A4101 Ericameria linearifolia - Cleome isomeris Scrub Alliance
Type Concept Sentence: This alliance includes shrublands dominated by Ericameria linearifolia, Eastwoodia elegans, and Cleome isomeris. They occur on gentle to steep disturbed hillslopes in central and southern California''s inner Coast Ranges and Sierra Nevada foothills.
Common (Translated Scientific) Name: Narrowleaf Goldenbush - Bladderpod Spiderflower Scrub Alliance
Colloquial Name: Narrowleaf Goldenbush - Bladderpod Spiderflower Scrub
Hierarchy Level: Alliance
Type Concept: This shrubland alliance includes Ericameria linearifolia, Eastwoodia elegans, and Cleome isomeris as dominant shrubs. Stands occur in semi-desert environments of central and southern California''s inner Coast Ranges and Sierra Nevada foothills where rainfall is unpredictable. They occur below 1000 m (3300 feet) in elevation on gentle to steep hillslopes that are often north-facing. Soils are rocky gravels to loams and clay loams. Sites are areas that have experienced recent disturbance such as fire, grazing, or colluvial movement. Shrubs quickly form a seedbank in soil and duff within the first two years of germination and fluctuate with other seral scrub, semi-desert scrub, and herbaceous vegetation types.
Diagnostic Characteristics: Ericameria linearifolia, Eastwoodia elegans, and Cleome isomeris as dominant or codominant shrubs.

Floristics: This shrubland alliance includes Ericameria linearifolia, Eastwoodia elegans, and Cleome isomeris (= Isomeris arborea) as dominant shrubs.
Dynamics: This alliance appears on sites with recent disturbance from fire, grazing, or colluvial movement. Shrubs quickly form a seedbank in soil and duff within the first two years of germination and compete with other seral scrub, semi-desert scrub, and herbaceous vegetation types.
Environmental Description: Stands occur below 1000 m (3300 feet) in elevation on gentle to steep hillslopes that are often north-facing. Soils are rocky gravels to loams and clay loams. Sites are areas that have experienced recent disturbance such as fire, grazing, or colluvial movement.
Geographic Range: This alliance is found on California''s southern and central Coast Ranges, usually inland along the foothills of the ranges, and into the southern Sierra Nevada foothills from below Mount Pinos into the Tehachapi Mountains, into the western and southern Mojave Desert, and extending south into Baja California, Mexico.
