South Dakota holds the strongest long-legged myotis record in the northern plains: 148 reports since 2000, with a spread that covers both ends of the state’s forested country. Harding County’s Cave Hills and Slim Buttes lead the county list, the Black Hills counties of Custer, Pennington, and Lawrence follow close behind, and Jackson County adds a surprising bloc from the Badlands in between.
The named places reinforce that shape. Badlands National Park tops the list, with Jewel Cave National Monument and Wind Cave National Park close behind. Dry badlands and cave country might not look like classic habitat for a forest bat, but the long-legged myotis roots its days in rock crevices and cliff faces as readily as in trees, and it hunts over whatever the night offers. NatureServe ranks it apparently secure in the state, one of its better standings anywhere.
June and July tower over every other month in the record. That’s the bats’ peak activity season overlapping with the field season for the survey crews, and it’s the honest way to read the calendar here: records show when bats and biologists meet, not the whole of what the bats are doing.
