A complex scrub, open enough to be passable, and usually characterized by Yucca brevifolia herbertii, Eriogonum fasciculatum polifolium, and Isomeris arborea. Most of the constituent species also occur in other nearby communities.
SITE FACTORS:
Very shallow, overly-drained, often rolling to steep soils, usually derived form granitic parent materials. These sites have extremely low water holding capacity, mild alkalinity, and are not very saline. Intergrades on deeper soils (with higher water holding capacity) or at cooler elevations with Great Basin Scrubs (35000), Blackbush Scrub (34300), or Pinyon Woodlands (72000); at warmer elevations with Creosote Bush Scrub (33100, 34100).
DISTRIBUTION:
Widely but erratically scattered along the eastern base of the Sierra Nevada from the southwestern Owens Valley southward along the Tehachapis, San Gabriel, San Bernardino, San Jacinto, and Peninsula ranges to northern Baja California. Typically occurs between 2000-5000 feet.
