As Burmese pythons proceed to eat their means by the South Florida meals internet, wildlife biologists and researchers have give you all kinds of the way to trace down the enormous snakes and gradual their unfold. They’ve used drones, thermal cameras, robotic bunnies, and even male “scout snakes” implanted with GPS gadgets that may make them breeding females. (These scouts have confirmed to be notably efficient in and across the Everglades.)
Now, biologists are engaged on a brand new monitoring instrument: one which has a pouch for younger, a unadorned tail, and a propensity for taking part in lifeless.
The strategy of possum-tracking is being developed on the Crocodile Lake Nationwide Wildlife Refuge close to Key Largo, in line with the South Florida Solar Sentinel. The thought took root in 2022, when Michael Cove, a biologist with the North Carolina Museum of Pure Sciences, was finding out the actions of raccoons and possums within the refuge.
Cove and the refuge supervisor, Jeremy Dixon, saved getting mortality alerts from the GPS-collared mammals. And after they’d exit into the refuge to get well the collars, they’d typically discover them contained in the bellies of enormous pythons. After discovering and euthanizing a number of massive snakes, they’d an thought: Why not use GPS-collared critters as sacrificial python bait?
“We’re not placing these animals on the market and in hurt’s means,” Dixon informed the Sentinel. “Hurt’s means is there. We’re simply documenting what is going on.”
This concept turned extra possible because the GPS collars received cheaper, dropping from roughly $1,500 a collar to round $190 apiece. Cove and Dixon have been capable of safe grant funding from the South Florida Water Administration District, which has its personal python elimination program. In addition they introduced in A.J. Sanjar, a graduate researcher from Southern Illinois College, as a 3rd member of the analysis group.

As they experimented with the concept, they shortly realized that possums have been a lot simpler to work with than raccoons. They’re additionally extra plentiful on the refuge, the place they will go deep into backwater swamps. A few of the collared possums have been eaten by snakes inside two weeks of being launched, and the group has eliminated at the very least 18 Burmese pythons up to now. All of these pythons have been over 8 toes lengthy, and the most important was round 13 toes, in line with Dixon.
The group now has 32 GPS-collared possums out within the refuge, they usually plan to have at the very least 40 animals collared by the height of summer season. Dixon defined that if funding wasn’t a difficulty, they’d have tons of of collared possums within the area.
