According to this article efforts to save the little brown bat in NJ is pretty much a lost cause. They’ve lost 95% of their population since 2009 to the white-nose syndrome. I remember visiting the Bat Hibernaculum in Morris County about 7-8 years ago and it was amazing watching them swarm in (or out)… now you wouldn’t see that, they’re just not there.
