President Joe Biden s administration on Friday safeguarded millions of acres in Alaska from fossil fuel drilling and mining the latest in a frenzy of environmental actions in recent weeks that have drawn praise from green groups and condemnation from industry and Republican lawmakers.

The Interior Department finalized a rule that bars oil and gas development across more than 13 million acres of the National Petroleum Reserve on Alaskas North Slope. Established in 1923, the 23 million-acre reserve is the largest tract of federal land in the country and home to vast oil and gas deposits.

Interior also moved to block construction of the Ambler Road, a proposed 211-mile mining road that would have cut through a portion of Alaskas pristine Gates of the Arctic National Park and Preserve to access billions of dollars worth of copper deposits.

Both actions ultimately reverse decisions from Donald Trump s presidency.

Todays announcements underscore our commitment to ensure that places too special to develop remain intact for the communities and species that rely on them, Interior Secretary Deb Haaland said in a statement. There is no question, using the best available science and incorporating Indigenous knowledge practiced over millennia, that these decisions will help biological, cultural, historic and subsistence resources, safeguarding the way of life for the Indigenous people who have called this special place home since time immemorial.
