The wildlife exemption in Martin County
Martin County sits in the heart of the High Plains - shortgrass prairie, playa lakes, and mule deer country on the Llano Estacado. For landowners here, the 1-d-1 wildlife management valuation is the most practical way to keep agricultural-level property taxes without running livestock.
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 Martin 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 Martin County
Martin County sits on the seam between southern High Plains agriculture and the Permian Basin, so cotton fields, dry rangeland, caliche roads and energy infrastructure can all share the same view. Wildlife habitat often survives in the pieces between disturbances: native grass and shrub patches, shallow draws, field borders and dependable water. Management can protect and reconnect those areas, stabilize eroding ground and retain cover around roads or pads. In Martin County, the plan should look like practical habitat work inside a working industrial-agricultural landscape, not a generic West Texas ranch description.
Martin 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 Martin County?
Did the tract get smaller since January 1 of last year?
There is no wildlife acreage test in Martin 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 Martin 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
Martin 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 Martin 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, Martin 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.
