Name: Pinus monticola / Deschampsia caespitosa Forest Reference: Western Ecology Working Group of... Description: This is an extremely rare floodplain forest from central Oregon. It is known from only one site in the upper parts of the John Day River watershed. The elevation is about 1525 m (5000 feet), in the grand fir zone. It is a floodplain community, found in a broad and shallow, slightly sinuous river valley, in a narrow, V-shaped valley with moderate gradient (over 2%). Fire and flooding disturbance help maintain <i>Pinus monticola</i> as the primary canopy dominant. <i>Pinus monticola</i> is the sole canopy dominant. <i>Abies grandis</i> and <i>Pinus monticola</i> are both present as understory trees. <i>Mahonia repens</i> was the only shrub found, at very low cover. Grasses dominate the understory, with <i>Deschampsia caespitosa</i> (13% cover) and <i>Elymus glaucus</i> (10% cover) being codominant, and <i>Carex geyeri</i> also present. Forbs included <i>Achillea millefolium, Adiantum pedatum</i>, and <i>Orthilia secunda (= Pyrola secunda)</i>.  Accession Code: VB.CC.32809.CEGL003441 Plot-observations of this Community Concept: 0
