Cross Timbers

description Cross Timbers Overview

The Cross Timbers is a broad ecological region extending through parts of Texas and Oklahoma and reaching into southern Kansas. It consists of alternating woodland, savanna, and prairie, with post oak and blackjack oak as characteristic trees and native grasses occupying more open areas. The region forms a transition between the Great Plains to the west and eastern deciduous forest to the east, and its sandy or sandy-loam soils help shape the vegetation. It is studied in ecology, conservation, geography, and the environmental history of the southern Great Plains.
