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.", "summary": "", "title": "Ecoregions", "tags": [], "type": "", "typeKeywords": [], "thumbnail": "", "url": "", "minScale": 0, "maxScale": 0, "spatialReference": "", "accessInformation": "", "licenseInfo": "" }
