Eastern Montana includes some of the world’s largest remaining stretches of intact native grasslands. Where they exist, such prairies are rich in wildlife, but less than 5% of temperate grasslands are considered protected, making them among the most endangered ecosystems in the world. In 2017, nature sound recordist Kevin Colver and I began documenting the sounds of Montana's shortgrass prairies through a collaboration with the American Prairie Reserve. You can find many of these recordings in a new collection on the Acoustic Atlas.
