"A study from the U.S. Geological Survey called the state’s python problem “one of the most intractable invasive-species management issues across the globe.”"
"MIAMI — So much for all the efforts to slow the proliferation of Burmese pythons in the Florida Everglades over the last two decades, including with paid contractors, trained volunteers and an annual hunt that has drawn participants from as far as Latvia: The giant snakes have been making their way north, reaching West Palm Beach and Fort Myers and threatening ever-larger stretches of the ecosystem.
That was one of the few definitive conclusions in a comprehensive review of python science published last month by the U.S. Geological Survey, which underscored the difficulty of containing the giant snakes since they were first documented as an established population in the state in 2000.
Little is known about how long Burmese pythons live in the wild in Florida, how often they reproduce and especially how large the state’s python population has grown, according to the review, which called the state’s python problem “one of the most intractable invasive-species management issues across the globe.”
Nor is it known how exactly they travel. The review theorized that South Florida’s extensive network of canals and levees “may facilitate long-distance movement by pythons,” though it suggested that slithering and swimming to points north may take awhile."
