Name: Juniperus occidentalis / Artemisia arbuscula / Poa secunda Wooded Grassland
Reference: NatureServe Biotics 2019
Description: This association is known from the central Blue and Ochoco mountains, and from the Steens Mountains in the northern Great Basin. It occurs in shallow scablands where sufficient moisture and basalt cracks allow for the establishment of <i>Juniperus occidentalis</i>. Slopes are generally fairly flat (2-15%) at elevations of 1220 to 1770 m (4000-5800 feet). Soils are usually of igneous parent material (lava) of a sandy loam to loamy character. This is a savanna-like assemblage with <i>Juniperus occidentalis</i> occurring in open stands (less than 5% cover). <i>Artemisia arbuscula</i> cover is about 7-22%. Individual plants of this species are often concealed by surrounding bunchgrasses. <i>Poa secunda</i> ranges between 4-20% cover, while <i>Festuca idahoensis</i> and <i>Pseudoroegneria spicata</i> range 0-40% and 0-50%, respectively. <i>Poa secunda</i> gains importance at lower slopes with concave topography and with heavy grazing.
