Name: Sphaeromeria argentea - Artemisia frigida - Poa secunda Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: A low and sparsely vegetated appearance, similar to windswept tundra vegetation, is characteristic of this association, which is found in the mountains of central Idaho. This type occurs on alluvial fans at elevations from approximately 6200-6500 feet. These fans are a complex of interlayered materials consisting of boulders, cobbles, and pebbles mixed with sand, silt, and clay. The soils are highly variable, in some sites derived from sand and in others derived from clay. Most of the ground surface is covered by a cobble or boulder pavement, resulting from the removal of fine-grained materials by wind and surface runoff. The soils associated with this vegetation type occur on alluvial flats and are dry gravelly loams, with shallow rooting depths, and a windswept surface. Two of the dominant species, Sphaeromeria argentea (= Tanacetum nuttallii) and Artemisia frigida, are broad-leaved suffrutescent perennial forbs less than 0.5 m in height. Sphaeromeria is usually more abundant, but less conspicuous, than the Artemisia frigida. The perennial bunchgrass Poa secunda is common and usually less than 3 dm tall. Other forbs occurring include Phlox hoodii ssp. muscoides (= Phlox muscoides), Ionactis alpina (= Aster scopulorum), and Penstemon pumilus.  Accession Code: VB.CC.21894.SPHAEROMERIAARG Plot-observations of this Community Concept: 0
