The wildlife exemption in Karnes County

The wildlife exemption lets Karnes County landowners hold on to their 1-d-1 agricultural valuation - and its tax savings - by managing land for native species like white-tailed deer and bobwhite quail. Because the county sits in the South Texas Plains, TPWD's regional standards for that ecoregion set the bar your plan is judged against.

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 Karnes County plans include trophy white-tailed deer, bobwhite quail, Rio Grande turkey, javelina, chachalacas in the Valley, and ocelots in remnant thornscrub. The recurring habitat challenges - buffelgrass monocultures displacing native forage, drought cycles, and clearing that removes too much thermal cover - are what a good management plan turns into qualifying work.

On the ground in Karnes County

Karnes City and Kenedy sit in Eagle Ford country where sandy post oak, prairie and South Texas brush overlap. Energy infrastructure adds another layer to the habitat pattern. The work can restore native grass, keep brush and oak cover in connected blocks, protect creek bottoms and maintain water while repairing or buffering disturbed ground around roads and pads. The Karnes County wildlife plan should use that transition landscape rather than forcing the property into either pure Post Oak or deep-brush South Texas.

Karnes County reads as South Texas Plains habitat on the ground, but TPWD assigns it to the Post Oak Savannah wildlife-use appraisal region for reduced-tract acreage rules - two different maps, and the legal one controls the numbers below.

Is there an acreage minimum in Karnes County?

Did the tract get smaller since January 1 of last year?

No ➔

There is no wildlife acreage test in Karnes County at all. Whatever the size, file Comptroller Form 50‑129 with a PWD‑885 plan. A 7-acre tract that already carried 1‑d‑1 (ag exempt) and was never split can convert with no penalties.

Yes ➔

The Karnes County appraisal district has published its figure. The legal minimum land requirement is 16.67 acres (94%). Wildlife management property associations: 11.11 acres (91%).

How it works here

Karnes County follows the statewide 1-d-1 framework (Texas Tax Code §23.51(7)); the local variables are your appraisal district's filing habits and the South Texas Plains intensity standards:

  • Start from an existing ag or timber valuation. Wildlife management is a conversion of qualified open-space land - check eligibility if your status is unclear.
  • File a wildlife management plan (TPWD form PWD‑885) with the Karnes County appraisal district, attached to Comptroller Form 50‑129, between January 1 and April 30. What goes in the plan →
  • Perform at least 3 of the 7 practices each year at South Texas Plains intensity levels - see the local examples below.
  • Document everything - dates, photos, quantities. When the chief appraiser requests an annual report (PWD‑888), you'll answer with records, not recollections.
  • No minimum acreage applies unless your tract got smaller since January 1 of last year. If it did, Karnes County's figure is covered above - the district picks one number for the whole county, and the plan is still the application either way.

The 7 practices, South Texas Plains-style

These are the kinds of activities appraisal districts in the South Texas Plains recognize as real management - your plan picks at least three. The South Texas Plains region guide covers the species, habitat problems and intensity standards behind them.

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 cost of letting it slip

Losing qualification means market-value taxes going forward - and if the land's use changes to non-agricultural, rollback taxes: the previous three years of tax savings, recaptured in one bill. On typical Karnes County acreage that's easily five figures. How rollback works →

Karnes County questions

Karnes County wildlife exemption FAQ

The questions Karnes County landowners ask most - answered against this county’s appraisal district and the South Texas Plains standards its plans are judged by.

How many acres do you need for a wildlife exemption in Karnes County?
For most tracts, there is no minimum at all. Karnes County applies no acreage test to wildlife management use unless your tract was reduced in size since January 1 of the preceding year. If it was, the Karnes County appraisal district applies the figure it has adopted: 16.67 acres (94%). The district sets 11.11 acres (91%) for land in a wildlife management property association. A tract that was never split can convert at any size, so long as it already carries a 1‑d‑1 (ag exempt) valuation. Source: Karnes County Appraisal District Agricultural Use and Intensity Standards, May 11, 2022.
What is the wildlife exemption filing deadline in Karnes County?
April 30. The window opens January 1 and closes April 30 - file Comptroller Form 50‑129 with a TPWD PWD‑885 wildlife management plan attached at the Karnes County appraisal district in Karnes City. Miss it and the district still accepts a late application until the appraisal roll certifies (typically mid-July), but with a 10% penalty on that year’s tax savings. One trap catches new owners every year: buying land that already holds the valuation does not carry it over to you - you have to file your own application.
Do I need an existing ag exemption to get a wildlife exemption in Karnes County?
Yes. Wildlife management is a qualifying use within the 1-d-1 open-space valuation, not a separate exemption - so the land has to already carry an agricultural or timber productivity valuation on the day you convert. If it does, converting changes the qualifying activity and nothing else: the productivity value carries over from your previous ag category, so your tax bill does not move. If the land lost its valuation, you would requalify the ordinary way first - agricultural use for 5 of the preceding 7 years - and then convert. The conversion playbook →
Which wildlife management practices qualify in Karnes County?
Any three of the seven named in Texas Tax Code §23.51(7): habitat control, erosion control, predator control, supplemental water, supplemental food, providing shelter, and census counts. The list is statewide, but the standard you are judged against is regional - Karnes County is South Texas Plains country, so the Karnes County appraisal district expects work sized to South Texas Plains intensity levels and aimed at the problems that actually limit wildlife here: buffelgrass monocultures displacing native forage, drought cycles, and clearing that removes too much thermal cover. Habitat control, supplemental water, and census counts are the most common opening three. See what each one looks like here →
What species should a Karnes County 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 actually 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: exotics like axis deer or blackbuck may live on the property, but managing for them (alone) earns you nothing toward your three practices - so confirm every species you name in the plan is native to Texas before you file.
Does Karnes County require a PWD-888 annual report every year?
The chief appraiser may require one whenever they ask - that is the statutory standard, and many Texas districts ask annually or on a review cycle. The practical answer is to assume it is coming: keep dated records, photos, and quantities for every practice as you go, and the report is a formality instead of a scramble. Landowners rarely lose a valuation because the work was not done; they lose it because the work could not be proven. What a strong PWD‑888 looks like →
Will switching from cattle to wildlife trigger rollback taxes in Karnes County?
No. Rollback under Texas Tax Code §23.55 is triggered by a change to a non-agricultural use - developing, paving, or subdividing the land. Moving from grazing to wildlife management is a change of use within 1-d-1, so the valuation continues uninterrupted and no recapture is owed. What does carry risk is letting the land go idle: land quietly used for nothing agricultural can be treated as having changed use. A documented wildlife plan is precisely how you stay out of that gray zone. How rollback works →
Who approves the wildlife exemption in Karnes County - TPWD or the appraisal district?
The appraisal district. The Karnes County appraisal district’s chief appraiser reviews your Form 50‑129 and PWD‑885 plan and decides whether the land qualifies, the same as for any agricultural application. Texas Parks & Wildlife publishes the forms and the ecoregion guidelines your plan should match, but it does not approve individual properties and has no vote on your valuation. The district is headquartered in Karnes City; current contact details are in the Texas Comptroller’s county directory.
