Dutch Elm Disease Insurance for Trees on Private Property

HELPING PROPERTY OWNERS

Dutch elm disease (DED) is a fungal disease that targets elm trees, and primarily American elms. DED spreads easily between trees and quickly throughout a tree, sometimes killing a mature elm tree in one season. The City of Evanston's Forestry Division cares for tens of thousands of trees throughout our parks, public areas, and miles of beautiful parkways. The City manages these trees with regular pruning and other maintenance measures, as well as testing elm trees for DED, and removing public trees which have become too diseased to save. But when DED infects a tree on private property, the property owner is responsible for the cost, which can be quite high.  

To ease this potential financial burden, Evanston Forestry is pleased to offer a Private Elm Tree Insurance Program, which covers the removal of elm trees on private property lost due to DED.

Property owners  locate, measure, and enroll individual trees on their property by June 1 of each year. The City helps to monitor these elm trees, and provides free testing if an insured elm is showing symptoms of DED.

Note: City staff are available to help identify elm trees on private property. Please contact forestry@cityofevanston.org or via  311 if you would like assistance.

If the tree tests positive for DED but symptoms are present in in 5% or less of the tree's canopy, property owners may elect to pay a certified and qualified forestry professional to perform mitigation measures, including cutting out the diseased portion and inoculating the tree. For liability reasons, City staff may not provide any type of care for trees on private property. 

If an insured tree shows signs of infection in greater than 5% of its canopy, it requires removal. The City assumes responsibility for all logistics and costs of removing insured trees to “ground level” by a highly qualified and fully insured tree care company. Property owners may elect to have the remaining stump removed by contracting with a tree care company of their choice, including with the City's contractor at the time of the tree removal.

ENROLLMENT PROCESS

Property owners apply and pay by June 1 of each year. All elm trees must be enrolled by this date to qualify for this insurance, and late submissions will not be accepted. 

To reduce paper consumption and to promote resource conservation, please consider enrolling and submitting your payment online. This option is available for both new and returning participants and the form is accessible here:

To qualify for the 2024-2025 season, all materials must be submitted by June 1, 2024. Late submissions will not be accepted, and there will be no exceptions. 

In early June of each year, Forestry Division staff regularly inspects American elm trees on both public and private property to look for symptoms of DED. When an elm tree is diagnosed with DED and exhibits symptoms in greater than 5% of its canopy, City of Evanston ordinance requires its removal within 30 days.

The City is responsible for removing trees on City property (including parkways), but trees on private property are the responsibility of the homeowner. Removing a mature elm tree can cost $2,000 - $7,000 and beyond for very large trees. Homeowners are responsible for the cost of removing uninsured trees, and the work must be completed within 30 days, as mandated by City ordinance.

Proactively managing the health and maintenance of elm trees will help them to stay as healthy as possible so that they can defend themselves against DED. The City recommends that elm trees be inspected at least every 3 years by a certified and/or qualified arborist. The arborist may recommend maintenance that includes regular deadwood pruning and/or injections that are proven to be 98% effective in preventing initial DED infection.

Tree maintenance should always be completed by qualified, certified, and fully insured tree care professionals. Please note that maintenance is strongly recommended and beneficial to elm trees, but not required for participation in the insurance program.

Homeowners can help all trees by mulching trees correctly, as shown here:
