CEGL003129 Holodiscus discolor / Sedum obtusatum ssp. boreale - Cryptogramma acrostichoides Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Oceanspray / Sierra Stonecrop - American Rockbrake Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands of this association are found on steep midslopes between 2500 and 3050 m (8200-10,000 feet) elevation. Aspects are east to south, and soils are silt loams to loamy sands derived from metamorphic or igneous parent material. This association forms an intermittent canopy between 0.5-5 m in height. Holodiscus discolor dominates the shrub canopy with small amounts of Linanthus pungens, Artemisia tridentata, and/or Artemisia rothrockii usually present. Cryptogramma acrostichoides and Sedum obtusatum are the diagnostic herbaceous species, though neither contributes more than 1.5% cover. Other common herbaceous species present at very low cover values may include Eriogonum nudum, Castilleja applegatei, Pellaea bridgesii, Penstemon newberryi, Achillea millefolium, and/or Streptanthus tortuosus. Several graminoid species provide traces of cover including Elymus elymoides, Achnatherum occidentale, Agrostis variabilis, and/or Juncus parryi.
