What qualifies here
Texas counts the same broad set of agricultural uses everywhere: Cattle, Goats & Sheep, Horses, Poultry, Exotic Animals, Row Crops, Hay Production, Market Garden, Beekeeping, Timber Production, Orchard / Vineyard, Aquaculture. What changes county to county is the degree of intensity each one has to reach.
Grimes CAD publishes the state Form 50-129 without county acreage or stocking numbers, so the figures below are Post Oak Savannah regional defaults.
Minimum acreage and intensity
| Minimum acreage, livestock | 10 acres |
|---|---|
| Minimum acreage, beekeeping | 5 acres |
| Stocking rate, improved pasture | 1 animal unit per 6 acres |
| Stocking rate, native pasture | 1 animal unit per 14 acres |
Stocking rates are the district's starting point, not a guarantee. Soil, pasture condition and the rest of your operation move the number.
Bees
6 hives on the first 5 acres, then 1 more per 2.5 acres up to 20 acres.
Ecoregion default, confirm with Grimes Central Appraisal District.
Beekeeping qualifies on tracts of 5 to 20 acres under Tax Code 23.51. The hive count is set by your appraisal district, not by the state. How beekeeping valuation works.
Wildlife option
Land already under a 1-d-1 agricultural valuation can move to wildlife management and keep the same low value. You file a wildlife management plan on PWD-885 with the application, and you keep managing for the practices the plan names.
Minimum tract if subdivided: 20 acres (12.5 with a wildlife management association).
Ecoregion default, confirm with Grimes Central Appraisal District.
