Vegetation maps of National Parks and National Monuments were developed to support natural resources management, planning, research and interpretation.
High resolution vegetation polygons mapped by the National Park Service. These data describe vegetation for the Whiskeytown National Recreation Area through the formation of polygons of similar vegetation cover. The desired minimum mapping unit was 0.5 hectares in size. However polygons as small as 0.1 hectares are included. Vegetation is classified according to the US National Vegetation Classification Standard (NVCS, http://www.fgdc.gov/standards/projects/FGDC-standards-projects/vegetation/NVCS_V2_FINAL_2008-02.pdf) to the association level when possible (31 classes), to the alliance level. A "Barren" class and a "Disturbed" class are also included for a total of 38 categories.
