The wildlife exemption in Sutton County
The wildlife exemption lets Sutton 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 Rio Grande turkey. Because the county sits in the Edwards Plateau, TPWD's regional standards for that ecoregion set the bar your plan is judged against.
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 Sutton 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 Sutton County
Sonora sits on I-10 in dry western Edwards country of rocky plateau, karst terrain, live oak, juniper and long draws shaped by a long sheep-and-goat history. Surface water is scarce enough that distribution of dependable wildlife water can change how a ranch is used. Habitat work can also open selected dense woody cover, protect native grass and forbs, repair erosion and retain enough shelter for travel and thermal cover. The Sutton County plan should be drought-first and range-scale, with repeatable deer or other census work tied to those changes.
Sutton County lies in the Edwards Plateau and is assigned to TPWD's Edwards Plateau (Western) wildlife-use appraisal region - the legal map that sets the reduced-tract acreage rule below.
Is there an acreage minimum in Sutton County?
Did the tract get smaller since January 1 of last year?
There is no wildlife acreage test in Sutton 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 Sutton County appraisal district has not published its exact figure. However, the legal minimum land requirement for this county in the Edwards Plateau (Western) 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
Sutton 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 Sutton 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, Sutton 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.
