CHampion Tree Program
Similar to the National Champion Tree Registry, CTC’s Champion Tree Program maintains records of the three largest trees for each species in the state. These trees are the largest trees of their species in the state and are representative of Colorado’s rich history and diverse ecosystems. By documenting these important trees, we can promote their conservation and protection for future generations of Coloradoans.
