Land type Associations

This dataset is a scientifically based, hierarchical system of map units (image) for Wyoming that incorporates ecological principles and processes across a range of scales. Land type associations 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, the units are hierarchically nested into the structure of the ECOMAP (1993) national hierarchy of ecological units (image). Different mapping methods (image): Land type associations delineated in 1996 and 1997 for the southeast and southwest portions of Wyoming were based on a subjective process. The subsequent mapping of northwest Wyoming and the Buffalo Resource area (north-central) was based on a different delineation process, using a terrain characterization process based on empirical analysis modified from Hammond (1964). Details of methods used are provided in the following report: W.A. Reiners, Axtmann E.V., and R.C. Thurston. 1999.
