The Red Hills physiographic region of
northern Florida was defined in 1914 as most of
Leon County north of the
Cody Scarp, and small portions of southernmost
Grady and
Thomas counties in Georgia. The original tree cover of the region was a
shortleaf pine-oak-hickory woodland with deep
sandy clay soil. A wider definition of the Red Hills Region includes
Jefferson County, Florida north of the Cody Scarp and the southern portions of Grady and Thomas counties in Georgia. This larger region consists of about that is bounded by the
Aucilla River on the east and northeast, by the
Ochlockonee River on the west and northwest, and by the Cody Scarp on the south. The Red Hills physiographic region is part of the Tallahassee Hills/Valdosta Limesink
ecoregion, which extends across northern Florida and southern Georgia from the
Apalachicola River to the vicinity of
Valdosta, Georgia. A wider Red Hills section of Florida has been defined as extending along the Alabama and Georgia borders, including, from east to west,
Madison, Jefferson, Leon,
Gadsden and
Jackson counties. There is a Red Hills Physiographic Province in south central Alabama. ==History==
