We're certainly in the business of adding trees to our environment. In 2006, our Mayor John Hickenlooper introduced a great tree planting program. The goal is to add one million new trees to the Denver metro area by 2025. All new trees count. Schools, residential, parks, etc. If you have a tree planted, please register it. Contractors should also be made aware of this program so they can register all the trees they plant.
To learn more about this program, visit The Mile High Million site.
