As we’ve just heard, there’s a lot of concern over declining sage grouse numbers. And a lot of effort is going into keeping the birds from being included on the endangered species list. Part of that effort involves studying which aspects of human activity are most problematic. A new study published in the journal Conservation Biology examines how human-made noise – particularly the noise associated with gas development – affects sage grouse. We’re joined now by Jessica Blickley, one of the authors of the report. She says her study is part of an ongoing effort to understand exactly what it is about energy development most affects the birds.
