The objective of this study was to produce a baseline GIS vegetation map for use by the Nature Conservancy and others in monitoring and managing the reserve. Data were derived principally from remote sensing imagery, using the ADAR imaging system, with some support from ancillary field data. Additional objectives were to define appropriate standardized methods for mapping the site to meet reserve management needs and to develop a database structure that facilitates use in monitoring and management applications. Some of these applications include monitoring changes in habitat type, size, and shape; species compositions; densities and distributions of exotic plants species; and fire recovery.
The use of Airborne Data Acquisistion and Registration (ADAR) imaging system was used to create a map displaying existing plant communities within the Nature Reserve of Orange County's coastal subregion. The vegetation classification was based on Jones and Stokes, 1993, with some modifications based on vegetation characteristics in the subregion. For a complete list of habitat codes with decision rules, see Appendix B of the associated report ADAR-Based Mapping of the Nature Reserve of Orange County, for The Nature Conservancy and California Department of Fish and Game, prepared by Ed Almanza and Associates, https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=17016 .

What Each Record Represents: Each polygon represents a discrete plant community.
