  • What Makes This Invasive, Non-Native Reed Grass Thrive in the Wetlands?

    • Apr 6, 2022
    • Louisiana State University.

    • The Mississippi River Delta is home to the world’s largest contiguous swath of Phragmites australis, or more commonly known as the common reed. But the plant that can grow to nearly 20 ft. and has been a critical component in stabilizing the state’s coastal erosion is not actually native to Louisiana—well, not entirely. There are multiple P. australis genotypes. P. australis subspecies (ssp.) americanus is the native subspecies in the U.S. and Canada. However, Phragmites australis ssp. australis originated in central Europe and was subsequently introduced to the U.S. where it is now considered to be one of the most problematic invasive species in North America. "Novel genome characteristics contribute to the invasiveness of Phragmites australis (common reed)" in Molecular Ecology and recently featured in an edition of The Scientist, LSU researchers collaborated with Tulane University and the U.S. Geological Survey to study the genomic bases of P. australis and to investigate what exactly makes the invasive reed grass subspecies thrive in wetlands, in comparison to its native counterpart.

  • What’s Killing Beech Trees?

    • Feb 3, 2020
    • USDA. ARS. Tellus.

    • 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.

  • Where Are They Now? Monitoring Firewood-Vectored Invasive Forest Pests in North Carolina [PDF, 875 KB]

    • North Carolina Department of Agriculture and Consumer Services. North Carolina Forest Service.

    • 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.

Events typically involve five or more sick or dead wild animals observed in the same general location and time period. This information is collected opportunistically and provided here by multiple State, Federal, and other agencies to enhance collective understanding of disease in wildlife populations.

  • White-Nose Syndrome in Bats

    • Idaho Department of Fish and Game.

    • White-nose syndrome (WNS) is a disease that is identified by the telltale white fungus growing on the noses of some infected bats while they hibernate. The Idaho Department of Fish and Game is asking the public to report the sighting of any active or dead bats during winter. Please call 208-454-7638 to report sightings. Idaho Fish and Game would also like to know of any sites that have hibernating bats so biologists can include them in the monitoring effort. Finally, the public is asked to not disturb hibernating bats and to respect cave closures.

  • White-Nose Syndrome Killed Over 90% of Three North American Bat Species

    • Apr 21, 2021
    • DOI. United States Geological Survey.

    • White-nose syndrome has killed over 90% of northern long-eared, little brown and tri-colored bat populations in fewer than 10 years, according to a new study published in Conservation Biology. Researchers also noted declines in Indiana bat and big brown bat populations. The findings, detailed in "The scope and severity of white-nose syndrome on hibernating bats in North America," underscore the devastating impacts of the deadly fungal disease. The research tapped into the most comprehensive data set on North American bat populations to date, which includes data from over 200 locations in 27 states and two Canadian provinces.

  • Wild Spotter - Mapping Invasives in America's Wild Places

    • University of Georgia. Center for Invasive Species and Ecosystem Health; Wildlife Forever; USDA. Forest Service.

    • Wild Spotter is a nationwide effort to complete a comprehensive map and survey of prioritized invasive through on-the-ground activities accomplished by citizen science volunteers. Wild Spotter is a tool that allows the general public to report invasive species in their favorite places. Unlike, EDDMapS it is focused locally and focused on the non-traditional invasive species audiences. Widespread adoption and use of Wild Spotter is key to protecting our public lands.  Wild Spotter is part of EDDMapS, data is part of the EDDMapS database, and it uses the existing EDDMapS review and verification system. 

      You can help fight back against invasive species in America's wild places by downloading the free Wild Spotter Mobile App on your smartphone or other mobile devices. You'll learn how to identify, map, and prevent the spread of these invaders in order to protect our rivers, mountains, forests, and all wild places for future generations. Learn more by watching the Wild Spotter Introduction Video. To become a volunteer, register either online or download the Wild Spotter Mobile App. Once registered, reach out to your nearest National Forest or Grassland to discover how you can volunteer to help support and protect these beautiful places from invasive species. Then, just get outside and enjoy America's wild places while keeping an eye out for those harmful invaders!
