University of MichiganThe Physiographic Systems of the Nichols Arboretum were defined by Alan Tepley in his 2001 Master's Thesis at the University of Michigan. Physiographic Systems are complexes of landforms typically of one recognizable, generic kind (e.g. moraine, outwash plain, ice-contact terrain, or lake plain). The boundaries were defined by using field reconnaissance, the establishment of sample plots and soil pits, laboratory work and data analysis. Overall, a total of 3 Physiographic Systems, 9 Landform Level Ecosystems, and 19 Landscape Ecosystem Types were identified, described, and mapped.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/026c06de0e7b49188a3e277dc8b35010_1engUM Matthaei Botanical Gardens and Nichols ArboretumPublicPhysiographic Systems of the Nichols Arboretum [Michigan]Web servicesMichiganLast Modified: 2019-04-29
