If you plan to use your own boat or angler float tube, you’ll need a permit and a free Yellowstone aquatic invasive species inspection. You can speed up the inspection process by arriving with a boat that is clean, drained, and dry. Watercraft that arrive dirty or with standing water will be subject to decontamination. Watercraft that cannot be properly decontaminated will be prohibited from launching.

On Tuesday, June 5, 2018, the United States Department of Agriculture (USDA) National Veterinary Services Laboratory (NVSL) confirmed the presence of the Longhorned tick (Haemaphysalis longicornis) in Arkansas. The Longhorned tick is an exotic East Asian tick associated with bacterial and viral tickborne diseases of animals and humans in other parts of the world. This tick is considered by USDA to be a serious threat to livestock because heavy tick infestations may cause stunted growth, decreased production and animal deaths. Like deer-ticks, the nymphs of the Longhorned tick are very small (resembling tiny spiders) and can easily go unnoticed on animals and people. This tick is known to infest a wide range of species and has the potential to infect multiple North American wildlife species, humans, dogs, cats, and livestock.

Firefighting personnel can unintentionally transport invasive species on clothes, gear, and equipment from the lower 48 to Alaska. They can also unintentionally spread invasive species within Alaska, from infested areas to clean areas. Aquatic invasive species can also be spread any time water is moved from an infested area to another waterbody, when seeds, propagules, or larvae are carried in small amounts of water or trapped in the water-handling equipment. This booklet is a tool to help identify some of the invasive species of greatest concern in Alaska and also suggests BMPs that will help firefighting personnel avoid introducing or spreading them. It also identifies four invasive species that should be reported to authorities and how to report them. See also: Invasive Plants Publications for more resources.

Are you a crabber, waterman, or concerned citizen? We need your help to detect and assess the status of Chinese Mitten Crabs. The "Mitten Crab Watch" website provides information on the invasion of the mitten crab and allows users to more easily report catches.

Please help us detect live mitten crabs by reporting any sighting in North America. We are especially interested in collecting sightings from the Chesapeake Bay, Delaware Bay, Hudson River, and San Francisco Bay --- where the crab has been common in the past. Please visit the Mitten Crab Watch website to learn more about the crab and to report sightings.

Partnering with a local Alaskan native community, the U.S. Forest Service has for the first time published a dual language booklet in English and a native Alaskan language, Yup'ik, to help educate the greater community in Southwestern Alaska on invasive species. This publication, Protecting Southwestern Alaska from Invasive Species: A Guide in the English and Yup'ik Languages, aims to explain invasive species concerns unique to Southwestern Alaska, which is home to a large community of the indigenous Yup'ik people.

Maryland’s eastern shore has seen thousands of acres of protective marshland impacted by the nutria's destructive feeding habits. To protect the valuable resources of Maryland’s Chesapeake Bay, The Chesapeake Bay Nutria Eradication Project (CBNEP) began in 2002 to permanently remove invasive nutria from the marshes of the Delmarva Peninsula and to protect, enhance, and restore the aquatic and river ecosystems they damaged.
