White Nose Syndrome in Northern Minnesota

Biological data collection tent under the night sky

Project Overview:

White nose syndrome is a deadly affliction for many species of North American bats. It is caused by a white fungus that affects hibernating bats; often manifesting itself on the the muzzles and wings of individuals. First discovered to be causing mortality in 2006-2007, the disease has spread across the country and has devastated populations. There is a joint effort between federal, state, and non-profit agencies to learn more about white nose syndrome and how to suppress the affliction (Amelon et al., 2012). Biologists and technicians set up nets to catch wild bats and monitor the spread of the disease. During the summer months, the wing membranes of affected bats can show evidence of white nose. De-pigmentation, small holes in the membrane, necrotic tissue, and flaking skin on the forearms are evidentiary. All bats are weighed, sexed, inspected, and outfitted with an aluminum identification band and released (USFS, 2020). 

What can YOU do to help the effort?

-- Consider building a bat box (home for bats) on your property by following these bat box building instructions

-- If you find a natural bat "hibernacula" (where bats overwinter) or have a sighting of a bat that you suspect may have white nose syndrome, please report it to the USFS. 

-- Keep yourself informed and follow along by visiting this USFS web-page
