The South Texas Plains on the ground

The South Texas Plains — the Brush Country — is a dense thornscrub of mesquite, blackbrush, and granjeno south of San Antonio, home to the most famous white-tailed deer genetics in America and the ranching culture that manages them. Wildlife management is a way of life here, and appraisal districts see some of the most sophisticated plans in the state.

South Texas grows the biggest whitetails in the state on native thornscrub browse; strip-pattern brush management that keeps 40–60% canopy is the signature habitat practice of the region. Typical target species for plans in this region include trophy white-tailed deer, bobwhite quail, Rio Grande turkey, javelina, chachalacas in the Valley, and ocelots in remnant thornscrub.

What limits wildlife here

A wildlife management plan is most convincing when it takes on the problems that actually constrain wildlife in its region rather than listing generic good deeds. In the South Texas Plains, those are buffelgrass monocultures displacing native forage, drought cycles, and clearing that removes too much thermal cover — and each one is a practice waiting to be written down. A plan that names a real local problem, commits to work at regional intensity, and documents it is the plan that gets approved and stays approved.

Start with three

You need at least three of the seven qualifying practices each year under Texas Tax Code §23.51(7). For most South Texas Plains landowners the natural opening three are habitat control, supplemental water and census counts: habitat control is where the real management happens, water is the quickest to install and the easiest to photograph, and a census generates dated evidence every single year. You can change which three you run as the land changes — the statute asks for three practices performed and documented, not three particular practices forever.

The seven practices, South Texas Plains-style

Every Texas plan draws from the same seven practices. What changes by region is what each one looks like — and a plan that describes the wrong version for its ecoregion is the fastest way to draw questions from a chief appraiser. Here is what each practice means in the South Texas Plains:

1

Habitat control

Strip or mosaic brush sculpting that retains 40–60% native brush canopy, controlling buffelgrass, and re-seeding cleared strips with native forbs and grasses.

2

Erosion control

Re-vegetating caliche pads and senderos, berms on sloping cleared strips, and protecting creek and resaca banks.

3

Predator control

Coyote and bobcat management during fawning, feral hog trapping at water and feed sites, and raccoon control around quail nesting cover.

4

Supplemental water

Wildlife waterers spaced roughly every half-mile in quail country, converting cattle troughs with ramps, and maintaining earthen tanks with shallow edges.

5

Supplemental food

Protein feeding programs for deer, food plots of lablab or cowpeas where rainfall allows, and managing native browse like guajillo and granjeno through brush design.

6

Providing shelter

Retaining dense thornscrub mottes for fawning and thermal cover, leaving brush lines connecting pastures, and protecting old-growth mesquite.

7

Census counts

Helicopter or systematic camera surveys for deer, fall covey counts, spotlight routes, and harvest data logs with age, weight and antler records.

The acreage rule across the South Texas Plains

The ecoregion decides your species and practices. It does not decide your acreage — that comes from a second, legal map: the twelve wildlife appraisal regions of 34 TAC §9.2002. The 23 counties of the South Texas Plains fall into 3 of them, carrying more than one acreage band, so two counties that share every word of their practice standards can carry different minimums:

Wildlife appraisal regions and acreage bands covering the South Texas Plains ecoregion
TPWD wildlife appraisal regionAcreage bandSouth Texas Plains counties
South Texas Plains 25–50 acres 96–98% 13 — Atascosa, Dimmit, Duval, Frio, Jim Hogg, La Salle, and 7 more
Gulf Prairies and Marshes (Lower Coast) 25–50 acres 96–98% 7 — Brooks, Cameron, Hidalgo, Jim Wells, Kenedy, Kleberg, and 1 more
Post Oak Savannah 12.5–16.7 acres 92–94% 3 — Bee, Karnes, Wilson

None of it applies unless the tract was reduced in size since January 1 of the preceding year. If it was, the minimum is 12.5–50 acres depending on the county, and 8 of the 23 districts here have published the exact figure they adopted. See the county-by-county table →

South Texas Plains questions

South Texas Plains wildlife management FAQ

What are the wildlife management intensity standards for the South Texas Plains?
TPWD publishes Comprehensive Wildlife Management Planning Guidelines for each ecoregion, and your appraisal district measures your plan against the South Texas Plains edition. Intensity is the part landowners underestimate: it is not enough to name a practice, you have to do it at the scale the region expects — a stated number of brush acres, water sites, nest structures or survey nights, sustained annually. The seven worked examples above are written at that scale. The practical test is whether a chief appraiser reading your plan can tell how much of each practice you committed to, and whether your records show you did it.
Which species should a South Texas Plains wildlife management plan target?
Whatever you name, it has to be indigenous — Texas Tax Code §23.51(7) qualifies land used to sustain a breeding, migrating or wintering population of native wild animals, and that is the species test that decides qualification. In the South Texas Plains, plans are usually built around trophy white-tailed deer, bobwhite quail, Rio Grande turkey, javelina, chachalacas in the Valley, and ocelots in remnant thornscrub. South Texas grows the biggest whitetails in the state on native thornscrub browse; strip-pattern brush management that keeps 40–60% canopy is the signature habitat practice of the region. Introduced species are the common trap, so confirm every species you name in the plan is native to Texas before you file — managing for exotics (alone) earns nothing toward your three practices.
What is the minimum acreage in the South Texas Plains?
For most tracts, none at all — an acreage test applies only where the tract was reduced in size since January 1 of the preceding year. And when it does apply, it is not the ecoregion that decides it: the 23 South Texas Plains counties fall into 3 different TPWD wildlife appraisal regions, whose bands run from 12.5 to 50 acres. 8 of the 23 districts here have published the figure they adopted; the rest have not, and their county falls back to its band. See the figure for every county.
Which counties are in the South Texas Plains?
23 of Texas's 254: Atascosa, Bee, Brooks, Cameron, Dimmit, Duval, Frio, Hidalgo, Jim Hogg, Jim Wells, Karnes, Kenedy, Kleberg, La Salle, Live Oak, Maverick, McMullen, Starr, Webb, Willacy, Wilson, Zapata, Zavala. Each has its own guide covering the appraisal district, the filing calendar, and the acreage rule as it applies there. Texas ecoregions do not follow county lines, so a county on a boundary may read as South Texas Plains on one side and something else on the other — where a district's own guidance points elsewhere, follow the district.
Which three practices should a South Texas Plains plan start with?
Habitat control, supplemental water, and census counts is the combination that works almost everywhere, and it works here: habitat control is where the real management happens, water is the easiest to install and photograph, and a census produces dated evidence every year without fail. In the South Texas Plains that means strip or mosaic brush sculpting that retains 40–60% native brush canopy, controlling buffelgrass, and re-seeding cleared strips with native forbs and grasses. You need three of the seven each year, and you may change which three as the land changes — the requirement is three practices performed and documented, not three particular practices forever.
