Since 1976, we have connected Coloradans to nature through the lens of trees and forests. We offer educational resources and professional development to educators, parents and community leaders across Colorado.
Mission: Colorado Project Learning Tree uses trees and forests to advance environmental knowledge and skills and promote sustainable practices and actions for all.
Professional Development
We support educators in all their forms, ranging from formal PreK-12 teachers and college students to nonformal instructors like youth group leaders (Scouts, 4-H, after-school programs), natural resource professionals, families and place-based educators at museums, zoos and nature centers.
Through PLT’s flexible training—available in-person, online or blended—you will:
- Build Confidence: Gain the skills to lead students in outdoor learning environments.
- Adapt to Any Setting: Learn to tailor environmental education techniques to your unique audience, whether in a classroom, a forest or a community center.
- Connect: Collaborate with fellow professionals to experience activities firsthand and explore real-world ways to bring PLT into your programs.
Educator Resources
We offer award-winning, multi-disciplinary resources from the national Project Learning Tree program that make teaching and learning fun. Designed to be “plug and play,” our flexible lessons are easy to integrate into your existing curriculum or teach as standalone units.
- Interdisciplinary & Standards-Aligned: Our learner-centered activities teach students how to think—not what to think—about the environment. All lessons are correlated with national and state standards, incorporating STEM, language arts, social studies and career exploration to build 21st-century critical thinking and analytical skills.
- Flexible & Adaptable: We know your time is valuable. Our resources are designed for easy implementation and can be leveled up or down to meet the specific needs of your learners, regardless of the setting or grade level.
- Whole-Student Wellness: Beyond academics, PLT connects students to nature to foster social and emotional growth. Studies show that nature-based learning improves student behavior, reduces stress and increases engagement, leading to higher performance across all subject areas
PLT Community
Our community is a wide-reaching network of educators, dedicated volunteer facilitators who deliver our professional development and help grow our reach, and a statewide advisory council that provides strategic guidance for Colorado PLT. We offer multiple ways to stay engaged—from subscribing to our newsletter for the latest resources and tips to taking on leadership roles that help shape the future of our program. Together, we work to ensure every student in our state has the opportunity to connect with trees and forests through high-quality environmental education.
