Mile High Million Programs

Trees for Energy Savings

Our Trees Count!

We will never be able to plant a million new trees without the help of partners. Learn more about our Green Industry partners that register their trees toward The Mile High Million goal.

Community Foresters

Are you interested in participating in a program that teaches you about trees and provides volunteer opportunities to put your knowledge to good use? Learn more about Community Foresters.

Cool Schools Tree Planting Program

Trees are great resources for sparking the imaginations of children, igniting life long interest in disciplines like science, art, literature, geography and math. Learn more about how to engage your students by participating in our Cool Schools Tree Planting program.

Project Learning Tree

Project Learning Tree® (PLT) is an award winning, multi-disciplinary environmental education program for educators and students in PreK-Grade 12. The Mile High Million partners with PLT to provide free workshops for teachers in the Denver Metro area. Learn more about how to make PLT work for you and your students.

Educator Resources

Long after the million tree goal has been reached, a new generation of stewards will be needed to care for the trees. Visit our Educator Resource Center to learn more about the resources available for teachers to use inside and outside the classroom to create future stewards.
