors that impact the overall health of the ecosystem.
These include:
Climate Change: The Chesapeake region has already begun to see the
effects of global climate change in the form of sea level rise and higher
water temperatures. Scientists predict that climate change could also cause
a decrease in underwater grasses, more "dead zones" of low oxygen, more
annual precipitation and a resulting increase in the flow of pollution, fewer
wintering waterfowl, and a change in the types of plants and animals that
live in the area.
Invasive Species: Invasive species are animals and plants that are not native
to their habitat and negatively affect the invaded ecosystem. Once an invasive
species population is established it is unlikely to be completely eradicated.
In the Bay region there are more than 200 invasive species thought to cause
serious problems-the mute swan, nutria, phragmites, purple loosestrife, water
chestnut and zebra mussels are the species that pose the greatest threats.
Fisheries Harvest: The Chesapeake Bay and its tributaries have historically
been rich grounds for commercial and recreational fisheries. Demand for
seafood has driven these commercial fisheries, and crabbing and angling
have long been popular activities for residents. But these fisheries have put
tremendous pressure on the population of key Chesapeake species, such as
blue crabs and oysters.

CHAPTER 1 FACTORS IMPACTING BAY AND WATERSHED HEALTH
RIVER FLOW AND POLLUTANT LOADS
Importance: Each day, billions of gallons of fresh water flow through thousands
of streams and rivers that eventually empty into the Chesapeake Bay. That
water also carries polluted runoff from throughout the watershed. The amount
of water flowing into the Bay from its tributaries has a direct impact on how
much pollution is in the estuary - generally as river flow increases, it brings more
nitrogen and phosphorus to the Bay. The volume of river water flowing into the
Bay also affects the saltiness (salinity) of Bay waters. In addition, fast-moving and
turbulent river flow mixes in oxygen from the air, which is beneficial for aquatic life. Years with low or high amounts
of precipitation can result in changes to pollution levels in the Bay, but not mean the health of the watershed is
improving or declining.
To calculate the loads of nitrogen and phosphorus flowing to the Bay, scientists use a combination of water
samples and computer modeling. Whenever possible and practical, samples from rivers and wastewater pipes are
used to measure pollution levels. Using this technique, pollution loads can be calculated for almost 80 percent of
the watershed. For the remaining area, computer modeling is used to calculate pollution loads.
Status: River Flow: Total river flow to the Bay during the 2008 water year (October 2007-September 2008) was
37.5 billion gallons per day (BCD). This is 3.5 BCD less than 2007 and 10 BCD less than the 47.2 BCD average flow
from 1938-2008.
Nitrogen: Preliminary estimates indicate that 291 million pounds of nitrogen reached the Bay during 2008. This is 13
million pounds less than 2007 and 54 million pounds less than the 345 million pound average load from 1990-2008.
Phosphorus: Preliminary estimates indicate that 13.8 million pounds of phosphorus reached the Bay during 2008.
This is similar to 2007 and 7.5 million pounds less than the 21.3 million pound average load from 1990-2008.
Sediment: Preliminary estimates indicate that 3.3 million tons of sediment reached the Bay during 2008. This is
700,000 tons more than 2007 and 800,000 tons less than the 4.1 million ton average load from 1990-2008.

Population and Impervious Surface
LAND USE
How humans use the land has the greatest impact on the Chesapeake Bay and local waterways.
Natural areas like forests and wetlands have a positive effect on water quality, while areas developed
for farming or cities generally have a negative impact. The decline of the Chesapeake Bay is directly
linked to the rise in population of the watershed - since 1950 the number of residents has doubled.
Projections through 2030 show continued population growth, loss of natural areas and increases in
urban development, all of which are challenges to protecting and restoring the Chesapeake.
Even more influential than population growth is the corresponding development. People are moving
into sprawling suburbs and living in bigger houses on larger lots, causing forests, farms and other
valuable lands to be transformed into subdivisions, shopping centers and parking lots. This land
conversion severely impacts the health of streams, rivers and the Bay. Impervious surfaces such as
roads and rooftops do not allow water to filter into the ground. Instead, rainfall runs off, picking up
pollution and quickly carrying it into waterways. From 1990 to 2000, impervious surfaces increased by
41 percent - a rate five times greater than the 8 percent rate of population growth during that time.
Forests are the most beneficial use of land for Bay water quality. They capture, filter and retain water,
thereby reducing pollution and improving water quality. Forests also absorb air pollution and retain up to
85 percent of the nitrogen from sources such as automobiles and power plants. Forested areas reduce
erosion, control flooding and provide habitat for wildlife. In the 1600s, forests covered 95 percent
of the watershed. Now only 58 percent of the watershed is forested, and development is reducing
forests at the rate of 100 acres per day. Also because of development, forested areas are being split
into smaller parcels, which reduces their ability to improve water quality and provide wildlife habitat.

CHAPTER 2 ECOSYSTEM HEALTH
WATER QUALITY
For the Chesapeake Bay to be healthy and productive, the water must be safe for people and must
support aquatic life, such as fish, crabs and oysters. The water should be fairly clear, have enough
oxygen, contain the proper amount of algae and be free from chemical contamination.
However, the indicators in this section show that water quality in the Bay remains extremely poor
because of pollution from nitrogen, phosphorus, sediment and chemicals. Rain causes these pollutants
to runoff into local streams, creeks and rivers and the Bay itself. To improve water quality, the flow of
pollution must continue to be reduced. This will increase water clarity and oxygen levels in the Bay, and
will decrease harmful algae blooms and chemical contaminants.
Overall, Bay water quality is at 21 percent of the goal.
For more information, visit www.chesapeakebay.net/waterquality.aspx.
To improve water quality, the flow of pollution
must continue to be reduced.

DISSOLVED OXYGEN
Importance: When oxygen is in water, it is in a dissolved form.
The Chesapeake Bay's fish and shellfish need certain levels
of oxygen to survive and thrive. The necessary amount of
dissolved oxygen varies by species, season and location in the
Bay. Generally, higher levels of oxygen are needed in shallow
waters during the spring, when aquatic animals spawn. Slightly
lower levels of oxygen are acceptable at other times of the year,
particularly in deeper waters.
Status: The goal is for 100 percent of the tidal tributaries and
the Chesapeake Bay to meet Clean Water Act standards for
dissolved oxygen. When assessing water quality, regulators
examine conditions from the past three years to adjust for
annual weather-driven fluctuations. Data gathered from 2006
to 2008 indicate that about 16 percent of the combined volume
of open-water, deep-water and deep-channel water of the Bay
and its tidal tributaries met dissolved oxygen standards during
the summer months. This is an increase of 4 percent from last
year's assessment (also see dissolved oxygen map on page 7).
Dissolved Oxygen
Standards attainment: data represent 3 year period (data year and preceding 2 years).

