The delineation was performed on February 15,2007. For the purposes of federal, Washington State, and Mason County jurisdictional oversight, methodology used for the wetland delineation is consistent with the definition provided in paragraph 25a of the Washington State Wetlands Identification and Delineation Manual (Washington State Department of Ecology [Ecology] 1997). The sections below provide: (1) an introduction to the site; (2) a description of methods used in the field delineation; and (3) technical results. GENERAL SITE CONDITIONS The subject property is located in the SE 1/4 of Section 34, Township 21 North, and Range 03 West (Figure 1). The parcel is roughly rectangular in shape and is 0.8 acres. The parcel is bordered to the west by a 7.1-acre wetland identified as Catfish Lake, to the east by Catfish Lake Road, and to the north and south by residential land use. Since the lake is less than 20 acres, it is designated as a wetland according to Section 17.01.070B of the Mason County Resource Ordinance. The entire property is generally comprised of three vegetative communities; the easternmost portion of the ownership contains wetland vegetation along the fringe of Catfish Lake, including spirea, scouler willow, and salmonberry with lesser amounts of slough sedge. The area west of the wetland vegetation is comprised of a moderate gradient slope down toward Catfish Lake, with a dense forested/shrub community of Douglas fir, evergreen huckleberry, salal, and oceanspray. The entire western half of the ownership, atop the slope, has been maintained as a flat lawn area with scattered forested/shrub vegetation, for recreational purposes. A septic and well is located within the lawn area. The site contains no existing buildings or structures within the parcel, with the exception of a travel trailer currently located within the lawn area. PO Rox 2R54 Relfair.

General information sources included: United States Geological Survey (USGS) topographic maps, 1974 United States Fish and Wildlife Service (USFWS)National Wetland Inventory (NWI)maps,Soil Survey of Mason County Area, Washington (United States Department of Agriculture [USDA] 1951), and Mason County's critical areas regulations—Mason County Code, Wetlands(17.01.070). Field Delineation Methodology used for wetland delineation was consistent with the technical approaches articulated in the 1997 Manual. This document is the wetland delineation manual that is used in determining wetland areas when applying state and local government regulations under the Shoreline Management Act and the Growth Management Act in Washington State. The extent and location of project related wetlands were determined during field work performed on February 15, 2007. Field work was conducted under rainy conditions with an ambient temperature of approximately 45 degrees Fahrenheit. The time of year and recent precipitation history were considered in assessing the type and extent of wetlands presumed to exist on and in proximity to the site. Specific field methodology used in determining the extent and location of wetland areas include: 1. As part of the initial project site reconnaissance, the site was walked to determine the general extent and location of potential wetland areas; 2. Wetland and upland sample plots were established in the identified potential wetland areas and in the adjacent upland area; and 3. Wetland boundaries were delineated with flagging by noting localized topography and vegetation patterns and comparing parameters of hydrology, soil, and vegetation with data collected at the wetland and upland sample plots. Data collected at each sample plot were entered onto a Routine Wetland Determination Data Form(Ecology 1997). Copies of data forms for each sample plot are provided in Appendix B. WETLAND EVALUATION The subject wetland was characterized using the wetland classes defined by the Cowardin system (Cowardin et al. 1979). The Cowardin system describes wetlands by the plant communities, soils and hydrologic regimes present. The naming convention was developed by the USFWS for the NWI maps. Wetlands were also classified and rated using the categories set forth in Mason County Resource Ordinance, which defines wetland categories according to Washington State PO Box 2954 Relfair_Washington 9R52R•Cell Phone 360-620-061 R•Office Phone 360-372-2421•boad40naneonlenc_com