This is made possible not only by actions within the forestlands of Colorado, but also by initiating face-to-face conversations with surrounding community members, landowners and other agencies. Areas in which the CSFS offers leadership and guidance include forest management; wildfire mitigation and community planning; wood utilization CSFS Community Forestry Program Manager Keith Wood teaches an urban and and marketing; outreach and education; community forestry workshop, with Boyd Lebeda, CSFS Fort Collins District and insect and disease detection, forester.

The agency offers technical assistance in urban and community forestry, including tree care and management plans, and is Colorado’s primary provider of seedling trees for conservation purposes such as creating living snow fences and windbreaks, reforesting areas after wildfire and enhancing wildlife habitat. The CSFS works through 19 district and field offices statewide, with a headquarters located in Fort Collins. The agency operates within the Warner College of Natural Resources at Colorado State University and fulfills the responsibilities of the Division of Forestry within the Colorado Department of Natural Resources.

This year’s report offers a special focus on how forests impact and are conversely affected by wildland fire and water flowing through forested watersheds. Between broader sections on fire and water, the report offers a detailed review of 2016 insect and disease activity in Colorado forests. Colorado’s 24.4 million acres of forestland provide immeasurable social, economic and ecological benefits to its citizens and visitors. Forests offer a sustainable wood products industry, diverse wildlife, fresh water and ample recreation opportunities. But they face numerous threats, and can present risks to citizens and visitors.
