Project Learning Tree

PLT, an initiative of the Sustainable Forestry Initiative, is an award-winning environmental education program and standards-aligned curriculum.

As the state sponsor of PLT, Maine TREE engages a network of teachers, informal educators, parents, and community leaders throughout the state to “teach students how to think, not what to think.”
