Invasive Insect Alert: Emerald Ash Borer (EAB)


The Forestry Division is responsible for trees owned by the City. These are street trees located between the sidewalk and curb, trees in city medians, in parks and those located on other City property. The Forestry Division appreciates hearing from citizens about the location of storm-damaged City trees. Contact the Forestry Division office at 970-221-6660 to report a broken City tree.

Property owners are responsible for their trees and can contact a private licensed tree service for pruning or removing a storm-damaged tree. Businesses that make tree pruning or removal cuts at 10 feet or greater above the ground when working within the City limits are required to be licensed by the City of Fort Collins. Licensed tree services have the skills needed to prune or remove a tree correctly.  Homeowners can prune their own trees. Tree work can be dangerous and if not done correctly can further damage a tree. Using a skilled professional to do tree work can help insure that a damaged tree has the best chance for recovery.


Branches from private trees can be chipped by a private tree service or hauled to Hageman Earth Cycle located on East Prospect.  Limbs can also be hauled to the Larimer County landfill.

Downtown Street Tree Removal and Replacement Project

Due to existing underground utilities, the City of Fort Collins Forestry Division will need to reschedule the tree removal and replacements for the following sites:

  • Fish, 150 W Oak St.
  • Tasty Harmony, 160 W Oak St.
  • Slyce Pizza Co.,163 W Mountain Ave.
  • John Atencio, 164 N College Ave.
  • Salus, 238 Walnut St.
  • Curiosities, 242 Walnut St

When underground utilities reside within a stump grinding site or tree planting location, Forestry takes added safety precautions and potholes the site. Potholing is a procedure that utilizes pressurized water and a vacuum to remove the soil perpendicular to the underground utility. This is to ensure that the underground utilities are well below our working depths to keep our crews, contractors, passerby’s and businesses safe during the stump grinding and planting process.

The rescheduled tree work will be announced as soon as possible. 

European Elm Scale Control Trials

On Wednesday, June 6, City of Fort Collins, Forestry Department participated in European Elm Scale Control trials in cooperation with Rainbow Tree Care, Davey Tree Care, and CSU. There were 5 different protocols used which involved soil drenching at the base of certain trees, trunk treatments on certain trees, foliar spraying on some trees, and trunk injections on others. The chemicals used are all approved for elm scale and will be applied in a manner to minimize exposure and risk to the public. However, due to the nature of the trials the chemical names will not be released until after the trial. This helps to eliminate bias and give proprietary information to research. These treatments pose no significant risk to park visitors and adjacent property owners. The soil injections were supervised on June 6 and the spray application was performed on June 7.