WATER CLARITY
Importance: Clear water is a characteristic of a healthy
Chesapeake Bay. Good water clarity is one of the most important
factors in the growth of underwater grasses. These grasses
provide vital habitat for a number of aquatic animals. Clear water
allows sunlight to reach the plants, providing energy for them to
grow, and enables fish to see prey and avoid predators. Currently,
the flow of pollution into the Bay causes light-blocking algae to
grow and clouds the water with particles of dirt.
Status: The goal is for 100 percent of the Chesapeake Bay to
meet guidelines for water clarity. A device called a Secchi disk
is used to measure water clarity and the depth to which light
penetrates the water column during the growing season for
underwater bay grasses. Last year, 14 percent of tidal waters
met or exceeded thresholds for water clarity. This was a slight
increase from 2007, when about 12 percent met guidelines.

CHLOROPHYLL A
Importance: Scientists study chlorophyll a to determine the
amount of algae present in the Chesapeake Bay. Algae make
up the foundation of the food chain, supporting most aquatic
animals including oysters and fish. The right amount of algae is
needed for balance in the ecosystem. Too much nitrogen and
phosphorus pollution can cause algae blooms that block sunlight
from reaching underwater grasses, reducing habitat and the
oxygen necessary for life. Harmful algae blooms are an annual
problem in the Bay and its tributaries.
Status: The goal is for 100 percent of Chesapeake Bay
tidal waters to be below certain threshold concentrations of
chlorophyll a that are acceptable to underwater bay grasses.
Because pollution, weather and water temperature all
affect chlorophyll a, levels vary greatly by year, season and
location. Last year, 27 percent of tidal waters had chlorophyll a
concentrations below the threshold. This is an increase of
1 percent from 2007.

CHEMICAL CONTAMINANTS
Importance: Toxic chemicals found in the water, sediment
and fish of the Chesapeake Bay's tidal tributaries can have
adverse effects on the ecosystem and human health. Chemical
contaminants such as polychlorinated biphenyls (PCBs) can
accumulate in the tissues of fish and this can provide an
indication of the overall presence of these substances in the
ecosystem. These chemicals can build up in certain species of
fish to levels that can potentially be harmful to humans who
consume them.
Status: The Chesapeake Bay Program's goal is for 100 percent
of tidal tributaries to be unimpaired by chemical contaminants
such as metals, PCBs and tributyltin. Last year, 25 of the 89
monitored tidal segments (28 percent) were unimpaired by
chemicals. This represents a 6 percent decrease from 2007.
The other 64 segments contained a partial or full impairment.
There may be little positive change seen in the short term since
a majority of impaired waterways have persistent problems with
PCBs in fish tissues.

HABITATS AND THE LOWER FOOD WEB
For life to thrive in the Chesapeake Bay, high-quality food sources and habitats are required. Clams
and worms need an unpolluted environment at the bottom of the Bay. Abundant underwater grasses
and wetlands are vital to juvenile fish and crabs. For all aquatic life to flourish, the algae that make up
the foundation of the food web must be of the proper type and in the right amounts. The health and
abundance of these animals and habitats are gauges of the Bay's health.
The indicators in this section show that more underwater grasses and wetlands are needed both
for habitats and for their ability to filter pollution. Bottom habitat in the Bay and the health of algae
must improve.
Overall, 45 percent of the goals for Bay habitats and the lower food web have been achieved.
For more, visit www.chesapeakebay.net/habitats.aspx and
www.chesapeakebay.net/lowerfoodweb.aspx.
For life to thrive in the Chesapeake Bay,
high-quality sources of food and types of
habitat are req u i red.
BOTTOM HABITAT
Importance: The Bay's bottom is home to many species
including worms, small fish and shellfish such as clams, oysters
and mussels. These bottom-dwelling creatures are especially
sensitive to increased pollution and decreased oxygen. These
species serve as food for bottom-feeding fish and crabs. The
health of these creatures is a good indicator of long-term
conditions in the bottom habitat and the Bay overall, because
they do not move great distances and have certain predictable
responses to environmental stresses.
Status: A measurement called the Index of Biotic Integrity is
used to rate the health of bottom habitats on a scale of 1 to 5.
Each year, 250 random samples are collected throughout the
Bay and its tributaries. The goal is for all scores to be at least a 3.
In 2008, 42 percent of the area of the Bay and its tidal tributaries
met the restoration goals, which is the same as the previous
year. Low levels of dissolved oxygen are the primary cause of
bottom habitat degradation.

BAY GRASSES
Importance: Underwater bay grasses serve many essential
ecological functions and are among the most closely monitored
habitats in the Bay. Grasses provide critical shelter to many key
species such as young striped bass and blue crabs, improve
water clarity by helping sediment settle to the bottom, add
oxygen to the water and reduce shoreline erosion. Bay grass
abundance is an excellent barometer of the health of the Bay
because these grasses depend on good local water quality and
provide significant benefits to aquatic life.
Status: The goal is to have 185,000 acres of underwater bay
grasses in the Chesapeake Bay by 2010, which represents the
documented acreage found from the 1930s until the present.
Last year, there were 76,861 acres of bay grasses throughout
the Bay, which was 42 percent of the goal and an increase
of 11,984 acres from 2007. In 2008, grasses in the Upper
Bay covered about 22,954 acres (97 percent of the area's
23,630-acre goal). Middle Bay grasses covered 34,521 acres
(30 percent of the 115,229-acre goal for the area), and grasses
in the Lower Bay covered 19,386 acres (42 percent of the area's
46,030-acre goal).
Bay Grasses

Data and methods: www.chesapeakebay.net/status_baygrasses.aspx
PHYTOPLANKTON
Importance: Algae, or phytoplankton, are especially sensitive
to changes in pollution levels, water clarity, temperature and
salinity, and therefore serve as an excellent indicator of the
health of the Bay's surface waters. While algae also make up
the base of the food web in the Bay ecosystem, too much or
the wrong type of algae can be detrimental to the overall health
of the Bay by decreasing oxygen, blocking sunlight and harming
aquatic life. In some cases, algae blooms can negatively impact
human health as well.
Status: A measurement called the Index of Biotic Integrity is
used to rate the health of phytoplankton on a scale of 1 to 5.
Scores are generated using monthly samples taken from 31
stations during the spring and summer. The goal is for all scores
to be at least a 3. Last year, 53 percent of the Bay's surface
waters met the goal, a decrease of about 3 percent from 2007.
Water clarity is currently too poor and pollution levels too high
to consistently support healthy phytoplankton communities.
Algae blooms are still frequent, harmful algae species are often
abundant and algal cells exhibit signs of stress.

