Michigan Natural Features Inventory 19950101 vector digital data St. Paul. MN USDA Forest Service North Central Forest Experiment Station 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. 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. 20140310 Publication date Complete Irregular -90.052353 -82.072975 48.197796 41.633936 This database is not to be released to anyone at this time 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.
