This vegetation is based upon the 1992 Jones and Stokes vegetation survey for Orange County California. This dataset has since been superseded by more recent vegetation surveys, but is does form the basis for historic files with Orange County Parks GIS. The mapping and classification report for this dataset, Methods Used to Survey the Vegetation of Orange County Parks and Open Space Areas and The Irvine Company Property, is available here: http://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=99373. The habitat description and classification system report, Habitat Classification System Natural Resources Geograpahic Information System (GIS) Project, is available here: http://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=99370. An updated fine-scale regional vegetation map covering 86,000 acres located in both the Central and Coastal Subregions of Orange County was completed in 2012. The vegetation map is available for download here: ftp://ftp.dfg.ca.gov/BDB/GIS/BIOS/Public_Datasets/1300_1399/ds1336.zip.

Esri Sequential unique whole numbers that are automatically generated. SHAPE Feature geometry. Esri Coordinates defining the features. NVCSName The standardized name of the vegetation description used in the 2009 National Vegetation Classification System (see http://usnvc.org/). Since the NVCS does not have categories for human land use or otherwise unvegetated land, those descriptions were drawn from the California Wildlife Habitat Relationship. NVCSLevel The standardized level of the vegetation description used in the 2009 National Vegetation Classification System (see http://usnvc.org/). MapClass The finest level of vegetation type mapped (alliance, group, macrogroup, formation or division); or land use for polygons that are not natural vegetation, per the mapping classification. If a polygon was assigned a map class code but no corresponding description was provided in the classification, the polygon was assigned the next highest habitat type in classification hierarchy. MapClassCode Code for each vegetation type mapped. MapClassCodes are defined in the MapClass field. Referred to as VEGTYPE2 in the original dataset. VEGCLASS Vegetation classification John M. Taylor HABITAT_CL Habitat and land cover types assigned to each polygon. Stokes & Associates, Inc. 1993 (https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=99373) AQUATIC_CL Identifies if polygon is aquatic. SUBREGION Indicates the sub-region within the NCCP John M. Taylor CalVegName A crosswalk to the CalVeg vegetation system. Note that there may be a one-to-many relationship between CalVeg and NVCS. See http://www.fs.usda.gov/detail/r5/landmanagement/resourcemanagement/?cid=stelprdb5347192. CalVegCode A crosswalk to the CalVeg vegetation system. Note that there may be a one-to-many relationship between CalVeg and NVCS. See http://www.fs.usda.gov/detail/r5/landmanagement/resourcemanagement/?cid=stelprdb5347192. CWHRType A crosswalk to the California Wildlife Habitat Relationships system. Note that there is usually a one-to-many relationship between CWHR and NVCS. See http://www.dfg.ca.gov/biogeodata/cwhr/. CWHRCode A crosswalk to the California Wildlife Habitat Relationships system. Note that there is usually a one-to-many relationship between CWHR and NVCS. See http://www.dfg.ca.gov/biogeodata/cwhr/. GlobalRank The global rarity rank of the plant community (only for polygons mapped to the alliance level). G1: Fewer than 6 viable occurrences and/or 2000 acres worldwide; G2: 6-20 viable occurrences and/or 2000-10,000 acres worldwide; G3: 21-100 viable occurrences and/or 10,000-50,000 acres worldwide; G4: Greater than 100 viable occurrences and/or greater than 50,000 acres worldwide; G5: Community demonstrably secure due to secure worldwide abundance. See: http://www.natureserve.org/sites/default/files/publications/files/natureserveconservationstatusmethodology_jun12_0.pdf. StateRank The state rarity rank of the plant community (only for polygons mapped to the alliance level). S1: Fewer than 6 viable occurrences and/or 2000 acres statewide; S2: 6-20 viable occurrences and/or 2000-10,000 acres statewide; S3: 21-100 viable occurrences and/or 10,000-50,000 acres statewide; S4: Greater than 100 viable occurrences and/or greater than 50,000 acres statewide; S5: Community demonstrably secure due to secure statewide abundance. See: http://www.natureserve.org/sites/default/files/publications/files/natureserveconservationstatusmethodology_jun12_0.pdf. Rare Rarity of the vegetation type. Alliances and associations with state ranks of S1-S3 are considered rare. Yes Rare No Not Rare CaCode California Natural Community Codes - unique code assigned to alliances and associations. UID Unique identifier for each polygon. The last five digits correspond to the ALLVEG_ID field in the original dataset. NVCSAlliance The standardized name for the alliance within the 2009 National Vegetation Classification System. See http://usnvc.org/. NVCSGroup The standardized name for the group within the 2009 National Vegetation Classification System. See http://usnvc.org/. NVCSMG The standardized name for the macrogroup within the 2009 National Vegetation Classification System. See http://usnvc.org/. ACRES GIS-calculated area measurements of each mapped polygon. HECTARES GIS-calculated area measurements of each mapped polygon. SHAPE_Length Length of feature in internal units. Esri Positive real numbers that are automatically generated. SHAPE_Area Area of feature in internal units squared. Esri Positive real numbers that are automatically generated. Note: certain fields have been added by the Department of Fish and Wildlife's Vegetation Classification and Mapping Program. These include crosswalks to the Wildlife Habitat Relationships and CalVeg classification systems, Global and State Ranks, CaCode and the fields relating the mapping units to the National Vegetation Classification System as it is described for California in the 2nd edition of the Manual of California Vegetation 20180302 Nature Reserve of Orange County John M.
