Male and female competitors perform five different events during preliminary rounds to qualify for the championship.

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. 

Call Molly Roche, Forestry Specialist (224-616-1992) with any questions.

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.
