Summary

The purpose of this project is to classify and map vegetation communities in order to support natural resource management decisions, support the Department of Defense (DoD) mission, and ensure compliance with applicable Federal, state, and local statutes and regulations on Navel Base Ventura County San Nicolas Island.

Description

Vegetation classification and mapping was conducted at Naval Base Ventura County (NBVC) San Nicolas Island (SNI), California using the National Vegetation Classification Standard (NVCS). 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 community classification and resultant map based on a floristic vegetation classification to SNI.

The vegetation map classes represented the association level of the NVCS except in the case of Mediterranean California Naturalized Annual and Perennial Grassland, which was mapped to the group level due to the heterogeneity of the species composition in these stands. A total of 17 vegetation classes were identified on SNI. Of these, 16 vegetation classes were mapped aboard the installation using a 0.10 hectare (0.25 acre) minimum mapping unit (MMU) for a total of 5,600.51 hectares (14,225.26 acres) mapped. Surveys were conducted within select vegetation communities during four sampling periods between February and April 2013. A total of 157 classification plots representing 17 vegetative communities were sampled.

One community, Lycium californicum Association, was identified through classification sampling but was not able to be mapped because the sizes and photographic signatures of this communitys stands prevented identification through aerial photographs. Another community, Opuntia littoralis Alliance, did not meet the MMU but was able to be delineated due to its unique photographic signature in stands of significant sizes. These two communities were included in this report because of their importance as habitat for the federally threatened Island night lizard ( Xantusia riversiana ).
