This legislation, known as the "Fix Our Forests Act," seeks to accelerate and improve forest management activities on National Forest System lands, public lands, and Tribal lands to enhance resilience against wildfires. It establishes a comprehensive framework for identifying and addressing high-priority firesheds, creating a new interagency Fireshed Center to provide data-driven predictive services and coordinate wildfire and smoke management across jurisdictions. A publicly accessible Fireshed Registry will track wildfire exposure, hazardous fuels management activities, and the status of related environmental reviews. The bill mandates shared stewardship agreements with states and Indian Tribes for joint fireshed assessments, which will identify wildfire risks, at-risk communities, and prioritize management projects. It significantly streamlines environmental review processes for designated fireshed management areas and projects by exempting designations from NEPA and expanding the use of categorical exclusions, increasing acreage limits for certain projects from 3,000 to 10,000 acres. This aims to expedite hazardous fuels reduction, creation of fuel breaks, and removal of hazard trees. To enhance collaborative efforts, the bill modifies Good Neighbor Agreements to include special districts and allow revenue retention for road construction or decommissioning, extending their duration. It also reforms stewardship contracting by allowing longer contract terms and providing cancellation costs for long-term agreements. Intra-agency strike teams are authorized to accelerate environmental reviews and project implementation, while the Joint Chiefs Landscape Restoration Partnership and Collaborative Forest Landscape Restoration programs are expanded and extended. The legislation introduces a strategy to increase the use of livestock grazing for wildfire risk reduction and establishes a Water Source Protection Program to safeguard municipal and agricultural water supplies. It also includes significant litigation reforms, limiting judicial review of covered agency actions by requiring plaintiffs to demonstrate likely success on the merits and balancing the short- and long-term ecological effects of proposed actions. Furthermore, it restricts the reinitiation of Endangered Species Act consultations for approved forest plans under specific circumstances. For community protection, the bill creates a Community Wildfire Risk Reduction Program to coordinate interagency efforts in the wildland-urban interface, supporting fire-resistant building methods and hazardous fuels management. It also establishes a Community Wildfire Defense Research Program to advance innovative designs for wildfire-resistant structures and communities, including a prize for groundbreaking solutions. Provisions are made to streamline vegetation management for electric utility rights-of-way and establish a categorical exclusion for these activities. Transparency and technology are addressed through initiatives like the "Seeds of Success" strategy to boost the domestic seed supply chain for native and fire-resistant plants. A program is established to support priority reforestation and restoration projects on Department of the Interior lands. The bill also mandates accurate hazardous fuels reduction reports, requiring standardized data collection and annual reporting to Congress on acres treated, costs, and effectiveness. A public-private pilot program is created to deploy and demonstrate new wildfire prevention, detection, and mitigation technologies. The bill promotes biochar innovation through demonstration projects and research grants, focusing on its development and commercialization for forest health, carbon sequestration, and agricultural uses. It also includes a comprehensive White Oak Resilience subtitle, establishing a White Oak Restoration Initiative Coalition, pilot programs for restoration on federal lands, and a grant program for white oak regeneration. Finally, the bill mandates the development of a Wildland Fire Management Casualty Assistance Program to provide support and resources to the next-of-kin of firefighters and wildland fire support personnel injured or killed in the line of duty.
