Abstract:The authors conducted a two-year study to assess the distribution, roosting and foraging ecology, migratory movements, and winter habits of gray bats (Myotis grisescens) in the French Broad River Basin of western North Carolina. By August 2020, the authors knew of 37 roosts in the basin. Gray bats actively forage across the basin, but activity is highest north and west of Asheville. Gray bats are active in the basin from March to November each year. The authors recommend maintaining a current list of bridges, culverts, and buildings used by gray bat roosts in this region to inform project planning and maintenance. Both culverts and bridges are suitable structures for use during at least part of the year. Gray bats are present along streams in the French Broad River Basin and other parts of western NC; more distribution surveys are needed.
