Even before the widespread incidence and threats of White-nose syndrome (WNS) were known, human disturbance to bats while they hibernate has been a well-documented threat in the Northeast. Many of the pre-WNS conservation efforts focused on better protection of critical winter habitat for bats, which can include caves, abandoned mines, sinkholes, aqueducts and other locations natural or man-made where bats overwinter. Management actions can improve the structures for bats while preventing human disturbance.
