The wildlife exemption in McLennan County
McLennan County sits in the heart of the Blackland Prairies - deep black clay soils and tallgrass prairie remnants in the fastest-growing corridor in Texas. For landowners here, the 1-d-1 wildlife management valuation is the most practical way to keep agricultural-level property taxes without running livestock.
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 McLennan 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 McLennan County
Waco sits on the Brazos where Blackland farm ground, river corridors and rapidly developing rural acreage all meet. Outside the city, a qualifying tract may contain cultivated fields, pasture, creek bottoms and remnant prairie within a surprisingly small area. Here, wildlife management can restore native grass, protect Brazos or tributary buffers, control invasive vegetation and keep habitat connected across smaller parcels. In McLennan County, the most convincing plan is one that treats prairie, farm edge and river cover as parts of the same landscape rather than borrowing a Hill Country cedar prescription.
McLennan 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 McLennan County?
Did the tract get smaller since January 1 of last year?
There is no wildlife acreage test in McLennan 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 McLennan County appraisal district has not published its exact figure. However, the legal minimum land requirement for this county in the Blackland Prairie 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
McLennan 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 McLennan 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, McLennan 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.
