Field guide for forested plant associations of the Wenatchee National Forest.

Abstract

A classification of forest vegetation is presented for the Wenatchee National Forest (NF). It is based on potential vegetation, with the plant association as the basic unit. The sample includes about 570 intensive plots and 840 reconnaissance plots distributed across the Wenatchee National Forest and the southwest portion of the Okanogan National Forest from 1975 through 1994. The hierarchical classification includes 10 forest series and 104 types (plant association or community type). Diagnostic keys and descriptions are presented for each tree series and type. Detailed descriptions are given for each type having at least five sample stands in the Wenatchee NF. Those descriptions include information about plant species occurrences, type distribution, environment and soils, potential timber productivity, management considerations, and relationships to other classifications. Brief descriptions are presented for miscellaneous types (those having fewer than five plots in the Wenatchee NF).
