Title: Ecoreg100 - Regional landscape ecosystems of Michigan
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
This Ecoregion database was delineated by Dennis Albert for Michigan. Hierarchial units include Section, Subsection, and Sub_subsection. Ecosystem components used to distinguish major landscapes are macroclimate, physiography, soil and vegetation. In Michigan, long-term climatic records were a primary component in delineating the larger hierarchical units - sections and subsections. Physiography was used in conjustion with climatic data to refine section and subsection boundaries. At the sub-subsection level, the primary determinants of boundaries were physiography and soil conditions.
Purpose:
Ecoregional boundaries were designed for wide usage in scientific studies, resource inventories on an ecological basis, and a wide range of management activities. This includes strategic planning on a multi-forest, statewide and multi-agency basis.

Access_Constraints: This database is not to be released to anyone at this time.
Use_Constraints:
USE WITH CAUTION....at this time the linework is in question due to projection parameter questions and the unknown original sources of the databases used to create these lines. The 1:500,000-scale geology database was used as one of the sources, so the largest spatial error can be similar to 500K databases.
