Learn About Bats

Bats are beneficial to humans and ecosystems.

When we protect bats, we are protecting the health of our communities, our ecosystems, and our crops. Bats eat insects and control pests that harm crops, damage forests, and transmit diseases. Bat conservation is also vital for agriculture because bats pollinate or disperse seeds of more than 1,000 species of plants globally, including many that we rely on for food such as bananas, mangos, and cocoa.

Meet Our Bats

Colorado is home to 19 bat species. Bats can be found in any part of Colorado, from eastern prairies to mountain forests to western canyons, and from small towns to downtown Denver. Unfortunately, relatively little is currently known about the population status of most species of bats in Colorado. That’s where you come in! Get involved and help us generate knowledge about bats.

Bats in the U.S. face many threats and need our help.

Bats face numerous threats in Colorado, including habitat loss, energy development, and pesticides. In addition, hibernating bats in Colorado may be impacted by white-nose syndrome (WNS), a pathogen that has killed millions of bats in the eastern and midwestern U.S. since 2006. The fungus that causes WNS was detected in Colorado for the first time in July of 2022.
