Overview

The Department of the Interior's FY2027 budget request is $15.9 billion, about 12.9% less than the $18.2 billion enacted in FY2026. The largest reductions include a $500 million cut to programs the administration calls duplicative, which fund international wildlife conservation, wildlife grants, and loans to Native American borrowers, plus a full elimination of $300 million for USGS ecosystem science that tracks invasive species, bird flu, and contamination. Water users in Western states, especially farmers relying on irrigation during droughts, would feel a $200 million cut to the Bureau of Reclamation, while offshore wind and renewable energy developers on federal lands would lose all $45 million in dedicated program funding. Overall, the cuts affect farmers, tribal communities, scientists, and clean energy developers who depend on Interior Department programs.
