ACKNOWLEDGEMENTS
We would like to gratefully acknowledge all of the federal and state
agencies who financially supported this project - Maryland Department of
Natural Resources, U.S. Army Corps of Engineers - Baltimore District,
Virginia Institute of Marine Science, U.S. Fish and Wildlife Service and the
U.S. Environmental Protection Agency. Effective cooperation by so many
different types of governmental agencies in arranging, during a
comparatively short developmental time frame, a comprehensive survey-mapping
project of this scope is noteworthy. More and more emphasis is being placed
on tracking SAV because of its perceived usefulness as an indicator of
potential and actual improvement in the Chesapeake Bay's water quality and
the correlated balance of living resources.
Acknowledgement would not be complete without high commendation for the
citizens and Maryland charterboat captains who took part in an unusual pilot
program to provide "groundtruthing" of SAV beds to be used in conjunction
with interpretation of the 1985 photography.
The Citizens' Program for the Chesapeake Bay and the Chesapeake Bay
Foundation, together with the U.S. Fish and Wildlife Service, organized
nearly 150 citizens to report locations of grass beds around the Bay.
In addition, about fifteen members of the Maryland Charterboat
Association, funded by Maryland DNR, participated in the ground truthing
program and contributed valuable information on location of grassbeds. The
entire 1985 program, though arranged on relatively short notice, promised
great potential benefits (from both informational and participational
standpoints) that an expanded 1986 ground truthing program was organized.

ABSTRACT
In 1985, color aerial photography at a scale of 1:12,000 was used to
map SAV in the Maryland section of the Chesapeake Bay, while black and white
photography at a scale of 1:24,000 was used to map the Virginia section.
Both areas had been photographed with 1:24,000 color photography in 1984.
SAV beds detected on the aerial photography were traced onto mylar USGS
topographic quadrangles, and areas of each bed were then digitized. Data
were reported in square meters for each quadrangle. Ground information was
available from USGS, Md.DNR, University of Maryland, Horn Point Laboratory,
Harford Community College and VIMS. Citizen support via the Chesapeake Bay
Foundation and Citizens Program for the Chesapeake Bay as well as Maryland's
Charterboat Association via Maryland's DNR Watermen's Assistance PRogram
provided additional ground support.
A total of 19,390 hectares of SAV was mapped in 1985, a 26% increase
over that reported in 1984 (15,400 hectares). The Upper Bay zone had 3,025
hectares, a decrease of 4.5% (15.6% of the total SAV in the bay) from that
reported in 1984. Sixty-six percent of the vegetation was located on the
Susquehanna Flats. The Middle Bay zone had 4986 hectares of SAV (25.7% of
the total SAV in the bay), which represents a 389% increase from that
reported in 1984). Most of this increase was reported from Eastern Bay,
Choptank River and the Middle Eastern Shore section. SAV beds in those
areas of the main stem bay that showed the greatest increase consisted
primarily of Ruppia maritima. The Upper Potomac River section continued to
show improvement in SAV abundance with 1440 hectares in 1985. Although
Hvdrilla verticillata is the dominant species, fourteen other species
coexist with H. verticillata. The Lower Bay zone had 11,379 hectares (58.7%
ix
-------
of the total SAV in the bay), an amount similar to that reported in 1984.
Sixty-eight percent of the SAV in this zone is found along the bayside of
the eastern shore, principally between Tangier and Smith Islands and the
mouths of Cherrystone Inlet, Hungars Creek, Mattawoman Creek, Pungoteague
Creek, Craddock Creek and Chesconessex Creek. Western shore SAV beds are
concentrated at the mouth of York River, Plum Tree Island, Back River and
along the shoreline of the Mobjack Bay.

SECTION 1
INTRODUCTION
Communities of submerged aquatic vegetation (SAV) are an integral part
of the Chesapeake Bay ecosystem. They provide an important habitat for many
species which use SAV either as a food source or as protection from
predators, e.g., a nursery. They reduce currents and baffle waves, allowing
for deposition of suspended material and enhanced water clarity. In
addition, they bind sediments with their roots and rhizomes to prevent
erosion of the underlying material. They are important in nutrient cycling
both through the absorption and release of nitrogen and phosphorus (Thayer
et al.t 1975; Kemp et al., 1984; Orth et al., 1984; Ward et a!., 1984).
The interest in SAV communities generated in the 1970's because of
their dramatic baywide decline has continued to the 1980's. A key aspect of
the research programs recently being funded in both Maryland and Virginia
entails an annual monitoring of all SAV beds in the Chesapeake Bay and its
tributaries.
The first baywide aerial survey of SAV beds was conducted in 1978 and
resulted in two separate reports for the SAV distribution in Virginia and
Maryland (Orth et al., 1979; Anderson and Macomber, 1980). Between 1979 and
1984, a number of field and aerial surveys were conducted by various state
agencies in sections of the bay, but there was no single attempt to conduct
or coordinate a baywide effort to monitor the SAV distribution.
The first coordinated effort to map all the SAV beds in the bay was
attempted in 1984. In addition to the aerial surveys, any ground survey
information available for 1984 was included to provide as detailed a picture
as possible of the distribution of SAV that year (Orth et al., 1985).
-------
Although some problems were experienced in acquiring the photography (poor
weather, airspace restrictions, etc.), almost all areas were covered with
photography. Ground surveys included efforts by the U.S. Geological Survey
(USGS) and the Northern Virginia Community College (NVCC) in the Potomac
River, Maryland's Department of Natural Resources (DNR) SAV station survey
of the entire upper bay, the Virginia Institute of Marine Science (VIMS)
surveys in the lower bay, and several sectional surveys conducted by Harford
Community College (HCC) and the University of Maryland's Horn Point
Laboratory (HPL).
A coordinated aerial photographic survey for SAV adjacent to the
shoreline of the Chesapeake Bay and its tributaries was repeated in 1985.
Ground survey information was available from USGS, DNR, HPL, HCC and VIMS.
In addition to these scientific surveys, the Chesapeake Bay Foundation (CBF)
and the Citizens Program for the Chesapeake Bay (CPCB) solicited help from
citizen volunteers to help locate SAV beds and provide ground truth for the
aerial photography. Maryland's Charterboat Association also participated in
the SAV ground truthing through funding provided by Maryland's DNR
Watermen's Assistance Program.
This final report again represents a unique effort to combine all the
SAV information for 1985 into one cohesive baywide product.

