USFS National Seed Laboratory

The NSL is cooperatively funded by the Forest Service’s National Forest System, Research and Development, and State and Private Forestry deputy areas and administratively attached to the Cooperative Forestry Unit in the Southern Region. The NSL develops protocols for seed handling, germination, and storage of a variety of native forest plant seeds, ranging from commercial timber species to herbaceous understory plants. The NSL provides training materials, workshops, and customized individual training programs to United States and international seed workers, and collaborates with research and production facilities nationwide.
