Fire-adapted invasive plants alter wildfire regimes — some by increasing fire frequency and intensity, others by suppressing it. Both dynamics degrade native ecosystems and demand science-based management. This publication examines the ecology, policy landscape, and integrated management options for invasive plants that change wildfire regimes, with case studies from California, the Southeastern United States, and the Sagebrush Steppe. Effective management requires coordinated action, adaptive strategies, and restoration practices tailored to local conditions and land management goals.
