Cross Timbers and Prairies

The Cross Timbers and Prairies region is a transitional area for many plants and animals whose ranges extend northward into the Great Plains or eastward into the forests. Vegetation on the landscape of the Cross Timbers and Prairies Ecological Region of Northcentral Texas has undergone significant changes over the past 150 years. Early travelers through north Texas coined the name "Cross Timbers" by their repeated crossings of these timbered areas that proved to be a barrier to their travel on the open prairies to the east and west. The location of the East and West Cross Timbers was well known by these early travelers who used them as points of reference for travel.
