Name: Elymus lanceolatus - Hesperostipa comata Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This is an open, sandy grassland on flat, Columbia River plains. The topography is composed of very low (0.5 m) dunes and open sand comprises almost 50% of the cover. Elymus lanceolatus is a rhizomatous grass which binds the sand and occurs throughout the site, providing 10-15% cover. The bunchgrass Hesperostipa comata (= Stipa comata) occurs in areas that are marginally stabilized, but overall represents only about 1% cover. Achnatherum hymenoides (= Oryzopsis hymenoides) and Poa secunda occur at very low cover throughout the stand, as do some forbs: Astragalus sclerocarpus, Oenothera pallida, Achillea millefolium, and Phlox longifolia. Non-native species include Bromus tectorum, Centaurea diffusa, Sisymbrium altissimum, and Salsola kali.  Accession Code: VB.CC.20384.ELYMUSLANCEOLAT Plot-observations of this Community Concept: 0
