1. Ground Surface Condition/Vegetation Condition — assessment area condition metric
Check a box in each column. Consider alteration to the ground surface (GS) in the assessment area and vegetation structure (VS) in the
assessment area. Compare to reference wetland if applicable (see User Manual). If a reference is not applicable, then rate the assessment
area based on evidence an effect.
GS VS
®A ❑A Not severely altered
❑B ®B Severely altered over a majority of the assessment area (ground surface alteration examples: vehicle tracks, excessive
sedimentation, fire -plow lanes, skidder tracks, bedding, fill, soil compaction, obvious pollutants) (vegetation structure
alteration examples: mechanical disturbance, herbicides, salt intrusion [where appropriate], exotic species, grazing, less
diversity [if appropriate], hydrologic alteration)
Surface and Sub -Surface Storage Capacity and Duration — assessment area condition metric
Check a box in each column. Consider surface storage capacity and duration (Surf) and sub -surface storage capacity and duration (Sub).
Consider both increase and decrease in hydrology. A ditch <_ 1 foot deep is considered to affect surface water only, while a ditch > 1 foot
deep is expected to affect both surface and sub -surface water. Consider tidal flooding regime, if applicable.
Surf Sub
❑A ❑A Water storage capacity and duration are not altered.
®B ®B Water storage capacity or duration are altered, but not substantially (typically, not sufficient to change vegetation).
❑C ❑C Water storage capacity or duration are substantially altered (typically, alteration sufficient to result in vegetation change )
(examples: draining, flooding, soil compaction, filling, excessive sedimentation, underground utility lines).
Water Storage/Surface Relief — assessment area/wetland type condition metric (skip for all marshes)
Check a box in each column. Select the appropriate storage for the assessment area (AA) and the wetland type (WT).

Discharge into Wetland - opportunity metric
Check a box in each column. Consider surface pollutants or discharges (Surf) and sub -surface pollutants or discharges (Sub). Examples
of sub -surface discharges include presence of nearby septic tank, underground storage tank (UST), etc.
Surf Sub
®A ®A Little or no evidence of pollutants or discharges entering the assessment area
❑B ❑B Noticeable evidence of pollutants or discharges entering the wetland and stressing, but not overwhelming the
treatment capacity of the assessment area

potentially overwhelming the treatment capacity of the wetland (water discoloration, dead vegetation, excessive
sedimentation, odor)
6. Land Use - opportunity metric (skip for non -riparian wetlands)
Check all that apply (at least one box in each column). Evaluation involves a GIS effort with field adjustment. Consider sources draining
to assessment area within entire upstream watershed (WS), within 5 miles and within the watershed draining to the assessment area (5M),
and within 2 miles and within the watershed draining to the assessment area (2M).

❑B Sediment deposition is excessive, but not overwhelming the wetland.
❑C Sediment deposition is excessive and is overwhelming the wetland.
11. Wetland Size — wetland type/wetland complex condition metric
Check a box in each column. Involves a GIS effort with field adjustment. This metric evaluates three aspects of the wetland area: the
size of the wetland type (WT), the size of the wetland complex (WC), and the size of the forested wetland (FW) (if applicable, see User
Manual). See the User Manual for boundaries of these evaluation areas. If assessment area is clear-cut, select "K" for the FW column.

❑A Pocosin is the full extent (>_ 90%) of its natural landscape size.
❑B Pocosin type is < 90% of the full extent of its natural landscape size.
13. Connectivity to Other Natural Areas — landscape condition metric
13a. Check appropriate box(es) (a box may be checked in each column). Involves a GIS effort with field adjustment. This metric
evaluates whether the wetland is well connected (Well) and/or loosely connected (Loosely) to the landscape patch, the contiguous
naturally vegetated area and open water (if appropriate). Boundaries are formed by four -lane roads, regularly maintained utility line
corridors the width of a four -lane road or wider, urban landscapes, maintained fields (pasture and agriculture), or open water > 300
feet wide.

14. Edge Effect — wetland type condition metric (skip for all marshes and Estuarine Woody Wetland)
May involve a GIS effort with field adjustment. Estimate distance from wetland type boundary to artificial edges. Artificial edges include
non -forested areas >_ 40 feet wide such as fields, development, roads, regularly maintained utility line corridors, and clear -cuts. Consider
the eight main points of the compass. Artificial edge occurs within 150 feet in how many directions? If the assessment area is clear cut,
select option "C."
❑A 0
❑ B 1 to 4
®C 5to8
15. Vegetative Composition — assessment area condition metric (skip for all marshes and Pine Flat)
❑A Vegetation is close to reference condition in species present and their proportions. Lower strata composed of appropriate
species, with exotic plants absent or sparse within the assessment area.
❑B Vegetation is different from reference condition in species diversity or proportions, but still largely composed of native species
characteristic of the wetland type. This may include communities of weedy native species that develop after clearcutting or clearing.
It also includes communities with exotics present, but not dominant, over a large portion of the expected strata.
❑C Vegetation severely altered from reference in composition, or expected species are unnaturally absent (planted stands of non -
characteristic species or at least one stratum inappropriately composed of a single species), or exotic species are dominant in at
least one stratum.
16. Vegetative Diversity — assessment area condition metric (evaluate for Non -tidal Freshwater Marsh only)
❑A Vegetation diversity is high and is composed primarily of native species (< 10% cover of exotics).
❑B Vegetation diversity is low or has > 10% to 50% cover of exotics.
❑C Vegetation is dominated by exotic species (> 50 % cover of exotics).
17. Vegetative Structure — assessment area/wetland type condition metric
17a. Is vegetation present?
®Yes ❑No If Yes, continue to 17b. If No, skip to Metric 18.
17b. Evaluate percent coverage of assessment area vegetation for all marshes only. Skip to 17c for non -marsh wetlands.
❑A >_ 25% coverage of vegetation
❑B < 25% coverage of vegetation
17c. Check a box in each column for each stratum. Evaluate this portion of the metric for non -marsh wetlands. Consider
structure in airspace above the assessment area (AA) and the wetland type (WT) separately.

22. Hydrologic Connectivity — assessment area condition metric (evaluate for riparian wetlands and Salt/Brackish Marsh only)
Examples of activities that may severely alter hydrologic connectivity include intensive ditching, fill, sedimentation, channelization, diversion,
man-made berms, beaver dams, and stream incision. Documentation required if evaluated as B, C, or D.
❑A Overbank and overland flow are not severely altered in the assessment area.
❑B Overbank flow is severely altered in the assessment area.
❑C Overland flow is severely altered in the assessment area.
❑D Both overbank and overland flow are severely altered in the assessment area.
Notes
Vegetation modified/mainitained at low height due to airport activity and saftey. Wetland surrounded by maintained low, herbaceous vegetation.
Appears to lack significant hydrologic connection. Wetland subject to higher tempertures (air temp and soil temp) from lack of surroundging
vegetation buffer.
