The wildlife exemption in Calhoun County
Calhoun County land qualifies for the same wildlife management valuation used across Texas - same statute, same forms - but the practices that succeed here are pure Gulf Prairies & Marshes. Get the regional details right and the tax side takes care of itself.
The Gulf Prairies and Marshes hug the Texas coast in a band of tallgrass coastal prairie, old rice fields, and salt marsh. The region funnels the Central Flyway: millions of ducks, geese, and shorebirds winter here, and wetland management - flooding moist-soil units, managing salinity, restoring prairie - is the backbone of most wildlife management plans.
Deer thrive in the brushy uplands and oak mottes behind the marsh; but it is wetland and moist-soil management that appraisal districts most expect to see on coastal management plans. Typical target species for Calhoun County plans include wintering waterfowl, mottled ducks, whooping cranes on the central coast, shorebirds, white-tailed deer, and Attwater’s prairie-chicken on remnant prairie. The recurring habitat challenges - Chinese tallow invasion of prairie, loss of coastal wetlands, deep-soil conversion to development, and saltwater intrusion - are what a good management plan turns into qualifying work.
On the ground in Calhoun County
Port Lavaca, Matagorda and Lavaca Bays, industrial shoreline and a lot of bird life. For a Calhoun County wildlife exemption, the strongest plan often works with tidal and freshwater habitat rather than trying to manufacture upland habitat that the property does not naturally have. Calhoun County’s bays, coastal marshes, prairie and agricultural ground make waterfowl and migratory-bird habitat a natural management focus. Protecting wetland hydrology, maintaining native grass buffers, controlling invasive vegetation and documenting seasonal bird use can be more locally relevant than feeders or brush clearing.
Calhoun County lies in the Gulf Prairies & Marshes and is assigned to TPWD's Gulf Prairies and Marshes (Upper Coast) wildlife-use appraisal region - the legal map that sets the reduced-tract acreage rule below.
Is there an acreage minimum in Calhoun County?
Did the tract get smaller since January 1 of last year?
There is no wildlife acreage test in Calhoun 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 Calhoun County appraisal district has published its figure. The legal minimum land requirement is 16.67 acres (94%). Wildlife management property associations, and land designated as habitat for a special listed species: 11.11 acres (91%).

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