The primary objective of this project was to create an accurate baseline vegetation map for the RPV-NCCP. When the NCCP was initially prepared in the late 1990s, floristic information of the area was based on existing surveys, many of which had been prepared for development projects. There was inconsistency in the terminology, level of detail, and scope between the various sources. The initial vegetation maps used in the draft RPV-NCCP were merged from several sources of data, which was adequate at the time. However, they did not provide the level of information that would be most valuable for long-term preserve management. This project has allowed for a detailed, on-the-ground vegetation survey of the PVNP using the California Native Plant Societys Vegetation Rapid Assessment protocol and the latest quantitative classification methods. The resulting vegetation classification follows the Manual of California Vegetation (Sawyer et al. 2009), which is the current standard for interpreting state-wide vegetation patterns and for initiating local and regional ecological assessments. The combination of survey data and the classification of the local vegetation were used to produce a detailed, accurate vegetation map of the PVNP.
The Palos Verdes Peninsula Land Conservancy (PVPLC) received grant funding through the California Department of Fish and Games Local Assistance Grant program to produce a fine-scale, spatially and floristically accurate vegetation map of the Palos Verdes Nature Preserve (PVNP). The PVNP is part of the draft Rancho Palos Verdes Natural Community Conservation Plan (RPV-NCCP) area, and encompasses approximately 1200 acres of protected open space. The PVNP is located in the City of Rancho Palos Verdes, in southern Los Angeles County. The project area represents several biologically rare habitat types, including coastal sage and cactus scrub. In addition, the PVNP hosts several rare and endangered plant and animal species, which are classified as covered species in the RPV-NCCP. Vegetation resources were assessed through field surveys, resulting in the classification analysis of 26 vegetation alliances, 38 vegetation associations or semi-natural stands, and mapping of 583 vegetation map polygons.
