The Wildfire Research Coordination Act of 2026 aims to enhance coordination between the Department of Defense, Agriculture, and Interior for joint fire science research priorities. It requires a memorandum of understanding within 180 days to identify research priorities aligning with existing programs, and to direct coordination between them. Additionally, the Secretary of Defense must submit a report on the implementation progress within one year to the House and Senate Armed Services Committees. This bill will impact the coordination and prioritization of research and technology relating to fire science, including mitigation, ecological resilience, fire and smoke modeling, response, and post-fire recovery.
