Pine savanna (pine land) extended to the Atlantic plain (1779 map). The oak-hickory forest of the Northeast was primarily burned by Native Americans, resulting in oak openings, barrens, and prairies in the Northeast and the Piedmont of North Carolina. There was nearly annual burning throughout the Northeast. [7]
The longleaf pine ecosystem is a temperate coniferous forest ecosystem found within the Southern United States. Spanning pine savannas, sandhills and montane forests, it includes many rare plant and animal species, and is one of the most biodiverse in North America. [1]
A second key factor is moisture. Overall, wet pine savannas have more species than pine savannas, and the distribution of each species within a savanna is intimately connected with soil moisture regimes. Temporary ponds, and seepage areas, are therefore a critical control on plant species composition.
In the far southwest was California oak woodland and Ponderosa Pine savanna, while further north was the Oregon White Oak savanna. The Central Hardwood Region covers a wide belt from northern Minnesota and Wisconsin, down through Iowa, Illinois, northern and central Missouri, eastern Kansas, and central Oklahoma to north-central Texas, with ...
These are woodlands dominated by longleaf pine (Pinus palustris) and subject to frequent fires.The Atlantic coastal plain upland longleaf pine woodlands occur on uplands and on the higher parts of upland-wetland mosaics, while the east Gulf coastal plain interior upland longleaf pine woodlands occur on rolling dissected uplands, inland of the coastal flatlands.
Map of oak savanna distribution in North America. Although there are pockets of oak savanna almost anywhere in North America where oaks are present, there are three major oak savanna areas: 1) California, British Columbia, Washington and Oregon in the west; 2) Southwestern United States and northern Mexico; and 3) the prairie/forest border zone of the Midwestern United States.
The wet pine savannas support rare and endangered plant and animal species, such as the orchid Calopogon multiflorus, gopher frogs, and gopher tortoises.These habitats also have numerous carnivorous plants, particularly pitcher plants; [5] Buttercup Flats has an international reputation in this regard. [6]
The pine wetland savannas had scattered longleaf pine along with shrubs of sweetbay, wax myrtle, titi, and holly, and a diverse herbaceous layer of grasses, sedges, and, in some places, insectivorous plants and orchids. These wetland savannas are one of the rarest habitat types in Texas with only a few small fragments receiving any protected ...
