Wetland name or number <br /> WDFW Priority Habitats <br /> Priority habitats listed by WDFW'(see complete descriptions of WDFW priority habitats,and the counties in <br /> which they can be found,in:Washington Department of Fish and Wildlife.2008.Priority.Habitat and Species <br /> List.Olympia,Washington.177 pp. <br /> http://wdfw.wa.gov/publications/00165/wdfw00165.ridf or access the list from here: <br /> http.//wdfw.wa.aov/conservation/phs/list/ <br /> Count how many of the following priority habitats are within 330 ft(100 m)of the wetland unit: NOTE:This <br /> question is independent of the land use between the wetland unit and the priority habitat. <br /> O Aspen Stands:Pure or mixed stands of aspen greater than 1 ac(0.4 ha). <br /> ❑ Blodiversity Areas and Corridors:Areas of habitat that are relatively important to various species <br /> of native fish and wildlife(full descriptions in WDFW PHS report). <br /> O Herbaceous Raids:Variable size patches of grass and forbs on shallow soils over bedrock. <br /> O Old-growth/Mature forests: Old-growth west of Cascade crest—Stands of at least 2 tree species, <br /> forming a multi-layered canopy with occasional small openings;with at least 8 trees/ac(20 trees/ha) <br /> >32 in(81 cm)dbh or>200 years of age. Mature forests—Stands with average diameters <br /> exceeding 21 in(53 cm)dbh; crown cover may be less than 100%;decay,decadence,numbers of <br /> snags,and quantity of large downed material is generally less than that found in old-growth;80-200 <br /> years old west of the Cascade crest. <br /> ❑ Oregon White Oak:Woodland stands of pure oak or oak/conifer associations where canopy <br /> coverage of the oak component is important(full descriptions in WDFW PHS report p. 158—see <br /> web link above). <br /> ❑ Riparian:The area adjacent to aquatic systems with flowing water that contains elements of both <br /> aquatic and terrestrial ecosystems which mutually influence each other. <br /> ❑ Westside Prairies:Herbaceous,non-forested plant communities that can either take the form of a <br /> dry prairie or a wet prairie(full descriptions in WDFW PHS report p. 161—see web link above). <br /> ❑ lnstream:The combination of physical,biological,and chemical processes and conditions that <br /> interact to provide functional life history requirements for instream fish and wildlife resources. <br /> i7 Nearshore: Relatively undisturbed nearshore habitats.These include Coastal Nearshore,Open <br /> Coast Nearshore,and Puget Sound Nearshore.(full descriptions of habitats and the definition of <br /> relatively undisturbed are in WDFW report—see web link on previous page). <br /> ❑ Caves:A naturally occurring cavity,recess,void,or system of interconnected passages under the <br /> earth in soils,rock,ice,or other geological formations and is large enough to contain a human. <br /> ❑ Cliffs:Greater than 25 ft(7.6 m)high and occurring,below 5000 ft elevation. <br /> ❑ Talus:Homogenous areas of rock rubble ranging In average size 0.5-6.5 ft(0.15-20 m) <br /> composed of basalt,andesite,and/or sedimentary rock,including riprap slides and mine tailings. <br /> May be associated with cliffs. <br /> O Snags and Logs:Trees are considered snags if they are dead or dying and exhibit sufficient decay <br /> characteristics to enable cavity excavation/use by wildlife.Priority snags have a diameter at breast <br /> height of>20 in((51 cm)in western Washington and are>6.5 ft(2 m)in height.Priority logs are> <br /> 12 in(30 cm)in diameter at the largest end,and>20 fit(6 m)long. <br /> Note:All vegetated wetlands are by definition a priority habitat but are not included in this list because they <br /> are addressed elsewhere. <br /> Wetland Rating System for Western WA 2014 Update <br /> Rating Form-Effective January 1,2015 9 WSDOT Adapted Form March 2,2015 <br />
