The wildlife exemption in Grimes County
The wildlife exemption lets Grimes 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 Grimes 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 exactly the problems a good management plan turns into qualifying work.
How it works here
Grimes 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 Grimes 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 was reduced in size in the past year — then the county's wildlife-use ratio sets one (commonly in the 12–50 acre range across Texas; confirm locally before planning a small tract).
