The wildlife exemption in Collin County
The wildlife exemption lets Collin County landowners hold on to their 1-d-1 agricultural valuation - and its tax savings - by managing land for native species like grassland songbirds and white-tailed deer. Because the county sits in the Blackland Prairies, TPWD's regional standards for that ecoregion set the bar your plan is judged against.
The Blackland Prairies run in a crescent from the Red River through Dallas to San Antonio - deep, fertile black clay that once grew tallgrass prairie and now grows subdivisions and row crops. Less than one percent of the original tallgrass remains, which makes prairie restoration on Blackland properties both ecologically important and highly credible with appraisal districts.
Deer populations in the Blacklands concentrate along creek corridors and remaining woodlands; many successful wildlife management programs here focus on grassland birds and pollinators rather than deer alone - a fully qualifying approach under 1-d-1. Typical target species for Collin County plans include white-tailed deer, bobwhite quail, grassland songbirds like meadowlarks and dickcissels, waterfowl on stock tanks, and native pollinators. The recurring habitat challenges - near-total loss of native tallgrass prairie, johnsongrass and KR bluestem invasion, and intense development pressure - are what a good management plan turns into qualifying work.
On the ground in Collin County
The prairie is mostly gone. Collin County’s remaining agricultural land is under intense Dallas-area development pressure, and much of it sits on historically Blackland Prairie soils. For wildlife, restoring native grass and forbs, protecting creek corridors and keeping broad unmowed field margins can be more meaningful than planting trees everywhere. A plan for Collin County needs to treat remnant prairie and riparian habitat as scarce assets and scale management realistically for fragmented exurban tracts.
Collin County lies in the Blackland Prairies and is assigned to TPWD's Blackland Prairie wildlife-use appraisal region - the legal map that sets the reduced-tract acreage rule below.
Is there an acreage minimum in Collin County?
Did the tract get smaller since January 1 of last year?
There is no wildlife acreage test in Collin 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 Collin County appraisal district has published its figure. The legal minimum land requirement is 16.67 acres (94%). Wildlife management property associations: 11.11 acres (91%).

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