The Cross Timbers is an ecoregion in the central United States, characterized by a mix of forest, woodland, and prairie ecosystems. It spans parts of Texas, Oklahoma, and Kansas, covering approximately 47,000 square miles (120,000 km²). The region is known for its unique combination of oak forests and grasslands, which support a diverse range of flora and fauna.

Geography

The Cross Timbers region is situated between the Great Plains to the west and the Eastern deciduous forest to the east. It is bordered by the Central forest-grasslands transition to the north, the Central Great Plains to the northwest, the Flint Hills to the northeast, the Ozark Highlands to the east, and the Western Gulf coastal grasslands to the south.

Efforts to conserve the region's biodiversity include the establishment of protected areas and the implementation of sustainable land management practices.

Human History

The Cross Timbers has a rich cultural history, with evidence of Native American habitation dating back thousands of years.
