Only a couple of dozen bats spent this past winter in New Hampshire.
That’s down from thousands a decade ago, before a fungus called white nose syndrome decimated many species’ populations in 2009.
Biologist Scott Reynolds says since then, the mine shafts where bats used to hibernate in large numbers have been pretty empty.
But white nose has also subsided in New Hampshire.
Now, Reynolds says recovery for the species hit hardest, such as little brown bats, is just beginning.
