Wildlife Management Plan
Hidalgo County

The South Texas Plains, often called the Brush Country, is a semi-arid landscape of thornscrub, caliche ridges, and sandy loam flats extending from the Balcones Escarpment south to the Rio Grande. Honey mesquite, brasil, granjeno, and blackbrush acacia form dense, thorny thickets that harbor some of the largest white-tailed deer in the world. This is the region that produces the trophy bucks that drive a multi-billion dollar hunting economy, and wildlife management here has been refined over generations of South Texas ranching families.

Brush management in the South Texas Plains is surgical. Unlike regions where the goal is broad-scale brush removal, management here focuses on sculpting brush patterns to create the interspersion of dense cover and open senderos that maximize edge habitat for deer and quail. Root-plowing and roller-chopping in alternating strips, combined with prescribed fire on a 3 to 5 year rotation, creates the mosaic of successional stages that wildlife requires. Supplemental feeding is widespread, and protein feeders placed at strategic locations help maintain deer body condition and antler development through the nutritionally stressful late-summer months. Water management is critical in this semi-arid region, with windmill-fed stock tanks, solar-powered wildlife waterers, and rainwater catchments distributed across the landscape to ensure no animal is more than half a mile from water.

White-tailed deer management drives the economy of the South Texas Plains, with mature bucks regularly scoring above 150 inches on the Boone and Crockett scale. Northern bobwhite and scaled quail populations fluctuate dramatically with rainfall, and intensive habitat management can buffer these swings. Javelina, nilgai antelope (an exotic from India now established in several South Texas counties), and feral hog are common ungulates requiring active population management. Rio Grande wild turkey thrives in the brushlands along creek corridors. Ocelot and jaguarundi, two federally endangered cats, survive in the dense thornscrub of the lower Rio Grande Valley, making brush retention along wildlife corridors a conservation priority.
