This bill amends the Cooperative Forestry Assistance Act of 1978 to establish the Neighborhood Tree Fund , aimed at providing financial assistance to eligible entities to significantly increase and improve the overall health of tree canopies within communities. Congress finds that healthy urban forests offer substantial benefits, including improved public health, air quality regulation, urban heat island mitigation, and stormwater management, while also addressing historical inequities in tree canopy distribution. Assistance from the fund will be available to States, Indian Tribes, and local units of government , along with approved organizations and community tree volunteer groups. The Secretary, in consultation with the Secretary of Housing and Urban Development, will set requirements for receiving aid, including community engagement, tree canopy assessments, and climate change science integration. Priority will be given to projects in low-income census tracts , formerly redlined areas, or communities with lower tree canopy and higher summer temperatures, as well as those optimizing climate mitigation and public health outcomes or advancing urban agroforestry. The bill authorizes substantial appropriations for the Neighborhood Tree Fund, starting with $100 million in fiscal year 2025 and escalating to $700 million by fiscal year 2029. Additionally, it modifies the composition of the National Urban and Community Forestry Advisory Council by increasing its membership and ensuring representation from residents of smaller communities and low-income communities. These changes aim to accelerate federal actions to enhance urban forest health and resilience, particularly in underserved areas.
