White-nose syndrome has been spreading through U.S. bat populations since 2006 and has caused mass die-offs in various regions of the country. The syndrome is caused by Pd (Pseudogymnoascus destructans), a fungus that invades the skin of bats while they hibernate. USDA Forest Service wildlife biologists Roger Perry and Phillip Jordan conducted a study to calculate the survival rates of tricolored bats (Perimyotis subflavus) in the Ouachita Mountains of west-central Arkansas. The research helps satisfy the need for robust estimates of population data amid the WNS outbreak. The scientists chose to study the tricolored bat because it is common across North America and has suffered substantial declines due to WNS. The research highlights the importance of maintaining and protecting small hibernation sites as they may be critical to the conservation of the tricolored bat species.

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.

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.

The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) is working with the Texas Department of Agriculture (TDA) to combat the Mexican fruit fly (Anastrepha ludens) in Cameron and Willacy Counties in Texas. Following the detection of this pest in Cameron and Willacy Counties in January 2020, APHIS put quarantines in place to contain this fruit fly and is conducting surveys to find and treat infestations. Mexican fruit fly is one of the world's most destructive invasive pests, attacking more than 40 different kinds of fruits and vegetables. This invasive fruit fly does not harm humans or animals but it poses a serious threat to the Texas citrus industry.

APHIS needs the public's help to limit this invasive fruit fly's spread. We are asking residents living or working within Mexican fruit fly quarantine areas to cooperate with survey teams and give them access to your property. Surveyors will have official credentials identifying them as U.S. Department of Agriculture or TDA employees. With the residents' permission, they will inspect fruit trees on residential properties in quarantine zones and hang traps. If APHIS or TDA detect Mexican fruit flies, they will work with residents and business owners to eradicate the pest from infested properties.

If you live in the Lower Rio Grande Valley and think you might have Mexican fruit flies on your property, please call APHIS at 956-421-4041. With your help, we can protect local agriculture and stop the spread of this destructive pest.

Motorized and trailered watercraft launching in Blue Mesa Reservoir are required to be inspected for aquatic invasive species prior to launching, and if necessary, decontaminated in accordance with procedures set by the Colorado Division of Wildlife. In addition to the mandatory inspection prior to launch, boaters are encouraged to get an exit inspection to verify the watercraft has been cleaned, drained and dried.

Bats are dying. Please help us protect them. A disease called white-nose syndrome (WNS) is spreading through the eastern United States, killing bat populations. White-nose syndrome is considered to be present in the Mammoth Cave System. It is believed that humans may contribute to the spread of white-nose syndrome by visiting contaminated caves or mines and then wearing the same clothing or carrying the same objects to unaffected caves or mines, transporting spores from one place to the other. You can help us save bats by following a few simple guidelines.
