Summary

The purpose of the current vegetation mapping effort was to refine the earlier map created for the Multiple Species Conservation Program planning areas (1=2000 scale map generated by 1990 aerial photo interpretation), update vegetation changes due to fire or other disturbances, and provide a baseline for long-term monitoring comparisons. Monitoring through the use of vegetation mapping also will assist the Reserve's managers in maintaining ecosystems and vegetation communities that support sensitive species and fragile, irreplaceable resources.

Description

This layer represents vegetation communities in the Department of Fish and Game's Crestridge Ecological Reserve. The County of San Diego, the Conservation Biology Institute (CBI) and Fred Sproul, an independent biologist, created this vegetation layer in the spring of 2000 using high resolution digital multispectral imagery captured by the Airborne Data Acquisition and Registration (ADAR) system and field reconnaissance (scale: approximately 1"= 328'). Vegetation was mapped according to the modified Holland system of classification (Oberbauer 1996); using this system ensures compatibility with San Diego Association of Government's (SANDAG's) regional vegetation database. The dominant vegetation type found at the almost 2,400 acre Reserve was Southern Mixed Chaparral with approximately 1,758 acres present. Coastal Sage Scrub was the next dominant vegetation type with approximately 444 acres present.

Supplemental information
Vegetation mapping was conducted primarily by direct observations and from vantage points using binoculars. A few areas in the eastern portion of the site were inaccessible and were mapped from the imagery alone. The County of San Diego GIS staff digitized the vegetation boundaries, calculated acreages, and produced a map of vegetation communities. For descriptions of these vegetation communities use the link to the Conservation Biology Institute and go to Appendix A.1. A list of plant species was developed, and dominant species composition was recorded for nearly half of the vegetation polygons. This study was funded by the California Department of Fish and Game's Local Assistance Grant Program, Contract# P9950022. Digital data were collected and compiled after the completion of the project to develop a spatial layer and associated metadata to create a BIOS submittal. This was done as part of the Southern California Data Integration Project. Animal observations were gathered as part of the project but digital data were lost.