Strange Wetland Delineation TWC07W319 February 15,2007 Page 3 of 8 Wetland Rating System, Western Washington, 2"`t Edition, " or as amended hereafter (Ecology 1993). This wetland evaluation used the new rating manual, Washington State Wetland Rating System for Western Washington (Hruby 2004). This system identifies various complexities within wetland structures, habitat attributes and various functions associated with wetlands. The rating forms completed for this wetland are provided in Appendix C. BACKGROUND INFORMATION Watershed The parcel is located along the southern side of Catfish Lake. Catfish Lake is a headwater wetland that drains into a nonfishbearing stream on the easternmost end of the wetland. The stream transitions to a fishbearing stream approximately 0.5 mile east of the parcel, then drains into Oakland Bay in the South Puget Sound. Mason County Soft Survey The soil survey of Mason County indicates two onsite soil types. The first soil type occupies the majority of the parcel, and has been identified as: Ab-Alderwood gravelly sandy loam, 5 to 15 percent slopes. The Alderwood series consists of brown, well-drained, upland soils. They have developed from mixed gravelly glacial till dominated by acid igneous rock. The imbedded gravel is mainly granite and quartzite. Rainfall is 45 to 60 inches a year. The native vegetation is a dense forest consisting almost entirely of Douglas-fir and a dense understory of salal, Oregon- grape, vine maple, and huckleberry. Northeast of the Hood Canal the understory is mainly rhododendron. Alderwood soils occupy the extensive rolling glacial moraines, and they are the dominant soils in the eastern part of the county. The Alderwood soils are associated with the somewhat excessively drained Everett and Indianola soils and with the moderately well drained Kitsap soils. Shelton and Hoodsport soils differ from the Alderwood soils in that they have developed under high rainfall and from glacial till having a much higher content of basic igneous rock. The Alderwood gravelly sandy loam, 5 to 15 percent slopes (Ab) is the most extensive, soil of the Alderwood series. It occupies undulating to rolling moraines. The second soil type occupies the western portion of the parcel, and has been identified as: McMurray peat, 0 to 2 percent slopes (Me).- The McMurray series consists of peat that is made up largely of the partly decomposed remains of evergreen and decidious trees and of various shrubs that have accumulated in swampy basins, depressions, and low intermittent lakes. Uncleared areas are covered by a dense forest of cedar, spruce, fir, hemlock, alder, maple, vine maple, devilsclub, salal, bracken fern, and occasional areas of skunkcabbage, sedges, and reeds. The McMurray soils are saturated and must be drained before they can be used. Of the peats in Mason County, the McMurray peat is the least acid and the most fertile and desirable for crops. The McMurray soils occur as small areas scattered throughout the county. A more detailed description of this soil is presented in Appendix B. Soil location is illustrated in Figure 4 -Mason Soil Survey map.

(PUBHH). See Figure 3 for the NWI Map. WETLAND DELINEATION RESULTS General Wetland Conditions A portion of one wetland identified as Catfish Lake was delineated on the subject parcel. The portion of the wetland boundary within the parcel has been staked with metal stakes flagged with pink ribbon. The wetland is located on the western edge of the parcel (Figure 2). In general, the wetland is comprised mainly of a shrub-scrub community along the fringe of open water, dominated by spirea and salmonberry and an overstory of red alder. The entire wetland runs north and south off the property for several acres. The outlet for the wetland is a nonfishbearing stream at the northern end of the wetland. Soils Soil analysis within the wetland consisted of three tests pits near the wetland boundary. All wetland test pits revealed similar characteristics with the mapped soil type, McMurray Peat. The test pits revealed that wetland hydric soil is indicated by a low-chroma equaling one throughout the entire soil profile,and the presence of sulfidic odor during test pit excavation. Corresponding upland test pits revealed similar characteristics with the other mapped soil type, Alderwood gravelly sandy loam. The soil