CEGL002704 Prunus fasciculata Shrubland

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Desert Almond Shrubland

Colloquial Name: Desert Almond Desert Wash

Hierarchy Level:  Association

Type Concept: This association is currently only described from Joshua Tree National Park, California. Additional global information will be added as it becomes available. Stands form an open to intermittent shrubland with 0-4% cover for the tree/tall stratum, 1-35% cover for the shrub/medium stratum, and 0-24% cover for the herb/low stratum. Total vegetative cover ranges from1-36%. This association is dominated by the shrub Prunus fasciculata and herb species Achnatherum speciosum. Yucca brevifolia often occurs at low cover in the tree layer. Shrub species often present are Hymenoclea salsola, Ephedra nevadensis, Eriogonum fasciculatum, Lycium cooperi, Salazaria mexicana, and Yucca schidigera. The exotic species Bromus rubens is often present in the herbaceous layer. Stands are found at mid to high elevations (900-1500 m [2900-5000 feet]) on flat to gentle slopes (0-3°). They occur in drainages of canyon bottoms, washes and adjacent bajadas that have fluvial disturbance, as well as rocky hills that have had fire disturbance. Microtopography varies and may be convex, linear, concave, or undulating. Soil textures typically are sandy, and soils are derived from granitic parent material. Ground cover is comprised of 0-35% bedrock, 0-20% boulder, 0-20% stone, 0-20% cobble, 0-62% gravel, and 9-94% fines cover. Litter cover is 0- 25%. These sites experience low to high levels of disturbance from competition from exotics.