SECTION 2
SAV SPECIES
Ten species of submerged aquatic vegetation are commonly found in the
Chesapeake Bay and its tributaries. Zostera marina (eelgrass) is dominant
in the lower reaches of the bay. Mvriophvllum spicatum (water milfoil),
Potamogeton pectinatus (sago pondweed), P. perfoliatus (redhead grass),
Zannichelia palustris (horned pondweed), Vallisneria americana (wild
celery), El odea canadensis (common el odea), Ceratophvllum demersum
(coontail) and Na.ias quadalupensis (southern naiad) are less tolerant of
high salinities and are found in the middle and upper reaches of the bay
(Stevenson and Confer, 1978; Orth et al., 1979; Orth and Moore, 1981, 1983).
Ruppia maritima (widgeongrass) is tolerant of a wide range of salinities and
is found from the bay mouth to the Susquehanna Flats. Approximately ten
other species are found less commonly and are present primarily in the
middle and upper reaches of the bay and the rivers (Appendix A). One
species presently found in the Potomac River and Susquehanna Flats, Hvdrilla
verticillata (hydrilla), has the potential for becoming one of the dominant
species found there (Orth and Moore, 1984; Allaire et al., 1985; Rybicki et
al., 1985). Data in this report confirm the rapid spread of H. verticillata
in the Potomac River.

SECTION 3
METHODS
Aerial Photography
Aerial photography was the principal method used to assess the
distribution of SAV in the Chesapeake Bay and its tributaries in the 1985
study. Predetermined flight lines for photographing areas that either had
SAV or could potentially have SAV (i.e., all areas where water depths were
less than 2 m at mean low water) were drawn on 1:250,000 scale USGS maps to
ensure both complete coverage of SAV beds and inclusion of land features as
control points for mapping accuracy (Figs. 1 and 2). The large number of
flight lines in Maryland compared to Virginia corresponded to the different
scale at which the photography was flown in the upper bay. In addition,
additional flight lines were added in Maryland for emergent wetlands
mapping. Some areas in Virginia were not included because of the known lack
of SAV in those areas. All the shoreline areas in Maryland were
photographed in 1985.
The general guidelines used for mission planning and execution are
given in Table 1. These guidelines, which address tidal stage, plant
growth, sun elevation, water and atmospheric transparency, turbidity, wind,
sensor operation and plotting, allowed for acquisition of photographs under
near-optimal conditions. The guidelines are critical because significant
distortion of any one item could significantly decrease the ability to
detect the SAV or to interpret the photography properly as to the presence
or absence of SAV.

TABLE 1. GUIDELINES FOLLOWED DURING ACQUISITION OF AERIAL PHOTOGRAPHS.
1. Tidal Stage - Photography was acquired at low tide, +/- 0-1.5 ft., as
predicted by the National Ocean Survey tables.
2. Plant Growth - Imagery was acquired when growth stages ensured maximum
delineation of SAV, and when phenologic stage overlap was greatest.
3. Sun Angle - Photography was acquired when surface reflection from sun
glint did not cover more than 30 percent of frame. Sun angle was
generally between 20p and 40p to minimize water surface glitter. At
least 60 percent line overlap and 20 percent side lap was used to
minimize image degradation due to sun glint.
4. Turbidity - Photography was acquired when clarity of water ensured
complete delineation of grass beds. This was visually determined from
the airplane to insure that SAV could be seen by the observer.
5. Wind - Photography was acquired during periods of no or low wind. Off-
shore winds were preferred over on-shore winds when wind conditions
could not be avoided.
6. Atmospherics - Photography was acquired during periods of no or low haze
and/or clouds below aircraft. There could be no more than scattered or
thin broken clouds, or thin overcast above aircraft, to ensure maximum
SAV to bottom contrast.
7. Sensor Operation - Photography was acquired in the vertical mode with
less than 5 degrees tilt. Seale/altitude/fi1m/focal length combination
permitted resolution and identification of one square meter area of SAV
(surface).
8. Plotting - Each flight line included sufficient identifiable land area
to assure accurate plotting of grass beds.
-------
The acquisition of aerial photography for SAV in Virginia was
contracted to Air Photographies, Inc. by the Bionetics Corporation, the
on-site contractor to the U.S. EPA Environmental Photographic Interprative
Complex (EPA-EPIC). The camera used was a Wild RC 10 cartographic camera
with a 152 mm (6 inch) focal length Aviogon lens. Film used was Kodak 24 cm
(9 1/2 inch) square negative Double X Aerographic type 2405. The camera was
mounted in a camera port in the bottom fuselage of Air Photographies, twin
engine, fixed low wing Piper Aztec aircraft. A Wratten 1A haze filter was
used inside the cone of the camera to reduce the degrading effect of
atmospheric haze on image quality. Flights were conducted at an altitude of
approximately 12,000 ft, yielding a scale of 1:24,000 for the photograph,
approximating that of a standard USGS topographic quadrangle.
The SAV photography for the Maryland waters was obtained by Aero Eco
under contract to the Bionetics Corporation (onsite contractor for
EPA/EPIC). The camera used by Aero Eco was a Zeiss Jena LMK 15/2323 with a
153 mm (6 inch) focal length Zeiss Jena Lamegon PI/C lens. The film used
was Kodak 24 cm (9 1/2 inch) squarepositive Aerochrome MS type 2448. The
camera was mounted in the bottom fuselage of Aero Eco's Partenavia P68
Observer, a twin engine high wing reconnaissance aircraft. The photography
was acquired at an approximate altitude of 6,000 feet, yielding a
photographic scale of 1:12,000.
The only problem encountered during the acquisition of the 1985 aerial
photography was getting permission to fly in the restricted airspace over
Aberdeen Proving Ground. The delays caused acquisition to be pushed back to
October 27, which was too late to get the SAV at its peak biomass, although
much SAV was still visible.
-------
Mapping Process
Fig. 3 gives the location of the topographic quadrangles in the study
area. This area includes all regions with a potential for SAV growth. The
quadrangles are sequentially numbered to allow for more efficient access to
the data. Table 2 gives the corresponding names of the 157 quadrangles
shown in Fig. 3.
SAV beds were identified on the photographs using all available
Information, including knowledge of aquatic grass signatures on the film,
areas of grass coverage from previous flights, ground information, and
aerial visual surveys. Mylar topographic quadrangles (1:24,000 for
Virginia, 1:12,000 for Maryland) were used as base maps in the mapping
process. Delineation of SAV bed boundaries was facilitated by superimposing
on a light table the appropriate mylar quadrangle with the transparent
photograph. SAV boundaries were delineated on the mylar map with a pencil.
Where minor scale differences were evident between the photograph and
quadrangle or where significant shoreline erosion or accretion had occurred
since production of the map, a best fit was obtained, or shoreline changes
were noted on the quadrangle. Areas of SAV beds were derived from the
topographic quadrangles. VIMS measurements were made on a Numonics Graphics
Calculator, model 1224 for the lower bay, while EPIC utilized a Calma
Graphic Interactive Image Analysis System based on a Data General Eclipse
S230 minicomputer for upper bay areas. Each SAV bed was digitized three
times and the area reported as the average of the three. Each of the three
measurements was generally within 5% of the mean.
In addition to the boundaries of the SAV bed, an estimate of percent
cover within each bed was made visually in comparison with an enlarged Crown

