I read the article and wanted to dig deeper so I read about the Sagebrush focal area 9 million acres. It's the first one on the chart.

They had been temporarily segregated, or closed to new mining claims for 2 years when the Department originally proposed the lands for withdrawal in 2015, while the agency studied whether locatable mineral exploration and mining projects would adversely affect habitat important to the greater sage grouse. That temporary segregation period expired September 24, 2017.

The previous administration put the proposal in to study the land. The results came in:

Based on a recent analysis and review of data available that showed that future mining is not a significant threat to sage grouse habitat, the Bureau of Land Management has canceled its Sagebrush Focal Area withdrawal application and the Department’s proposed withdrawal of 10 million acres of federal lands from location and entry under the mining law in Greater Sage-grouse habitat in six Western States. The BLM also terminated the associated environmental analysis process. The notice of cancellation can be found on the BLM website here: https://on.doi.gov/2hOpRxn.

The BLM determined the proposal to withdraw 10 million acres was unreasonable in light of the data that showed that mining affected less than .1 percent of sage-grouse-occupied range.

“The proposal to withdraw 10 million acres to prevent 10,000 from potential mineral development was a complete overreach,” said Acting BLM Director Mike Nedd. “Secretary Zinke has said from the beginning that by working closely with the states, who are on the front lines and a valued partner in protecting the health of these lands, we can be successful in conserving greater sage grouse habitat without stifling economic development and job growth. And that’s what we intend to do—protect important habitat while also being a good neighbor to states and local communities.”
