| | History of Southern Pine Ecosystems (Site not responding. Last check: 2007-10-29) |
 | | Roughly one quarter of the longleaf communities also supported other pines such as loblolly, shortleaf, slash, and pond pine in various proportions depending on soil conditions, especially in transitional zones between the coastal plains and other physiographic regions. |
 | | Shortleaf pine was prevalent outside the range of longleaf, especially on dry slopes and ridges in the Interior Highlands and Oklahoma, and has declined considerably. |
 | | Original pine forests were old, open, contained a two-layered structure of canopy and diverse grass and forb groundcover, and were dominated by longleaf in the coastal plain, longleaf/shortleaf/loblolly in the Piedmont and interior highlands, and slash pine in south Florida. |
