Description
Abstract
This existing vegetation map was produced for the eastern ranger districts (Austin/Tonopah, Ely, Jarbidge/Ruby Mountain and Santa Rosa) of the Humboldt-Toiyabe National Forest for use in the forest plan revision.  It provides baseline information about current vegetation composition, structure, canopy closure and broad landscape patterns.  Dominance Types, Sub-Cover Types, Cover Types, Canopy Closure, and Tree Size Class categories were generated from MRLC 2000 Landsat Thematic Mapper imagery, Digital Ortho Quads, and other ancillary data sets using advanced automated image classification and data mining techniques.  The project was completed in October 2004.

Purpose
This map provides the Humboldt-Toiyabe National Forest with a mid-scale (1:100,000) existing vegetation map to support the forest plan revision process and conduct needed regional assessments and analyses.  It also provides the forest with data for implementing Forest Service policies and regulations.  This map can be used to address a variety of important land management issues involving fuel loads, watersheds, rangelands, and wildlife habitat.  Feasible applications usually consist of describing vegetation diversity, assessing resource conditions, modeling species habitat, conducting benchmark analysis, designing monitoring procedures, or addressing a variety of other important land management issues.  Additionally, this map may provide a preliminary cut to determine where more detailed studies are needed.
