Thorny brush species dominate the South Texas Brush Country. Mesquite, acacia, prickly pear, lotebush, granjeno, white-brush, Texas ebony and wild olive form dense, almost impenetrable thickets. The South Texas Brush Country is well known for producing trophy-class white-tailed deer. It is undoubtedly the most biologically diverse habitat in Texas, as tropical, grassland and desert species all inhabit this thorny shrubland in ecological harmony.
