Welcome to the University of Northern Colorado campus, recognized as a Tree Campus USA for its commitment to tree preservation, care and community involvement.

Each day, visitors, students and community members travel the sidewalks of UNC’s landscape and pass by trees that have grown here for decades, sheltering and shading the many who have walked this way before. One silver maple, planted in the 1890s, has literally grown with the campus, standing sentinel through UNC’s history.

With nearly 3,700 trees gracing UNC paths, this guide of three tree tours will help you find and learn about some of the most unique species growing here. Whether you’re walking the trails beneath the leafy green canopies of summer, the bright shades of autumn, the bare-branched trees of winter or the blossom-laden trees of spring, we hope you’ll enjoy the long-standing and continuing commitment UNC has for its green spaces, landscapes and natural beauty.