Density Scale, similar to those developed for estimating of forest tree
crown cover from aerial photography (Fig. 4). Bed density was classified
into one of four categories based on a subjective comparison with the
density scale. These were: 1. very sparse, <10%, 2. sparse, 10 to 40%; 3.
moderate, 40 to 70%; or 4. dense, 70-100%. Either the entire bed, or sub-
sections within the bed, were assigned a number (1 to 4) corresponding to
the above density categories. In addition to the density scale, each
distinct SAV unit was given a letter designation for proper identification
for future comparisons.
In order to reduce interobserver variability in both the mapping and
digitizing processes, steps were taken to ensure quality assurance.
Sections from several areas in both Maryland and Virginia containing SAV
were independently mapped and assigned a density classification. Results
were compared for compatibility of the mapping effort. In addition, mapped
sections were independently digitized for similar comparisons.
The discussion of the distribution of SAV has been organized into three
zones as established by Orth and Moore (1982). The area between the mouth
of the bay to a line stretching from the mouth of the Potomac River at Smith
Point in Virginia to just above Smith Island and extending across to the
north shore at the mouth of the Big Annemessex River is referred to as the
Lower Bay zone (Fig. 5). The area between the north shore of the Big
Annemessex River and the south shore of the Potomac River to the Chesapeake
Bay bridge at Kent Island is referred to as the Middle Bay zone. The area
between the Chesapeake Bay bridge and the Susquehanna Flats is referred to
as the Upper Bay zone. The salinity within each zone roughly coincides
with the major salinity zones of estuaries: polyhaline (18-25°/oo), Lower
zone; mesohaline (5-18°/oo), Middle zone; oligohaline (0.5-5°/oo), Upper

zone. Although the major rivers and smaller tributaries of the bay have
their own salinity regimes, the distributions of SAV in each river are
discussed within the zone where it connects to the bay proper.
In addition, 21 major sections of the bay are identified for more
detailed discussion of SAV distribution (Fig. 5, Table 3). These sections
denote relatively distinct parts of the bay that are readily identifiable
from a map. Sections 1 through 4 are located in the Upper Bay zone.
Sections 5 through 12 are located in the Middle Bay zone, and sections 13
through 21 are located in the Lower Bay zone.
Orth et al. (1979) chose six sites in the Lower Bay zone to determine
changes in SAV distribution starting in 1937. These sites are: Mumfort
Island and Jenkins Neck in the York River; East River in the Mobjack Bay;
Parrott Island in the Rappahannock River; Fleets Bay located between
Windmill Point on the Rappahannock River and Smith Point on the Potomac
River; and Vaucluse Shores, located on the bayside of the eastern shore just
above Cape Charles (see Orth et al. (1979) for further details of these
historical sites). Detailed mapping of each historical site was completed
in this study similar to the earlier work to provide a 1985 update.
Ground Truth and Other Data Bases
For those areas in Virginia where aerial photographic evidence of SAV
beds was inconclusive, photoverification was accomplished by ground truthing
these sites. This was done principally by small boats and divers snorkel ing
over the area indicated from the photograph. Since SAV beds in this region
contain primarily only one or two species that vary little from year to
year, a great deal of ground truth information could be extrapolated from

