The Terrestrial class includes upland ecosystems that have xeric to mesic soils with plants adapted to these growing conditions. The Terrestrial class includes 18 upland natural community types, which are organized into the three ecological groups of Prairie, Savanna, and Forest based on community structure. Further classification to natural community type is based on species composition, soil characteristics, natural processes, geographic distribution, and landscape setting.
