March 2008 Draft Vegetation Communities of San Diego County Introduction San Diego’s vegetation communities owe their diversity to the wide range of soil and climatic conditions found in the County. The County encompasses desert, mountainous and coastal conditions over a wide range of elevation, precipitation and temperature changes. These conditions provide niches for endemic species and a wide range of vegetation communities. San Diego County is home to over 200 plant and animal species that are federally listed as rare, endangered, or threatened. The preservation of this diversity of species and habitats is important for the health of ecosystem functions, and their economic and intrinsic values. In order to effectively classify the wide variety of vegetation communities found here, the framework developed by Robert Holland in 1986 has been added to and customized for San Diego County. To supplement the original Holland Code, additions were made by Thomas Oberbauer in 1996 to account for unique habitats found in San Diego and to account for artificial habitat features (i.e., 10,000 series).
