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 of an effect.

sub -surface water. Consider tidal flooding regime, if applicable.

Ex:posed — adjacent open water with width >_ 2500 feet or regular boat traffic.
8. Wetland Width at the Assessment Area — wetland type/wetland complex metric (evaluate for riparian wetlands only)

• 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

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
evaluates whether the wetland is well connected (Well) and/or loosely connected (Loosely) to the landscape patch, the contiguous
metric 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, fields (pasture open and agriculture), or water > 300 feet wide.

A A >_ 500 acres
B C B From 100 to < 500 acres
C * C From 50 to < 100 acres
D C D From 10 to < 50 acres
E C E < 10 acres

13b. Evaluate for marshes only.
Yes No Wetland type has a surface hydrology connection to open waters/stream or tidal wetlands.
14. Edge Effect — wetland type condition metric (skip for all marshes)
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.
A No artificial edge within 150 feet in all directions
B No artificial edge within 150 feet in four (4) to seven (7) directions
• C An artificial edge occurs within 150 feet in more than four (4) directions or assessment area is clear-cut
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. Expected species are unnaturally absent (planted stands of non -
characteristic species or at least one stratum inappropriately composed of a single species). 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).