earlier studies (Orth et al., 1979, 1982; Orth and Moore, 1982). In
addition, VIMS is currently transplanting SAV (principally eelgrass) into
different river systems. These areas are checked carefully for any SAV when
transplant sites are examined by divers.
In Maryland, ground truth data were provided principally from two SAV
surveys conducted in 1985, from an SAV transplanting project and an ongoing
SAV research project. One field survey was conducted in the Potomac River.
This survey was conducted by the USGS (Rybicki et al., 1986) and included
the area from the Chain Bridge at Washington, D.C. to Quantico, Virginia
(Fig. 6). Earlier surveys of the Potomac River by the USGS included
sections of the river south of Quantico to the mouth of the Potomac River
(Haramis and Carter, 1983; Carter et al., 1985a,b; Rybicki et al., 1985).
The 1985 USGS objectives were: 1. to collect and identify all species of
SAV found in the tidal river and larger tributaries, 2. to determine the
distribution and abundance of SAV using shoreline surveys and transects, 3.
to compare 1985 data on species composition, standing crop and water quality
with previous USGS surveys, and 4. to monitor the spread of H- verticillata
and to collect data on competition between H. verticillata and other SAV.
The shoreline survey was conducted in September and October, 1985, by
boat, using rakes to collect samples for the presence or absence of SAV.
In addition, sixty-two transects were sampled in June and again in
September. Transects had sampling stations at 5m, 15 m and then at 15 m
intervals perpendicular to shore. Transects were terminated at five
stations (60 m) from shore when no SAV was present or at two stations (30 m)
beyond the last vegetated station. Where water depth exceeded 2.0 m at 60 m
of linear distance, the fixed interval was not used, and samples were taken

at four stations along the transect corresponding with the depths of 0.5,
1.0, 1.5 and 2.0 m.
Codes for the transects in Fig. 6 provide information on location and
the river - or tributary mile for each location. For example, in MN-01T-2,
MN is Mattawoman Creek, 01T is one nmi (nautical mile) up the tributary from
the mouth, -2 is the second transect; in PY-06R, PY is Piscataway Creek, 06R
is the sixth transect on the edge of the main river.
All stations were sampled three times using modified oyster tongs. The
area sampled with each grab was 930 cmr. All species were identified.
Samples were dried and standing crop expressed in g/sample and g/mr for each
species. By fall, in many areas, the plants formed a tangled mass
o
completely filling the water column; a grab area of 930 cm resulted in a
sample from a significantly larger area. For this reason, station dry
weight (total dry weight of three grabs) greater than 100 g cannot be
directly related to area and therefore was not calculated.
The third survey is the annual large scale multi-station survey
conducted by the Md.DNR. This survey, conducted from July through August,
samples 600+ randomly selected stations in certain areas of the bay from the
Susquehanna Flats to Smith Island. At each station, samples are also
collected with modified oyster tongs and species presence or absence, as
well as standing crop, is recorded. Station locations were randomly
generated and were limited to areas 2.4 m (8 ft) or less in depth on the
western shore of the bay and 3.7 m (12 ft) or less on the eastern shore.
The SAV transplanting project is being conducted on the Susquehanna
Flats by Stan Kollar of HCC. Information provided by his work is in the
form of species presence by percentage, primarily by visual estimates.
21
-------
A SAV research group at HPL headed by Court Stevenson also provided
ground truth data. Maps of their study sites on the Choptank River were
annotated on the maps for this report indicating the status of SAV for 1985.
In addition to the scientific surveys, private citizens participated in
identifying SAV beds by checking areas in the bay for SAV. Two groups were
responsible for looking for SAV under the sponsorship of separate
organizations.
The Maryland Charterboat Association participated in the baywide
effort, funded by the Md.DNR's Watermen's Assistance Program. Boat captains
were provided with reduced SAV quadrangle maps and data sheets for each SAV
bed identified on the maps. Sampling of sites with SAV were undertaken at
low tide. Samples were taken by hand, net or rake. Plants were identified
as to species onsite or placed in zip-lock plastic bags and sent to the DNR
for identification.
Private citizens volunteered to assist in the SAV ground survey under
guidance of the CBF, CPCB and F&WS. This program entailed identifying and
recording the location of SAV in the bay. Volunteers were recruited through
press releases, newsletters and personal letters. Volunteers, provided with
an identification guide of SAV and maps of their area of interest, visited
numerous sites around the bay. Each volunteer was asked to identify the
location where SAV was sighted, as well as water conditions, how many and
which kind of species, grassbed size, percentage area covered, and location
description. All information was sent to EPIC for data storage.
All ground survey information was included on the topographic
quadrangles to show positions of the survey stations in relation to the beds
of SAV mapped from the aerial photographs. Each survey was designated by a
unique symbol to eliminate confusion of the different methods. Where
22
-------
species information was available, it was included on the map unless there
was too much data or it was redundant.
Data Presentation
SAV distribution data were analyzed by topographic quadrangle (Table
4), by section and zone (Table 5) and by quadrangles within a section (Table
6). Data for 1978 and 1984 by quadrangle, section and zone were included in
Tables 5 for comparison. In addition, all the Md.DNR data for each river
system from the first annual survey conducted in 1971 are included (Table
7).