WETLANDS
Importance: In addition to being places of tremendous
beauty, wetlands connect the land to the water. Throughout
the Chesapeake Bay, these areas of transition provide unique
habitats for a rich diversity of land animals and aquatic life.
Wetlands also act as sponges and natural filters by absorbing
runoff and removing pollution from water before it enters
streams, creeks, rivers and the Bay. But the Chesapeake's
wetlands are fragile and threatened by shoreline development,
sea level rise and invasive species.
Status: This indicator is used not to track progress toward a
goal, but to measure how many acres of tidal wetlands are in the
Bay and identify trends. As of 2005, there were approximately
283,946 acres of tidal wetlands. There was a 2,600-acre loss
between 1996 and 2005. While the decline is not significant
on a baywide scale, certain areas are suffering the losses. For
example, at Blackwater National Wildlife Refuge on Maryland's
Eastern Shore, scientists have documented losses in wetlands
due to sea level rise, land subsidence, coastal erosion and the
invasive species nutria.

CHAPTER 2 ECOSYSTEM HEALTH
FISH AND SHELLFISH
For the Chesapeake Bay to be considered restored, there must be healthy and abundant fish and shellfish.
Blue crab, oyster, striped bass, shad and menhaden are some of the Bay's most iconic species. These fish
and shellfish are an essential part of the region's commercial fisheries, recreational activities, and cultural
and culinary identity. They also play critical roles in the Bay's ecosystem and require clean water, ample
aquatic habitat and properly managed fisheries to be healthy and reproduce.
However, the indicators in this section reflect that the Chesapeake's fish and shellfish suffer from polluted
water, lack of habitat and disease. They also face other challenges, such as overharvesting pressures and
reduced food sources.
Overall, 48 percent of the goals have been met for fish and shellfish.
For more, visit www.chesapeakebay.net/fish.aspx and www.chesapeakebay.net/crabsandshellfish.aspx.
BLUE CRAB
Importance: Perhaps no species
is more closely associated with the
Chesapeake Bay than the blue crab.
It is estimated that one-third of the
nation's blue crab catch comes from the Bay. Good water
quality and adequate habitat, particularly of underwater
grasses that provide shelter and food, are essential for the
crabs' health and population growth. Harvest restrictions
are also required to prevent removal of too large a segment
of the population. The species has been impacted by
overexploitation, pollution and reduced habitat.
Status: The goal is to have 200 million blue crabs that are
at least one year old in the Bay. This abundance of crabs
can result in a harvest of 60 million to 65 million pounds
each year while still preserving 20 percent of the spawning
population. Last year, the population of spawning-age blue
crabs in the Bay was 120 million, or 60 percent of the goal.
This is a substantial decrease from 143 million in 2007,
which was 71 percent of the goal.
Blue Crab Abundance
20
Data and methods: www.chesapeakebay.net/status_bluecrab.aspx
OYSTERS
Importance: Oysters join blue crabs
as one of the most valuable species
in the Chesapeake Bay. These
bivalves have an incredible ability to
filter water, which increases water
clarity. It has been estimated that at their historic population
peak, oysters filtered all of the Bay's water in less than one
week - it takes about one year for the current population to do
so. Oysters have also constituted one of the Bay's most valuable
commercial fisheries for more than a century. But historic
overharvesting, pollution and the diseases Dermo and MSX
have caused a severe decline in oyster numbers.
Status: The goal is to achieve at least a tenfold increase in
native oysters in the Chesapeake Bay by 2010, based on 1994
levels, which would equal 31.6 billion grams of oyster biomass.
Based on the most recent data from 2007, there are 2.73 billion
grams of oyster biomass, or about 9 percent of the goal. The
2007 level of oyster abundance was not a significant change
from 2006 and is near the baywide average of 9.6 percent from
1994-2007.
Oysters Abundance

Data and methods: www.chesapeakebay.net/status_oyster.aspx
-------
STRIPED BASS
Importance: The Chesapeake Bay is a primary spawning and
nursery habitat for striped bass on the Atlantic Coast. Striped bass
support one of the most important commercial and recreational
fisheries on the Atlantic seaboard. A fishing moratorium during the
late 1980s and commercial quotas and recreational harvest limits
set since 1990 have restored the stock. However, scientists are
concerned about the high prevalence of disease (mycobacteriosis)
in the fish and continue to research the problem. Because striped
bass are among the Bay's top predators, scientists are also
concerned about whether there is enough prey to adequately
support the population.
Status: The goal for a restored population of striped bass is to
have a spawning stock biomass equal to the averages from
1960-1971, which is 82.7 million pounds of the females. The goal
for striped bass has been met: 89.6 million pounds of spawning
stock in 2006 is 108 percent of the goal. This is less than the peak
of 113 million pounds in 2003 and a measure of 100.2 million
pounds in 2005.
Striped Bass Abundance
108%
Data and methods: www.chesapeakebay.net/status_stripedbass.aspx
Importance: American shad form an important link in the
Chesapeake Bay food web. Shad feed on plankton and small
fishes. In turn, they are preyed upon by larger fish, including
bluefish, weakfish and striped bass. Historically, local economies
flourished from the annual shad run in the spring, when the
fishes' upriver migration begins. But shad populations were
decimated in the 1970s by overfishing, pollution and dams
and other blockages that prevent the fish from spawning in
upstream habitats.
Status: The goal for American shad is based on an estimate of
the spawning shad stock in major river systems, some with fish
passage systems in place to bypass existing blockages by dams
and other barriers. Based on the most recent data from the
James, Potomac, Susquehanna and York rivers, the estimates of
baywide shad abundance is 23 percent of goal achieved, which
is an increase of almost 2 percent from 2007.

Data and methods: www.chesapeakebay.net/status_shad.aspx
Importance: Menhaden play a key ecological role in the
Chesapeake Bay because they are food for top predators such
as striped bass and have a great ability to filter the water. The
menhaden fishery is also one of the most productive on the
Atlantic Coast, providing fish meal, fish oil and bait. Menhaden
that inhabit the Chesapeake Bay are part of a coastal Atlantic
stock, and while populations along the Atlantic Coast are
healthy, some scientists are worried about low abundance in
the Chesapeake.
Status: There is no goal for this indicator because there is no
estimate of menhaden population in the Chesapeake Bay. At this
time, it is not technically possible to set specific targets or goals.
However, researchers track juvenile menhaden abundance
by casting nets and recording the number of hauls where
menhaden are present. Last year, the proportion of positive
hauls was 18 percent, which was a 4 percent decrease
from 2007.

