TY - JOUR T1 - Distribution and conservation status of coastal sage scrub in southwestern California JF - Journal of Vegetation Science Y1 - 1994 A1 - Davis, F. W. A1 - Stine, P. A. A1 - Stoms, D. M. KW - gap analysis KW - information analyis KW - vegetation classification AB - A landscape-based characterization of vegetation has been developed for southwestern California using satellite imagery, air photos, existing vegetation maps, and field data. Distribution maps of nine dominant coastal scrub species and 13 species assemblages that were identified by divisive information analysis have been analyzed to quantify spatial patterns of species co-occurrence. Three general distribution patterns are identified that suggest the Diegan, Venturan and Riversidian Associations identified by other workers. Vegetation data have also been related to land ownership and management to assess the conservation status of upland plant communities. A large proportion of the mapped distribution of species and vegetation types is on private land, and several taxa show less than 4% of mapped distribution in nature reserves. The analysis highlights the need to extend current conservation planning efforts into the northern part of the region to encompass areas where Salvia leucophylla is a frequent community dominant.