beyond the duff layer was a very gravelly sandy loam with matrix chromas varying from IOYR 3/4 to IOYR 4/3. From six to fifteen inches below ground surface the soil was a gravelly sandy loam. It exhibited a high matrix chroma varying from 1 OYR 4/3 to 10 YR 6/3 (Munsell reading)with no mottles. Hydrology Hydrology within the wetland was indicated by drift lines, water marks on trees, sediment deposits, the onsite soil type within wetland boundary (McMurray Peat) is a listed hydric soil, and FAC-neutral vegetation. Nearly the entire wetland is currently inundated to the wetland boundary, and beyond the wetland boundary in the southernmost sample plot. The upland area landward of the southernmost part of the wetland boundary within the parcel is inundated up to 1-foot, where floodwater has spilled into a depressional lawn area adjacent to the wetland boundary. After further observation, the inundated lawn area failed to meet vegetation and soil criteria for positive wetland indicators. Vegetation The wetland vegetation is limited to the outer fringe of the entire wetland. Vegetation consists of spirea (Spiraea douglasii, FACW), salmonberry (Rubus spectabilis, FAC+), scouler willow (Salix scouleriana, FAC), reedcanary grass (Phalaris arundinacea, FACW), and slough sedge (Carex obnupta, OBL). The overstory in wetland areas is comprised of red alder (Alnus rubra, FAC) with lesser amounts of Oregon Ash (Fraxinus latifolia, FACW) and cascara (Rhamnus purshiana, FAC-). Within the wetland, more than 50 percent of the dominant species were PO Rix 2R54 Relfair.Washington 9852R-Cell Phone 360-620-061 R-Office Phone 360-372-2421-hoad40(a�neonlenc_com Strange Wetland Delineation TWC07W319 February 15,2007 Page 5 of 8 identified as facultative (FAC) or wetter; and therefore meet the wetland criteria for hydrophytic vegetation. The upland vegetation was distinct from the wetland vegetation, with the exception of salmonberry (Rubus spectabilis, FAC), which extended beyond the wetland boundary. The upland vegetation within the parcel consists of an overstory of Douglas fir (Pseudotsuga menziesii, FACU) and Pacific madrone (Arbutus menziesii, UPL) with lesser amounts of red alder (Alnus rubra, FAC). The understory in upland areas is comprised of salal (Gaultheria shallon, FACU+), evergreen huckleberry (Vaccinium ovatum, UPL), ocean spray (Holodiscus discolor, UPL), sword fern (Polystichum munitum, FACU), and red elderberry (Sambucus racemosa, FACU). Less than 50 percent of the dominant species in this area were identified as facultative (FAC) or wetter, and therefore do not meet the criteria for hydrophytic vegetation (Appendix A). WETLAND EVALUATION RESULTS Wetland Categorization The wetland was classified as a Depressional wetland per Washington State Wetland Rating System for Western Washington (Hruby 2004). Based on functional attributes associated with the wetland including habitat, water quality, and hydrology functions, it has been rated as a Category II wetland, scoring 56 points on the state rating form, scoring 20 points for habitat function (see Appendix C for rating form). According to Table 17.01.070 B of the Mason County Resource Ordinance, the width for this Category II wetland for Moderate Impact Land Use is 110 feet with an associated 15-foot building setback. Moderate Impact Land Use is defined in Table 17.01.070 B of the Mason County Resource Ordinance as Single-family residential lots. The I I0-foot buffer from the wetland boundary has been staked in the field with metal stakes flagged with pink ribbon. SUMMARY This wetland report documents the presence of a depressional wetland at parcel #321347590213 located at 700 East Catfish Lake Road in Shelton, Mason County, Washington. The property is owned by Alan Strange. This wetland meets Mason County's wetland classification criteria for a Category II wetland with a moderate level of function for habitat. For Moderate Impact Land Use, Category II wetlands with a moderate level of function for habitat require a buffer of 110 feet with an associated 15-foot building setback. Moderate Impact Land Use is described in the Mason County Resource Ordinance as all single-family residential lots. It is recommended that all future site work take place outside of this protective buffer. Thank you for choosing the Wetland Corps as your environmental consultant.

