Go to First Page <br />Wetland name or number A <br />These questions apply to wetlands of all HGM classes. <br />HABITAT FUNCTIONS - Indicators that site functions to provide important habitat <br />H 1.0. Does the site have the potential to provide habitat? <br />H 1.1. Structure of plant community: Indicators are Cowardin classes and strata within the Forested class. Check the <br />Cowardin plant classes in the wetland. Up to 10 patches may be combined for each class to meet the threshold <br />of % ac or more than 10% of the unit if it is smaller than 2.5 oc. Add the number of structures checked. <br />Aquatic bed 4 structures or more: points = 4 <br />✓ Emergent 3 structures: points = 2 <br />1 <br />✓ Scrub -shrub (areas where shrubs have > 30% cover) 2 structures: points = 1 <br />Forested (areas where trees have > 30% cover) 1 structure: points = 0 <br />If the unit has a Forested class, check if: <br />The Forested class has 3 out of 5 strata (canopy, sub -canopy, shrubs, herbaceous, moss/ground-cover) <br />that each cover 20% within the Forested polygon <br />H 1.2. Hydroperiods <br />Check the types of water regimes (hydroperiods) present within the wetland. The water regime has to cover <br />more than 10% of the wetland or % ac to count (see text for descriptions of hydroperiods). <br />Permanently flooded or inundated 4 or more types present: points = 3 <br />Seasonally flooded or inundated 3 types present: points = 2 <br />Occasionally flooded or inundated 2 types present: points = 1 <br />0 <br />✓ Saturated only 1 type present: points = 0 <br />Permanently flowing stream or river in, or adjacent to, the wetland <br />_Seasonally flowing stream in, or adjacent to, the wetland <br />_Lake Fringe wetland 2 points <br />Freshwater tidal wetland 2 points <br />H 1.3. Richness of plant species <br />Count the number of plant species in the wetland that cover at least 10 ftz. <br />Different patches of the some species can be combined to meet the size threshold and you do not have to name <br />the species. Do not include Eurasian milfoil, reed canarygrass, purple loosestrife, Canadian thistle <br />1 <br />If you counted: > 19 species points = 2 <br />5 - 19 specie points = 1 <br />< 5 species points = 0 <br />H 1.4. Interspersion of habitats <br />Decide from the diagrams below whether interspersion among Cowardin plants classes (described in H 1.1), or <br />the classes and unvegetated areas (can include open water or mudflats) is high, moderate, low, or none. If you <br />have four or more plant classes or three classes and open water, the rating is always high. <br />Oo <br />1 <br />None = 0 points IlLow = 1 point Moderate = 2 points <br />All three diagrams <br />in this row <br />are HIGH = 3points <br />Wetland Rating System for Western WA: 2014 Update 13 <br />Rating Form - Effective January 1, 2015 <br />
