  • 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.

    • White-nose Syndrome is a mysterious disease that is killing bats across the northeast United States. Many research projects are underway to help in the fight against WNS, from researching fungicides to modeling the spread and effects of the syndrome. If you would like to help, there are many ways in which you can:

      • Report any unusual bat activity (bats flying in the daytime) or unexplained bat deaths to your regional TWRA office. Or check out the Report a Bat Link on this website.
      • Donate to a number of funds collecting money for WNS research (see National Speleological Society and Bat Conservation International pages below).
      • Adhere to state and federal cave closure advisories.
      • Encourage state and federal agencies to assist in WNS research and monitoring activities.

    • 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!
