European Elm Scale Control Trials
Beginning Wednesday, June 6th, City Forestry will be participating in European Elm Scale Control trials in cooperation with Rainbow Tree Care, Davey Tree Care and CSU. There will be 5 different protocols used that will involve soil drenching right at the base of certain trees, trunk treatments on certain trees, foliar spraying on some trees and trunk injections on others. The chemicals to be used are all approved for use on 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 the research. These treatments should pose no significant risk to park visitors and adjacent property owners. The soil injections will be supervised on June 6th and the spray application will be performed in the early morning on June 7th (weather dependent). All rules and application laws will be strictly adhered to by all involved.
Call Molly Roche, Forestry Specialist (224-616-1992) with any questions.
Invasive Insect Alert: Emerald Ash Borer (EAB)
This small beetle, originally from Asia, is responsible for killing over 50 million Ash trees in the United States. Many Eastern and Midwestern municipalities have lost nearly all of their Ash trees due to this deadly pest. Emerald Ash Borer is now present in Boulder, Colorado. The State Department of Agriculture and USDA/APHIS have issued an Ash Quarantine for all of Boulder County, which prohibits the movement of any Ash material out of the Quarantine Area.
Experts agree that Emerald Ash Borer will reach Fort Collins through natural spread or through the transport of infested Ash material into our City. CSU Entomologists tell us it is not a matter of "if"; it is a matter of "when". So, what impacts will EAB have on Fort Collins? Eighteen percent of City-owned trees in Fort Collins are Ash; that means nearly 1 out of every 5 trees on public land have the potential to be infested and killed! We suspect that the percent of Ash on private property may be the same or even higher. In an effort to determine how many Ash are on private property, the Forestry Division will initiate an analysis of private property trees in 2015. What can you do to help? Be aware that we may contact you to seek permission to enter your property and collect data for the analysis. We will contact you ONLY of your property is selected as part of the sampling plan. Also, pass the word that moving ash material, such as logs, branches or firewood, threatens Colorado's urban forests.

Private Trees
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.
Limbs
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.
