CEGL005745 Chilopsis linearis / Prunus fasciculata Desert Wash Scrub

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Desert-willow / Desert Almond Desert Wash Scrub

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This association occurs along intermittently flooded drainages in the Mojave Desert in California. Chilopsis linearis is dominant and characteristic in the sparse to open tree overstory (2-17% cover). The sparse to moderately dense shrub layer is variable, ranging from 5 to 33% cover, and is dominated or codominated by Prunus fasciculata with other wash-associated species such as Acacia greggii, Hymenoclea salsola, and Viguiera parishii, which often have around 5% cover. A variety of other shrubs may be present. If present, the herb understory is typically sparse and ranges from 1 to 10% cover. Commonly associated herbs include Euphorbia sp., Oenothera caespitosa, Penstemon palmeri, Sphaeralcea ambigua, and on disturbed sites introduced species Bromus madritensis, Bromus rubens, Erodium cicutarium, and Schismus spp. Stands are found at low to mid elevations along intermittently flooded canyon drainages and gravelly arroyos that are within midslope to upper bajada positions with northwestern to eastern aspects. Sites occur on low to mid slopes between 970 and 1380 m elevation often with southerly aspects. Soils are rapidly drained medium to coarse sand derived from sedimentary rocks, primarily limestone and sandstone and a variety of igneous and metamorphic substrates such as gneiss, granite, granodiorite, and schist.

Floristics: This scrub is dominated by characteristic species Chilopsis linearis in the sparse to open tree overstory (2-17% cover) (Keeler-Wolf et al. 1998a, Evens 2000, Evens et al. 2014). The sparse to moderately dense shrub layer is variable, ranging from 5 to 33% cover, and is dominated or codominated by Prunus fasciculata with other wash-associated species such as Acacia greggii, Hymenoclea salsola, and Viguiera parishii, which often have around 5% cover (Keeler-Wolf et al. 1998a, Evens 2000, Evens et al. 2014). A variety of other shrubs may be present, including Ambrosia eriocentra, Artemisia ludoviciana, Cylindropuntia acanthocarpa, Gutierrezia sarothrae, Opuntia phaeacantha, Phoradendron californicum, Salazaria mexicana, Salvia dorrii, Stephanomeria pauciflora, Yucca baccata, and Yucca schidigera (Keeler-Wolf et al. 1998a, Evens 2000, Evens et al. 2014). If present, the herb understory is typically sparse and ranges from 1 to 10% cover. Commonly associated herbs include Euphorbia sp., Oenothera caespitosa, Penstemon palmeri, Sphaeralcea ambigua, and on disturbed sites introduced species Bromus madritensis, Bromus rubens, Erodium cicutarium, and Schismus spp. (Keeler-Wolf et al. 1998a, Evens 2000, Evens et al. 2014).
