Oil and gas leases proposed on about 4,200 acres of public land in Colorado have been yanked from a sale planned for December because of a court ruling on federal conservation plans for greater sage grouse. The Colorado Bureau of Land Management said on its website Wednesday that the six parcels up for lease in Jackson, Moffat and Rio Blanco counties “will be reconsidered for a future sale” because of a preliminary injunction issued Oct.16 by U.S District Judge Lynn Winmill in Boise, Idaho. The ruling temporarily suspends the Trump administration’s changes to plans the Obama administration approved in 2015 to protect greater sage grouse, whose numbers have been dropping for decades across the West, including in Colorado.
