The wildlife exemption in Galveston County
Galveston 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 Galveston 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 Galveston County
Galveston Island is not where most qualifying wildlife acreage sits. The more plausible tracts are on the mainland - Santa Fe, Hitchcock and the remaining coastal prairie between the bay system and Houston’s southern edge. On that ground, wetland hydrology, native coastal vegetation, invasive control, nesting cover and seasonal bird census make far more sense than ranch-country brush work. On Galveston County ground, the plan should feel like management of scarce coastal prairie and wet ground inside one of the state’s most developed coastal counties.
Galveston 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 Galveston County?
Did the tract get smaller since January 1 of last year?
There is no wildlife acreage test in Galveston 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 Galveston County appraisal district has not published its exact figure. However, the legal minimum land requirement for this county in the Gulf Prairies and Marshes (Upper Coast) region is between 12.5–16.7 acres (92–94%). 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
Galveston 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 Galveston 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, Galveston 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.
