Forested wetland is a wetland or homogeneous stand within a wetland complex whose upper layer of 

 vegetation consists of trees with a canopy coverage of 30^ or more (adapted from Cowardin et. al. 

 1979). For the purposes of this rating system, a mature forested wetland is a forested wetland with an 

 ovcrstory dominated by mature trees having a wetland indicator status of facultative (FAC), 

 facultative-wet (FACW), or obligate wetland (OBL) (Reed, 1988) and with more than one age 

 class/size present. Mature trees are considered to be trees that are over 50 years old for hardwood 

 species. The prescence of young trees of the dominant overstory species is an indicator of long-term 

 persistence on the site. 



Hydrologically isolated wetland means those regulated wetlands which 1) have no surface water 

 connection to a lake, river or stream; 2) are outside of and not contiguous to any lOO-yr floodplain of a 

 lake, river, or stream; and 3) have no contiguous hydric soil between the wetland and any surface water. 



Peat Wetlands means wetlands ith undrained hydric organic soils. 



Plant Association means climax stands of vegetation in which the dominant sp)ecies of corresponding f^ 



layers are essentially the same, to the extent that any differences in composition are due to chance 

 dissemination rather than to a fundamental dissimilarity in habitat potential. 



Priority Habitat : A seasonal range or habitat clement with which a given species has a primary 

 association, and which, if altered, may reduce the likelihood that the spiccies will maintain or 

 increase population over the long term. These might include areas of high relative density, breeding 

 habitat, winter range, and movement corridors. Priority habitats might also include areas that are of 

 limited availability or high vulnerability to alteration, such as cliffs, talus, wetlands, etc. 



Priority Species : Animal species that are of concern due to their |x>pulation status and their sensitivity 

 to habitat manipulation. Priority species include species of concern, monitor species, priority game 

 species, as well as other game and nongame species. 



Species of Concern : are those animal species that are listed or candidates for designation as 

 Endangered, Threatened, or Sensitive by the Washington Department of Wildlife. 



State Endangered Species arc those that are seriously threatened with extirpation throughout all or a 

 significant portion of their range within Washington. 



State Monitor Species : Those animal and plant sjxxries of special interest because they: 1) have 

 significant popular appeal; 2) require limited habitat during sonr>e portion of their life cycle; 3) are 

 indicators of environmental quality; 4) require further field investigations to determine population 

 status: 5) have unresolved taxononnic problems that may bear upon status classification; or 6) were 

 justifiably removed from Endangered, Threatened, or Sensitive status.
