The wildlife exemption in Somervell County
The wildlife exemption lets Somervell 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 Cross Timbers & Prairies, TPWD's regional standards for that ecoregion set the bar your plan is judged against.
The Cross Timbers and Prairies region alternates bands of post oak and blackjack oak woodland with limestone prairies, stretching west and south of the DFW Metroplex. It is prime "ranchette" country: properties of 20–200 acres where owners are converting from marginal cattle operations to wildlife management as land prices and fragmentation make grazing impractical.
Deer numbers are strong throughout the Cross Timbers, and Rio Grande turkeys travel the oak creek corridors - properties that protect roost trees and manage brush strategically score well on management plans here. Typical target species for Somervell County plans include white-tailed deer, Rio Grande turkey, bobwhite quail, painted buntings, and mourning dove. The recurring habitat challenges - juniper and mesquite encroachment on prairies, overgrazed rangeland recovering slowly, and rapid fragmentation near the Metroplex - are what a good management plan turns into qualifying work.
On the ground in Somervell County
Glen Rose, the Paluxy and Dinosaur Valley sit in one of Texas’s smallest counties, but the ground is surprisingly varied: limestone hills, oak-juniper cover, prairie openings and Brazos-influenced drainage. On a wildlife-managed tract, the work can restore native grass, thin dense brush selectively, protect the Paluxy and smaller creeks and maintain water across relatively compact tracts. In Somervell County, the plan should feel scaled to a small Cross Timbers county where every connected piece of cover and open forage can matter.
Somervell County lies in the Cross Timbers & Prairies and is assigned to TPWD's Cross Timbers and Prairies wildlife-use appraisal region - the legal map that sets the reduced-tract acreage rule below.
Is there an acreage minimum in Somervell County?
Did the tract get smaller since January 1 of last year?
There is no wildlife acreage test in Somervell 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 Somervell County appraisal district has published its figure. The legal minimum land requirement is 14.34 acres.

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