NOTES: Revised 4/97 APPENDIX B: SOIL SURVEY TEXT ALDERWOOD SERIES The Alderwood series consists of brown, well-drained, upland soils. They have developed from mixed gravelly glacial till dominated by acid igneous rock. The imbedded gravel is mainly granite and quartzite. Rainfall is 45 to 60 inches a year. The native vegetation is a dense forest consisting almost entirely of Douglas-fir and a dense understory of salal, Oregon-grape, vine maple, and huckleberry. Northeast of the Hood Canal the understory is mainly rhododendron. Alderwood soils occupy the extensive rolling glacial moraines, and they are the dominant soils in the eastern part of the county. The Alderwood soils are associated with the somewhat excessively drained Everett and Indianola soils and with the moderately well drained Kitsap soils. Shelton and Hoodsport soils differ from the Alderwood soils in that they have developed under high rainfall and from glacial till having a much higher content of basic igneous rock. The Shelton and Hoodsport soils are more reddish throughout the profile. The Shelton soils are usually deeper to the cemented till than the Alderwood soils. Alderwood gravelly sandy loam, 5 to 15 percent slopes (Ab).-This is the most extensive, soil of the Alderwood series. It occupies undulating to rolling moraines. In undisturbed areas a 1- to 2-inch mat of very dark brown, acid organic matter is on the surface. This grades to a thin, dark grayish-brown,highly organic mineral soil. The surface soil consists of a friable,brown,medium acid gravelly sandy loam 8 to 13 inches deep. It has a weak granular structure and contains numerous rounded shot. Below the surface soil, to depths ranging from 18 to 24 inches, is a pale-brown gravelly sandy loam that is very friable, is single grained; and contains small to moderate amounts of shot . Between this layer and the cemented till is a 3- to 10-inch layer of very pale brown gravelly sandy loam. It contains no shot and is firmer but has the same texture as the layer above. However, it is faintly to distinctly spotted and horizontally streaked with brown and yellow. The cemented till consists of light-gray, gravelly sandy loam, and it normally occurs at depths ranging from 24 to 32 inches. It is impermeable to roots and very slowly permeable to water. The first few inches is usually laminated and streaked with reddish brown and yellow. Below this, to a depth of many feet, the till is uniformly cemented, fairly uniform light gray, and medium to strongly acid. A thin mat of roots often lies over the till. The cemented substratum tends to restrict the rapid downward movement of moisture. Use and suitability.-Not more than about 5 percent of this soil has been cleared and is used for crops or pasture. Most of the cultivated acreage is near the inlets of Puget Sound in the vicinities of Arcadia and Allyn. In this area the Alderwood soils are associated with the better agricultural soils of the Cloquallum, Sinclair and Kitsap series. Hay, small grains, pasture, fruits, nuts, grapes, and berries are the principal crops grown on the Alderwood soils. The lack of subsoil moisture damages crops in summer. For this reason, early maturing, short-season crops are suited best to this soil. Yields of all crops are usually fairly low because of low fertility and the dry summers. Pastures produce good forage in spring and late in fall if proper plants are used and management is good. The deeper soils are suited best to fruits, nuts, and grapes. The uncleared and remote areas are better suited to forestry than to cultivated crops. Nearly all the uncleared acreage is in second-growth forest 70 to 80 years of age. Shallowness to the compact till often inhibits growth of the older trees. The soil, however, is well suited to production of Christmas trees. Douglas-fir readily restocks in thick stands containing trees of good form. Stands of small trees are often thinned and pruned to maintain good form of growth. The growing of Christmas trees has expanded rapidly in the past few years and is now one of the important industries in the county. It is one of the PO Rox 2854 Relfair.Washington 99528•Cell Phone 360-620-061 R•Office Phone 360-372-2421 •hoad40nneonlenc.com proper uses of the cutover lands that are not in a high site class. Alder-wood soils need barnyard manure, green manure, nitrogen, or legumes to maintain a fertility for crop production. Phosphate fertilizers and green manure or barnyard manure greatly improve fertility. Nitrogen fertilizer is often applied with barnyard manure or when cover crops are plowed under. The fertilizer furnishes additional nitrogen needed to hasten decay of the organic matter. This soil is in capability subclass VIs and in site classes 4 and 5 for Douglas-fir. Small areas along- the border, where the soil is more than 32inches deep to compact till, are in site classes 3 and 4 for Douglas-fir. The McMurray series consists of peat that is made up largely of the partly decomposed remains of evergreen and decidious trees and of various shrubs that have accumulated in swampy basins, depressions, and low intermittent lakes. Uncleared areas are covered by a dense forest of cedar, spruce, fir, hemlock, alder, maple, vine maple, devilsclub, salal, bracken fern, and occasional areas of skunkcabbage, sedges, and reeds. The McMurray soils are saturated and must be drained before they can be used. Of the peats in Mason County, the McMurray peat is the least acid and the most fertile and desirable for crops. The McMurray soils occur as small areas scattered throughout the county. McMurray peat, 0 to 2 percent slopes (Me).-The upper 8 to 16 inches consists of coarse, woody, dark-brown peat containing many fragments of decaying wood. It is granular and friable. Below this layer the material is less decomposed and consists of brown, fibrous, sedimentary peat. At variable depths below 3 feet, the peat rests on a, saturated substratum of partly compact sand and gravel intermixed with silt, clay, and colloidal peat. The gravelly substratum may be many feet deep, but it is commonly within 3 to 5 feet of the surface. This soil is medium acid, saturated most of the year, and difficult to drain. It generally occurs in small isolated tracts in association with the fair and poor soils of the uplands. Use and suitability.-This is the most fertile and productive organic soil in Mason County. Only a small acreage is an cultivation, and it is used mainly for pasture and hay. However, it is suitable for small grains and truck crops. This soil will produce good yields of many crops if it is cleared and adequately drained and the water table is lowered. Isolated locations and high costs of clearing and draining prevent greater use for agriculture. The soil is in capability subclass IIIw.

