Description:
The EPA EnviroAtlas Percent Forest and Woody Wetland per 12-digit HUC dataset was clipped to California sub-watersheds (NRCS).  

Original Metadata:

This EnviroAtlas national map estimates the percentage of total land within each subwatershed (12-digit HUC) that is covered by trees and forest or woody wetlands. The map layer uses the 2006 National Land Cover Database (NLCD) to define forested land and woody wetlands and it excludes agriculture, developed, and barren land.

These data were generated by using the 2006 National Land Cover Dataset (NLCD) in the landscape assessment tool, Analytical Tools Interface for Landscape Assessments (ATtILA). ATtILA is an Esri ArcView extension (soon to be updated to an ArcMap toolbox), created by EPA, that calculates many commonly-used landscape metrics. NLCD classes 41 Deciduous, 42 Evergreen, 43 Mixed Forest, and 90 Woody Wetlands were used for this map. The landcover data were summarized by 12-digit HUC boundaries taken from the Watershed Boundary Dataset (WBD). For more information on the metric calculation, see the ATtILA User’s Manual.