RESULTS
1. SUSQUEHANNA FLATS
The distribution of SAV in this section decreased by 6.5% in 1985, from
2150 hectares in 1984 to 2011 hectares in 1985 (Tables 4-6). Mapping of SAV
in this section was accomplished both by the use of aerial photography and
information provided by Stan Kollar, HCC, where the SAV was too sparse to be
detected from the aerial photos. Seven species of SAV were found in 1985
with M. spicatum the most abundant. Other species of importance which
appear to be increasing in abundance along the Susquehanna River and in the
Havre de Grace area were H. dubia. V. americana. H. verticillata.
The Md.DNR survey found SAV (M. soicatum) at one of the 37 stations
they sample annually in the Susquehanna Flats (Table 7). No stations are
located in the Susquehanna River, where SAV occurs as far north as Robert
Island.
2. UPPER EASTERN SHORE
This section showed a 142% increase in SAV from 1984 to 1985. A total
of 104 hectares were mapped in 1985 as compared to 43 in 1984 (Tables 4-6).
Most of the increase in SAV in 1985 occurred along the Elk, Bohemia and
Sassafras Rivers. Of the 7 quadrangles mapped in this section, only Galena
showed a decrease in SAV. Fifteen stations were sampled by the Md.DNR in
the Elk and Bohemia Rivers, with no vegetation recorded at any of the
stations (Table 7). Similarly, no vegetation was found at the 10 stations
sampled by the Md.DNR survey on the Sassafras River or the 5 stations on
37
-------
Stillpond Creek. Other field surveys conducted by citizens and charterboat
captains and SAV drift observed by Md.DNR field crews indicate that M.
spicatum is the most prevalent species in this section. Seven stations
sampled by Md.DNR in the southern portion of the section from Howell to Swan
Points also had no SAV.
3. UPPER WESTERN SHORE
The 1985 aerial survey indicated there were 238 hectares of SAV, a
decrease of 2.4% from that estimated in 1984 (Tables 4-6). Aerial coverage
of this section was complete in 1985, thus the estimated 1984 coverage may
have been fairly accurate, since little increase or decrease was generally
seen on the Western Shore in 1985. Aerial photos indicated that SAV was
present in all river systems (Gunpowder, Bush, Back, Middle and Magothy) in
the section. Generally, most of the SAV was present along the lower
sections of these rivers.
A total of 4 of 27 Md.DNR stations on the Gunpowder, Bush, Back and
Middle Rivers had rooted SAV in 1985, an increase of 1 station over 1984
(Table 7). Species present in these samples were M. spicatum. Chara sp., V.
americana. P. perfoliatus. and N. quadilupensis. No rooted SAV was found by
Md.DNR at the 12 Magothy River stations.
4. CHESTER RIVER
In 1985, 671 hectares of SAV were mapped in the Chester River Section,
a decrease of 8.2% from the 731 hectares mapped in 1984 (Tables 4-6).
Again, most of the SAV mapped (87%) occurred on the Langford Creek
38
-------
quadrangle. In all, 8 of the 9 quandrangles in the section had SAV present
in 1985. Five species of SAV were reported by citizen and Md.DNR field
surveys. These species were R. maritima. P. pectinatus. P. perfoliatus. Z.
palustris and M. spicatum. with P. perfoliatus and JR. maritima reported most
often. Aerial coverge of this area was complete in 1985.
The Md.DNR Survey found 8 (22.2%) of their 35 stations in the Chester
River vegetated in 1985, as compared to 7 (19.4%) in 1984 (Table 7).
5. CENTRAL WESTERN SHORE
A total of 26.3 hectares of SAV was mapped in this section in 1985,
while none was seen in 1984 (Tables 4-6). Seventy-two percent of the SAV
reported was located in Herring Bay on the North Beach quadrangle. No SAV
was mapped in any of the river systems in this section except for a small
bed near the mouth of the West River.
The Md.DNR survey found no rooted SAV in the Severn, South, West and
Rhode River sections (Table 7).
6. EASTERN BAY
In 1985, 356 hectares of SAV were noted on the aerial photography, an
increase of 441% over the 66 hectares reported in 1984 (Tables 4-6). R.
maritima was the most abundant species reported in field surveys by citizens
and Md.DNR personnel. P. pectinatus and P. perfoliatus were also reported,
but other species reported in 1978, such as M. spicatum. E. canadensis. and
Z. palustris were not seen.
39
-------
The Md.DNR survey, as in 1984, found no SAV at the stations from Love
Point to Kent Point, while an increase of 3 (6.5%) to 8 (17.4%) of 46
stations in Eastern Bay were vegetated (Table 7). R. maritima was the only
species found in the survey.
7. CHOPTANK RIVER
In 1985, 1528 hectares of SAV were noted on the aerial photography, as
compared to 82 hectares seen in 1984 (Tables 4-6). This represents a 1760%
increase over the previous year. Ten of the 13 quadrangles in the section
had SAV in 1985, compared to only 6 in 1984, and 6 had over 100 hectares of
SAV. A total of 6 species were reported to occur in this section. R.
maritima was by far the most abundant species reported in field surveys.
Other species found were P. perfoliatus. P. pectinatus. £. palustris. N.
ouadilupensis. and V_. americana.
The Md.DNR survey found rooted SAV at 7 of 60 stations on the Choptank
River in 1985 (Table 7), while none of the 19 stations on the Little
Choptank River had SAV. All SAV found was R. maritima.
Studies by the University of Maryland Center for Environmental and
Etuarine Studies at the Horn Point Laboratory (HPL) also confirmed the
increases in SAV seen on the aerial photography. Dr. Court Stevenson, who
coordinates the SAV research at the HPL, reported that there was a strong
resurgence of SAV in the lower Choptank River, with Z. oalustris seedlings
evident at many sites in May, while R. maritima replaced it was the dominant
species in July. Plants were found in areas where no grass had existed for
the past five years. The main study site at Chapel Creek had dense stands
of SAV in 1985 where only vestigial populations existed in 1984. Visual
40
-------
reconaissance during low level aerial flights indicated that SAV was present
mostly in protected coves of the lower Choptank River. No grass was sighted
above the Cambridge Bridge. Although a resurgence in R. maritima was seen
in 1985, other species such as P. perfoliatus. P. pectinatus and M.
spicatum. once common in the Choptank River, were not observed (Stevenson et
al., 1986).
The UMd.HPL is also conducting SAV transplant studies in the Choptank
River. Their six study sites (Horn Point, Chapel Creek, Todd's Cove, Boone
Creek, Foxhole Creek, Irish Creek) are all located along the lower Choptank
River. All the selected sites had SAV in the 1970's, which had declined
substantially in the 1980's.
Because of the relatively low runoff associated with the dry spring and
summer of 1985, salinities were much higher (12-17 ppt) (Table 8) than
normal (they can be as low as 8 ppt in wet summers). Because of this, R.
maritima (a species with high salinity tolerance) was able to colonize a
wide range of habitats. Mean dissolved nitrogen levels are just under 10 uM
(Table 8) while dissolved inorganic phosphorus was well under 1.0 uM (Table
8). High turbidity, which has been implicated as one the major reasons for
the SAV decline, is somewhat reflected by the seston values (Table 8). In
relation to this, average light measurements of the study sites (Table 8)
show a wide fluctuation, which most likely impacts the potential for
reestablishment of SAV at sites such as Todd's Cove (Stevenson, et. al.,
1986). In support of this reasoning, the study site with the lowest mean
seston and lowest mean light attentation values (Irish Creek) had the
greatest amount of SAV (69.8 ha) mapped from the aerial photography.