For example,the wetland has been identified in the Shoreline Master Program,the Critical Areas Ordinance, or X in a local management plan as having special significance. To complete the next part of the data sheet you will need to determine the Hydro eg omorphic Class of the wetland being rated. The hydrogeomorphic classification groups wetlands in to those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands. Classification of Vegetated Wetlands for Western Washington Wetland Name: Strange Wetland Date: 2/15/07 1. Are the water levels in the wetland usually controlled by tides(i.e. except during floods)? NO—go to 2 YES—the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt(parts per thousand)? YES—Freshwater Tidal Fringe NO—Saltwater Tidal Fringe(Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is a Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were call estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions,the term"Estuarine"wetland is kept. Please note,however,that the characteristics that define Category I and II estuarine wetlands have changed(see p. ). 2. Is the topography within the wetland flat and precipitation is only source(>90%)of water to it. NO—go to 3 YES—The wetland class is Flats If your wetland can be classified as a"Flats" wetland, use the form for Depressional wetlands. 3. Does the wetland meet both of the following criteria? The vegetated part of the wetland is on the shores of a body of open water(without any vegetation on the surface)where at least 20 acres(8ha)are permanently inundated(ponded or flooded); At least 30%of the open water area is deeper than 6.6(2 m)? NO—go to 4 YES—The wetland class is Lake-fringe(Lacustrine Fringe) 4. Does the wetland meet all of the following criteria? The wetland is on a slope (slope can be very gradual). X The water flows through the wetland in one direction(unidirectional)and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. X The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually<3 ft diameter and less than 1 foot deep). NO—go to 5 YES—The wetland class is Slope 5. Is the wetland in a valley, or stream channel,where it gets inundated by overbank flooding from that stream or river? The flooding should occur at least once every two years, on the average,to answer"yes". The wetland can contain depressions that are filled with water when the river is not flooding. NO—go to 6 YES—The wetland class is Riverine 6. Is the wetland in a topographic depression in which water ponds, or is saturated to the surface, at some time of the year. This means that any outlet, if present is higher than the interior of the wetland. NO—go to 7 YES—The wetland class is Depressional 7. Is the wetland located in a very flat area with no obvious depressional and no stream or river running through it and providing water. The wetland seems to be maintained by high groundwater in the area. The wetland may be ditched,but has no obvious natural outlet. No—go to 8 YES—The wetland class is Depressional 8. Your wetland seems to be difficult to classify. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. Sometimes we find characteristics of several different hydrogeomorphic classes within one wetland boundary. Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10%or more of the total area of the wetland being rated. If the area of the second class is less than 10%classify the wetland using the first class. a�IGIrf.Classes'Wit�n:a�elaneateaT 1Fettand`I3ound` Crarss t©i�se m;R�rtin Slope+Riverine Riverine Slope+Depressional Depressional Slope+Lake-fringe Lake-fringe Depressional+Riverine along stream within boundary Depressional Depressional+Lake-fringe Depressional Salt Water Tidal Fringe and any other class of Treat as ESTUARINE under wetlands with special freshwater wetland characteristics If you are unable still to determine which of the above criteria apply to your wetland, or you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Old-growth forests: (Old growth west of Cascade Crest) Stands of at least 2 tree species, forming a T multi-layered canopy with occasional small openings,with at least 20 trees/ha(8 trees/acre)>81cm (32 in)dbh or>200 years of age. Mature forests: Stands with average diameters exceeding 53cm(21 in)dbh;crown cover may be less than 100%;decay, decadence,numbers of snags,and quantity of large downed material is generally less than that found in old-growth; 80—200 years old west of the Cascade Crest. Prairies: Relatively undisturbed areas(as indicated by dominance of native plants)where greases and/or forbs form the natural climax plant community. Talus: Homogenous areas of rock rubble ranging in average size 0.15—2.Om(0.5—6.5 ft), composed of basalt, andesite,and/or sedimentary rock,including riprap slides and mine tailings. May be associated with cliffs. Caves: A naturally occurring cavity,recess,void,or system of interconnected passages.

