The City of Fort Collins has 1,300 vacant tree sites - trees that once existed but haven't been replaced.
Ash Trees make up 33% of our canopy with over 7,000 in the City's inventory, and they are in danger. The Emerald Ash Borer (EAB) is a wood-boring beetle that's made its way to Colorado. To keep our tree canopy lush and healthy, join us and plant a tree resistant to EAB.

The Forestry Division strives to sustain a safe, healthy and attractive urban forest through frequent and sound management practices. Here are some of the ways the Forestry Division accomplishes this objective:

  • A five-year pruning rotation to improve health of the urban forest
  • Tree Risk Assessment of aging or declining trees to provide a safe community
  • Through tree replacement and diversifying our species palette to increase resiliency
  • Insect and disease identification and control
  • Licensing arborists to work within City Limits to ensure quality arboricultural work and that industry standards are met
  • Working with developers and landscape contractors to ensure diverse species are planted properly within the right-of-way (between curb and sidewalk) and in new developments
  • Public education and outreach to engage the community in learning the benefits of the urban forest

Trees are public infrastructure that appreciate in value as they grow. This is why it is important to protect and maintain what we have. Our urban forest provides endless benefits: by sequestering and storing carbon, reducing storm water runoff, reducing energy costs as well as heat island effect through shading and of course producing oxygen.
