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.
Overgrowth shades and stunts longleaf pine seedlings, undergrowth increases, and succession creates the southern mixed hardwood forest where savanna used to be. Intentional use of fire to manage vegetation began to be accepted again after World War II, and at present about 6,000,000 acres (24,000 km 2 ) a year are burned.
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 ...
The Miskito pine forests ecoregion (WWF ID: NT0306) covers lowland pine forests and savanna along much of the Mosquito Coast in northeastern Nicaragua and southeastern Honduras. Pines are adapted to grow in the poor soil, relative to the surrounding moist forest, and repeated burning have left one species – the Caribbean pine – dominant ...
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.
Savannas Preserve State Park is predominantly a savanna; open grasslands with sparse South Florida slash pine trees. The park is made up of pine flatwoods, basin marsh, scrubby flatwoods, wet prairie and the Atlantic scrub ridge. Protecting southeast Florida's largest freshwater marsh, the Savannas Preserve State Park manages over 7,000 acres.