The salinity may be periodically increased above that of the open ocean by evaporation. Along some low-energy coastlines there is appreciable dilution of sea water. Estuarine habitat extends upstream and landward to where ocean-derived salts measure less than 0.5 ppt. during the period of average annual low flow. Includes both estuaries and lagoons. _ Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and may also include the backshore and adjacent components of the terrestrial landscape(e.g.,cliffs, snags,mature trees,dunes,meadows)that are important to shoreline associated fish and wildlife and that contribute to shoreline function(e.g., sand/rock/log recruitment,nutrient contribution,erosion control).

Wetland Type—Checkoff any criteria that apply to the wetland. Circle the Category when the appropriate criteria are met: Cl Estuarine wetlands?(see p.87) Does the wetland meet the following criteria for Estuarine wetlands? The dominant water regime is tidal, Vegetated,and With a salinity greater than 0.5 ppt. YES =Go to SC 1.1 NO X SC 1.1 Is the wetland within a National Wildlife Refuge,National Park,National Estuary Reserve,Natural Area Preserve, State Park or Educational,Environmental,or Scientific Reserve designated under WAC 332- Cat. 1 30-151?

YES =Category I NO=Category II Cat.I The wetland is relatively undisturbed(has no diking,ditching,filling,cultivation,grazing,and has Iess than 10%cover of non-native plant species. If the non-native Spartina spp,.are only species that cover more than 10%of the wetland,then the wetland should be given a dual rating(UII). Cat. II The area of Spartina would be rated a Category II while the relatively undisturbed upper marsh with native species would be a Category 1. Do not,however,exclude the area of Spartina in determining the size threshold of 1 acre. Dual At least 3/4 of the landward edge of the wetland has a 100 ft.buffer of shrub,forest,or un-grazed Rating or un-mowed grassland I/II The wetland has at least 2 of the following features: tidal channels,depressions with open water, or contiguous freshwater wetlands. C2 Natural Heritage Wetlands(see p. 88) 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 site YES Contact WNHP/DNR(see p. 88)and go to SC 2.2 NO X SC 2.2 Has DNR identified the wetland as a high quality undisturbed wetland or as a site with state threatened or endangered plant species? Cat I YES =Category 1 NO X C3 Boas(see p. 88) Does the wetland(or part of the wetland)meet both the criteria for soils and vegetation in bogs? Use the key below to identify if the wetland is a bog. If you answer yes you will still need to rate the wetland based on its function. 1. Does the wetland have organic soil horizons(i.e. layers of organic soil),either peats or mucks,that compose 16 inches or more of the first 32 inches of soil profile? (See Appendix B for a field key to identify organic soils)? YES=go to question 3 NO=go to question 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 a lake or pond? YES=go to question 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 of species in Table 3)? YES=Is a bog for purpose of rating NO=go to question 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 hold 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. 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)? Cat.I YES=Category I NO=Is not a bog for purpose of rating C4 Forested Wetlands (seep. 96) Does the wetland have at least 1 acre of forest that meet one of these criteria for the Department of Fish and Wildlife's forests as priority habitats?. If you answer yes you will still need to rate the wetland based on its function. Old-growth forests: (west of Cascade Crest) Stands of at least two three species forming a multi-layered canopy with occasional small openings;with at least 8 trees/acre(20 trees/hectare) that are at least 200 years of age OR have a diameter at breast height(dbh)of 32 inches(81 cm or more). NOTE: The criterion for dbh is based on measurements for upland forests. Two-hundred year old trees in wetlands will often have a smaller dbh because their growth rates are often slower. The DFW criterion is and"OR"so old-growth forests do not necessarily have to have trees of this diameter. _ Mature forests: (west of the Cascade Crest) Stands where the largest trees are 80—200 years old OR have an average diameters(dbh)exceeding 21 inches(53 cm);crown cover may be less than 100%;decay,decadence,numbers of snags,and quantity of large downed material is generally less than that found in old-growth.
