Description
Summary:All woody and succulent vegetation in the arid Alabama Hills region was sampled, using 24 0.07 ha plots regularly placed over an area of 80 km². Density and canopy volume were measured and the data treated by polar ordination. Intensity of grazing, geologic substrate, and topographic roughness were environmental features that correlated with local variation in the regional vegetation type. Overall, the vegetation is transitional between Great Basin sagebrush steppe and Mojave Desert creosote bush scrub. It is similar to the Grayia-Lycium community that has been described for (and thought to be restricted to) southern Nevada by Beatley (1975), except that Atriplex polycarpa, Eriogonum fasciculatum subsp. polifolium, and Haplopappus cooperi are additional codominants. The senior author anticipates repeated sampling on these permanently located plots every 5 years.
