Gov. Matt Mead’s Sage Grouse Implementation Team tomorrow will consider whether to recommend extending core-area protection across a proposed gas field.
Wyoming will let the BLM, not the state, govern development of a gas field that’s home to 2,000 wintering grouse, a state adviser said last week.
A statewide team will soon decide whether to protect greater sage grouse habitat in Sublette County or develop a 3,500-well natural gas field in the heart of the bird’s wintering grounds.
