Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Common Deerweed Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This low shrubland is a disturbance-induced community that occurs on ground damaged by clearing or fire. It tends to occur in small (<1 acre, often much less) patches. It likely occurs throughout California but has been documented only in central and southern California. A small "weedy" community, it is easily overlooked. Stands occur on somewhat steep slopes to flat areas on variable aspects, most often southerly. Elevations range from 25 to 1043 m (84-3422 feet). Stands are often located on variable topography, sometimes lower to middle slopes. Soils are variable, including sands, clays, and loams. The low-shrub layer is dominated by Lotus scoparius var. scoparius. Artemisia californica, Eriogonum fasciculatum, Rhus ovata, Lupinus albifrons var. albifrons, and Corethrogyne filaginifolia may be present at low cover. The herbaceous layer is diverse and often includes non-native species, such as Aira caryophyllea, Artemisia dracunculus, Avena barbata, Bromus arenarius, Bromus hordeaceus, Bromus rubens, Centaurea melitensis, Erodium spp., Hirschfeldia incana, Silene gallica, and Vulpia myuros, and native species, such as Chaenactis glabriuscula, Croton californicus, Cuscuta californica, Eriogonum elegans, Lupinus bicolor, Nemacladus gracilis, Trifolium microcephalum, and Trifolium willdenovii.

Floristics: Lotus scoparius is dominant with intermittent to clumpy shrub cover (15-35% cover). Total vegetative cover is generally low (8-75%, a mean of 32%). Artemisia californica, Eriogonum fasciculatum, Rhus ovata, Lupinus albifrons var. albifrons, and Corethrogyne filaginifolia (= Lessingia filaginifolia) may be present at low cover. The herbaceous layer is diverse and often includes non-native species, such as Aira caryophyllea, Artemisia dracunculus, Avena barbata, Bromus arenarius, Bromus hordeaceus, Bromus rubens (= Bromus madritensis ssp. rubens), Centaurea melitensis, Erodium spp., Hirschfeldia incana, Silene gallica, and Vulpia myuros, and native species, such as Chaenactis glabriuscula, Croton californicus, Cuscuta californica, Eriogonum elegans, Lupinus bicolor, Nemacladus gracilis, Trifolium microcephalum, and Trifolium willdenovii.
