A new study shows that vaccination may reduce the impact of white-nose syndrome in bats, marking a milestone in the international fight against one of the most destructive wildlife diseases in modern times. "This is a significant step forward in developing control mechanisms to combat the devastating spread of white-nose syndrome in our important bat populations," said USGS Director Jim Reilly. "Being able to deliver an oral vaccine during hibernation could be a game changer in our ability to combat one of the deadliest wildlife diseases in modern times." White-nose syndrome is caused by a fungus called Pseudogymnoascus destructans, or Pd, and has killed millions of North American bats since 2006. The disease is spreading rapidly and there is no cure.

The U.S. Department of Health and Human Services released the National Public Health Strategy to Prevent and Control Vector-Borne Diseases in People (VBD National Strategy). As directed by the 2019 Kay Hagan Tick Act—named after the U.S. Senator who died due to complications from a tickborne illness—HHS led a four-year process with civilian agencies and defense departments to deliver this strategy. Co-led by the HHS Office of the Assistant Secretary for Health and the Centers for Disease Control and Prevention, the strategy identifies and describes federal priorities to detect, prevent, respond to, and control diseases and conditions caused by vectors in the United States. This VBD National Strategy represents the largest formal federal coordination effort focused on vector-borne disease prevention and control with contributions by over 50 representatives across 17 federal agencies.

Thousand cankers disease (TCD) is a disease complex native to the western United States and primarily affects black walnut, Juglans nigra. This disease is the result of the combined activity of a fungus, Geosmithia morbida, and the walnut twig beetle WTB), Pityophthorus juglandis. On January 12, 2015, the the Maryland Secretary of Agriculture issued a quarantine order to minimize the risk of moving infested material out of the limited action area in Cecil County, and to provide confidence in Maryland walnut products moving into neighboring states from non quarantined areas. The 2015 quarantine order has been updated to include all of Baltimore City and part of Baltimore County [PDF, 1.2 MB]. The new quarantine [PDF, 1.0 MB] was signed on May 1, 2019 by the Maryland Secretary of Agriculture.

A chance discovery in an Ohio woodland has turned into a multi-disciplinary, multi-agency, and multi-national effort to piece together a puzzle and understand a scourge that is killing trees by the thousands in northern states east of the Great Plains. The leaves of young beech trees are failing somehow. Scientists have figured out what causes the malady; it’s the 'how' that has them scratching their heads. Beech trees are one of the most common trees in America's northern and northeastern forests. Their nut crop feeds birds and other animals, and its wood is prized for bentwood furniture. The symptoms of beech leaf disease were plain to see – sunken dark spots on the leaves, which eventually died – but opinions differed on the cause. Was it bacterial, fungal, or viral? Then, a plant pathologist working for the State of Ohio noticed wiggly things in the leaf lesions. They turned out to be nematodes, microscopic worms that live in the soil, that had somehow managed to make it to the tree canopy 40-50 feet above ground. Nematode samples were sent to Beltsville, MD, for analysis and identification at the Agricultural Research Service (ARS) Mycology and Nematology Genetic Diversity and Biology Laboratory in Beltsville, MD. The nematode, Litylenchus crenatae, turned out to be native to Japan – the first population of L. crenatae found in the Western Hemisphere. The curious thing is that it's not a tree-killer in Japan.

Emerald ash borer, laurel wilt disease, thousand cankers disease, and the European gypsy moth are likely to be brought into North Carolina in or on firewood. The use of local firewood is an important factor in preventing the spread of potentially devastating invasive species to our state's forests. Please keep this in mind as you prepare for your outdoor recreation activities. See Forest Health Invasive Pest Maps for more information about pest monitoring.
