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.

U.S. Customs and Border Protection (CBP) agriculture specialists have already intercepted a dozen significant and potentially destructive pests this year at various ports of entry in Florida as part of the agency's all-encompassing efforts to safeguard American agriculture.
Unknown pests pose a significant risk in agriculture due to a lack of knowledge in controlling the pests and the extent of damage they can cause to crops. U.S. Department of Agriculture (USDA) entomologists recently classified eight pests discovered by CBP agriculture specialists in Florida as first-in-the-nation interceptions and another pest as a new species.

U.S. Department of the Interior Assistant Secretary, Insular and International Affairs, Douglas W. Domenech announced the release of $3,442,389 in fiscal year (FY) 2020 grant funding to suppress and control the brown tree snake (BTS), Boiga irregularis, primarily on Guam. Funds also support prevention, detection, and rapid response efforts in the Commonwealth of the Northern Mariana Islands (CNMI) and Hawaii, in addition to research and development on how to improve suppression methods and potentially eradicate the snake on Guam. The Office of Insular Affairs (OIA) Brown Tree Snake Control program FY 2020 funds are divided among several federal, state, and territorial agencies that collaborate in support of the three pillars of BTS suppression: $1,229,296 is used for control in rapid response and research activities, $1,724,210 is used for interdiction, and $488,883 is used for prevention through coordination and outreach.

U.S. Department of the Interior Assistant Secretary, Insular and International Affairs, Douglas W. Domenech announced $942,206 in fiscal year (FY) 2020 Coral Reef and Natural Resources Initiative grants to eradicate and control the spread of invasive species in the U.S. territories of Guam and the Commonwealth of the Northern Mariana Islands (CNMI), as well as in the Republic of Palau, and Yap, in the Federated States of Micronesia (FSM). Funding will be used to introduce biological control of coconut rhinoceros beetles, control and eradicate feral cats and monitor lizards, and destroy wild vines, all of which are disruptive to ecological systems and impacting communities and livelihoods in the islands.
Early in October 2016, the U.S. Department of Agriculture (USDA) was faced once again with New World screwworm, which had been eradicated from the United States more than three decades ago. Infestation of this flesh-eating parasite was confirmed in deer from the National Key Deer Refuge in the Florida Keys.
USDA’s Animal and Plant Health Inspection Service (APHIS) immediately began releasing sterile male flies in Florida’s affected areas as part of an aggressive eradication campaign. By March 2017, the screwworm had been successfully eradicated from Florida.

On May 14, Director Reilly signed a Memorandum of Agreement with the Department of the Navy and the U.S. Fish and Wildlife Service. The MOA provides for continuity of operations for the USFWS and the USGS with construction of new office and lab facilities on the Guam National Wildlife Refuge in conjunction with DOD’s construction of a Marine Corps firing range. "The USGS has a long history of collaborating with the Department of Defense in support of U.S. facilities and force readiness in the INDOPACOM Area of Responsibility. One of our signature efforts ongoing today is a collaboration with DOD, the U.S. Fish and Wildlife Service, and the local government in minimizing the impacts of the invasive Brown Treesnakes (BTS) and improving BTS controls on military lands on Guam," said Jim Reilly, director of the USGS.
