Burmese Pythons have already invaded Florida’s Everglades, and have now been found in south Georgia Swamps.
Even without a warming planet, this invasive predator can live comfortably in a third of the southern United States.
Pythons have been documented in two states, and may have invaded more areas, but have just not been officialy
recognized yet. These snakes are a dangerous constrictor that grows up to twenty feet in lenth, making them capable
of eating fairly large animals, such as dogs, calves, ‘coons, ‘possums, and human children, or even small adults. Though
not fanged like rattlers they do have lots of back pointing teeth which they use to secure prey while constricting. These
are teeth that don’t get brushed or flossed and leave a nasty septic wound that needs treatment… if the prey (us) manages to get loose.
I don’t know if there is an open season on hunting and/or trapping/killing pythons, or if there may even be a bounty. Hunting and Fishing laws are different in each state, so before you decide to eradicate pythons, you best see what is legal and what is recommended. ‘Cause I don’t know.
Python Snakes, An Invasive Species In Florida, Could Spread To One Third Of US
ScienceDaily (Feb. 24, 2008) — Burmese pythons—an invasive species in south Florida—could find comfortable climatic conditions in roughly a third of the United States according to new “climate maps” developed by the U.S. Geological Survey (USGS). Although other factors such as type of food available and suitable shelter also play a role, Burmese pythons and other giant constrictor snakes have shown themselves to be highly adaptable to new environments.
The just-released USGS maps can help natural resource agencies manage and possibly control the spread of non-native giant constrictor snakes, such as the Burmese python, now spreading from Everglades National Park in Florida. These “climate match” maps show where climate in the U.S. is similar to places in which Burmese pythons live naturally (from Pakistan to Indonesia).
A look at the map shows why biologists are concerned.
The maps show where climate alone would not limit these snakes. One map shows areas in the U.S. with current climatic conditions similar to those of the snakes’ native ranges. A second map projects these “climate matches” at the end of this century based on global warming models, which significantly expands the potential habitat for these snakes.
Biologists with Everglades National Park confirmed a breeding population of Burmese python in the Florida Everglades in 2003, presumably the result of released pets. Python populations have since been discovered in Big Cypress National Preserve to the north, Miami’s water management areas to the northeast, Key Largo to the southeast, and many state parks, municipalities, and public and private lands in the region.
“Wildlife managers are concerned that these snakes, which can grow to over 20 feet long and more than 250 pounds, pose a danger to state- and federally listed threatened and endangered species as well as to humans,” said Bob Reed, a USGS wildlife biologist at the Fort Collins Science Center in Colorado, who helped develop the maps. “Several endangered species,” he noted, “have already been found in the snakes’ stomachs. Pythons could have even more significant environmental and economic consequences if they were to spread from Florida to other states.”
Control of exotic species is often prohibitively expensive once they have become established. Therefore, prevention through screening and risk assessment is of great importance, especially when protecting continental areas from invasive reptiles, said USGS invasive snake expert Gordon Rodda, also of the Fort Collins center. USGS scientists and their partners are seeking to compile the scientific data necessary to guide management efforts to prevent further introductions, control existing populations of snakes, and contain their spread.
Burmese pythons have been found to eat endangered Key Largo woodrats and rare round-tailed muskrats. “This makes it that much more difficult to recover these dwindling populations and restore the Everglades,” said park biologist Skip Snow, “and all the more important that pet owners be responsible in their choice of pet and dispose of it properly should they need to. Releasing them into the environment is bad for that pet, bad for native species, and also illegal.”
Currently, scientists with the USGS and Everglades National Park are investigating the behavior and biology of these snakes – that is, what are their requirements for survival? This information will help refine predictions of where the snakes might go next and their likelihood of survival. USGS researchers are also conducting a risk assessment for nine species of giant constrictors (including boa constrictors and yellow anacondas) that are prevalent in the pet trade and as such, potential invaders in the United States.
Due to be completed by early 2009, the assessment evaluates the risk of invasion for these species and the potential for social, economic, and environmental impacts. The two agencies are also developing and testing tools to control invasive snake populations and prevent their spread, especially to the Florida Keys where several listed species would be threatened by the presence of pythons or other constrictors.
