The Stake Plains of Texas are included in this province. Texas landscape northwest of Amarillo. Mesquite is the principal shrub shown.
Summers are long and hot, and winters are short and mild.
The frost-free season ranges from about 130 to considerably more than 300 days. From May to October, potential evaporation is about twice the precipitation. On the Edwards Plateau, oak and juniper are often mixed with grasses and mesquite, and on steep rocky slopes these trees may form closed stands. The most characteristic tree is Ashe juniper. On slopes leading down to the Rio Grande, the ceniza shrub dominates.
