Reference: EcoArt 2002
Description: In Oregon, this is a somewhat common scabland alliance found from roughly 300-1670 m in elevation. It occurs on barren, fairly young basalts or shallow loams over basalt. Sites include ridgetops and steeper sites with rock outcrops. Extreme topo-edaphic drought is the major process influencing these communities. The alliance is often in a mosaic with ~Pseudoroegneria spicata$ canyon grassland or shrub steppe communities, but occasionally is found in ~Juniperus$ woodlands or ~Pinus ponderosa$ forests. ~Salvia dorrii$ is the dominant shrub, but cover or abundance information is not available. ~Poa secunda$ and ~Pseudoroegneria spicata$ are the dominant grasses, making up most of the herbaceous cover. ~Danthonia unispicata$ and ~Achnatherum hendersonii (= Stipa hendersonii)$ are occasionally important. Forb species can include ~Physaria oregona, Lewisia rediviva, Trifolium macrocephalum, Viola trinervata$, and species of ~Lomatium, Collomia, Erigeron$, and ~Arenaria$, all early blooming species. Many forb species are largely restricted to these environments. Information from California must be reviewed for inclusion in this description.
