A new TV show is shedding light on how invasive a snake is doing to Florida’s ecosystems.
What’s going on?
ABC’s “Wildlife Nation: Expedition Florida” examined Burmese pythons in a recent episode. The researchers were able to find an old nest of eggs, where they could describe the scene.
“First of all, they’re incredibly protective. You don’t want to mess with a mom python,” said host Jeff Corwin.
They went on to describe how snakes, which generally do not produce much of their own heat, actually squirm in order to keep the eggs warm and incubate them in a tight clutch. Burmese pythons lay between 12 and 36 eggs each spring.
Why are Burmese pythons important?
The researchers on the show are quick to point out that Burmese pythons are a huge problem in Florida. As apex predators, their eggs face no serious predators, allowing their young to spread unopposed.
Burmese pythons are considered one of the most invasive species (if not the best) in Florida. They were originally introduced into the wild in the state through the exotic pet trade, and the species has since outcompeted all native animals for vital resources.
The result was a 99% decline in raccoon and opossum populations, and an 88% decline in bobcats. Swamp rabbits, cottontail rabbits, and foxes have disappeared from the state entirely, according to the United States Geological Survey.
Florida’s climate allows pythons to live for years, while states that have colder winters are inhospitable. As average daily temperatures increase worldwide due to pollution, however, the range of areas where Burmese pythons can live and reproduce may expand further into the country.
The reduction in biodiversity caused by invasive species incurs severe losses in ecosystem services. Some studies have suggested that over 50 years, invasive species have created costs of more than a trillion dollars globally.
What is being done about Burmese pythons?
Florida has invested millions to eradicate Burmese pythons. Some partners were trying to commercialize the activity by harvesting snake skins and making finished products with them.
If you are interested in the fight against invasive species in your area, it is possible to take local action with volunteer groups that work to remove offending fauna and flora, and introduce a greater range of native species.
