Does the USDA Forest Service provide trees and plant materials for outdoor classrooms?
The USDA Forest Service does operate a few nurseries, but the trees are only for planting on National Forest Systems lands. For sources of plant materials suited for your region, check with your local nurseries and garden stores. They specialize in growing large trees adapted to your local growing conditions and offer various sizes of trees and shrubs. Some State Forestry Divisions and Conservation Districts offer tree and shrub seedlings for conservation plantings, while seedlings are relatively inexpensive they do not make as big of a visual impact.