HEALTH OF FRESHWATER STREAMS AND RIVERS
Importance: Healthy freshwater streams and rivers have local and regional importance.
Clean waterways are a benefit to residents who use them for recreation, drinking water,
business and other purposes. The watershed's streams, creeks and rivers also eventually
flow into the Chesapeake Bay, so their water quality has a direct impact on the health of
the estuary.
An effective way to measure the health of freshwater streams and rivers is to study
the many tiny creatures that live in these waters. The abundance and diversity of
snails, mussels, insects and other bottom-dwelling organisms - known as benthic
macroinvertebrates - are good indicators of the health of streams. Because the
communities of these creatures can't move very far and they respond in certain
predictable ways to pollution and stresses in the environment, they provide valuable
information about the health of the water.
There are many different causes of polluted streams and rivers across the Chesapeake
Bay watershed. Benthic macroinvertebrates are generally harmed by pollutants such as
metals, acidity, sediment, pesticides, nitrogen and phosphorus. These pollutants come
from sources such as mining, agriculture, urban and suburban runoff, automobile and
power plant exhaust, and wastewater treatment facilities.
Status: The health of streams varies from very poor to excellent throughout the
Bay watershed (see results on the map). Although sampling densities differ, some
generalizations about the health of the watershed's streams can be made. For
instance, streams tend to be in very poor to fair condition around large urban areas
such as metropolitan Washington, D.C. (see map inset). Streams in heavily farmed
or mined areas are also often in very poor to fair condition. In contrast, streams
tend to be in good to excellent condition in forested areas with ample natural
habitat and low levels of pollution, such as in the southwestern Pennsylvania
region of the watershed (see map inset).
Overall, the analysis showed that out of 3,291 sampling sites in the watershed,
1,632 were in very poor or poor condition and 1,056 were in good or excellent
condition. The results from this indicator will help managers and watershed groups
focus their efforts to restore streams in need of improvement and protect the
quality of the healthiest streams.
The watershed's streams, creeks and rivers eventually flow into the Bay, so
their water quality has a direct impact on the estuary.

REDUCING POLLUTION
The Chesapeake Bay cannot be restored without water that is clean, clear and rich in oxygen.
Currently the Bay and its rivers receive too much pollution for the ecosystem to remain healthy.
The primary sources of pollution are agricultural land, wastewater treatment plants, urban and
suburban runoff, and air pollution.
The Chesapeake Bay must meet a "pollution diet" to reduce pollution and restore the estuary.
The indicators in this section show progress toward putting pollution reduction controls in place.
The states in the Chesapeake Bay watershed and the District of Columbia have developed
strategies for reducing pollution in their jurisdictions. Progress is measured by using data from
monitoring and computer simulations.

AGRICULTURE
Importance: About 25 percent of the land in the Chesapeake Bay
watershed is dedicated to agriculture. While fertilizers, pesticides,
manure and tilled soil are beneficial to crops, they become
pollutants when water from irrigation and precipitation washes
them into local waterways. Chesapeake Bay Program partners are
working with farmers to help control pollution from the watershed's
8.5 million acres of farmland. Farmers are utilizing conservation
practices such as nutrient management plans, cover crops,
vegetative buffers, conservation tillage and animal manure and
poultry litter controls.
Status: The partners have achieved 50 percent of the goal for
agricultural nitrogen control efforts, a 2 percent increase from
2007. About 49 percent of the goal for agricultural phosphorus
control efforts has been met, a 2 percent decline from the previous
year. Partners have achieved 48 percent of the goal for sediment
pollution control efforts, the same as 2007. These estimates do

WASTEWATER
Importance: There are 483 major wastewater treatment plants
in the Chesapeake Bay watershed. Historically, the high amounts
of nitrogen and phosphorus discharged by these facilities have
degraded local waterways and the Bay. And as the population of
the watershed continues to grow, so does the volume of water
requiring treatment. Bay jurisdictions have reduced the pollution
in wastewater through a new permitting process that requires
plants to upgrade the processes and technology they use
for treatment.
Status: The partnership has achieved 67 percent of the
wastewater nitrogen reduction goal, which is a 2 percent
decrease from 2007. Progress toward the wastewater
phosphorus reduction goal stands at 91 percent, which is a
4 percent increase from the previous year. These decreases in
the amount of nutrients discharged from wastewater treatment
plants account fora large portion of the estimated nutrient
reductions in the watershed to date.

URBAN/SUBURBAN LANDS AND
SEPTIC SYSTEMS
Importance: When water from storms runs off roads, parking
lots, rooftops and other hard surfaces, it carries pollution to
local waterways and the Chesapeake Bay. Runoff from urban
and suburban land is currently the only source of pollution that
is increasing. This is due to continued population growth and
related development. To address this problem, state and local
governments are strengthening stormwater regulations and
working to manage growth in a sustainable way. This includes
an emphasis on using green infrastructure in the construction
and retrofitting of buildings, including homes.
Status: Population growth and development are offsetting the
Chesapeake Bay Program's efforts to reduce pollution from
urban and suburban land and septic systems. The increases
in population and construction have also surpassed the gains
achieved from improved landscape design and stormwater
practices. Additionally, it is still challenging to comprehensively
account for on-the-ground control practices.

AIR POLLUTION
Importance: About one-third of the nitrogen that reaches
the Chesapeake Bay comes from emissions into the air from
automobiles, industries, power plants and similar sources. This
pollution eventually falls onto water surfaces and land where it
can be washed into waterways. About half of the air pollution
comes from outside the Chesapeake Bay watershed, including
places such as Ohio, South Carolina and Canada. The partnership
is relying on federal and state laws that regulate emissions to
significantly reduce airborne nitrogen.
Status: The Chesapeake Bay Program has met 9 percent of
the goal for air pollution controls necessary to reduce nitrogen,
which is a 1 percent increase from the previous year. While
progress in this area is limited, it is expected to accelerate over
the next several years as recently approved air pollution control
measures take effect.

RESTORING HABITATS
High-quality habitats are required for the overall balance of the Chesapeake Bay ecosystem and
the health of fish, crabs, birds and other wildlife. Habitats provide the food, shelter and spawning
areas needed for animals to survive. The restoration of habitats throughout the watershed is also
beneficial for other reasons, from improving water quality to reducing erosion to increasing
recreational opportunities.
Partners of the Chesapeake Bay Program have focused their habitat restoration efforts on four key
areas. Planting of underwater grasses is critical because these areas are used by crabs, fish and
waterfowl. Work to restore oyster reefs continues since they can provide habitat for communities of
fish and bottom-dwelling organisms. Streams and rivers are being reopened to allow migratory fish to
swim upstream to spawn and to increase habitat for local fish populations. While wetlands play many
vital roles, they are especially valuable places for a diverse array of land and aquatic species.
Overall, the partnership is 55 percent of the way toward its goal for restoring habitats.

