4. the below to sketch out a map of your wetlands and mark
up to three observational points you will be using. In your drawing,
include areas of open water, vegetation, and observed water inflows
and outflows.
5. Estimate the size, in acres, of the wetland, excluding the buffer.
Q Less than one acre acres
6. The average buffer width around each of the wetlands is
north
south
east
west
Q no apparent buffer
Q 50 to 100 feet
a less than 50 feet
a More than 100 feet
-------
7. To further define the wetland, please check the vegetation type
which is most appropriate:
a The dominant (more than 30%) type of vegetation is trees and
shrubs over 20 feet tail (forested)
a The dominant (more than 30%) vegetation is woody vegetation
than 20 feet tall (shrub-scrub)
a The dominant (more than 30%) vegetation is grasses and plants
that have fleshy and not woody stems (emergent)
Draw the of vegetation on your map.
8. Another important factor in describing wetlands is the
and extent of water.
Check the description(s) which best describes the wetland.
Q There is standing fresh water. If so, is it:
a Seasonal, or a year round
Q There is tidal influence and standing water at a high tide.
a There is no visible standing water at time of visit.
a No, but there is evidence of past standing water.
LJ There is flowing water.
If water is present, estimate how much area of the wetlands is
covered in water.
a o% - 30% a 30% - 60% a eo% -100%
If there is no standing water, is the soil soggy?
(Test for sogginess: Do your shoes become wet when walking on
soils? When you squeeze a dump of soil, does water seep out?)
ayes a no, but the soil is damp a no, the soil is dry
Identify any visible areas or structures through which water flows into
the wetlands and then draw and label them on your map.
LJ streams LJ culverts LJ ditches
a storm drains LI ponds, lakes, estuaries LI pump
Identify any visible areas or structures through which water flows out
of the wetlands and then draw and label them on your map.
LJ streams LJ culverts LJ ditches
a storm drains LI ponds, lakes, estuaries LJ pump
9. A healthy wetland is home to a variety of animals.
Please indicate the observations you made while visiting your
wetland.
The following wildlife have during this Wetlands Walk.
(Please identify the species, if possible.)
a fish a aquatic insects D flying insects
a birds LJ ducks a frogs
Q lizards LJ snakes a rabbits
a mice a deer a domestic animals
(cats, dogs)
-------
9. Animals. (Cont.)
Carcasses of dead fish or other wildlife have been seen during this
Wetlands Walk. (Please mark the location of the carcasses on your
wetlands map and identify the species if possible.)
LJ yes LJ no
Please specify:
Evidence (scat, tracks) of the following have been seen during this
Wetlands Walk.
Q birds a ducks LJ frogs a snakes
LJ rabbits LJ mice LJ deer
LI domestic animals (cats, dogs)
10. Indicate which of the following land are found in or
to the wetland. Be sure to include these observations on
your wetlands map.

L3 Residential housing
Q Construction site
a Agriculture, livestock grazing, or cultivation of crops
Q Non industrial commercial development (e.g. office buildings,
stores, gas stations)
Q Industrial development
Q Logging
a Roads, paved or unpaved
Q Railroads
11. Indicate which, if any, of the following activities appear to be
taking place within the wetlands area.
LJ dumping of soil, gravel and/or vegetation
Q dumping of man-made materials
LJ grading, evidenced by tracks and scraped soil
Q draining of water evidenced by pipes or ditches leading out of the
wetland
L3 channelizing of water evidenced by ditches or trenches
Q bulkheads built between shore and wetland
L3 tracks of recreational vehicles
Q livestock access, evidenced by animals observed in the area, or
animal tracks
Q pipes or culverts which transport storm water from parking lots or
roads into the wetland
-------
12. Indicate which, if any, of the following signs of wetlands
degradation is present.
LI silt, sand or gravel deposits
