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 from 2195 to 2620 m (7200-8600 feet) elevation. Stands are on steep midslopes on loamy sands derived from granitic rocks. Aspects are northeast, east, and southeast. These stands tend to occur on the lee of ridges or concavities, perhaps where more snow accumulates than is the mode for the area. This association is characterized by a continuous canopy between 1-2 m in height. Ceanothus velutinus and Prunus emarginata are the dominant shrub species. Several other shrub species may be present at very low cover values. These include Symphoricarpos rotundifolius, Artemisia tridentata, Eriogonum umbellatum, and/or Eriogonum elatum. The herbaceous layer is diverse but sparse. Common herbaceous associates include Phacelia ramosissima, Crepis acuminata, Cryptantha echinella, Gayophytum ramosissimum, Lupinus argenteus, Monardella odoratissima, Wyethia mollis, and/or Osmorhiza occidentalis. Scattered graminoids are present at very low cover values and may include Elymus elymoides, Elymus trachycaulus, Achnatherum occidentale, Bromus carinatus, and/or Melica stricta. Most stands are known to respond to fire by prolific reseeding, in some cases emerging from a seedbank after many years. The local stands on the east side of the Sierra Crest are probably no less dependent on fire even though the surrounding Artemisia and Purshia scrubs are not fire-dependent. These local stands appear to favor mesic, snow-accumulating microsites where they are able to persist and form seedbanks from which they do spring forth after the occasional fires in the sagebrush zone.
