Description:
This is a rocky bald or cliff community dominated by mixed forbs and bunchgrasses. These habitats are found from low elevations in the western Oregon valley margins, and on coastal bluffs just above the ocean. Elevation ranges from 15-460 m (50-1500 feet). Stands are also found on higher elevation peaks in the Oregon Coast Ranges, on localized balds, usually at elevations of 820-1040 m (2700-3400 feet). In the Coast Range, it is most common on west-facing aspects, but can also occur on south- and southeast-facing slopes, ranging from 5-30%. It is rarely found on north slopes, which are forested. Soils are thin to non-existent, generally on basalt or gabbros. The association was originally described as a rock garden community, but is characterized by low cover of <i>Lomatium martindalei, Selaginella wallacei</i>, and mosses. Sites have a very low but consistent cover of perennial grasses including <i>Festuca rubra, Festuca idahoensis ssp. roemeri</i>, and <i>Festuca idahoensis ssp. idahoensis</i>, in addition to <i>Poa secunda, Koeleria macrantha, Danthonia californica</i>, and <i>Agrostis pallens</i>. Forbs vary in the different areas, but <i>Lewisia columbiana var. rupicola, Sedum spathulifolium, Saxifraga bronchialis, Allium cernuum, Lupinus lepidus</i>, and <i>Agoseris heterophylla</i> are the most important. Endemic plants, including <i>Saxifraga hitchcockiana, Cardamine pattersonii, Dodecatheon austrofrigidum, Erythronium oregonum</i> and <i>Castilleja chambersii</i>, are found primarily in this community.