Habitats provide the food, shelter and spawning
areas needed for animals to survive.

PLANTING BAY GRASSES
Importance: Underwater bay grasses depend on good water
quality to grow and so that grass beds can naturally expand. For
this reason, efforts to reduce pollution in the water can have
a positive influence on restoring bay grasses. In addition to
pollution reduction measures, there are a number of programs to
collect seeds and plant bay grasses in the Bay and its tributaries.
These plantings are located in areas without bay grasses but
where water quality should support growth. These newly
established grass beds then produce seeds, allowing for natural
revegetation of adjacent areas.
Status: In 2003, Chesapeake Bay Program partners seta goal
to plant 1,000 acres by 2008. Last year, 8.5 acres of bay grasses
were planted, bringing the total to 148 acres. This represents
15 percent of the goal and a 1 percent increase from 2007.
Future plantings are dependent on available funding.

RESTORING OYSTER REEFS
Importance: Restoring oyster reefs throughout the Chesapeake
Bay is a primary part of the strategy for increasing the native
oyster population. To rebuild reefs, both oyster shells and
alternate materials for oysters to grow on are planted in the
Bay. Also, oysters are grown in hatcheries and then planted in
natural and man-made habitats. Restoring reefs could increase
the population of spawning adult oysters and, in turn, larval
production. Many of these rebuilt reefs are designated as oyster
sanctuaries and protected from harvest.
Status: The Chesapeake Bay Program has a goal of
implementing restoration practices on 2,466 acres of oyster bar
and reef habitat between 2007 and 2010. Last year, restoration
efforts took place on 943 acres. This brings the total acreage to
1,719, or 70 percent of the goal. The success of these habitat
restoration techniques has been limited by numerous factors,
including disease, poor water quality, habitat degredation and
fishing pressure. It should be noted that before this goal was
set, a total of 15,648 acres were rehabilitated between 1994
and 2006.

REOPENING FISH PASSAGE
Importance: Dams, culverts and other barriers currently block
the movement of migratory fish to spawning grounds and
reduce the habitat of local fish species in streams, creeks
and rivers. Throughout the Chesapeake Bay watershed,
these barriers are being removed or new lifts, ladders and
passageways are being installed to allow the fish to swim
upstream. Priority is given to fish passage restoration projects
that open large stretches of habitat, remove dams, enhance the
passage of migratory fish and remove impediments in streams
that were previously impaired by acid mine drainage. Many of
these projects also restore the flow of waterways and reduce
the accumulation of sediment.
Status: The Chesapeake Bay Program's fish passage efforts are
long-standing and generally successful. From 1988 through 2005,
the partners opened 1,838 miles offish passage, surpassing their
original 1,357-mile restoration goal. In early 2005, Chesapeake
Bay Program partners committed to increasing the restoration
goal to 2,807 miles by 2014. Last year, 51 miles offish passage
were restored. This brings the total to 2,317 miles, or 83 percent
of the goal, a 2 percent increase from 2007.

RESTORING WETLANDS
Importance: Because of the many benefits of wetlands -
providing habitat, filtering water, preventing erosion -work is
ongoing to increase the acreage of these areas. This involves
establishing wetlands where they did not exist or reestablishing
former wetlands to their natural state. Removing invasive
species is also a way to rehabilitate that degraded wetlands.
Additionally, these critical habitats are often protected through
land purchases or conservation easements.
Status: Chesapeake Bay Program partners have a goal of
restoring 25,000 acres of wetlands by 2010. Last year, 472 acres
of wetlands were established or reestablished in Maryland,
Pennsylvania, Virginia and the District of Columbia. The restored
total stands at 13,005 acres, or 52 percent of the goal.

CHAPTER 3 RESTORATION EFFORTS
MANAGING FISHERIES
Importance: The Chesapeake Bay fishing industry holds tremendous commercial,
cultural and historical value. Managing the fisheries for blue crabs, oysters, striped
bass, shad and menhaden is also critical to restoring and protecting the population
of these species and their important place in the ecosystem. To improve fisheries
management, the partners of the Chesapeake Bay Program are developing
ecosystem-based plans. This type of comprehensive approach involves three
components: actions that address a single species, a focus on multispecies
interactions and consideration of the entire ecosystem. Improving water quality
and restoring habitats are also part of this management approach.
Status: While significant effort went toward improving the management of
Chesapeake Bay fisheries this year, very few of these efforts resulted in the
implementation of ecosystem-based actions or the completion of new plans.
Overall, the partnership has achieved 51 percent of its goal for developing
ecosystem-based management for fisheries.
For more, visit www.chesapeakebay.net/statusjnanagingfisheries.aspx.
OYSTERS
Importance: Managing the oyster fishery requires a multi-
pronged approach. Currently, there are minimum size limits,
bushel limits, gear restrictions and seasonal and geographical
closings. Additionally, sanctuaries are used to protect oysters
from harvest and increase the population of spawning adult
oysters. Restoration efforts that focus on rebuilding reefs and
planting oysters also benefit the fishery. It continues to be
challenging to identify the level of harvest that supports the
fishery but does not compromise restoration efforts.
Status: The score for oyster fishery management increased
by 2 percent, from 37 to 39 percent, because of three actions
taken during 2008. First, a Programmatic Environmental Impact
Statement that evaluates alternatives for restoring the oyster
population was released for public comment. Second, Maryland
completed the first year of a pilot study on how best to measure
the oyster biomass, which will improve population assessment
and management. Finally, development of oyster aquaculture
is progressing, which could reduce harvest pressure on wild
oysters and provide a viable product for the industry.
ATLANTIC MENHADEN
Importance: Atlantic menhaden have a unique role in the
ecosystem as filter feeders and prey for top predators such
as striped bass, which requires a multi-species management
plan. Menhaden migrate into Chesapeake Bay and are part of
a larger stock along the Atlantic Coast. The coastal population
is healthy, but there are concerns about declining numbers of
young menhaden in the Bay. In response, a five-year cap on
commercial harvest within the Bay was put in place in 2006.
During this time, a variety of projects will occur.
Status: The score for Atlantic menhaden fishery management
did not change. Some research projects were completed but
did not lead to any changes to management; other projects are
still underway. Additional research is needed, including linking
changes in the environment to recruitment and growth, using
remote sensing technology to determine menhaden distribution
and abundance, understanding larval movement into the Bay
from the mid-Atlantic spawning areas, and determining the
level of removal of menhaden by predators such as striped
bass. A menhaden team was organized to begin developing an
ecosystem-based fishery management plan and background
briefs will be ready by March 2009.
AMERICAN SHAD
Importance: Overfishing, water pollution and dams that
prevented access to spawning areas led to a greatly diminished
stock of American shad in the 1970s. This led two states to
implement a fishing moratorium: Maryland in 1980 and Virginia
in 1994. In addition to the shad fishing moratorium, researchers
and managers are currently stocking hatchery-raised fish,
removing dams and installing fish passage on key Bay tributaries
to restore this species. Catch limits and safe levels of harvest
must be developed before the Bay fishery can be reopened.
Also, because shad spend much of their lives in coastal Atlantic
waters, continued management by the Atlantic States Marine
Fisheries Commission is crucial.
Status: The score for American shad fishery management has
not changed. However, new coastal management measures
are under development. In response to the 2007 coastal stock
assessment, the Atlantic States Marine Fisheries Commission is
developing biological reference points for managing the stocks,
developing stock restoration goals, decreasing and restricting
fisheries, and planning to develop new management strategies
in 2009.

