Colorado Tree Coalition is a nonprofit organization dedicated to urban and community forestry, tree preservation, and ecological restoration across the State of Colorado. Founded in the late 20th century, the Coalition coordinates volunteers, municipal agencies, and conservation groups to increase canopy cover, mitigate urban heat, and promote biodiversity in metropolitan and rural landscapes. Working with federal, state, and local partners, the Coalition advances best practices in tree planting, care, pest management, and public education.

History

The organization traces its roots to regional tree boards and civic associations that responded to canopy loss driven by drought, wildfire, and development in the 1990s. Early collaborators included the City and County of Denver, the Colorado State Forest Service, and urban planners from the University of Colorado Denver who sought to replicate models from the Arbor Day Foundation and the National Arbor Day Foundation. Over time, the Coalition formalized partnerships with municipal arborists from Colorado Springs, Aurora, and Boulder and with conservation organizations such as The Nature Conservancy and American Forests. Major statewide events in the early 2000s—like wildfires in the San Juan Mountains and the Hayman Fire—prompted expanded programs with the United States Forest Service and the Federal Emergency Management Agency to integrate urban forestry into disaster resilience planning.

Mission and Programs

The Coalition’s mission emphasizes increasing tree canopy, conserving riparian corridors, and enhancing community resilience. Core programs include urban canopy assessments conducted in collaboration with the Colorado State Forest Service and academic partners at Colorado State University, tree planting initiatives modeled on standards from the International Society of Arboriculture, and pest-response protocols coordinated with the United States Department of Agriculture’s Animal and Plant Health Inspection Service. Educational offerings range from volunteer tree steward training with local conservation districts to schoolyard greening projects partnering with Denver Public Schools and the Colorado Department of Education. Public outreach campaigns reference guidelines from the Environmental Protection Agency and climate adaptation frameworks promoted by the Rocky Mountain Climate Organization.

Organizational Structure and Governance

Governance is provided by a board of directors drawing members from municipal arboriculture offices, nonprofit conservation groups, and academic institutions such as the University of Colorado Boulder. Operational staff manage regional program coordinators who work with county extension offices, municipal parks departments, and Native American tribal governments including the Ute and Southern Arapaho communities on culturally informed planting practices. Advisory committees include specialists affiliated with the International Society of Arboriculture, the Society of American Foresters, and landscape architecture programs at Colorado State University. The Coalition maintains tax-exempt status and follows nonprofit compliance frameworks specified by the Colorado Secretary of State and guidelines from the Internal Revenue Service.

Major Projects and Initiatives

Significant initiatives have included a statewide urban tree canopy mapping project conducted with satellite imagery partners and remote-sensing researchers from the National Aeronautics and Space Administration and the United States Geological Survey. Restoration projects following the High Park Fire and the Marshall Fire engaged the Colorado State Forest Service, the National Forest Foundation, and local watershed districts to reestablish native riparian vegetation and mitigate erosion. The Coalition has spearheaded metropolitan tree planting campaigns in collaboration with Denver Parks and Recreation, Boulder Open Space and Mountain Parks, and El Paso County Parks, as well as pilot programs to integrate green infrastructure with stormwater management alongside the Environmental Protection Agency’s urban watershed programs.

Partnerships and Funding

Funding streams combine grants from state agencies such as the Colorado Department of Natural Resources and federal sources including the United States Forest Service and the National Fish and Wildlife Foundation. Corporate sponsors and philanthropic partners have included the Gates Family Foundation, the Boettcher Foundation, and energy utilities like Xcel Energy that support urban cooling initiatives. Collaborative memoranda of understanding exist with municipalities including the City of Fort Collins and the City of Pueblo, and programmatic alliances involve academic research partnerships with Colorado State University, the University of Denver, and Metropolitan State University of Denver. Volunteer mobilization leverages networks with AmeriCorps, local chapters of the Sierra Club, and community colleges running horticulture programs.

Impact and Conservation Outcomes

Measured outcomes reported by the Coalition and partners include increased canopy cover percentages in targeted neighborhoods, reduced urban heat island effects quantified by thermal imaging work with the National Oceanic and Atmospheric Administration, and improved stormwater retention through bioswale and green-street installations. Ecological benefits documented in partnership reports cite enhanced pollinator habitat, greater carbon sequestration estimates developed with modeling tools from American Forests, and reduced soil erosion in riparian corridors. Social impacts include expanded environmental stewardship among underserved communities through outreach with the Colorado Health Foundation and documented public-health co-benefits in collaboration with local hospitals and public-health departments. The Coalition’s work has influenced municipal tree ordinances in several Colorado cities and provided a template for climate-resilient urban forestry adopted by regional planning commissions.
