Notable bat roosts
In 2009 the Grandview Mine in the Grand Canyon National Park had gates added to support on-going bat research, preserve historic mine resources, and promote visitor safety.

The Ann W. Richards Congress Avenue Bridge, which crosses over Lady Bird Lake in Austin, Texas, is the world's largest urban bat colony.

Seventeen species of bats live in the Carlsbad Caverns National Park, including a large number of Mexican free-tailed bats. It has been estimated that the population of Mexican free-tailed bats once numbered in the millions but has declined drastically in modern times. The cause of this decline is unknown but the pesticide DDT is often listed as a primary cause.

State insignia
As of February 2011, at least three states had an official bat. Hawai'i named the Hawaiian hoary bat as the official state land mammal in April 2015. The general assembly of North Carolina considered a bill in 2007 that would have made Rafinesque's big-eared bat as its state bat. The bill passed 92-15, but died in the state senate. In 2020, the big brown bat was designated the official state mammal of the District of Columbia. In 2023, a successful campaign was launched to make the pallid bat the state bat of California. The bill passed both houses unanimously and will take effect on January 1, 2024.
