vector digital data https://www.wildlife.ca.gov/Data/BIOS https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/2800_2899/ds2856.zip The California Native Plant Society (CNPS) Vegetation Program has produced a fine-scale vegetation map for the Point Arena-Stornetta Unit of the California Coastal National Monument. The vegetation map encompasses 1,668 acres and was produced using heads-up digitizing based upon 2016 National Agricultural Imagery Program (NAIP) aerial imagery from Mendocino County. The minimum mapping unit (MMU) was 1 acre, with exceptions for wetland and other special types (0.25-acre MMU). The classification and map follow the National Vegetation Classification Standard and State of California Vegetation and Mapping Standards. The map includes 45 map units, of which 35 are natural vegetation types, six are exotic vegetation types and four are non-vegetated types (e.g., coast range cliffs, developed, agriculture, dune/sand). While the primary map attribute is vegetation type, additional map attributes include structural information (e.g., herbaceous, shrub and tree cover), disturbance and site quality information. The fine-scale vegetation map and supporting field survey data provide baseline information for long-term land management, conservation, and wildlife protection within the only accessible terrestrial component of the California Coastal National Monument. The vegetation map and crosswalk were prepared for BIOS publication by CDFW staff. Full report is available from: http://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=174856 The vegetation mapping project for the Point Arena-Stornetta Unit was completed by the California Native Plant Society (CNPS) for the US Bureau of Land Management (BLM). The project was implemented in four primary stages: 1) collection of field data to inform vegetation classification; 2) preparation of a key to the vegetation types based on survey data; 3) creation of a Unit-wide, fine-scale vegetation map based on the vegetation key; and 4) post-mapping ground truth data used to verify map accuracy. The data presented in this vegetation map will allow for informed management activities, the identification and maintenance of habitat suitable for federally listed plant and animal species, and an increased understanding of ecosystem functions and processes within the Unit. -123.738632 -123.694479 38.958629 38.911148 None vegetation point arena stornetta None This dataset was created by California Native Plant Society.

Ranks are based on a set of criteria including the rarity of the community (extent and occupancy), the threats that the community is subject to, and any known trends in the quality, size, or quantity of stands within the state. Ranks go from G1 which is critically imperiled/has very few occurrences to G5, when a community is demonstrably secure due to broad distribution with area not subject to threats. Ranks G1-G3 are considered sensitive.

Ranks go from S1 which is critically imperiled/has very few occurrences to S5, when a community is demonstrably secure due to security globally. Ranks S1-S3 are considered sensitive.
