Wetland name or number SC 2.0 Natural Heritage Wetlands (seep. 87) Natural Heritage wetlands have been identified by the Washington Natural Heritage Program/DNR as either high quality undisturbed wetlands or wetlands that support state Threatened, Endangered, or Sensitive plant species. SC 2.1 Is the wetland being rated in a Section/Township/Range that contains a Natural Heritage wetland? (this question is used to screen out most sites before you need to contact WNHP/DNR) S/T/R information from Appendix D ❑ or accessed from WNHP/DNR web Cat. I site ❑ YES❑—contact WNHP/DNR(see p. 79) and go to SC 2.2 NO ❑ SC 2.2 Has DNR identified the wetland as a high quality undisturbed wetland or as or as a site with state threatened or endangered plant species? YES =Category I NO n Not a Heritage Wetland SC 3.0 Bogs (seep. 87) Does the wetland(or any part of the unit)meet both the criteria for soils and vegetation in bogs? Use the key below to identifyif the wetland is a bog. If you answer yes,you will still need to rate the wetland based on its functions. 1. Does the wetland have organic soils horizons (i.e. layers of organic soil), either peats or mucks, that compose 16"or more of the first 32 inches of the soil profile? (See Appendix B for afield key to identify organic soils.) Yes - go to Q.3 NO - go to Q.2 2. Does the wetland have organic soils, either peats or mucks, that are less than 16 inches deep over bedrock or an impermeable hardpan such as clay or volcanic ash, or that are floating on top of a lake or pond? Yes - go to Q.3 NO ❑is not a bog for purpose of rating 3. Does the wetland have more than 70%cover of mosses at ground level, AND other plants, if present, consist of the"bog" species listed in Table 3 as a significant component of the vegetation(more than 30%of the total shrub and herbaceous cover consists species in Table 3)? Yes—Is a bog for purpose of rating NO - go to Q.4 NOTE:If you are uncertain about the extent of mosses in the understory, you may substitute that criterion by measuring the pH of the water that seeps into a hole dug at least 16"deep. If the pH is less than 5.0 and the "bog"plant species in Table 3 are present, the wetland is a bog. Cat. I 4. Is the wetland forested(>30%cover)with sitka spruce, subalpine fir, western red cedar,western hemlock, lodgepole pine, quaking aspen, Englemann's spruce, or western white pine,WITH any of the species (or combination of species) on the bog species plant list in Table 3 as a significant component of the ground cover(>30%coverage of the total shrub/herbaceous cover)? YES = Category I NO ❑ is not a bog for purpose of rating Wetland Rating Form—western Washington 13 August 2004 Version 2 Updated with new WDFW definitions Oct.2008
