Florida’s long fight against invasive Burmese pythons produced a grim milestone this year, as a single conservation team in one southwest county hauled roughly four tons of the giant snakes out of the ecosystem in a single season. The figure, a record for the group that logged it, is both a measure of success in catching the reptiles and a stark reminder of just how deeply entrenched they have become in the state’s wetlands. Each ton removed represents hundreds of animals that would otherwise be eating their way through native wildlife.
The pythons are not native to Florida. They descend from released or escaped pets that established a breeding population in the Everglades decades ago, and they have since spread across a vast swath of the southern peninsula. With no natural predators large enough to keep them in check, the snakes have multiplied into a self-sustaining invasion that scientists now treat as one of the most damaging in the country.
A record season in Collier County
The haul was reported by the Conservancy of Southwest Florida, whose python program removed 177 snakes from a 200-square-mile study area in Collier County over a season running from late 2025 into the spring. Together the captured animals weighed a combined 8,080 pounds, roughly four tons, the greatest biomass the group has pulled from the landscape in a single season since it began the effort in 2013. The Conservancy described the total as evidence that its science-driven approach is reaching deeper into the breeding population than before.
The largest female captured during the season weighed 153 pounds and stretched 17 feet, a size that illustrates why the species is so difficult to manage. A snake that large can consume prey up to the size of a deer, and a single female can carry dozens of developing eggs. Beyond the adult snakes, the team also removed about 4,100 python eggs from the ecosystem, cutting off a substantial portion of the next generation before it could hatch.
How scout snakes lead searchers to the rest
The key to the Conservancy’s approach is a technique built around what researchers call scout snakes. Biologists implant radio transmitters in about 40 male Burmese pythons and release them, then track their movements during the breeding season. Because males actively seek out females to mate, following a tagged scout often leads the team to one or more large, reproductive females that would be nearly impossible to find otherwise in dense, waterlogged terrain.
That method turns the snakes’ own biology against them. Rather than searching blindly across hundreds of square miles of sawgrass and swamp, the team lets the scouts narrow the search to the animals that matter most for population control: the breeding females that drive future generations. Removing those females, along with their eggs, has a far larger effect on the population than catching an equivalent weight of smaller, younger snakes. The scale of this year’s totals was detailed by local coverage of the program’s results.
Why the pythons do so much damage
Burmese pythons are ambush predators, and in Florida they have found an environment full of prey that never evolved defenses against them. Studies in the Everglades have documented sharp declines in marsh rabbits, raccoons, opossums, foxes, and wading birds in areas where the snakes are established. The reptiles consume mammals, birds, and even alligators, and their appetite ripples outward through the food web, affecting the predators and scavengers that once relied on the animals now being eaten.
Their success comes down to a combination of size, camouflage, and reproductive output. A well-fed female can lay a large clutch of eggs, the snakes blend almost perfectly into vegetation and water, and they thrive in the warm, wet conditions that dominate south Florida. Those same traits make them extraordinarily hard to detect, which is why removal totals, however large, still capture only a fraction of the animals believed to be out there.
What a four-ton season really measures
Since 2013, the Conservancy says it has removed more than 20 tons of Burmese pythons from its study area alone, and this year’s four-ton season pushed that cumulative figure higher. Officials frame the numbers as progress, but they are careful not to describe the problem as solved. Removing record weights of snakes demonstrates that the tracking methods work; it does not mean the invasion is shrinking overall, because reproduction continues across a range far larger than any single team can patrol.
The broader lesson from the season is about persistence. Wildlife managers across Florida rely on a mix of tools, from telemetry programs and professional contractors to public removal events, and none of them alone can reverse an invasion this large. A four-ton haul is a sign that the most effective techniques are being pushed to their limits, and a signal that the pythons remain abundant enough to keep filling the traps year after year.
