The tree care industry generates a significant amount of urban wood, which includes tree debris from trimming and removals. Without proper recycling efforts, most of this material ends up in landfills.

At CAA, we prioritize mental well-being and believe in second chances. Arboriculture is more than a career—it’s a path to stability, purpose, and growth, especially for those in recovery or reentering society.

Pesticide application is a regulated profession requiring specific training and certifications. Below is an overview of the licensing programs offered by the Colorado Department of Agriculture and through some employers.

CAA is a member-driven organization that relies on passionate volunteers and dedicated professionals.
