The Reforestation, Nurseries, and Genetic Resources Support Act of 2026 aims to bolster national reforestation efforts by strengthening nurseries and seed orchards. It directs the Secretary of Agriculture to establish broad partnerships with various entities, including Federal and State agencies, Indian Tribes, and private nurseries, to provide training, technical assistance, and research for natural regeneration, reforestation, and agroforestry programs. A key provision is the creation of a grant program, to be established within two years, offering financial assistance to eligible recipients such as State forestry agencies , Indian Tribes , and experienced private nurseries . These funds can be used to develop or expand nursery production capacity and infrastructure, improve seed collection and storage, increase seedling production and distribution, and promote workforce development across the reforestation supply chain. The bill also emphasizes promoting information sharing to advance technical knowledge and address climate change impacts on tree genetics, while coordinating Department of Agriculture efforts to resolve supply chain challenges. Additionally, it streamlines seed collection permits on National Forest System lands and authorizes up to $5,000,000 annually from the Reforestation Trust Fund to implement these initiatives.
