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.

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.
