<br />criterion that applies to the wetland is to be used in the rating. See terl for definition of
<br />"undisturbed"
<br />❑ 100 in (330tl) of relatively undisturbed vegetated areas, rocky areas, or open water >95%
<br />of circumference. No strictures are within the undisturbed part of buffer. (relatively
<br />undisturbed also means no -grazing, no landscaping, no daily human use) Points = 5

<br />i12.2 Corridors and Connections (seep. 81)
<br />H 2.2.1 is the wetland part of a relatively undisturbed and unbroken vegetated corridor
<br />(either riparian or upland) that is at least 150 ft wide, has at least 30% cover of shrubs, forest
<br />or native undisturbed prairie, that connects to estuaries, other wetlands or undisturbed
<br />uplands that are at least 250 acres in size? (dams in riparian corridors, heavily used gravel
<br />roads, paved roads, are considered breaks in the corridor).
<br />❑YES-4points (gotoH2.3) ❑NO=go toH2.2.2
<br />H 2.2.2 is the wetland part of a relatively undisturbed and unbroken vegetated corridor
<br />(either riparian or upland) that is at least 50ft wide, has at least 30% cover of shrubs or
<br />2
<br />forest, and connects to estuaries, other wetlands or undisturbed uplands that are at least 25
<br />acres in size? OR a Lake -fringe wetland, if it does not have an undisturbed corridor as in
<br />the question above?
<br />✓❑YES=2points (go toH2.3) ❑NO=H2.2.3
<br />H 2.2.3 is the wetland:
<br />❑ within 5 nti (8km) of a brackish or salt water estuary OR
<br />❑ within 3 mi of a large field or pasture (>40 acres) OR
<br />❑within 1 mi of a lake greater than 20 acres'?
<br />YES =1 point F7NO = 0 points

<br />H 2.3 Near or ad scent to other priority habitats listed by WDFW (seep. 82)
<br />Which of the following priority habitats are within 330R (I00m) of the wetland unit? NOTE- the
<br />connections do not have to be relatively undisturbed
<br />These arc DFW definitions. Check with your• local DFW biologist ifthere are any questions.
<br />❑Riparian: The area adjacent to aquatic systems with flowing water that contains elements of
<br />both aquatic and terrestrial ecosystems which mutually influence each other.
<br />Aspen Stands: Purc or mixed stands of aspen greater than 0.8 ha (2 acres).
<br />Cliffs: Greater than 7.6 in (25 ft) high and occurring below 5000 ft.
<br />Old -growth 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 20 trees/ha (8
<br />trees/acre) > 81 cm (32 in) dbh or> 200 years of age,
<br />❑Mature forests: Stands with average diameters exceeding 53 cm (21 in) dbh; crown cover
<br />may be less that 100%; crown cover may be less that 100%; decay, decadence, numbers of
<br />snags, and quantity of large downed material is generally less than that found in old -
<br />growth; 80 - 200 years old west of the Cascade crest.
<br />❑Prairies: Relatively undisturbed areas (as indicated by dominance of native plants) where
<br />grasses and/or forbs form the natural climax plant community.
<br />❑Talus: Homogenous areas of rock nibble ranging in average size 0.15 - 2.0 in (0.5 - 6.5 ft),
<br />composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine
<br />tailings. May be associated with cliffs.
<br />Caves: A naturally occurring cavity, recess, void, or system of interconnected passages
<br />Oregon white Oak: Woodlands Stands of pure oak or oak/conifer associations where
<br />canopy coverage of the oak component of the stand is 25%.
<br />❑Urban Natural Open Space: A priority species resides within or is adjacent to the upon
<br />space and uses it for breeding and/or regular feeding; and/or the open space functions as a
<br />corridor connecting other priority habitats, especially those that would otherwise be
<br />isolated; and/or the open space is an isolated remnant of natural habitat larger than 4 he (10
<br />acres) and is surrounded by urban development.
<br />❑Estuary/Estuary-like: Dccpwatcr tidal habitats and adjacent tidal wetlands, usually semi -
<br />enclosed by land but with open, partly obstructed or sporadic access to the open ocean, and
<br />in which ocean water is at least occasionally diluted by freshwater runoff from the laird.
<br />The salinity may be periodically increased above that of the open ocean by evaporation,
<br />Along some low -energy coastlines there is appreciable dilution of sea water. Estuarine
<br />habitat extends upstream and landward to where ocean -derived sails measure less than
<br />0.5ppt. during the period of average annual low flow. Includes both estuaries and lagoons,
<br />❑_Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of
<br />beaches, and may also include the backshorc and adjacent components of the terrestrial
<br />landscape (e.g., cliff's, snags, mature trees, duties, meadows) that are important to shoreline
<br />associated fish and wildlife and that contribute to shoreline function (e.g., sand/rockAog
<br />recruitment, nutrient contribution, erosion control).
<br />❑If wetland has 3 or more priority habitats = 4 points
<br />❑if wetland has 2 priority habitats = 3 points
<br />❑If wctland has I priority habitat = I point ❑✓ No habitats = 0 points
<br />Note: All vegetated wetlands are by definition a priority habitat but are not included in this
