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.
This dataset is a scientifically based, hierarchical system of map units for Southwestern Wyoming that incorporates ecological principles and processes across a range of scales. These units are a mapping of terrain features having similar terrain configuration, ecological properties and management implications within which situational landscape-ecosystems can logically and conveniently be defined. While the process of delineation of these units is subjective, units are hierarchically nested into the structure of the ECOMAP (1993) national hierarchy of ecological units. The includes Landtype Associations as well as higher hierarchical units in which Landtype Associations are imbedded. Associations are defined by...
