endangered and threatened bat species
North American bats face many challenges. White-nose Syndrome (WNS) has killed at least 6 million hibernating bats since its arrival in New York in 2006. Wind energy continues to develop as an alternative energy source. Researchers estimate that as many as 1.7 million bats were killed in the US and Canada prior to 2011. Additionally, as many as 1.3 million fatalities may have occurred in 2012 alone, and that migratory species are impacted most heavily. Climate change is altering weather patterns and landscapes, reducing the availability of water resources for bats, especially in the arid Southwest. Habitat alteration and fragmentation can threaten roosting and foraging sites for some species. And human disturbance continues to be a problem for bats at unprotected caves and mines.
In the US, 8 species or subspecies of bats are listed as Endangered (see below) and a single species, the northern-long eared bat (*) is listed as Threatened.
- Florida bonneted bat (Eumops floridanus)
- Gray bat (Myotis grisescens)
- Hawaiian hoary bat (Lasiurus cinereus semotus)
- Indiana bat (Myotis sodalis)
- Lesser long-nosed bat (Leptonycteris yerbabuenae)
- Mexican long-nosed bat (Leptonycteris nivalis)
- Ozark big-eared bat (Corynorhinus townsendii ingens)
- Virginia big-eared bat (Corynorhinus townsendii virginianus)
- Northern long-eared bat (Myotis septentrionalis)*
In Canada, 3 species of bats are listed as Endangered under the Canadian Species At Risk Act (see below) and one species, the pallid bat (*) is listed as Threatened.
- Little brown bat (Myotis lucifugus)
- Northern long-eared bat (Myotis septentrionalis)
- Tri-colored bat (Perimyotis subflavus)
- Pallid bat (Antrozous pallidus)
Bats, as the primary predators of night-flying insects, play a crucial ecological role. But they have a vital economic role, too. Research has shown that bats provide between a $3.7 and $52 billion ecosystem service benefit to US farmers and ranchers, by reducing the costs of pesticides. If we continue to lose bats from WNS, wind facility fatalities, and other causes, there will be an economic impact.
