Preliminary Classification of Terrestrial Ecosystems in Southeast AlaskaConservation Assessment for Southeastern Alaska and the Tongass National Forest
The Preliminary Classification of Terrestrial Ecosystems in Southeast Alaska is based on 4 major data layers: USDA Forest Service Existing Vegetation database, the National Wetland Inventory, the USDA Forest Service Landforms and Karst from USFS soils and karst inventories. These layers were merged with auxillary sources from Landsat Enahnced Thematic Mapper (ETM) and supplemented with aspect and elevation from the Shuttle Radar Topography Mission Digital Elevation Model (SRTM DEM) . This master database retains all of the detailed features from each of these datasets to allow maximum flexibility for future researchers to use unique combinations of habitat variables that suit their subject of interest.
