Denver Parks & Recreation Office of the City Forestry has identified conifer trees in the Denver area infected with the Ips engraver beetle. The bark beetle is always present in Denver’s urban forest and flares up every 9 to 10 years. The beetle rarely attacks healthy trees and mostly occurs in newly transplanted or stressed trees. In 2002, we lost over 300 spruce throughout the city; in 2012, we lost over 200. Currently, we have documented about 74 this year throughout the city and the park system.
Denver Forestry’s strategy for the park and parkway system is to remove infested trees quickly, inspect existing trees, and apply a preventative treatment to trees that are in proximity but not infested. All removed trees will be replaced.
The Ips engraver beetle is 1/8 to 3/8-inch-long, reddish-brown to black in color and lives under the bark of conifer trees, producing girdling tunnels that cause foliage discoloration, crown dieback, eventually killing the tree.
To aid in the prevention of beetle infestation, practice proper tree maintenance including adequate watering, pruning out deadwood, protecting the tree from injury from construction activities, mechanical damage and soil compaction.
Preventative treatments may be helpful for other trees but once infected, no chemical treatment exists, and swift removal is the only option to keep the beetle from spreading.
To identify if your tree may be infected, look for fading needle color at the very top of your conifer or signs that the top of the tree is dead. If you suspect your tree is infected, contact a licensed and insured tree company for inspection. Colorado State University Extension also provides information on this pest and others. https://extension.colostate.edu/
When the founders of the Denver Country Club (formerly Overland Park Club) purchased the 120 acres for the Club in 1902, they also formed the 4th Avenue Realty Company and acquired additional land to the north for housing development. William E. Fisher was hired to establish the layout of the project. His design incorporated a series of landscaped parkways from 1st to 4th Avenues along Franklin, Gilpin and High Streets, expanding green spaces within the City of Denver.
Today these parkways are managed by Denver Parks and Recreation as part of Denver’s urban park system. Because they are an important asset for our neighborhood, representatives of the CCHN Board work closely with the Operations Supervisor of Parks & Recreation to protect and maintain these historic parkways.
Concerns about the condition of the parkways were raised this year by several CCHN residents. CCHN President Diane Woodworth-Jordon and I met with the Parks Supervisor to establish a plan to rejuvenate this aging landscape, which incorporates lawn, shrubs and trees. Acting quickly on the plan, Parks & Rec has already redefined the tree rings and shrub beds and will mulch these areas in the spring, when they will plant replacement shrubs.
The lawns have been aerated and over seeded. This winter, Denver Forestry will prune trees. Tree replacement is on a rotating schedule by zones throughout the City. This part of Denver isn’t up for replacement for a few more years. We are working with Forestry to maintain a list of trees to replace. Also on the winter schedule is resetting of the remaining concrete “Dragon’s Teeth” placed at the north and south ends of each parkway so that they stand upright.
Parks and Rec has asked all residents to call 311 if they see sprinkler issues or fallen trees in the parkways. They also request that residents not put their own broken branches or trees in the parkways for cleanup. There aren’t enough funds or personnel to handle park debris after a major storm, so removal of residential trees and branches needs to be the responsibility of the homeowner.
When Spring 2020 arrives, the parkways of Franklin, Gilpin and High Street should be bursting with new growth and again beautify the neighborhood.
If you have interest in being part of our neighborhood beautification effort, please contact our neighborhood president for more information about how you can become involved.
Potential flooding of Cherry Creek Trail on Wed. May 22, 2019: Annual reservoir sediment flush
WEDNESDAY, MAY 22: the U.S. Army Corps of Engineers will conduct their annual sediment flush of the Cherry Creek Reservoir & Dam. As always, the released water is not expected to reach the Cherry Creek Channel until Wednesday evening, at which point the trail could experience flooding.
This year is a low-flow year, so any flooding should be minimal—operations crews anticipate that the Cherry Creek Trail will remain open but remind everyone to use extra caution if water is on the trail, and to consider using an alternate route if possible. If necessary, please use the sidewalk along Speer Blvd. Crews will be out early on Thursday morning to address any needed cleanup. Thanks for your patience!

Our beautiful neighborhood is a hotbed for swarming bees in the late Spring due to the plentiful gardens and trees. In April, May or early June, you might see a swarm take residence in a nearby tree or other temporary home.
Bees swarm when there are too many bees in the hive. The queen leaves with half of the hive bees, allowing another queen to take residence. The swarm heads for a temporary spot to rest while the scout bees seek a more permanent home, such as inside a rotted out tree.
There is nothing to fear. Bees are in a pretty docile mood when they are swarming. However, do not consider moving them, and do not spray them with anything. You don’t want to anger them, and do not want to kill these precious insects. Instead, call the Bee Swarm Hotline at 1-844-SPY-BEES and someone will come to remove the bees. They will find the lot a good home with a beekeeper, allowing them to have a better chance of making it through the next winter.
To learn more about bees and beekeeping, visit coloradobeekeepers.org or take a class at the Botanic Gardens or To Bee or Not to Bee in Littleton.
