Who We Are

Partnering Cities

The Mile High Million is a regional initiative, which spans the 37 cities and towns in the Denver metropolitan area that are represented by the Metro Mayors Caucus. To help achieve the goal of one million new trees by the year 2025, The Mile High Million supports these metro-area communities by sponsoring and/or funding tree planting events, tracking tree plantings by community, facilitating forestry trainings and coordinating volunteer events.
