The wildlife exemption in Terry County
The wildlife exemption lets Terry County landowners hold on to their 1-d-1 agricultural valuation - and its tax savings - by managing land for native species like mule deer and playa waterfowl. Because the county sits in the High Plains, TPWD's regional standards for that ecoregion set the bar your plan is judged against.
The High Plains of the Panhandle and South Plains are flat shortgrass prairie over the Ogallala Aquifer, dotted with more than 19,000 playa lakes - shallow seasonal wetlands that host hundreds of thousands of wintering waterfowl and cranes. Wildlife management here often pairs playa restoration with lesser prairie-chicken, quail, and mule deer habitat work on retired farmland.
Mule deer work the breaks and CRP grasslands while whitetails follow the creek systems; playa lake restoration is among the highest-value practices an appraisal district will see on a High Plains management plan. Typical target species for Terry County plans include mule deer, pronghorn, scaled quail, lesser prairie-chicken, sandhill cranes, native grassland songbirds, and wintering waterfowl on playas. The recurring habitat challenges - playa sedimentation from cropland runoff, declining aquifer and shelterbelts, and conversion of CRP grassland back to row crops - are what a good management plan turns into qualifying work.
On the ground in Terry County
Brownfield sits in sandy southern High Plains country where cotton, oil activity, shinnery-influenced cover and long stretches of open ground create a patchwork rather than one uniform habitat. Wind and drought make ground-cover loss and erosion persistent concerns. On a wildlife-managed tract, the work can retain native shrub and grass blocks, stabilize bare soil, protect field borders and low areas and maintain dependable water. What matters in Terry County is a plan that can use the permanent pieces between production and infrastructure as the habitat network, with census focused on open-country birds or other species the tract can realistically support.
Terry County lies in the High Plains and is assigned to TPWD's High Plains wildlife-use appraisal region - the legal map that sets the reduced-tract acreage rule below.
Is there an acreage minimum in Terry County?
Did the tract get smaller since January 1 of last year?
There is no wildlife acreage test in Terry 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 Terry County appraisal district has not published its exact figure. However, the legal minimum land requirement for this county in the High Plains region is between 25–50 acres (96–98%). 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
Terry 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 High 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 Terry 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 High 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, Terry 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, High Plains-style
These are the kinds of activities appraisal districts in the High Plains recognize as real management - your plan picks at least three. The High Plains region guide covers the species, habitat problems and intensity standards behind them.
