This page contains links to letters sent between the Wyoming Game and Fish Department and the U.S. Fish and Wild Service regarding whether wind power development is permitted in Wyoming's 'core sage grouse habitat area'. Brian Kelly of the USFWS states in his letter that “ . . . constructing wind farms in core areas, even for research purposes, prior to demonstrating it can be done with no impact to sage grouse, negates the usefulness of the core area concept as a conservation strategy and brings into question whether adequate regulatory mechanisms are in place to protect the species.”
