The wildlife exemption in Lavaca County
The wildlife exemption lets Lavaca 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 Post Oak Savannah, TPWD's regional standards for that ecoregion set the bar your plan is judged against.
The Post Oak Savannah rolls between the Blackland Prairies and the Pineywoods - a mosaic of post oak and blackjack oak woodlands, improved pastures, and sandy-loam soils. Much of this region was converted to bermudagrass pasture, so wildlife management here often centers on restoring native plant communities and managing the yaupon understory that shades out forage.
The Post Oak Savannah carries strong and growing deer populations, and its patchwork of woods and pasture makes it one of the most practical regions in Texas to run a credible wildlife management program on 20–100 acres. Typical target species for Lavaca County plans include white-tailed deer, Rio Grande turkey, bobwhite quail, mourning dove, and grassland songbirds. The recurring habitat challenges - yaupon and eastern redcedar encroachment, bermudagrass monocultures with little wildlife value, and habitat fragmentation from subdivision - are what a good management plan turns into qualifying work.
On the ground in Lavaca County
Hallettsville sits in rolling country where Post Oak patches, coastal-prairie influence, improved pasture and the Lavaca/Navidad drainage systems all overlap. The result is a useful habitat mosaic rather than a clean regional boundary. Useful habitat work can restore native grass in low-diversity pasture, retain oak and brush corridors, protect creek bottoms and improve pond or wet-area edges. On Lavaca County ground, the wildlife plan should show how those pieces provide food, cover and water across a working ranch and avoid managing the entire property for one species or one vegetation type.
Lavaca County lies in the Post Oak Savannah and is assigned to TPWD's Post Oak Savannah wildlife-use appraisal region - the legal map that sets the reduced-tract acreage rule below.
Is there an acreage minimum in Lavaca County?
Did the tract get smaller since January 1 of last year?
There is no wildlife acreage test in Lavaca 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.
The Lavaca County appraisal district has not published its exact figure. However, the legal minimum land requirement for this county in the Post Oak Savannah region is between 12.5–16.7 acres (92–94%). If your acreage is inside of this range, we recommend to file the plan either way; the county will apply whatever they adopted.

How it works here
Lavaca 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 Post Oak Savannah 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 Lavaca 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 Post Oak Savannah 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, Lavaca 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, Post Oak Savannah-style
These are the kinds of activities appraisal districts in the Post Oak Savannah recognize as real management - your plan picks at least three. The Post Oak Savannah region guide covers the species, habitat problems and intensity standards behind them.
