Description:
Abstract:
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 ECOMAP (1993) as
units the "landscape scale" as follows: "groupings of
Landtypes or subdivisions of Subsections based upon
similarities in geomorphic process, geological rock types,
soil stream types, lakes, wetlands, and series,
subseries, or plant association vegetation communities.
Repeatable of soil complexes and plant communities are
useful delineating map units at this level. Names of
Landtype
Associations are often derived from geomorphic history and
vegetation community." Mountainous terrain was delineated
only at the higher subsection level as finer sub-divisions
are the purview of the U.S. Forest Service
Purpose:
This dataset is the result of a contract between the Bureau
of Land Management (BLM) and the University of Wyoming
Dept. of Botany to delineate a hierarchical set of
landunits for Southwest Wyoming. These results will also
contribute to a multi-agency effort to develop a common
ecological map of the United States. The purpose of these
units is ultimately to provide a framework for organizing
data for resource management by ecological units instead of
political units

analysis layer
Process_Step:
Process_Description:
These analysis layers were used interactively to compare
the information in each. In general, once distinct units
were at any hierarchical level, they were delineated
with data for whichever variable was the principal
controlling at a given arc along a polygon. This is
essentially
the "method of controlling variables" described by Bailey
(1996) in which the appropriate controlling variable is
selected to set the boundary of a particular land unit.
