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.

Key partners and contributors in Napa County, California, recently celebrated and recognized the critical safeguarding accomplishment achieved together, of eradicating the invasive European grapevine moth (EGVM) from the U.S. The keys to success were early detection, our rapid response, and a strong collaboration between federal, state and local officials, growers, university scientists and extension services. Such partnerships remain critical to our ability to safeguard agriculture and facilitate safe trade.

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.
