Common (Translated Scientific) Name: Ripgut Brome - Soft Brome - Clover species - American Wild Carrot Ruderal Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This herbaceous association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands of this herbaceous vegetation are found at low elevations (520-610 m [1700-2000 feet]) on the midslope of southeast- to west-facing, somewhat steep to steep (17-29°), concave, undulating and linear slopes. Soils are somewhat poorly drained to well-drained with textures ranging from loam to clay loam from metamorphic, schist and gneiss parent material. Litter ranges from 60-96% cover. Disturbance from invasion of exotics is common and impact levels are low to high. This association often forms a continuous, sometimes open, herbaceous layer dominated by Trifolium microcephalum, Daucus sp., Bromus hordeaceus, and Galium parisiense. Daucus pusillus, Clarkia purpurea, and Hypochaeris glabra are also present. Centaurea solstitialis and Lotus unifoliolatus var. unifoliolatus can be common at many sites. Lessingia leptoclada, Bromus arenarius, Trifolium ciliolatum, Lupinus bicolor, Lactuca serriola, and Thysanocarpus curvipes are often found in this association. A variety of other species may be found contributing to minor cover and often include Avena barbata, Bromus diandrus, Calandrinia ciliata, Castilleja densiflora, Croton setigerus, Silene gallica, Stephanomeria virgata, Torilis arvensis, and Vulpia myuros.
