The City recognizes that the urban forest is crucial to environmental and community well being. Increasing and sustaining Evanston’s tree population improves air quality, stormwater absorption, livability, and reduces adverse urban impacts on humans and key species. Currently, trees face threats such as invasive pests, disease, and intensifying weather events due to climate change. To combat this, the city will adhere to Climate Action and Resilience Plan’s goal of planting 2,000 new trees by 2050 along with the additional actions listed in the plan. Below is a list of threats trees face and resources regarding their preservation.
Threats to Evanston Trees
- Emerald Ash Borer (EAB) is a non-native pest that feasts on ash trees.
- Dutch Elm Disease is a destructive wilt disease caused by two fungi.
- Extreme cold, heat, and storms place excess strain on Evanston’s trees. The Hazard Specific Preparedness Page has the information you’ll need to stay protected.
Preserving Our Urban Forest
- Trees for 2050 is a publication developed by the Chicago Botanic Garden that guides tree selection for climate resilience
- I Heart Evanston Trees works to provide a number of benefits to our community’s ecosystem which can be enjoyed by wildlife and citizens alike.
- The Parkway Tree Planting program is designed to replace lost trees in a way that is good forestry practice to help maintain our Urban Forest. Why? Sadly, Evanston has been losing trees at a high rate due to circumstances such as disease or storm damage.
- TreeKeepers are volunteers affiliated with Openlands who are trained in keeping trees healthy by administrating proper care and recognizing and reporting threats.
- Dutch Elm Disease Insurance is provided by the City of Evanston for residents with Dutch Elm trees on their private properties to protect against the possibility of tremendous costs required to remove the infected trees.
Other Urban Forest Resources
- The Sustainable Pest Control and Pesticide Reduction Policy calls for the reduction of pesticide application on City-owned property.
