Greater sage-grouse response to bentonite mining

2020-6-16  contrast, disturbance from bentonite mining has a smaller footprint than surface coal mining, but is more expansive. However, the duration of active mining disturbance from coal mining is likely decades longer than from bentonite mining. Even though oil and gas development may be a significant disturbance factor across the eastern sage-grouse