STRIPED BASS
Importance: The Chesapeake Bay is the primary spawning
and nursery habitat for up to 90 percent of the Atlantic Coast's
striped bass population. The Bay's fishery for striped bass
collapsed during the 1970s and 1980s as the population of this
species plummeted. But fishing moratoriums and management
led to a rebound and the moratorium was lifted in 1990. Fishery
management currently involves monitoring, catch quotas and
seasonal closings. Ecosystem-based fisheries management is
especially important for striped bass because they are among
the Bay's top predators, feeding on Atlantic menhaden. An
annual cap on the commercial harvest of menhaden is in place
from 2006 to 2010.
Status: The score for striped bass fishery management did
not change. While some important research occurred last year,
it has not yet been included into an ecosystem-based fishery
management plan. During 2008, biological briefs and background
information for such plans were completed. Research continued
on the disease mycobacteriosis. Modeling results provided the
first evidence of mycobacteriosis-associated mortality in the
striped bass population in the Bay. Scientists also identified
priority areas for protection and restoration based on the location
of striped bass spawning and larval distribution and water
quality conditions.
BLUE CRABS
Importance: Blue crabs make up the most valuable commercial
fishery in the Chesapeake Bay. To both protect the fishery and
restore the spawning stock, the harvest is regulated through
a minimum catch size, gear restrictions and seasonal harvest
limits. An annual winter dredge survey provides estimates of the
percentage of the crab population that is removed by harvest.
Additionally, because blue crabs play important roles as both
predator and prey, scientists have studied their interactions with
striped bass, their predators.
Status: The score for blue crab fishery management increased
by 2 percent, from 56 to 58 percent, because of several actions
during 2008. Commercial harvest regulations were developed
by Maryland and Virginia to reduce the harvest of mature female
blue crabs by 34 percent. New Maryland regulations include an
early seasonal closure, increased size limits for peeler crabs and
commercial catch limits. The recreational fishery was prohibited
from harvesting any female crabs. New Virginia regulations
include an extended closure of the sanctuary, elimination of the
winter dredge fishery, increased size limits for peeler crabs and
a gear reduction plan. Also, the commercial blue crab fishery
was declared a state of disaster by the U.S. Department of
Commerce. Each state will receive $10 million over the next
three years for watermen projects such as habitat restoration,
fishery monitoring, industry diversification and aquaculture.

CHAPTER 3 RESTORATION EFFORTS
PROTECTING WATERSHEDS
A watershed is an area of land that drains to a particular river, lake, bay or other body of water. Within
the Chesapeake Bay watershed, there are tens of thousands of smaller watersheds that drain into
local waterways, which all eventually flow into the Bay. Protecting the region's watersheds is critical
because what happens on land has a direct impact on the water. This effort is also important because
the human population in the Chesapeake Bay watershed is increasing, bringing construction and
suburban sprawl. This growth and development reduce natural areas such as forests and wetlands.
To protect watersheds, Chesapeake Bay Program partners continue to plant buffers of trees, bushes
and other vegetation along waterways. Efforts also involve permanently preserving land from
development throughout the watershed and preventing sprawl through the use of statewide smart
growth programs. Management plans are development to guide the protection and restoration of
nature in watersheds of all sizes.
Overall, the partnership is 74 percent of the way toward its goals for protecting watersheds.
For more, visit www.chesapeakebay.net/status_protectingwatersheds.aspx.
A watershed is an area
of land that drains to a
particular river, lake, bay
or other body of water.
30
-------
RESTORING FOREST BUFFERS
Importance: Trees, bushes and other plants that line the banks
of waterways are called forest buffers. This vegetation provides
habitat for wildlife, stabilizes stream banks from erosion and
keeps river waters cool, an important factor for many fish.
Well-maintained forest buffers also naturally absorb pollution,
helping to improve water quality in neighboring streams and
rivers as well as downstream. Work is ongoing to plant buffers
along thousands of miles of streams, creeks and rivers in the
Chesapeake Bay watershed.
Status: Chesapeake Bay Program partners achieved their
original 2010 buffer restoration goal of 2,010 miles well ahead
of schedule and in 2003 set a new goal to conserve and restore
forests along at least 70 percent of all streams and shoreline in
the watershed, with a near-term goal of at least 10,000 miles by
2010. From September 2007 to August 2008, about 449 miles
of forest buffer was planted fora total of 6,172 miles. This is
62 percent of the goal, a 5 percent increase from last year.
Restoring Forest Buffers
Data and methods: www.chesapeakebay.net/status_forestbuffers.aspx
PRESERVING LANDS
Importance: Land in the watershed is a finite and fragile
resource, and what happens on land has an enormous impact
on local waterways. Population growth and construction have
increased the need to preserve natural places such as forests.
Parks, wildlife refuges and other preserved lands provide habitat
for animals and filter pollution before it reaches the Bay and its
tributaries. Chesapeake Bay Program partners have pursued land
preservation by buying property, accepting donations, arranging
for easements and purchasing development rights.
Status: Maryland, Pennsylvania, Virginia and the District of
Columbia have a commitment to permanently protect from
development 20 percent of their combined 34 million acres by
2010. Last year, 115,613 acres were preserved. This brings the
total land protected to 7.32 million acres, which surpasses the
goal two years before the deadline. Preservation efforts will
continue because in December 2007 the Bay states committed
to permanently conserve an additional 695,000 acres of forested
land throughout the watershed by 2020.
Preserving Lands
Data and methods: www.chesapeakebay.net/statusjandspreseived.aspx
DEVELOPING WATERSHED
MANAGEMENT PLANS
Importance: Protecting watersheds is a complicated and
challenging task. To successfully protect and restore stream
corridors, forest buffers, wetlands, parks and other natural
spaces, watershed management plans are needed. These
strategic guides preserve not only watershed health, but also
the quality of life in communities. For management plans to be
acceptable, they must address conservation of natural areas,
aim to improve habitat and water quality, have the necessary
tools and resources, and garner local support.
Status: The Chesapeake Bay Program has a goal of developing
and implementing watershed management plans for two-thirds
of the 34 million acres in Maryland, Pennsylvania, Virginia and
the District of Columbia. Last year, watershed plans were added
for 827,204 acres in these jurisdictions, bringing the total to
13.9 million acres. This represents 61 percent of the goal,
which is a 4 percent increase from 2007.

