South Texas Plains Ecoregion
Wildlife Management Plan for Live Oak County, Texas
Live Oak County sits at the convergence of 3 Texas ecoregions, with 71 documented wildlife species.
Intelligence Snapshot
Regulatory Complexity
Live Oak County has elevated conservation considerations that affect wildlife management planning. The 4 federally listed species documented here mean that brush management, water development, and habitat modification must be designed with ESA compliance in mind. The county spans 3 ecoregions. A plan written for the wrong landscape position could prescribe inappropriate intensity standards or target the wrong species assemblage. A properly calibrated plan accounts for these constraints. A generic plan does not.
Live Oak County Ecological Profile
Live Oak County's 1,040 square miles contain 12,381 documented oil and gas wells alongside thornscrub brushlands and caliche ridges, creating a landscape where industrial infrastructure and ecological management coexist at close range. 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. Lake Corpus Christi State Park provides a nucleus of protected habitat and a reference landscape for private land management in the surrounding area.
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.
Transitional Ecoregion
Live Oak County intersects 3 distinct ecoregions: East Central Texas Plains, Southern Texas Plains, and Western Gulf Coastal Plain. This is not a minor detail. A plan calibrated to the East Central Texas Plains would prescribe the wrong intensity standards, the wrong target species, and the wrong management timeline for a property in the Western Gulf Coastal Plain zone. Property-specific ecoregion classification is the first step in any credible plan.
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.
Spans 3 ecoregions: East Central Texas Plains, Southern Texas Plains, Western Gulf Coastal Plain
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.
Live Oak County Species of Conservation Concern
TPWD records 71 species in Live Oak County. Birds represent the most documented group at 28 species. The 4 federally listed and 14 state-protected species documented here represent meaningful regulatory considerations for any land management activity. Federally listed species include whooping crane and ocelot. Whooping crane: Winters along the Texas coast at Aransas NWR and surrounding marshes.
Primary Management Targets
white-tailed deer, bobwhite quail, javelina, wild turkey
Listed Species
Winters along the Texas coast at Aransas NWR and surrounding marshes. Grain field management and wetland water levels in coastal counties affect foraging habitat. Disturbance within 1,000 feet of roosting sites is regulated.
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.
Nests on bare sand and shell flats along the Gulf Coast. Coastal properties must avoid disturbance to nesting areas during breeding season (March through August). Vehicle traffic on beaches in occupied habitat is restricted.
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.
Nests on bare sand and gravel bars along rivers and reservoirs. Disturbance during nesting season (May through August) must be avoided. Water level management at reservoirs affects nesting success.

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.
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 Live Oak 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. Because the county spans 3 ecoregions, the applicable intensity standards depend on where the property sits. For the South Texas Plains portion, TPWD requires 20 to 30 minimum acres, 15% brush management, and annual census documentation (34 TAC Section 9.2002). 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 Live Oak 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.
