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.
Quercus stellata, the post oak or iron oak, is a North American species of oak in the white oak section. It is a slow-growing oak that lives in dry areas on the edges of fields, tops of ridges, and also grows in poor soils, and is resistant to rot, fire, and drought. Interbreeding occurs among white oaks, thus many hybrid species combinations ...

The sanctuary preserve significant portions of Post Oak Savannah ecosystem, featuring live oak trees and native wildflowers. The area includes a Riparian Forest along Barton Creek, that provides habitat for bird species such as herons and hawks.
In addition, the park is part of the Post Oak Savannah, an ecological region of 8,500,000 acres (3,400,000 ha) of hilly lands that includes scattered oaks, mainly post oaks and blackjack oak. Most of this ecoregion is somewhat arid due to its clay soil, but the area in Bastrop is an exception.

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]
Fayette County Reservoir is located within the Post Oak Savannah ecoregion in Texas. Habitat in the littoral zone is mainly natural and rocky shoreline. The water level is supplied and maintained by the Colorado River. [3] Its function as a power plant cooling reservoir increases water temperatures throughout the lake.