FOSTERING STEWARDSHIP
For the Chesapeake Bay to be restored and protected, the region's citizens, communities and other
stakeholders must be actively involved. Fostering stewardship of the Bay and its watershed is a top priority
for Chesapeake Bay Program partners. Public access is vital to building personal connections to nature.
There are also various communication and outreach programs underway to provide information that engages
people in the restoration effort. Environmental education opportunities for students and teachers are another
area of emphasis. The ultimate measure of stewardship, however, is citizen and community action.
The indicators in this section reflect steady progress in providing public access and enhancing
environmental education. But programs to increase the number of communities and businesses engaged in
restoration have stalled. At the same time, a new project to measure citizen action has been launched.
Overall, the partnership is 65 percent of the way to its goal for fostering stewardship.
For more, visit www.chesapeakebay.net/stewardshipanded.aspx.
COMMUNICATIONS AND OUTREACH
Sharing the most current information about the health of the Chesapeake Bay and restoration work is an
important part of fostering stewardship. Partners of the Chesapeake Bay Program believe that knowledge
empowers citizens and enables them to help protect nature. There are many ways the Chesapeake Bay
Program communicates with the public, including its website, email updates and a new blog. Outreach efforts
are also ongoing and involve giving public presentations, participating in environmental events and conferences,
and distributing news releases and publications. Members of the public are encouraged to sign up to receive
regular updates and to visit the websites often for the latest news.
Bay News: This daily email provides links to media coverage from around the watershed. To sign up, visit
www.chesapeakebay.neVthebayinthenews.aspx.

-------
PUBLIC ACCESS
Importance: For people to deeply value the Chesapeake Bay
and the thousands of streams, creeks and rivers that flow into
it, they need access to nature throughout the watershed. This
allows people to enjoy activities such as fishing, swimming,
kayaking, hiking and picnicking, which creates a personal
connection with nature and builds public support for restoration
efforts. Program partners continue to increase and improve
access in an environmentally sensitive manner through the
Chesapeake Bay Gateways Network, water trails and the
Captain John Smith Chesapeake National Historic Trail.
For more information and a map of public access locations, visit
www.chesapeakebay.neVpublicaccess.aspx.
Status: There are multiple goals within the larger public
access goal. These include expanding by 30 percent the
system of public access points to the Bay, its tributaries and
related sites; developing partnerships with at least 30 sites to
enhance interpretation of Bay-related resources and stimulate
volunteering; and increasing designated water trails in the Bay
region by 500 miles. Last year, 11 public access sites were
acquired, developed or enhanced, bringing the total to 754.
Six new Gateways sites were added, raising the total to 161.
About 23 miles of water trails were developed, for a total of
2,184 miles. With these additions, the partnership has reached
98 percent of its public access goal.
Public Access
Data and methods: www.chesapeakebay.net/status_publicaccess.aspx
EDUCATION AND INTERPRETATION
Importance: Perhaps the best way to foster stewardship of the
Chesapeake Bay is through education, especially for the millions
of children who live in the watershed. The long-term health
of the environment will depend on their interest and ability to
protect nature. Chesapeake Bay Program partners continue to
promote environmental education in classrooms at elementary,
middle and high schools, with a focus on providing a Meaningful
Watershed Educational Experience (MWEE) for all students
before they graduate. Partners also provide lifelong learning
opportunities for citizens of all ages, with information and
interpretation at a multitude of locations in the region.
Status: In 2000, the partnership set a goal to provide a MWEE
for every student in the watershed before graduation from
high school. In 2008, the partnership increased the number of
experiences provided for student to three, which will mean a
MWEE in elementary, middle and high school. About 73 percent
of the goal was achieved during the 2007-2008 school year.
Also, since 2002 the NOAA Bay Watershed Education and
Training Program (B-WET) grant program has funded MWEEs for
more than 150,000 students and training opportunities for more
than 15,000 teachers.

CITIZEN AND COMMUNITY ACTION
Importance: The Chesapeake Bay and its watershed will never
be restored and protected without the action of its 17 million
residents and the involvement of local government. That many
people can surely have a tremendous impact if they are actively
involved in the cleanup. A top priority for the Chesapeake Bay
Program is encouraging the public to participate in activities
that are positive for nature, including at home, at work and in
the community. It is also important for towns and cities to put
measures in place that create clean water.
Status: For community action, the partnership has a goal of
establishing 330 local governments, or 20 percent of those in
the watershed, as Bay Partner Communities. These are towns
and cities that are implementing Bay-friendly measures. To
date, 77 local governments have been awarded Bay Partner
Community status, which is 23 percent of the goal. However,
the program is no longer funded.
To measure citizen action, the first Chesapeake Volunteer Count
was launched. This effort asked watershed organizations to report
the number of volunteers for the year. Based on preliminary data
collected from 73 Chesapeake Bay watershed organizations,
50,590 volunteers participated in restoration activities in 2008.
The majority of the organizations reported that volunteerism rates
remained the same or increased from 2007.