8. PATUXENT RIVER
In 1985, 44 hectares of SAV were noted on the aerial photography, as
compared to only 9 in 1984 (Tables 4-6). SAV was noted on 4 of the 5
quadrangles in this section.
The Md.DNR survey found no SAV at the 43 stations they surveyed (Table
7).
9. MIDDLE WESTERN SHORE
A total of 23 hectares of SAV was noted on the aerial photography in
this section in 1985 (Tables 4-6). Ninety-nine percent of their SAV
occurred in areas where aerial photography was not available in 1984. Four
of the eight quadrangles in this section had vegetation, with 71% of it
occurring on the Point No Point quadrangle. Most of the mapped SAV in this
section occurred in small marsh ponds that drain into the bay. The Md.DNR
survey found no SAV at 8 sampled stations from Curtis to Cove Points (Table
7). This section is a very exposed region, with little habitat suitable for
SAV; thus it would not be expected to support significant stands of SAV.
10. LOWER POTOMAC RIVER
In 1985 there were 381 hectares of SAV in the Lower Potomac River, as
compared to 194 mapped in 1984 (Tables 4-6). This represents a 69%
increase, of which 9% is accounted for by quadrangles that were not mapped
in 1984 because of a lack of photographic coverage. Only 9 of the 20
quadrangles in the section had SAV, and 2 that had SAV in 1984 (Colonial
43
-------
Beach South and Stratford Hall) had none in 1985. Seventy-four percent of
the SAV mapped in 1985 occurred on the Mathias Point quadrangle.
The Md.DNR survey sampled 88 stations in the lower section, and found
vegetation at 4 stations, all at the very northern end of the section near
Upper Cedar Point, and in the Nanjemoy River. Species located at these
stations were £. perfoliatus. V. americana. 1. palustris. M. soicatum and N.
quadiluoensis.
11. UPPER POTOMAC RIVER
Once again in 1985 the Upper Potomac River exhibited a significant
increase in abundance of SAV (Tables 4-6). In 1985, 1440 hectares of SAV
were noted on the aerial photography as compared to 600 in 1984. This
represents a 140% increase. The vegetation is still largely confined to the
upper reaches of the section between Alexandria, Virginia and Marshall Hall,
Maryland (Figure 6). Ninety-five percent of the mapped SAV occurred on the
Alexandria and Mount Vernon quadrangles, which cover the upper reaches
previously described. Ten species were found in this reach during the USGS
monitoring program in which 62 transects were sampled in spring and fall and
a shoreline survey is made in fall. Tables 9, 10, and 11 present data for
macrophyte species found on individual vegetated transects, the relative
occurrence of vegetated transects, stations and grabs, and total sampled dry
weight and biomass of all species of SAV for the spring and fall,
respectively.
In 1985, USGS estimated that areal coverage of SAV in their study area
was approximately 3600 acres, based on shoreline survey information and
aerial photographs. The aerial mapping effort for the same area, calculated

3557 acres of SAV which, without the benefit of a ground truth survey, is
only 1.2% different than the USGS estimate. Since 1984, the vegetation has
spread almost 2 kilometers further downriver. Almost all areas less than 2
meters deep were vegetated with SAV. The most abundant and most widely
occurring species were H. verticillata. M. spicatum. H. dubia. C. demersum.
V. americana and N. quadiluoensis. H. verticillata. M. soicatum and C.
demersum occurred in 79%, 55% and 47% of the vegetated transect samples in
the fall of 1985 (Figure 7). H. verticillata dominated Hunting Creek, Swan
Creek and the Dyke Marsh area (Figure 8). Results of the USGS shoreline
survey show that H. verticillata was more abundant than all other species in
25% of the vegetated areas, accounting for 62% of the total fall dry weight.
As mean secchi disk readings above Marshall Hall (87 cm ± 31) were
significantly better than below Marshall Hall (55 cm ± 19), poor light
penetration may partially account for the lack of vegetation below Marshall
Hall in this section. Other factors may also be involved because light
measurements with an underwater spectroradiometer in 1985 suggest that
sufficient light reaches the bottom for plant growth in less than 1.5 meters
of water.
The Md.DNR survey sampled 52 stations in this section, with a total of
3 stations yielding SAV. Rooted SAV species found at these stations were
M. SBicatum. H. verticillata and C. demersum.
12. MIDDLE EASTERN SHORE
In 1985, there was 1188 hectares of SAV in this section, as compared to
only 33 hectares in 1984 (Tables 4-6).. This represents a 3504% increase,
the largest increase seen in any section of the bay. Twelve of the fifteen

