South Texas Plains Ecoregion
Wildlife Management Plan for Maverick County, Texas
Maverick County lies within the South Texas Plains ecoregion of Texas, with 61 documented wildlife species.
Intelligence Snapshot
Regulatory Complexity
Maverick County has elevated conservation considerations that affect wildlife management planning. The 3 federally listed species documented here mean that brush management, water development, and habitat modification must be designed with ESA compliance in mind. A properly calibrated plan accounts for these constraints. A generic plan does not.
Maverick County Ecological Profile
Maverick County's 1,280 square miles of thornscrub brushlands and caliche ridges carry an environmental legacy: 44 orphan wells on the Railroad Commission's plugging priority list alongside active ecological management. 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. With 4 Groundwater Conservation Districts regulating water resources, well permitting and production limits are significant factors in water-dependent management practices.
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.
Soil Conditions
Soils range from deep, loamy Duval and Miguel series on the Coastal Sand Sheet to shallow, calcareous Webb and Maverick clays on caliche-capped uplands, with saline Montell clays along the Rio Grande floodplain.
Fire Ecology
Fire plays a secondary role to mechanical brush management in the South Texas Plains, where thornscrub species resprout aggressively from the root crown. Prescribed fire is most effective on sandy soils where it can top-kill herbaceous weeds and young brush regrowth following mechanical treatment.
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.
Maverick County Species of Conservation Concern
TPWD records 61 species in Maverick County. Birds represent the most documented group at 23 species. The 3 federally listed and 17 state-protected species documented here represent meaningful regulatory considerations for any land management activity. Federally listed species include ocelot and Texas hornshell. Ocelot: Requires dense thornscrub corridors for movement between habitat patches in the lower Rio Grande Valley and coastal counties.
Primary Management Targets
white-tailed deer, bobwhite quail, javelina, wild turkey
Listed Species
Requires dense thornscrub corridors for movement between habitat patches in the lower Rio Grande Valley and coastal counties. Brush retention along wildlife corridors is a conservation priority. Road crossings are a primary mortality source; wildlife underpasses may be required for road projects.
Freshwater mussel found in the Rio Grande and Pecos River. Water diversion, reduced flows, and poor water quality are primary threats. Flow maintenance is critical.
Western distinct population segment is threatened. Requires large patches of mature riparian woodland (cottonwood, willow) with dense understory. Clearing riparian corridors wider than 300 feet may trigger consultation in designated critical habitat.
Requires dense thornscrub corridors for movement between habitat patches in the lower Rio Grande Valley and coastal counties. Brush retention along wildlife corridors is a conservation priority. Road crossings are a primary mortality source; wildlife underpasses may be required for road projects.
Freshwater mussel found in the Rio Grande and Pecos River. Water diversion, reduced flows, and poor water quality are primary threats. Flow maintenance is critical.
Depends on harvester ant colonies for food. Fire ant suppression and native grassland restoration directly benefit this species. Listed as state threatened.
Found in South Texas brushlands and western Edwards Plateau. Slow-moving and vulnerable to road mortality and habitat clearing. Translocation may be required before land clearing in occupied habitat.

South Texas Plains Wildlife Management Standards
In Maverick County, brush management is surgical. The objective is sculpting brush patterns to maximize edge habitat for deer and quail, not clearing brush to bare ground. Under 34 TAC Section 9.2002, the South Texas Plains ecoregion requires 20 to 30 minimum acres, 15% brush management coverage, and annual wildlife census documentation. Primary targets are white-tailed deer, bobwhite quail, and javelina. Practice recommendations should reflect each property's specific landscape position within the county.
These are the intensity thresholds your plan must meet for the South Texas Plains ecoregion. Your county appraisal district will verify compliance against these minimums. A plan that does not address them risks denial of your wildlife management valuation. For a complete overview of the seven management pillars, see the management pillars guide.
In Maverick County, brush management targets mesquite canopy reduction while retaining enough woody cover for wildlife escape habitat.
Food plots must provide nutritional supplementation for target species. The minimum size and density are set by ecoregion to reflect carrying capacity.
Feeder placement and protein content are auditable. The aflatoxin threshold (20 ppb) is a compliance requirement, not a suggestion.
Fire ant suppression directly supports native harvester ant populations, the primary food source for Texas horned lizard and other ground-foraging species.
Brown-headed cowbirds are brood parasites that reduce nesting success of songbirds. The minimum applies to properties where cowbird trapping is selected as a management activity.
The burn rotation percentage applies over the full plan period. Properties that cannot burn due to WUI constraints must document the limitation and substitute equivalent mechanical treatment.
Nest box density is based on territory size of target cavity-nesting species. Boxes must be monitored and maintained annually.

Water Resources
4 Groundwater Conservation Districts regulate water resources in the county, with permitting requirements for new wells and production limits that affect agricultural and wildlife management water sources.
Infrastructure
The Railroad Commission documents 4,744 wells and 725 pipeline segments in Maverick County, a moderate industrial presence alongside agricultural land use. 44 orphan wells are on the Railroad Commission's plugging priority list.
61 species in 1280 square miles of thornscrub. In Maverick County, the brush is the habitat. The plan shapes it rather than clearing it.
