South Carolina Department of Natural Resources officials are warning anglers that if the invasive Northern snakehead fish is caught in the Palmetto State, anglers should kill it immediately and by all means NOT release it back into the water. In early October, a Georgia angler reported catching a Northern snakehead, an aquatic invasive species, in a pond located on private property in Gwinnett County, Ga. This is the first time the Northern snakehead has been confirmed in Georgia waters. In the Southeast, Northern snakeheads have also been found in North Carolina and Florida. If you believe you have caught a Northern snakehead:

• DO NOT RELEASE IT
• Kill it immediately (remember, it can survive on land) and freeze it.
• If possible, take pictures of the fish, including closeups of its mouth, fins and tail.
• Note where it was caught (waterbody, landmarks or GPS coordinates).
• Report it to the SCDNR by calling 1-800-922-5431.

In response to the harmful impacts invasive species have on the Nation’s natural and cultural resources, the Department of the Interior released an interdepartmental report, Safeguarding America’s Lands and Waters from Invasive Species: A National Framework for Early Detection and Rapid Response. The report proposes to stop their spread through early detection and rapid response (EDRR) actions—a coordinated set of actions to find and eradicate potential invasive species before they spread and cause harm.

The Port of San Diego, along with the Southern California Caulerpa Action Team (SCCAT), the City of Coronado, and the Coronado Cays Homeowners Association (CCHOA), are responding to the discovery of an invasive seaweed scientifically known as Caulerpa prolifera in the Coronado Cays area of San Diego Bay.

In late September, divers found a small patch of Caulerpa prolifera while conducting an in-water pre-construction eelgrass/Caulerpa dive survey as a permit condition for a dock replacement project. Additional patches were discovered nearby during follow-up surveys. The total find within the Cays is about one-quarter of an acre. The SCCAT has prepared a Rapid Response Eradication Plan to address the immediate need to eradicate this invasive species.

Today, Environment Minister Dustin Duncan introduced the Government of Saskatchewan’s new Aquatic Invasive Species Strategy during an address to the Saskatchewan Wildlife Federation’s (SWF) annual convention in Weyburn. The new framework is designed to help the province prevent, address and manage aquatic invasive species (AIS) threats. The ministry and the SWF are partners on the province’s AIS Task Force – which focuses on additional education and monitoring activities – along with other government agencies, conservation groups, non-government organizations and universities. "This strategy emphasizes the need for collaboration and co-ordination with provincial and federal government agencies, non-government organizations and neighbouring jurisdictions to prevent the introduction and spread of high-risk aquatic invasive species," Duncan said.

The rapid spread of buffelgrass through the Sonoran Desert rivals climate change and water scarcity as our region's most pressing environmental issue. Buffelgrass is one of many plants that were brought here from other parts of the world. Lacking the insects, diseases, and other organisms that helped keep them in check back home, some have spread like wildfire, much to the detriment of our native plants and animals. Buffelgrass is the worst of these invasive plants because it is not only invading our desert, but transforming our formerly fire-proof desert into a fire-prone grassland. The fight to control buffelgrass is the fight to save an ecosystem and some of the most magnificent stands of saguaros in the world. Volunteer for a buffelgrass pull, register your own buffelgrass pull, or request a presentation or ID guide.

ITP is pleased to announce that Sawfly GenUS is now complete. Developed in cooperation with the Washington State Department of Agriculture, Sawfly GenUS is an interactive identification tool for all sawfly genera found in the United States and Canada. This tool is intended to help recognize exotic sawfly introductions and provide access to general information on affected plants, range, and diversity of these insects. This tool should be useful for port identifiers and screeners, provincial and state departments of agriculture, university extension professionals, and any non-expert with an interest in sawflies.

For more than 30 years, the U.S. Fish and Wildlife Service has worked with Vermont and New York to control this invasive species and protect Lake Champlain. Fortunately, sea lamprey woundings are now at an all-time low.

The U.S. Geological Survey provides natural-resource managers with scientific information, risk assessment, and tools that can help to improve surveillance, prevention, and control strategies for managing invasive carp.

The plot could have come from Hollywood — an insidious alien invader threatens to overrun the land, but intrepid scientists discover a secret weapon in the far-off, exotic land of Nepal and bring the pestilence to heel. But this is not fiction; it's true. The air potato plant (Dioscorea bulbifera) is an exotic vine from Asia that was introduced to Florida about 115 years ago to make medicine. After escaping from the lab, it multiplied and smothered native plant communities in all of Florida's 67 counties. It spread beyond to large swaths of land in the southeastern United States. All attempts to manage the air potato – mechanical, chemical, or physically gathering the bulbils — were unsuccessful; they were either too labor intensive and costly or caused collateral damage to native and endangered species. According to Min Rayamajhi, a plant pathologist at the Agricultural Research Service's (ARS) Invasive Plant Research Laboratory (IPRL) in Fort Lauderdale, FL, the vines return every season, repeating the growth cycle and expanding the invasion at a rate of about 6 inches per day. Rayamajhi and retired ARS scientist Bob Pemberton traveled to Nepal and accidentally discovered the air potato beetle.

The SCIENCEx webinar series brings together scientists and land management experts from across U.S. Forest Service research stations and beyond to explore the latest science and best practices for addressing large natural resource challenges across the country. These webinars are primarily management-focused, but with applicability for participants from across sectors.

Biologists from the U.S. Geological Survey are racing the clock to pull four species of native Hawaiian Honeycreeper forest birds back from the brink of extinction. Factors such as habitat loss, invasive species, and non-native predators have been fueling the birds' decline for centuries. However, introduced diseases, particularly avian malaria spread through mosquitos, which are not native to the Hawaiian Islands, coupled with climate change, are the greatest threat facing Hawaiian forest birds today. 

"As the climate warms and more mosquitoes move into the once malaria-free regions of the mountains, healthy birds are running out of places to escape the cycle of infection," said Eben Paxton, a research ecologist with the USGS Pacific Island Ecosystems Research Center (PIERC) in Hawai'i. Now, PIERC biologists are working with a range of partners, including other Interior Department bureaus and the Birds Not Mosquitos Coalition, to intercept the disease cycle using a novel conservation tool.

Scientists have published a series of recommendations to enable communities and managers to minimise the impact of lionfish in the Mediterranean Sea. The invasive species was first noticed off the coast of the Lebanon in 2012, with sightings since recorded as far west as Sicily, and north into the Adriatic Sea off Croatia. More entered in 2015 due to the enlargement and deepening of the Suez Canal, with their spread unimpeded due to a lack of common predators. Researchers in the UK and Cyprus have said increasing lionfish densities – combined with the species' generalist diet and consumption of ecologically and socio-economically important fish – has the potential to result in further disruption of an already stressed marine environment. They have now published a Guide to Lionfish Management in the Mediterranean [PDF, 8.0 MB], which features a series of recommendations through which they hope lionfish populations can be managed.
