The vegetation in this alliance occurs in alpine and subalpine areas in high mountains of the Pacific Coast. Elevations range from 1700-2200 m. The climate is cold and snowy with severe winds, late-lying snow, and a short growing season. Annual precipitation ranges from over 250 cm near the Cascade crest to less than 100 cm farther east in the Cascades and in the Sierra Nevada of California. The vegetation typically occurs on concave snowbeds, which are well-drained. Snow melts by late July and soils dry thoroughly by late summer. Soils are composed of varied parent materials, including granitics, pumice, and basalt, with abundant coarse fragments. Plant associations in this alliance are dominated by ~Carex breweri$. Xeric graminoids are the most common associates and may codominate stands. ~Danthonia intermedia$ is especially important in the northeastern Cascades, and ~Poa nervosa$ becomes important in the Sierra Nevada alpine. Other graminoid associates include ~Carex scirpoidea ssp. pseudoscirpoidea, Carex nardina$, and ~Carex phaeocephala$. Forb associates include ~Lupinus sellulus var. lobbii, Erigeron aureus, Antennaria lanata$, and ~Solidago multiradiata$. Adjacent vegetation is usually parkland or krummholz composed of ~Tsuga mertensiana, Pinus albicaulis, Larix lyallii$, or ~Abies lasiocarpa$, dry alpine grasslands, sedge- or shrub-dominated wetlands, or bare rock and ice. |

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. |

This alliance is reported from the Upper Midwest region of the United States. Stands are dominated by tall sedges. ~Carex lacustris$ is the characteristic sedge. ^ |
