The Trump administration is proposing a drastic reimagining of how public lands across the United States are used and managed, according to an Interior Department document leaked to the public in late April. The document, a draft of the department’s strategic plan for the next five years, downplays conservation in favor of an approach that seeks to maximize economic returns, namely through the extraction of oil, gas and other natural resources.

“That’s a blueprint for industrializing the public lands,” said Taylor McKinnon, who works on preservation of Southwestern lands for the Center for Biological Diversity, a nonprofit organization. “A separate question is whether they’re able to achieve that,” Mr. McKinnon said, vowing lawsuits from his group and others.

Sweeping proposals are a species native to Washington, D.C., and many of them stand little chance of being realized. However, Donald J. Trump has begun his second term as president at a blistering pace, remaking or shuttering entire federal agencies with such speed that opponents have only recently found their footing.

“I would take it every bit as seriously as I would take what is laid out in Project 2025,” said Jacob Malcom, who until recently headed the Interior Department’s office of policy analysis. Project 2025, a 900-page document issued in 2023 by the Heritage Foundation, has served as a blueprint for the Trump administration on a host of policy fronts — including in its approach to public lands. The section of Project 2025 dealing with the Interior Department was primarily written by William Perry Pendley, a conservative activist.

Of the several goals laid out in the draft strategic plan — which was pointedly made public on April 22, when Earth Day is marked — “Restore American Prosperity” earns top billing. To achieve that aim, the Interior Department proposes to “open Alaska and other federal lands for mineral extraction,” “increase revenue from grazing, timber, critical minerals, gravel and other nonenergy sources” and “increase clean coal, oil and gas production through faster and easier permitting.”