quadrangles in the section had vegetation in 1985, while only 5 had
vegetation in 1984. One of the most significant increases was the 265
hectares, mostly occurring in one large bed, in the Barren Island Gap
region, where no SAV was seen in 1984.
The Md.DNR survey sampled 169 stations in this section examining sites
in the James-Barren Island system, Honga River, Fishing Bay, Barren
Island/South Marsh Island, Nanticoke-Wicomico River, Manokin River and Big
Annemessex River (Table 7). SAV was found at one station each in the James-
Barren Island system, Honga and Bloodsworth Island/South Marsh Island
sections, while 2 stations in the Manokin River, and 3 stations in the
Big/Little Annemessex River sections had SAV. No SAV was found in the other
sections sampled by the Md.DNR survey. R. maritima was found at 7 of the 8
sample points with SAV, while £. oalustris was located at the other site.
13. TANGIER ISLAND COMPLEX
This section contains the greatest amount of SAV in the Lower Bay zone
(5,504 ha or 49% of the total for this zone) and is similar to the amount
reported for 1984 (5447 ha).
SAV beds are concentrated in distinct areas in the section: adjacent
to Big Marsh between Chesconessex Creek and Deep Creek, on the west side of
Webb and Halfmoon Island, on the east side of Great Fox Island and in the
areas between Tangier and Smith Island. Dominant species in this section
are Z. marina and R. maritima. Although this section has significant stands
of SAV, and data indicates that SAV has been increasing in abundance here,
the MD.DNR survey found SAV in only 8 of 57 stations in this section (Table
7). The DNR survey indicated that SAV abundance decreased to 23.5% of the
52
-------
surveyed stations in the Smith Island portion and has been continually
declining from 47.1% of the stations in 1980, contrary to the findings of
the aerial survey. An examination of the 57 stations visited by DNR
scientists indicated most stations were in waters too deep or occurred just
outside SAV beds delineated from aerial photographs. Where survey stations
Indicated presence of SAV, six of the eight stations occurred in SAV beds
mapped from aerial photographs.
Observations from citizens indicated SAV in 3 of the 6 mapped SAV beds,
with 2. marina being observed at 5 of the 6 stations.
14. LOWER EASTERN SHORE
This section contained 20% of the SAV in the Lower Bay zone with 2,227
hectares present in dense to scattered, patchy beds from Chesconessex Creek
to Elliotts Creek (Tables 4-6). Large beds of I. marina and R. maritima
were present around Cape Charles, and at the mouths of Cherrystone Inlet,
Hungars Creek, Mattawoman Creek, Occahannock Creek, Craddock Creek,
Pungoteague Creek and Onancock Creek. The areas between these creek systems
are sparsely vegetated or unvegetated because of the exposed and dynamic
nature of these broad flats.
SAV in the Vaucluse Shore historical area was reduced slightly (6%)
from 1984 (Table 12). The SAV at the site has been gradually declining in
the last 50 years principally due to the migrating nature of the sand bars
and spits which cover existing SAV and eliminate the area from potential SAV
growth.

15. REEDVILLE
The Reedville section (Tables 4-6) contained 172 hectares in 1985, a
reduction of 35% from 1984. This reduction was also evident in the Fleets
Bay historical area which declined in areal coverage by 15% (Table 12).
Most of the SAV beds in this section are small and sparse, they are
susceptible to disturbance and can undergo rapid changes in short periods of
time. Much of the decline observed between 1984 and 1985 occurred in the
patchy beds designated with a density class of 1.
16. RAPPAHANNOCK RIVER COMPLEX
Only 20 hectares of SAV were found in this section in 1985, similar to
the total area found in 1984 (Tables 4-6). The SAV stands found in the
Milford Haven area, consisting of Z. marina and R. maritima. are still
present and very dense. Direct observations indicate the persistence and
the very healthy nature of these beds. There were no SAV beds in the
Parrott Island historical area (Table 12). Transplanting of Z. marina near
Parrott Island has not been successful, while some of the transplanted Z.
marina in the Piankatank River off Burton's Point in 1984 has survived and
is still present in the summer of 1986. The patches of transplanted grass
o
are very small (
-------
17. NEW POINT COMFORT REGION
SAV beds in this section are concentrated in the area between New Point
Comfort Lighthouse and Horn Harbor (Tables 4-6). This section contained 332
hectares of SAV, consisting of £. marina and R. maritima. and represents on
11% increase in areal coverage from 1984.
18. MOBJACK BAY COMPLEX
This section contains the greatest amount of SAV along the entire
western shore with 1505 hectares present in 1985 (Tables 4-6). This is a 3%
decrease from 1984. SAV beds, consisting of !• marina and R. maritima. are
present along the shorelines of the entire Mobjack Bay and three of four
tributaries: the Severn, Ware and North Rivers. Little SAV is found in the
East River.
SAV in the East River historical area decreased 32% from 1984 (Table
12).
19. YORK RIVER
This section contained 258 hectares of SAV in 1958 (Tables 4-6) an
increase of 8% over that found in 1984. SAV beds (Z. marina and R.
maritima) are present from Gloucester Point to the mouth of the river and
are principally found along the north shore. No SAV beds are found above
Gloucester Point, although a number of previously vegetated sites have been
used for transplant experiments by VIMS scientists. Transplanted SAV beds
57
-------
(Z. marina only) at Gloucester Point are thriving and individual planted
units are rapidly expanding. The bed planted in 1982 on 1.0 and 0.5 m
centers is now one cohesive unit while individual units planted on 2.0 m
centers in 1983 in an area adjacent to the 1982 plantings are growing.
Individual sods, 225 cmr, have now increased in areal coverage to 11,000 cmr
in less than 3 years. The patches are more elliptical in shape, with the
long axis occurring parallel to the beach. These patches average 131 by 106
cm. Success rate with transplanted Z. marina at Mumfort Island has been
much less than at the Gloucester Point area. Z. marina transplanted to Clay
Bank, the previous upriver limits of the species, in the past, never
survived through the summer.
SAV in the Jenkins Neck historical area increased 17% from 1984, but is
still 150 ha below levels found during the years when SAV was very abundant
(Table 12). SAV continues to be absent from the Mumfort Island historical
area (Table 12).
20. LOWER WESTERN SHORE
There were 1315 hectares of SAV in this section in 1985 (Tables 4-6),
an increase of 14% from 1984. These beds, consisting of both Z. marina and
R. maritima, are still concentrated in Broad Bay, Back River, Drum Island
Flats adjacent to Plumtree Island and on the south side of Goodwin Island.
The beds found on Drum Island Flats represent one of the more extensive and
densely vegetated areas along the western shore today.
58
-------
21. JAMES RIVER
There are no SAV beds in the James River that have been identified from
the aerial photography or ground surveys (Tables 4-6). Many of the
tributaries of the James River most likely contain scattered, but small beds
of SAV that are principally located along the marsh banks or headwaters of
the tributaries. The concentration of SAV in the Chickahominy River still
persists (46 hectares) and represents the most distinct beds found in the
entire section. The species found in these upriver and marsh creek areas
are fresh to brackish water species such as C. demersum. E. canadensis and
Na.ias spp.

