Name: Achnatherum lemmonii / Racomitrium canescens Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: The bunchgrass <i>Achnatherum lemmonii (= Stipa lemmonii)</i> and the moss <i>Racomitrium canescens</i> dominate this sparse, bunchgrass association found on hilltop balds along valley margins. Cover values are not available, but frequency in 0.01 square meter plots show <i>Achnatherum</i> from 15-56% and <i>Racomitrium</i> from (74-100%). Other native bunchgrasses include <i>Festuca idahoensis</i> and <i>Koeleria macrantha</i>. <i>Quercus garryana</i> trees are usually found on the margins of this type, but most areas are two shallow soiled to support much tree or shrub growth. <i>Toxicodendron diversilobum</i> is found under the isolated trees, and on the margins of these grasslands. Native forbs from this grass bald include <i>Trifolium microcephalum, Viola douglasii, Lotus micranthus, Allium amplectens</i>, and <i>Eriogonum nudum</i>. Exotic grasses which invaded the sites include <i>Aira caryophyllea, Bromus hordeaceus (= Bromus mollis), Bromus rigidus, Cynosurus echinatus, Holcus lanatus</i>, and <i>Arrhenatherum elatius</i>.
