Basic Hardpan Oak-Hickory Forest

This is the most floristically diverse vegetation type of all Piedmont, Fall Zone, and Coastal Plain types. This community is distinguished from other oak-hickory forests by its patch-dominance of forest grasses and its strong association with sub-level topography and soils with an impermeable hardpan or shallow bedrock. It is found west of Washington DC in the Triassic Basin region.
