Name: Achnatherum lemmonii - Racomitrium ericoides Sparse Rock Vegetation Alliance
Reference: NatureServe Biotics 2019
Description: This alliance is characterized by sparse herbaceous- and nonvascular-dominated vegetation of the Klamath Mountains. Vegetative cover is dominated by forbs, grasses, mosses, or lichens. Total species cover typically does not exceed 10%. Typical species include <i>Achnatherum lemmonii, Achnatherum occidentale, Elymus elymoides, Sedum oregonense</i>, and <i>Racomitrium ericoides</i>. Scattered trees and shrubs are common. Sites include steep cliff faces, bald ridgetops and shoulder outcrops, narrow canyons, and smaller rock outcrops. Substrates consist of igneous, sedimentary, and metamorphic bedrock. Soil development is limited as is herbaceous cover.
