Nope,the "Cross Timbers" is one of the ecological regions of Texas.I know that the term is also used to describe a much larger area extending into other states,but I use it as a clearly defined geographic area in Texas.To this day ,the Post Oak pastures have little blue stem[a tall grass] and the mesquite pastures have buffalo grass or mesquite grass.
The stirrup high grass was in the Rolling Plains,just West of the Cross Timbers , and up on the Caprock.
We are in the post oak belt. Sandwiched between the Pine belt, generally east of the Trinity, and the Blackland, generally west of the Brazos. Crosstimbers is futher north west.
So I was told the upland pariries were both little and big bluestem and a lot of "Indian Grass" which I think is switch grass. Same grass the Caddo, and others, used to build their houses.
The Keechi (Kitsi, Quchi, etc) moved into this area after our local bunch, Deadose, all more or less died out from induced desease in the late 1700's.
