Name: Lomatium martindalei Herbaceous Alliance Reference: Western Ecology Working Group of... Description: The Lomatium martindalei Herbaceous Alliance (A.1647) occurs on some of the peaks of the Oregon Coast Ranges, ranging from 750-1250 m elevation. The peaks are composed of intrusive igneous bedrock and in scattered localities support areas of non-forested meadows, known as grass balds. These balds are small openings in areas otherwise heavily forested; implying presence of this alliance is due to an unusual combination of topo-edaphic factors. This alliance is found in these non-forested patches, adjacent to bedrock outcrops and restricted to shallow, rocky and well-drained soils. These herbaceous meadows are dominated by a mix of perennial forbs, such as Lomatium martindalei, Lupinus lepidus, and Agoseris heterophylla. Several grass species can also be common, including Koeleria macrantha and Aira praecox (introduced from Europe). The nonvascular layer is important in this alliance and is composed of mosses and, probably, lichens. Nonvascular species present are not known.  Accession Code: VB.CC.24541.LOMATIUMMARTIND Plot-observations of this Community Concept: 0
