If you answer YES you will still need to rate the wetland based on its functions. ❑ Old-growth forests (west of Cascade crest): Stands of at least two tree species, forming a multi-layered canopy with occasional small openings;with at least 8 trees/ac (20 trees/ha)that are at least 200 years of age OR have a diameter at breast height (dbh)of 32 in (81 cm)or more. ❑ Mature forests(west of the Cascade Crest): Stands where the largest trees are 80- 200 years old OR the species that make up the canopy have an average diameter (dbh)exceeding 21 in (53 cm). •❑ Yes=Category I 0 No= Not a forested wetland for this section SC 5.0.Wetlands in Coastal Lagoons Does the wetland meet all of the following criteria of a wetland in a coastal lagoon? ❑ The wetland lies in a depression adjacent to marine waters that is wholly or partially separated from marine waters by sandbanks, gravel banks, shingle, or, less frequently, rocks ❑ The lagoon in which the wetland is located contains ponded water that is saline or brackish (>0.5 ppt)during most of the year in at least a portion of the lagoon(needs to be measured near the bottom) ❑ Yes-Go to SC 5.1 0 No= Not a wetland in a coastal lagoon SC 5.1. Does the wetland meet all of the following three conditions? ❑ The wetland is relatively undisturbed (has no diking, ditching,filling, cultivation, grazing), and has less than.20% cover of aggressive, opportunistic plant species(see list of species on p. 100). ❑ At least%of the landward edge of the wetland has a 100 ft buffer of shrub,forest, or un• grazed or un-mowed grassland. ❑ The wetland is larger than 1/10 ac(4350 ft2) ❑Yes=Category I 0 No=Category II SC 6.0. Interdunal Wetlands Is the wetland west of the 1889 line(also called the Western Boundary of Upland Ownership or WBUO)?If you answer yes you will still need to rate the wetland based on its habitat functions. In practical terms that means the following geographic areas: ❑ Long Beach Peninsula: Lands west of SR 103 ❑ Grayland-Westport: Lands west of SR 105 ❑ Ocean Shores-Copalis: Lands west of SR 115 and SR 109 ❑ Yes-Go to SC 6.1 0 No= Not an interdunal wetland for rating SC 6.1. Is the wetland 1 ac or larger and scores an 8 or 9 for the habitat functions on the form (rates H,H,H or H,H,M for the three aspects of function)? ❑ Yes=Category I 0 No-Go to SC 6.2 SC 6.2. Is the wetland 1 ac or larger, or is it in a mosaic of wetlands that is 1 ac or larger? O Yes=Category II 0 No-Go to SC 6.3 SC 6.3. Is the unit between 0.1 and 1 ac, or is it in a mosaic of wetlands that is between 0.1 and 1 ac? ❑ Yes=Category III ❑ No=Category IV Category of wetland based on Special Characteristics If you answered No for all types, enter"Not Applicable"on Summary Form Wetland Rating System for Western WA:2014 Update Rating Form-Effective January 1,2015 11 WSDOT Adapted Form-March 2,2015
