The wildlife exemption in Mason County
In Mason County, more landowners convert to wildlife management every year - keeping the low taxes of an ag valuation while managing white-tailed deer and Rio Grande turkey instead of cattle. The county lies in the Edwards Plateau ecoregion, and that shapes exactly what your management plan should look like.
The Edwards Plateau - the Texas Hill Country - is a limestone tableland of live oak and ashe juniper savannah, cut by spring-fed creeks and steep canyons. Decades of overgrazing and juniper encroachment have degraded native grasslands here, which is exactly why wildlife management practices like brush control and native grass restoration carry so much weight with appraisal districts in this region.
The Edwards Plateau supports some of the densest white-tailed deer populations in North America - often exceeding one deer per 8–10 acres - which makes census counts and habitat management especially meaningful here. Typical target species for Mason County plans include white-tailed deer, Rio Grande turkey, bobwhite quail, black-capped vireo, golden-cheeked warbler, and a wide range of native songbirds and pollinators. The recurring habitat challenges - juniper (cedar) encroachment, overbrowsing by high deer densities, and declining spring flows - are what a good management plan turns into qualifying work.
On the ground in Mason County
Mason County mixes granite and limestone, live oak savanna, native grass, rocky creeks and Llano-system country in a way that feels different from the cedar-heavy Hill Country farther southeast. The old ranch landscape is still relatively intact around Mason, which makes preserving the existing mosaic as important as adding anything new. Selective juniper or brush work, native-grass recovery, creek protection, dependable water and repeatable deer or bird census can all fit. A wildlife plan for Mason County needs to use the property’s geology and oak structure to decide where opening, cover and water belong.
Mason County lies in the Edwards Plateau and is assigned to TPWD's Edwards Plateau (Eastern) wildlife-use appraisal region - the legal map that sets the reduced-tract acreage rule below.
Is there an acreage minimum in Mason County?
Did the tract get smaller since January 1 of last year?
There is no wildlife acreage test in Mason 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 Mason County appraisal district has published its figure. The legal minimum land requirement is 20 acres.

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