JUNEAU, Alaska — The Biden administration said Friday it will restrict new oil and gas leasing on 13 million acres (5.3 million hectares) of a federal petroleum reserve in Alaska to help protect wildlife such as caribou and polar bears as the Arctic continues to warm.

The decision — part of a yearslong fight over whether and how to develop the vast oil resources in the state — finalizes protections first proposed last year as the Democratic administration prepared to approve the contentious Willow oil project.
