Wildfire Risk and Preparedness for Texas Agricultural Operations

Texas recorded more than 9,000 wildfires in a single year during 2022, burning over 680,000 acres according to the Texas A&M Forest Service. For agricultural operations, the math is stark: a single fast-moving grass fire can incinerate a year's worth of hay inventory, kill or injure livestock, destroy fencing across miles of rangeland, and reduce equipment to scrap metal before a county volunteer department can assemble a response. Wildfire risk and preparedness for Texas agricultural operations covers the specific conditions that ignite and spread fires across farmland and ranch country, the tools producers use to assess and reduce that risk, and the decision points that separate recoverable losses from catastrophic ones.

Definition and scope

Wildfire risk, in the agricultural context, is the probability that an uncontrolled fire will ignite on or spread onto a farm or ranch, combined with the potential severity of the resulting damage to crops, livestock, infrastructure, and soil. Texas A&M Forest Service distinguishes between hazard — the physical fuel load, terrain, and weather conditions — and risk, which layers in human activity patterns such as equipment operation, controlled burn escapes, and roadway spark sources.

Texas's Texas Department of Agriculture oversees general agricultural policy, but wildfire suppression and prescribed burn permitting fall under Texas A&M Forest Service jurisdiction and, for prescribed burning, under the Texas State Office of Risk Management framework established by the Texas Prescribed Burning Act (Agriculture Code, Chapter 153).

Scope and coverage limitations: This page addresses wildfire risk within Texas agricultural operations subject to Texas state law and Texas A&M Forest Service guidance. Federal land management protocols — including those administered by the U.S. Forest Service or Bureau of Land Management — are not covered here. Operations in bordering states, even those facing similar ecoregion fire conditions, fall under different regulatory frameworks and are outside this page's scope.

How it works

Fire in Texas agricultural settings follows the same triangle of fuel, heat, and oxygen that governs any combustion, but the agricultural version of that equation has some particular characteristics worth understanding.

Fuel load in farm and ranch settings consists primarily of cured grasses, crop residue, and brush. After extended drought — a recurrent condition across Texas rangelands covered in more detail at Texas Drought and Agriculture — fine fuels cure quickly and become highly flammable. A single acre of dry coastal bermudagrass can carry a fire that moves at 50 to 100 feet per minute under 20-mph wind conditions, according to Texas A&M Forest Service fire behavior modeling resources.

Ignition sources on agricultural operations differ from urban settings. The top sources documented by Texas A&M Forest Service include:

Equipment operation — specifically combines, mowers, and tractors generating sparks against dry crop residue
Escaped prescribed burns — controlled burns that exceed planned perimeters
Debris burning that spreads during wind events
Power line contacts with dry vegetation
Lightning strikes in open pasture during dry thunderstorm events

Spread dynamics depend heavily on the Texas Agricultural Climate and Weather patterns in a given ecoregion. West Texas and the Rolling Plains experience the highest fire weather index days annually, driven by low relative humidity and persistent southwest winds. The Cross Timbers and Post Oak Savanna regions face heavy brush encroachment that creates ladder fuels — a condition where ground-level fire climbs into the tree canopy and becomes dramatically harder to suppress.

Common scenarios

Three fire scenarios account for the largest share of agricultural losses in Texas.

Harvest-season equipment fires peak in June through August across grain-producing regions. A combine cutting dry wheat or grain sorghum can accumulate fine-dust buildup around the engine and cutting deck; that accumulation ignites at temperatures the engine routinely produces. Producers operating in Texas Grain Sorghum Production and Texas Corn and Wheat Farming regions face this risk most acutely. Standard mitigation includes pre-dawn equipment cleaning with compressed air, fire extinguisher mounting directly on the combine cab, and maintaining a disked firebreak on the harvest block perimeter.

Escaped prescribed burns are not rare. The Texas A&M AgriLife Extension Service notes that improper weather window selection accounts for the largest share of escape events — specifically, burns initiated when relative humidity drops below 25% or winds shift unexpectedly. The Texas Prescribed Burning Act requires certified prescribed burn managers for burns conducted under the liability protections of the Act, but many operations still burn without that certification.

Neighbor-origin fires represent a scenario where the affected producer had no ignition role at all. A fire starting along a county road, at a neighboring property, or from a railroad right-of-way can move across property lines in minutes under high fire weather conditions. Defensible space preparation — disked or mowed perimeter buffers, cleared fence lines, maintained access roads — is the primary hedge against this scenario.

Decision boundaries

The clearest decision boundary in wildfire preparedness is whether a producer qualifies losses under a Texas Crop Insurance policy that includes fire coverage, or bears those losses uninsured. USDA Risk Management Agency's Actual Production History (APH) policies cover fire as a named peril for most program crops, but pasture, rangeland, and forage policies function differently and require separate enrollment through the Pasture, Rangeland, and Forage (PRF) program.

A second decision boundary involves prescribed burning. Conducting burns under a certified prescribed burn manager activates liability protections under Agriculture Code §153.082; conducting burns without that certification leaves the landowner fully liable for suppression costs and property damage to neighbors. For operations in the Texas Livestock and Ranching sector where brush management through fire is a core land practice, that certification difference carries significant financial consequence.

A third boundary involves when to self-suppress versus call for help. Texas A&M Forest Service recommends the following rule of thumb for small agricultural fires: if a grass fire cannot be suppressed within the first 60 seconds using on-hand water or hand tools, the correct action is immediate 911 contact and evacuation of livestock from adjacent pens — not continued solo suppression attempts. Fires in fine fuel conditions can double in size every 90 seconds.
