It has been identified as a cell need (or elements) in the Blue Mountains for several vegetation types: 1) mid-elevation ponds with aquatic beds and marshy shore; 2) grandfir/ twinflower; 3) grand fir/ big huckleberry; and 4) grand fir-Pacific yew. In addition to the mesic grand fir plant associations, this complex also contains, Douglas-fir/ pinegrass, Douglasfir/ ninebark, ninebark-snowberry plant associations common to the mesic forests in the Blue Mountains physiographic province. Establishment record and designation order formally establish the area, which fulfills an RNA need for a mesic grand fir-dominated forest type in the Blue Mountains.1348059 bytesapplication/pdfen-USForest management -- Umatilla National Forest (Or. and Wash.)Research natural areas -- OregonEnvironmental monitoring -- Umatilla National Forest (Or. and Wash.)Other
