• Wetland name or number A These questions apply to wetlands of all HGM classes. HABITAT FUNCTIONS-Indicators that site functions to provide important habitat H 1,0. Does the site have the potential to provide habitat? H 1.1.Structure of plant community:indicators are Cowardin classes and strata within the Forested class. Check the Cowardin plant classes in the wetland. Up to 10 patches maybe combined for each class to meet the threshold of%ac or more than 10%of the unit if it is smaller than 2.5 ac.Add the number of structures checked. ❑ Aquatic bed 4 structures or more: points=4 ❑ Emergent 3 structures: points=2 O Scrub-shrub(areas where shrubs have>30%cover) 2 structures: points- 1 ❑ Forested (areas where trees have> 30%cover) 1 structure:points=0 If the unit has a Forested class, check if: ❑ The Forested class has 3 out of 5 strata(canopy, sub-canopy,shrubs, herbaceous, moss/ground-cover)that each cover 20%within the Forested polygon H 1.2.Hydroperiods Check the types of water regimes(hydroperiods)present within the wetland.The water regime has to cover more than 10% of the wetland or ac to count(see text for descriptions of hydroperiods). ❑ Permanently flooded or inundated 4 or more types present: points=3 • Seasonally flooded or inundated 3 types present: points=2 2 ❑ Occasionally flooded or inundated 2 types present:points= 1 O Saturated only 1 types present: points=0 Permanently flowing stream or river in,or adjacent to,the wetland ❑ Seasonally flowing stream in,or adjacent to,the wetland ❑ Lake Fringe wetland 2 points ❑ Freshwater tidal wetland 2 points H 1.3. Richness of plant species Count the number of plant species in the wetland that cover at least 10 ft2. Different patches of the same species can be combined to meet the size threshold and you do not have to name the species. Do not include Eurasian milfoil,reed canarygrass,purple loosestrife, Canadian thistle 1 If you counted: >19 species points=2 5-19 species points= 1 <5 species points=0 H 1.4. Interspersion of habitats Decide from the diagrams below whether interspersion among Cowardin plants classes (described in H 1.1),or the classes and unvegetated areas(can include open water or mudflats) is high, moderate,low,or none. If you have four or more plant classes or three classes and open water,the rating is always high. C:D1 0 c� 2 None=0 points Low= 1 point Moderate =2 points All three diagrams in this row are HIGH=3 points V Wetland Rating System for Western WA:2014 Update Rating Form-Effective January 1,2015 7 WSDOT Adapted Form-March 2,2015
