The document lists 16 tree species and provides information about plant communities and environmental factors that determine plant distributions. Specifically, it discusses gradients of available soil moisture from lowland wet to upland dry habitats and the influence of shade tolerance. It also defines terms like mesic, xeric, and the wetland indicator status codes OBL, FACW, FAC, FACU, and UPL.
