The wildlife exemption in Madison County
Madison County land qualifies for the same wildlife management valuation used across Texas - same statute, same forms - but the practices that succeed here are pure Post Oak Savannah. Get the regional details right and the tax side takes care of itself.
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 Madison 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 Madison County
Madisonville sits on I-45 in rolling Post Oak ranch country where pasture, oak mottes, brushy draws and stock tanks create abundant edge. The habitat work can improve native forage in openings, keep woody travel cover, protect creek bottoms and manage water. The Madison County plan should treat ordinary ranch decisions as the habitat program: where grazing is concentrated, which brush is opened, which rough strips are left intact and how wildlife use is documented over time.
Madison 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 Madison County?
Did the tract get smaller since January 1 of last year?
There is no wildlife acreage test in Madison 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 Madison 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.
One local wrinkle. The Madison County appraisal district publishes a 12.5-acre wildlife floor in its own standards, but that figure is undated - so it reads as a district practice note rather than the reduced-tract test itself. Don’t conclude from it that a split tract under 12.5 acres can’t qualify, or that an unsplit tract can’t convert. See the district’s document.

How it works here
Madison 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 Madison 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, Madison 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.
