Intense summer heat waves and severe winter storms have taken a toll on bat populations. Learn more about climate change - primarily extreme temperatures and prolonged drought. Though there have been previous periods of climatic change, since the mid-20th century humans have had an unprecedented impact on Earth's climate system and caused change on a global scale. Bats that live in caves can be especially vulnerable to disturbance from climbing and caving enthusiasts.īats are also impacted by the effects of climate change climate changeĬlimate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. But across North America, bats are threatened by degradation and destruction of their roosts and foraging areas. Some species live in trees, others in caves or mines, and some in rock crevices. Healthy bats need healthy and safe habitats, and different bat species choose different kinds of homes. Image Details Tricolored bat with visible symptoms of white-nose syndrome. The White-nose Syndrome Response Team, comprised of non-governmental, state, local, federal and Tribal partners, has focused research efforts to develop treatments, vaccines and prevention measures to lower the risk of extinction for susceptible native bat species. Twelve North American bat species are known to be susceptible to white-nose syndrome when they hibernate during winter. The fungus has spread across the United States and Canada, killing nine out of 10 little brown, northern long-eared and tricolored bats. Millions of bats have perished from white-nose syndrome, a deadly fungal disease of hibernating bats first discovered in New York in 2007. ![]() ![]() Other endangered bat species include the Florida bonneted bat, Ozark big-eared bat, lesser long-nosed bat and Virginia big-eared bat. Currently, three bat species impacted by white-nose syndrome - the gray bat, Indiana bat and northern long-eared bat - are listed as endangered under the Endangered Species Act, and one - the tricolored bat - is proposed as endangered. Legal protection, local action, research attention, public support and cross-boundary collaboration all contribute to safeguarding our bats. Knowing the state of North America’s bats informs how we prioritize and design conservation actions. Conservation relies on identifying threats and determining the status of each bat species. The bat experts agree - the next 15 years are critical for ensuring a better future.
