Vegetation - Whiskeytown National Recreation Area Vegetation Mapping Project [ds986]

The vegetation map adheres to the 2008 National Vegetation Classification Standard (NVCS) and the Manual of California Vegetation (MCV) around 42,000 acres of the NRA land. The Association-Alliance map offers maximum classification detail with 38 classes (31 plant associations, 5 alliances, 1 Disturbed class and a Barren class), with the minimum mapping unit being 0.5 hectares.

Three source images were acquired by the Ikonos satellite on July 25, 2003 and used a spatial pattern recognition software package called Feature Analyst (Visual Learning Systems 2006) to identify groups of pixels associated with various vegetation categories. The previously developed, vegetation classification at Whiskeytown National Recreation Area served as the basis for making the vegetation map.
