Name: Puccinellia lemmonii - Poa secunda Wet Meadow Reference: NatureServe Biotics 2019 Description: This is a valley bottom, semi-alkaline grassland known from the Klamath Basin in south-central Oregon, and from the Baker Valley in northeastern Oregon. As a valley bottom type, it is always found on flat, deep soil areas, usually of alluvial or pluvial origin, between 760-1220 m (2500-4000 feet) in elevation. It usually occurs along the edges of lakes, backwater oxbows or large wetlands, in valleys that have moderately alkaline soils. <i>Puccinellia lemmonii</i> and <i>Poa secunda</i> dominate these grasslands. <i>Hordeum jubatum</i> is often present, and occasionally codominant, along with <i>Elymus elymoides</i> and <i>Juncus</i> species. Forbs (<i>Castilleja pilosa, Erigeron filifolius, Astragalus purshii, Astragalus applegatei</i>) and bare ground provide a significant part of the overall cover. In addition, all known sites had some (between 1-5%) cover of <i>Ericameria nauseosa</i>, although this is assumed to be an artifact of historic grazing. At the wetter end, this type grades into <i>Deschampsia cespitosa</i> or <i>Carex</i> wetlands, and at the drier end into playa, or more commonly sagebrush habitats.  Accession Code: urn:lsid:vegbank.org:commConcept:30567-{31A19530-1DAE-46F1-88C1-764AC29A8376} Plot-observations of this Community Concept: 0
