HDR, Inc, GIS 20121130 Vegetation - Point Mugu [ds1500] vector digital data http://bios.dfg.ca.gov/ ftp://ftp.wildlife.ca.gov/BDB/GIS/BIOS/Public_Datasets//1500_1599/ds1500.zip Vegetation classification and mapping was conducted at Naval Base Ventura County (NBVC) PointMugu, California using the National Vegetation Classification Standard (NVCS) and the CaliforniaDepartment of Fish and Wildlife Vegetation Classification and Mapping Program. Objectives were to:(1) survey, map and classify vegetation communities in order to produce a product that is consistent,repeatable, and translatable to regional/national levels; and (2) provide a vegetation communityclassification and resultant map based on a floristic vegetation classification to Point Mugu.The vegetation map classes represent the association-level of the NVCS. A total of 68 vegetationassociations were mapped on the installation using a 1/16 acre Minimum Mapping Unit (MMU) for atotal of 4307.3 acres mapped. Surveys were conducted within select vegetation communities during foursampling periods between January and July 2012. No surveys were conducted during several months inthe spring to avoid potential impacts to breed federal and state-listed bird species. A total of 110 plotswere surveyed which included 42 vegetation associations. Approximately 30 vegetation associationssupport or have the potential to support species of special interest, including federal and state-listedthreatened and endangered species. Additionally, some of the same vegetation communities that supportthese species are components of tidal wetlands, a sensitive and biodiverse ecosystem.Other than developed/landscaped/unvegetated areas (30.3 percent) mapped on Point Mugu, Salicorniapacifica – Frankenia salina Association was the most common association with 12.6 percent of the landarea. The next most common mapped association was open water with 8.6 percent. Approximately33.8 percent of Point Mugu is dominated by native vegetation while 17.5 percent is dominated by nonnative vegetation. In addition, approximately 6.8 percent was mapped as tidal/sand/mudflats. The purpose of this project is to classify and map vegetation communities in order to support informed land management decisions on NBVC Point Mugu, support the Department of Defense mission, and ensure compliance with applicable Federal, state, and local statutes and regulations.
