Farmers and land managers across the Southern United States are losing ground to feral swine, a destructive invasive species whose range has expanded steadily since the early 1980s. USDA county-level presence maps now span benchmark years from 1982 through 2025, and they show the animals pushing into new territory despite more than a decade of federally funded removal efforts. The damage goes beyond torn-up crop fields: rooting and wallowing destroy native vegetation, open habitat to invasive plants, and raise disease risks for livestock and wildlife alike.
Why the southward spread of feral swine demands attention in 2026
The core tension is straightforward. Congress created the National Feral Swine Damage Management Program with dedicated funding in fiscal year 2014, giving USDA Wildlife Services a formal mandate to reduce populations and damage. More than a decade later, the animals still occupy an expanding footprint. That gap between federal investment and on-the-ground results shapes every policy debate about how to allocate future removal dollars.
One working hypothesis holds that counties receiving coordinated pilot funding from APHIS and the Natural Resources Conservation Service after 2018 should show slower rates of new feral swine detections on subsequent distribution maps compared with adjacent, untreated counties that have similar habitat. The logic is simple: targeted trapping, aerial gunning, and landowner assistance should suppress local populations faster than they can rebound or spread. Yet the publicly available USDA distribution data track only county-level presence or absence, not density. That binary format makes it difficult to confirm whether treated counties are actually seeing population declines or simply have not yet cleared the threshold for removal from the map.
The practical result for producers is uncertainty. A cattle rancher in east Texas or a row-crop farmer in Alabama can see the damage in real time, but the federal data do not yet offer a county-by-county scoreboard showing whether removal programs are winning or losing.
Federal data and field surveys document the damage trail
The strongest evidence of ongoing harm comes from several federal sources working in parallel. USDA’s Animal and Plant Health Inspection Service publishes county maps covering benchmark years from 1982 through 2025. Those maps confirm a pattern of range expansion that began with escaped domestic pigs and Eurasian boar originally introduced for sport hunting, then accelerated as the animals proved adaptable to nearly any Southern habitat, from bottomland hardwoods to coastal prairies.
The National Wildlife Research Center, the science arm of APHIS, has conducted a multi-state survey covering a 13-state region to estimate annual livestock predation and disease transmission losses tied to feral swine. That work extends the damage picture beyond crops and habitat into direct threats to cattle, goats, and other livestock. The 13-state footprint covers much of the South and parts of the southern Great Plains, where feral swine populations overlap heavily with grazing operations.
At the state level, the Texas Parks and Wildlife Department compiles its own estimates of agricultural losses from feral hogs, drawing on peer-reviewed studies and field data collected across the state. Texas has long been considered the epicenter of the feral swine problem, and TPWD’s damage assessments help calibrate the scale of losses that individual producers face each growing season.
On federal conservation lands, the U.S. Fish and Wildlife Service coordinates removal operations with APHIS, pairing population control with genetic and disease sampling. Those refuge-based projects document how feral swine destroy native vegetation and create wallows that invite invasive plant species, degrading the same habitat that refuges were established to protect.
Gaps in pilot program reporting and disease surveillance
Several important questions remain open. The joint NRCS-APHIS Feral Swine Eradication and Control Pilot Program, authorized by the Farm Bill, has produced a final report, but that document does not release before-and-after economic or habitat metrics from treated sites in a format that allows independent comparison with untreated counties. Without those numbers, the hypothesis that pilot-funded counties show measurably slower spread cannot be confirmed or rejected using public data alone.
Disease surveillance presents a similar gap. USDA’s National Wildlife Disease Program runs a feral swine pathogen monitoring effort in partnership with the damage management program, but county-level detection results and trend tables are not publicly available. Producers and state veterinarians who need to assess local risk are left relying on regional summaries rather than granular data.
The NWRC’s 13-state livestock damage survey, while valuable as a national estimate, does not publish its underlying producer-level dataset or confidence intervals. That makes it hard for researchers or policymakers to break the results down by state or county, or to track whether losses are growing or stabilizing over time.
For farmers and land managers across the South, the practical takeaway is direct. Feral swine populations continue to expand into new counties, and the federal tools designed to slow that expansion have not yet produced publicly measurable results at the local scale. Producers see damage in their own fields, but they cannot easily compare their experience with neighboring counties or evaluate whether participation in a pilot project is changing the trajectory of losses over several years.
How the federal program is structured-and what it can and cannot show
The National Feral Swine Damage Management Program, housed within USDA Wildlife Services, operates through a mix of direct control work, cooperative agreements with states and tribes, and public outreach. According to APHIS, the program targets damage reduction rather than complete eradication in most areas, focusing on high-priority agricultural and natural resource sites. Through this framework, biologists and technicians deploy corral traps, conduct aerial operations where feasible, and provide technical assistance to landowners who are trying to coordinate control across property lines.
Program managers emphasize that feral swine biology works against rapid success. The animals reproduce quickly, can shift their home ranges in response to pressure, and exploit a wide variety of food sources. Even intensive removal in one season may be offset by immigration from neighboring areas if control is not synchronized at a landscape scale. That ecological reality helps explain why a decade of funding has not yet translated into shrinking county-level distribution maps.
At the same time, the program’s reporting structure limits what outside observers can see. Public updates tend to focus on numbers of animals removed or general descriptions of damage reduction, rather than standardized metrics that could be compared across years and regions. Without consistent baselines and follow-up measurements, it is difficult to determine whether similar investments in different counties are yielding similar returns.
APHIS notes that its feral swine efforts are integrated with broader wildlife damage management responsibilities, which means staff and equipment are shared across multiple priorities. That flexibility can be an asset during emergencies, but it also complicates efforts to tie specific budget lines to specific outcomes in feral swine control.
What producers and policymakers need next
For landowners, the most immediate need is practical guidance on where federal help is available and how effective it has been in comparable operations. Simple, accessible summaries of pilot project results-expressed in terms of avoided crop loss, reduced livestock predation, or improved habitat condition-would allow producers to weigh the costs of participation against likely benefits.
For state agencies and conservation groups, finer-scale data on both distribution and disease would support more targeted planning. County-level maps that distinguish between long-established core populations and recent incursions could help prioritize early-response efforts, while transparent disease surveillance results would inform vaccination, testing, and biosecurity decisions in nearby livestock herds.
Policymakers, meanwhile, face choices about whether to expand, refocus, or recalibrate federal spending on feral swine. Clearer performance metrics from the existing program would provide a stronger basis for those decisions than distribution maps alone. Linking investments to measurable reductions in damage-rather than simply tallying animals removed-could sharpen the program’s strategy and improve accountability.
APHIS has signaled an interest in refining its approach, and the agency’s description of its management work highlights ongoing collaboration with states, tribes, and private landowners. Turning that collaboration into a more transparent, data-driven system will be essential if the federal government hopes to slow the spread of feral swine across the Southern landscape and give farmers, ranchers, and wildlife managers a realistic chance to protect the ground they still hold.
