Description:
This is a rocky bald or cliff community dominated by mixed forbs and bunch grasses. 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 Range, 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 3-10% cover of Lomatium martindalei, 1-20% cover of Selaginella wallacei, and 1-5% cover of moss. Sites have a very low but consistent cover of perennial grasses including Festuca rubra along the ocean, and Festuca roemeri (= Festuca idahoensis var. roemeri) in Oregon's western interior valleys, and Festuca idahoensis (= var. idahoensis) in the Cascades, in addition to Poa secunda, Koeleria macrantha, Danthonia californica, and Agrostis pallens (= Agrostis diegoensis). Forbs vary in the different areas, but Lewisia columbiana var. rupicola, Sedum spathulifolium, Saxifraga bronchialis, Allium cernuum, Lupinus lepidus, and Agoseris heterophylla are the most important. Endemic plants including Saxifraga hitchcockiana, Cardamine pattersonii, Dodecatheon austrofrigidum, Erythronium oregonum and Castilleja chambersii [sp. nov. ined.] are found primarily in this community.
