Project Learning Tree

Project Learning Tree (PLT) is an award winning, multi-disciplinary environmental education program for educators and students in Pre-Kindergarten to grade 12. PLT, a program of the American Forest Foundation, is one of the most widely used environmental education programs in the United States and abroad. PLT continues to set the standard for environmental education excellence.

PLT meets state and national education standards. The curriculum materials provide the tools educators need to bring the environment into the classroom and their students into the environment. Topics range from forests, wildlife, and water, to community planning, waste management and energy.

PLT is a network of 3,000 grassroots volunteers and over 120 state coordinators that work with formal and nonformal educators, school staff, state agencies, foresters, businesses, civic organizations, museums, nature centers, and youth groups to provide professional development programs. To date, more than 500,000 educators are trained in using PLT materials, reaching approximately 26 million students in the United States and abroad.
