PROTECTION STATUS: Federally listed as threatened in 2015; state-listed as endangered in Vermont and Massachusetts and as threatened in Wisconsin


RANGE: Patchily distributed in all Canadian provinces; in the Yukon and Northwest Territories; and in eastern, midwestern and some southern states, with a small number of sightings reported in Montana and Wyoming

THREATS: White-nose syndrome; habitat destruction, including from logging, residential and agricultural development, mineral extraction and sealing of entrances to abandoned mines; environmental contaminants; industrial wind-energy projects; climate change

POPULATION TREND: This species has declined by approximately 99 percent in the eastern portion of its range due to white-nose syndrome, and is projected by scientists to continue to decline at similar rates throughout its entire range as the disease spreads westward.
