Bats are economically and ecologically important animals, providing ecosystem services such as pollination and predation of insects. Most bat species are difficult to study in the wild because of their nocturnal foraging and cryptic, inaccessible roost sites. In general, bat populations are believed to be declining.The wildland-urban interface, or the intersection between wild and urban areas, is an important location for inventorying and monitoring of bat populations to determine the impacts of human development. Bats make ultrasonic vocalizations to communicate and echolocate prey. Researchers can record and analyze these calls using acoustic sampling methods. Acoustic sampling was conducted at Eugene O'Neill National Historic Site, John Muir National Historic Site, and Point Reyes National Seashore. All of these parks are on the wildland-urban interface.
