Invasive species surveillance and control is front and center for Crocodile Lake National Wildlife Refuge in the Florida Keys. Just a short 18 mile drive north is the Florida Everglades, where invasive pythons are wreaking havoc on the ecosystem, a situation that would have devastating effects on endangered Keys fauna if the species were to take hold. Indeed, several pythons (one measuring 16 feet long) have already been discovered in the refuge and removed. Learn more...

Giant salvinia is an invasive floating fern from Brazil. The plant spreads vegetatively, from whole plants or plant fragments. Giant salvinia can double its surface acreage in less than one week. It has been spreading and causing problems in coastal Louisiana since 1989. Giant salvinia tends to accumulate in small ponds or areas lacking water exchange. Once it covers the water’s surface, this floating plant will begin to stack up upon itself, and can extend 12 inches or more above the water surface. Learn more...

Thomaston, Georgia — Rule 1 in the art of angling: You have to master the worm. “Ewww!” The teen holding the fishing rod recoiled at the sight of a wad of wigglers. “No. Uh-uh!” — that, from a buddy peering over his shoulder. And a third reaction, courtesy of a fellow who stood 6-foot-2 or more: “I ain’t touching that!” Thus did the guys from the city get introduced to a bit of country. Learn more...

Giant salvinia is an invasive floating fern from Brazil that can double its surface acreage in less than one week in optimal conditions. It has been spreading and causing problems in coastal Louisiana since 1989. Once it covers the water’s surface, this floating plant will begin to stack up upon itself, and can extend 12 inches or more above the water surface. Under such conditions, oxygen recharge of underlying waters is greatly reduced. Learn more...

They are an invasive species that can disrupt entire food chains. “They’re really bad for the ecosystem,” said Craig Sasser, refuge manager at Waccamaw National Wildlife Refuge in South Carolina.

Eastport, Mississippi — This stretch of the Tennessee River is considered the most aquatically biodiverse in the nation, teeming with sportfish and at-risk snails and mussels. Locals boast that Pickwick Lake, where Mississippi, Alabama and Tennessee come together, is “the smallmouth bass capital of the world.” Catfish and buffalo fill commercial angler’s nets. Marinas lining the reservoir’s roads attest to Pickwick’s huge economic impact. Yet the Tennessee River, and a way of life, is under siege. Learn more...

Washington – Today, the U.S. Geological Survey (USGS), U.S. National Park Service (NPS), U.S. Fish and Wildlife Service (FWS) and Conservancy of Southwest Florida announced they have teamed up to radio-track Burmese pythons in Big Cypress National Preserve, Crocodile Lake National Wildlife Refuge and other areas of Southwest Florida. This new effort marks the first-time pythons are being tracked in so many different habitats to better understand python biology across the region and ultimately find ways to more effectively control this invasive species.