SUMMARY
The distribution and abundance of submerged aquatic vegetation (SAV)
was mapped for the entire Chesapeake Bay in 1985. Color aerial photography
at a scale of 1:12,000 was used to map the Upper and Middle Bay zones, while
black and white photography at a scale of 1:24,000 was used to map the Lower
Bay zone. As a whole, the Chesapeake Bay had 19,390 hectares of SAV in
1985, a 26% increase over the 15,400 hectares in 1984.
The Upper Bay zone had 3,025 hectares of SAV in 1985 (15.6% of the
total SAV in the bay). This represents a decrease of 4.5% from that
reported in 1984. Sixty-six percent of the SAV in this zone was located in
the Susquehanna Flats section. Three of the four sections in this zone
showed a slight decrease in SAV abundance, while a 142% increase was seen in
the sparsely vegetated (104 ha) Upper Eastern Shore section, principally
along the Elk and Sassafras Rivers. SAV beds in the Upper Bay zone
consisted of 13 species. Dominant species in the Susquehanna Flats were
Mvriophvllum spicatum. Hvdrilla verticillata. and Vallisneria americana.
while the Chester River was dominated by Potamogeton perfoliatus and Ruppia
maritima.
The Middle Bay zone had 4986 hectares of SAV in 1985 (25.7% of the
total SAV in the bay), which represents a 389% increase from that reported
in 1984. All sections in the zone showed an increase in SAV, with the vast
majority (3,072 ha) of the SAV and the greatest percent changes occurring in
the Eastern Bay (441%), Choptank River (1760%), and Middle Eastern Shore
(3504%) sections, located on the Eastern Shore of the mainstem of the bay.
The Patuxent River, although sparsely vegetated, showed a 401% increase in
SAV, from 9 hectares in 1984 to 44 hectares in 1985. Both Potomac River
60
-------
sections increased in SAV in 1985, with the largest increase (140%)
occurring in the Upper Potomac River section. A portion of the 59% increase
documented in the Lower Potomac River is most likely the result of more
complete aerial photographic coverage than was obtained in 1984.
SAV beds in the mainstem of the Middle Bay zone consisted principally
of Ruppia maritima. with about six other species being reported. The
Potomac River SAV bed consisted of fourteen different species, with the most
prevalent being Mvriophvllum soicatum and Hvdrilla verticillata.
The return of SAV in the Upper Potomac River continues to be of
significance with regard to its rapid spread in a short time frame. In less
than five years, SAV has increased from almost nothing to 1440 hectares.
Although H. verticillata is one of the dominant species, other species
coexist and, in some areas, share the dominant role with H. verticillata.
The Lower Bay zone had 11,379 hectares of SAV in 1985 (58.7% of the
total SAV in the bay). This amount was similar to that reported for 1984.
Sixty-eight percent of the SAV in this zone is found along the bayside of
the Eastern Shore, with the major beds being located on the broad, shallow
flats in and adjacent to Tangier and Smith Islands. SAV beds are
concentrated at the mouths of the major bayside creeks, principally
Cherrystone Inlet, Hungars Creek, Mattawoman Creek, Occahannock Creek,
Craddock Creek, Pungoteague Creek and Onancock Creek. Along the western
shore of the zone, SAV beds are found in the Back River, Drum Island Flats
adjacent to Plum Tree Island, the mouth of the York River adjacent to the
Guinea Marshes, along the shoreline of the Mobjack Bay and in a small band
from New Point Comfort to Horn Harbor. There were no major changes in SAV
distribution in the nine sections in this zone. The largest change occurred
in the Reedville section where SAV distribution decreased 34% from 1984.
61
-------
SAV beds consist of principally two species, Zostera marina and Ruppia
maritima. Zannichelia palustris has also been found in small isolated
patches, but is not considered a dominant species here.
SAV was still absent in two of the six historical areas from the lower
Bay Zone (Mumfort Island and Parrott Island). SAV increased in the Jenkins
Neck area (17%) but decreased in the East River (33%), Fleets Bay (15%) and
Vaucluse Shores (6%) areas from that reported in 1984. Changes in the
Vaucluse Shore area are related to the dynamic nature of the sand bars and
sand spits that continually alter the available area for SAV growth.
Changes in the East River and Fleets Bay distribution occurred in beds that
were very patchy. These types of beds are more susceptible to physical
damage from storms and can easily change in time periods of less than one
year.
Zostera marina transplanted to unvegetated areas in the Piankatank
and York Rivers between 1982 and 1985 have persisted, and in some cases, are
rapidly expanding. These areas are being closely monitored by VIMS'
scientists to assess overall changes in distribution of these transplants
with time.
