Wildlife management valuation in San Patricio County, Texas
Often searched as the “wildlife exemption” — technically it’s not an exemption at all, but keeping your existing 1-d-1 productivity valuation with wildlife management as the qualifying use. Here is what that takes in San Patricio County.
San Patricio County spans more than one TPWD ecoregion: Gulf Prairies and Marshes (about 78% of the county), South Texas Plains (about 22% of the county). Which guidelines govern your land depends on where your tract sits, not on the county line.

Deadlines that matter in San Patricio County
File between January 1 and April 30 of the tax year: a new 1-d-1 open-space application (Comptroller Form 50-129) with the wildlife management section completed, plus your wildlife management plan (TPWD PWD-885), with the county appraisal district. The plan alone converts nothing — the application does.
Before the deadline passes, the chief appraiser may grant up to 60 extra days for good cause if you ask in writing (Tax Code §23.54(d)) — worth asking before assuming you’re late.
Missed April 30? Late applications are accepted until the appraisal review board approves the appraisal records for the year — with a penalty equal to 10% of the difference between the tax at productivity value and what the tax would have been at market value, i.e. a tenth of that year’s savings (Tax Code §23.541).
San Patricio County’s ARB has typically approved records around July 20, 2026 — verify the current year’s date with the appraisal district before relying on it.

- • Predator control
- • Providing supplemental supplies of water
- • Providing supplemental supplies of food
- • Providing shelters
- • Making census counts to determine population
Region-specific intensity standards for Gulf Prairies and Marshesaren’t in our structured database yet — TPWD’s regional guidelines are the authority until they are.
County lines are not ecoregion lines — your tract’s governing ecoregion resolves from where the land actually sits. The plan wizard does this from your parcel location.
Minimum acreage (the wildlife-use requirement)
This minimum-acreage table only applies if your tract got smaller after January 1 of the preceding tax year (34 TAC §9.2005(b)–(c)). If your acreage is unchanged or larger, there is no wildlife-use requirement to meet — most landowners can skip this section.
| Wildlife-use appraisal region | Standard range | Property-association range |
|---|---|---|
| Gulf Prairies and Marshes (Upper Coast) | 92–94% | 90–91% |
| Gulf Prairies and Marshes (Lower Coast) | 96–98% | 94–95% |
| South Texas Plains | 96–98% | 94–95% |
The rule splits this region into sub-areas with different ranges — both are shown. Which sub-area applies depends on where your tract sits; the chief appraiser then selects the ratio from that sub-area’s range. Your appraisal district can confirm which sub-area covers your land.
Ranges from 34 TAC §9.2005 (Wildlife Use Requirement). Land in TPWD-designated endangered/threatened-species habitat has its own band under subsection (e) — ask the appraisal district if that may apply to you.

Common questions in San Patricio County
How do I switch from ag exemption to wildlife exemption in San Patricio County?
Both are 1-d-1 open-space valuations, not true exemptions. Converting means filing a new 1-d-1 application (Form 50-129) with the wildlife-management section completed, plus a wildlife management plan (TPWD PWD-885), with the appraisal district between January 1 and April 30. Your land must already hold 1-d-1 (or timber) valuation, and wildlife management must become its primary use. Because San Patricio County spans ecoregions, your plan follows the guidelines for where your tract sits.
Do my property taxes change when I convert to wildlife management use?
Conversion keeps your existing 1-d-1 productivity valuation with wildlife management as the qualifying use — it is designed to be tax-neutral relative to your current ag valuation. The chief appraiser makes every valuation decision; no software or consultant can promise an outcome.
How many wildlife management practices do I need in San Patricio County?
At least 3 of the 7 statutory practices; many landowners commit to 5 or more for margin. Practices come with region-specific intensity standards — TPWD’s regional guidelines set the standards for Gulf Prairies and Marshes.
What is the minimum acreage for wildlife management use in San Patricio County?
There is no blanket statewide minimum. A minimum-acreage test (the wildlife-use requirement) applies only if your tract was reduced in size after January 1 of the preceding tax year; otherwise the requirement does not apply at all. If it does apply, the appraisal district picks a ratio from the range set for this wildlife-use appraisal region — the ranges for this county are on this page.
What if I miss the April 30 deadline in San Patricio County?
Ask about the good-cause extension first: before the deadline the chief appraiser may grant up to 60 extra days on written request. After that, late applications are accepted until the ARB approves the appraisal records — see the date above — with a penalty of 10% of that year’s tax savings.
