Central Oregon serves as a hotspot for both spotted bats (Euderma maculatum) and outdoor recreation. With this project, we seek to take advantage of the unique intersection of bat habitat and recreation opportunities. Spotted bats are one of the few bats that use echolocation frequencies low enough to be heard and identified by humans. They lead secretive lives, but we know they like to roost high in rock crevices among cliff faces like the ones here in Central Oregon. To gain a better understanding of where this species spends its summers, we are asking for the public’s help in listening for these unique animals. After attending a training session, volunteers will get to choose from a long list of listening locations, and then choose what evening they want to survey. This project is designed to be flexible enough for anyone to participate.
