While the deadly beetle yet to be detected in Cheyenne, WY, the city is taking a proactive approach to bracing for its arrival, noting that is has been sited in Longmont, CO, as well as Nebraska and South Dakota. The Cheyenne Urban Forestry Division (CUFD) created an EAB plan in August 2019 and has begun implementing several of its initiatives, including removing and replacing ash in poor health and providing outreach to the public.
Using Tree Plotter, an online tree inventory system, the CUFD estimates that about 750 ash trees are on city-owned property and that there are about 5,700 ash trees on private property. Cottonwood – 1,800 on city-owned land and 15,883 on private property – is the city’s dominant tree species.
Measures of the CUFD’s EAB plan include:
- Educating CUFD staff including taking workshops and hands-on training in cities affected by EAB outbreaks such as Boulder, CO, and Longmont. Training included sampling ash trees for the presence of EAB as tree removals or maintenance based on government agency and research programs.
- Conducting inspections and collecting samples of any symptomatic trees reported by citizens or other entities.
- Educating local, licensed arborists to be trained in proper sampling techniques and encourage them to inspect all ash trees as they do tree removals or maintenance. Ask that they report any suspicious tree samples they encounter to CUFD.
- Maintaining EAB traps on city properties.
- Removing and replacing ash trees in fair or worse condition.
- Evaluating ash trees in good condition other pest infestations and treating them as necessary.
- Educating the public to be proactive in managing their ash trees tol lessen the negative impacts of EAB once it arrives.
- Enacting quarantines as deemed necessary to prevent the spread of EAB and associated regulated items beyond the area currently affected.
- Establishing a marshalling yard to store and process ash wood separate from other tree species in a rapid manner to comply with quarantine regulations.
- Implementing an urban wood utilization program.
