RATING OF WETLANDS IN WASHINGTON

· Category 1 - Highest Quality

verified habitat for E&T species
Bog/Fen and Forested Wetlands - mature trees
>7.5 acres with > 3 wetland subclasses including open water
connected to another habitat area

· Category 2 - High Quality

E&T habitat
Forested Wetland outside urban area > 1 acre
Heron rookery
Spawning habitat for anadromous fish
>10 acres with >2 wetland classes including open water
>5 acres with > 3 wetland subclasses including open water
connected to another habitat area

· Category 3 - More common than 1 and 2

Headwater with >5 cfs
Streams utilized by salmonids (intermittent or perennial)
Perennial streams not used by salmonids
Forested wetland within urban area

· Category 4 - Small, isolated, less diverse vegetation

Altered by prior legal activities and if left alone would revert
Regulated man-made drainage facilities in natural wetland
Intermittent streams without salmonids

· Category 5 - Marginal wetlands

Isolated, with only 1 wetland class with >90% exotic species
Altered by prior legal activities and if left alone would not revert
