Joshua Tree National Park Aerial Information Systems 2 vector digital data https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/700_799/ds730.zip https://www.wildlife.ca.gov/Data/BIOS A vegetation layer created by Aerial Information Systems (AIS) for Joshua Tree National Park (JOTR) in the late 1990's. Since the initial work, an accuracy assessment (AA) was conducted during 2007 and 2008, in addition to a rapid assessment (RA) during 2009. Data collected through the AA and RA not only gauged the accuracy of the AIS's aerial photo interpretation but also the initial in-field vegetation key written by JOTR. The AA and RA data was further used in validating changes to both the vegetation layer's attribute information and polygon geometry. This feature class serves as the final version of the vegetation layer after changes based off of the AA and RA. USE THIS VEGETATION LAYER TO REPRESENT JOTR.

Note: certain fields have been added by the Department of Fish and Game'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. Macrogroups may differ from the original vegetation classification. The original classification follows the nested hierarchy of the NVC (Federal Geographic Data Committee 2008) while this map follows the NVC as adapted for California from "A Manual of California Vegetation, 2nd Edition" (Sawyer et. al. 2009), Appendix 3, pp. 1227-1240.
