<br /> SC 1.0. Estuarine wetlands
<br /> Does the wetland meet the following criteria for Estuarine wetlands?
<br /> =The dominant water regime is tidal,
<br /> =Vegetated, and
<br /> With a salinity greater than 0.5 plat C Yes—Go to SC 1.1 ✓ No=Not an estuarine wetland
<br /> SC 1.1. Is the wetland within a National Wildlife Refuge, National Park, National Estuary Reserve, Natural Area
<br /> Preserve,State Park or Educational, Environmental,or Scientific Reserve designated under WAC 332-30-151? Cat.
<br /> [' Yes=Category I�No-Go to SC 1.2
<br /> SC 1.2. Is the wetland unit at least 1 ac in size and meets at least two of the following three conditions?
<br /> =The wetland is relatively undisturbed(has no diking,ditching,filling,cultivation,grazing,and has less
<br /> Cat.
<br /> than 10%cover of non-native plant species. (If non-native species are Spartina,see page 25)
<br /> =At least%of the landward edge of the wetland has a 100 ft buffer of shrub,forest,or un-grazed or un-
<br /> mowed grassland. Cat. It
<br /> =The wetland has at least two of the following features:tidal channels,depressions with open water,or
<br /> contiguous freshwater wetlands. Yes=Category 1 CNo=Category 11
<br /> SC 2.0. Wetlands of High Conservation Value (WHCV)
<br /> SC 2.1. Has the WA Department of Natural Resources updated their website to include the list of Wetlands of High
<br /> Conservation Value? F7 Yes—Go to SC 2.2 ' No—Go to SC 2 31 Eat.
<br /> SC 2.2. Is the wetland listed on the WDNR database as a Wetland of High Conservation Value?
<br /> Yes=Category 1 C No=Not a WHCV
<br /> SC 2.3. Is the wetland in a Section/Township/Range that contains a Natural Heritage wetland?
<br /> http•//wwwl dnr wa gov/nhp/refdesk/datasearch/wnhpwet[ands.pdf
<br /> Yes—Contact WNHP/WDNR and go to SC 2.4 F�o =Not a WHCV

<br /> their website? Yes=Category I E__� No=Not a WHCV
<br /> SC 3.0. Bogs
<br /> Does the wetland (or any part of the unit) meet both the criteria for soils and vegetation in bogs?Use the key
<br /> below.if you answer YES you will still need to rate the wetland based on its functions.
<br /> SC 3.1. Does an area within the wetland unit have organic soil horizons,either peats or mucks,that compose 16 in or
<br /> more of the first 32 in of the soil profile? C Yes—Go to SC 3.3 C; o—Go to SC 3.2
<br /> SC 3.2. Does an area within the wetland unit have organic soils,either peats or mucks,that are less than 16 in deep
<br /> over bedrock,or an impermeable hardpan such as clay or volcanic ash,or that are floating on top of a lake or
<br /> pond? _Yes—Go to SC 3.3 � No=Is not a bog
<br /> SC 3.3. Does an area with peats or mucks have more than 70%cover of mosses at ground level,AND at least a 30%
<br /> cover of plant species listed in Table 4? Yes=Is a Category I bog E, No— Go to SC 3.4
<br /> NOTE: If you are uncertain about the extent of mosses in the understory,you may substitute that criterion by
<br /> measuring the pH of the water that seeps into a hole dug at least 16 in deep.If the pH is less than 5.0 and the
<br /> plant species in Table 4 are present,the wetland is a bog. Cat.
<br /> SC 3.4. Is an area with peats or mucks forested(>30%cover)with Sitka spruce,subalpine fir,western red cedar,
<br /> western hemlock, lodgepole pine,quaking aspen, Engelmann spruce,or western white pine,AND any of the
<br /> species(or combination of species)listed in Table 4 provide more than 30%of the cover under the canopy?
<br /> F7 F_' Yes=Is a Category I bog C No=Is not a bog
