Name: Pinus ponderosa / Carex geyeri Woodland
Reference: Western Ecology Working Group of...
Description: This <i>Pinus ponderosa</i> / sedge woodland occurs in mountainous areas of the western United States from 1875 to 2610 m (6150-8560 feet) in elevation. It occurs on gentle to moderately steep slopes (10-25%) with variable aspect. Soils are generally moderately deep sandy loams or rocky loams. Canopy cover is strongly dominated by <i>Pinus ponderosa</i>. <i>Pseudotsuga menziesii</i> and <i>Juniperus</i> spp. are common associates. Shrubs are variable and tend to be sparse but commonly include <i>Mahonia repens, Symphoricarpos oreophilus</i>, and <i>Juniperus communis</i>, with <i>Quercus gambelii, Amelanchier alnifolia</i>, and <i>Arctostaphylos uva-ursi</i> as occasional associates. The herbaceous layer is well-developed and dominated by <i>Carex geyeri</i> (10-60%). Additional graminoids that occur with lower cover include <i>Leucopoa kingii, Pseudoroegneria spicata, Poa nervosa</i>, and <i>Koeleria macrantha</i>, among others. Forbs are often uncommon but can include <i>Campanula rotundifolia, Crepis acuminata, Potentilla fissa (= Drymocallis fissa), Antennaria rosea</i>, and <i> Achillea millefolium var. occidentalis (= Achillea lanulosa)</i>, when present. Unvegetated surface is common in these stands and is comprised of dense needle duff.
