Ecological SubsectionsEcological Subsections of Southeast Alaska and Neighboring Regions of Canada

This geospatially explicit vector-based polygon dataset identifies 85 terrestrial ecological subsection delineations present in Southeast Alaska and the Tongass National Forest. Within each subsection one can expect to find a relatively consistent occurence and distribution of vegetation types. Due to the hydrologically-influenced geomorphology of Southeast Alaska specific key indicators of physiography, lithology, and surface geology were employed to systematically distinguish terrestrial ecosystems.