CHAPTER 3 RESTORATION EFFORTS
RESTORATION HIGHLIGHTS
At the 2007 Chesapeake Executive Council meeting,
members selected topics critical to restoration
to be their "champion roles." Chesapeake Bay
Program partners have since made significant
progress on issues such as promotion of low-impact
development, support of agricultural conservation
practices and improvement of wastewater treatment.
The partnership will continue to take this type of
targeted action on vital issues in 2009.
ACCOUNTABILITY - MARYLAND
Through the BayStat program, Maryland has secured and will award annual funding to address
non-point-source pollution; appointed a scientific advisory panel; strengthened its Critical Area
Program, including provisions to significantly change how coastal shorelines are stabilized; doubled
annual cover crop enrollment to 400,000 acres; and targeted Program Open Space for priority
conservation areas.
AGRICULTURE CONSERVATION PRACTICES - VIRGINIA
Virginia has allocated $20 million for agricultural best management practices in the commonwealth,
the largest amount ever appropriated in the history of Virginia's agricultural best management
practice cost-share program.
BLUE PLAINS - CHESAPEAKE BAY COMMISSION
The Chesapeake Bay Commission met with members of Congress to advocate for more federal
support to upgrade the Blue Plains wastewater facility and helped arrange congressional tours and
briefings on Blue Plains. These efforts resulted in congressional hearings in May, and the House
and Senate appropriated $14 million and $16 million, respectively, for combined sewer overflow
(CSO) upgrades.
BLUE CRAB RESTORATION - MARYLAND, VIRGINIA
To rebuild the blue crab population, Maryland and Virginia agreed to implement new bistate
regulations to reduce the harvest of female crabs in the Chesapeake Bay by at least 34 percent. The
two states have agreed to keep crab exploitation at a target level of 46 percent to provide a buffer
against overfishing in the future.
BIOFUELS - PENNSYLVANIA, CHESAPEAKE BAY COMMISSION
Together, Pennsylvania and the Chesapeake Bay Commission convened a 22-member Biofuels
Advisory Panel that met throughout the year, culminating with the release of the Next-Generation
Biofuels report at the Chesapeake Bay Biofuels Summit in Harrisburg, Pennsylvania, in September.
Each state has developed a State Action Plan.
CARBON SEQUESTRATION - DELAWARE
Delaware hosted a symposium entitled "Carbon Sequestration on Farm and Forest Lands: How to
Make Trading/Offset Programs Work in the Chesapeake Bay Region." The symposium educated
agency staff about carbon sequestration opportunities, identified necessary elements of offset and
trading programs, and analyzed the water quality benefits of agriculturally based carbon offset projects.

-------
CHESAPEAKE ACTION PLAN - EPA AND PARTNERS
The Chesapeake Action Plan (CAP), described in a report to Congress submitted
by the EPA on behalf of the Chesapeake Bay Program in July, will strengthen
and expand partnerships in the watershed, enhance coordination of restoration
activities and improve accountability and transparency in protecting the Bay. The
tools contained in the CAP - the strategic framework, dashboards, detailed activity
database and adaptive management system - will help the Chesapeake Bay
Program become more efficient, strategic, effective and accountable in meeting
its goals.
CONOWINGO DAM/RESERVOIR - PENNSYLVANIA
To better understand the movement of sediments trapped behind Conowingo
Dam on the Susquehanna River, Pennsylvania and the U.S. Geological Survey
are conducting studies of the rate of sediment accumulation. The results will be
available in 2009.
ENGAGING LOCAL GOVERNMENTS - MARYLAND
Through local implementation grants that are part of the Chesapeake and Atlantic
Coastal Bays 2010 Trust Fund, Maryland has provided restoration funding directly
to local communities in the state. To support local implementation, Maryland
developed a new service to connect local governments with resources that help
them accomplish their restoration goals.
ENGAGING LOCAL GOVERNMENTS ON STORMWATER
- WEST VIRGINIA
To learn how to develop communication tools to engage local communities,
two staff members and three stakeholders from West Virginia participated in a
local government training session in July. West Virginia also organized a half-day
stormwater workshop that was attended by 61 local stakeholders, planners
and engineers.
GREEN INFRASTRUCTURE - DISTRICT OF COLUMBIA
To help manage growth and reduce polluted runoff, the District of Columbia
implemented one of the strongest, most innovative stormwater permits in the
nation, launched the RiverSmart Homes program to better manage stormwater
in residential areas, developed an aggressive Anacostia Restoration Plan, and
spent more than $1 million on low-impact development (LID) projects, such as
green roofs.
FARM BILL - CHESAPEAKE BAY COMMISSION
With the passage of the 2008 Farm Bill, the Chesapeake Bay watershed was
singled out to receive an additional $188 million for conservation programs, more
than double the current funding level. Additionally, there is a potential $250 million
for the Chesapeake watershed through national programs in which Bay region
farmers already participate.
FOREST CONSERVATION - U.S. FOREST SERVICE
Most partners that signed the 2007 Forestry Conservation Initiative are on track
to meet their 2012 forest protection goals. The Forest Service hosted a Forest
Conservation Summit in May, bringing together Bay watershed foresters, land
trusts and local governments for the first time. Progress is being made to develop
ecosystem markets such as the Bay Bank and establish a revolving loan fund for
forestland owners who do not want to sell to developers.
LOW-IMPACT DEVELOPMENT - U.S. NAVY
To help reduce polluted runoff to the Chesapeake Bay and its rivers, the U.S. Navy is
evaluating the most effective low-impact development techniques to incorporate into
all large development and redevelopment projects at Navy bases in the Chesapeake
Bay watershed. U.S. Navy personnel are also fostering awareness about low-impact
development on Navy bases.
INNOVATIVE TECHNOLOGY FUND - MARYLAND,
U.S. ENVIRONMENTAL PROTECTION AGENCY
The state of Maryland and the EPA have partnered with the University of Maryland
to develop an innovative program that promotes investment in new research and
technologies that address water quality problems and accelerate Bay restoration.
The EPA has provided funding to the university's Maryland Industrial Partnerships
Program, and the state has partnered with MTECH Ventures to create a seed
capital fund.
RESTORATION FUNDING - U.S. ENVIRONMENTAL
PROTECTION AGENCY
The National Fish and Wildlife Foundation (NFWF) issued a request for pre-proposals
for large-scale restoration projects that use innovative, sustainable and cost-effective
approaches to accelerate the reduction of nutrients and sediments in targeted
Chesapeake Bay sub-watersheds. Funding for these projects comes from the EPA
Chesapeake Bay Program Office.
WETLANDS RESTORATION - NEW YORK
To expand a successful wetlands restoration program in New York, the Upper
Susquehanna Coalition established a 501 (c)(3) wetland trust to supplement grants
and leverage funds, restored 175 acres of non-tidal wetlands designed to maximize
ecosystem functionality, and conducted hands-on training on successful wetland
design criteria.

Pick up after your pet
It's a dirty job, but picking up after your pet makes a big difference in
keeping waterways clean. Pet waste contains nitrogen, phosphorus
and bacteria, which are harmful pollutants. So always pick up after
pets, whether at the park, on a sidewalk or in the backyard.
Volunteer for a watershed group
Watershed groups work to protect the streams, creeks and rivers
that flow to the Bay. These groups perform much of the restoration
work around the region, but they rely on volunteers. To find your local
watershed group, visit www.chesapeakebay.net/findabaygroup.aspx.
Don't fertilize your lawn
We all want a green, healthy lawn. But chemical fertilizers are a major
source of pollution in local streams, rivers and the Bay. When rain
washes fertilizers off thousands of suburban lawns in the region, the
Bay receives too much nitrogen and phosphorus.
