Friday marked the start of the annual Florida Python Challenge, where hunters head into the Everglades to track down invasive Burmese pythons in hopes of grabbing a share of $30,000 in prizes.

The annual 10-day hunt, which started more than a decade ago, promotes public awareness of issues with invasive species in Florida while engaging the public in Everglades conversation, said Sarah Funck, the wildlife impact management section leader with Florida Fish and Wildlife Conservation Commission.

“They are a well-established invasive species across much of South Florida, unfortunately, in our natural areas,” Funck said of Burmese pythons. “A huge part of this challenge is to make sure that people understand about this issue and understand that in general, when you have a non-native species present in the state for whatever purpose, don’t let it loose, that can be really detrimental to our environment.”

Over the past decade, the python challenge has grabbed headlines for it’s incentive-based, only-in-Florida style of hunting as well as celebrity participation. This year, more than 600 people registered for the event, with two coming from Canada and 108 from other states.
