Dutch Elm Disease Control

Control & Prevention Program
The City of Coon Rapids maintains an aggressive approach in controlling the spread of Dutch Elm Disease (DED). Although Coon Rapids has lost thousands of elms due to the spread of DED, the Forestry Division has consistently implemented a program to prevent the further spread of DED through the following steps:
  1. Inspection
  2. Removal
  3. Re-planting
  4. Sanitation
  5. Public education
All elms are inspected throughout the city by tree inspectors licensed and certified by the Minnesota Department of Agriculture. Inspectors look for early symptoms in the spring on trees beginning to leaf out that may show signs of leaf wilting or dieback. Trees are inspected again later during the growing season. Leaf and/or twig samples are taken from suspect trees and diagnosed for possible DED infection. Firewood piles are also inspected for elm wood that may still have the bark intact allowing for a breeding zone for the elm bark beetles that carry the fungus.


If a tree is found to be infected with the DED fungus, it is measured and clearly marked for removal. Property owners are notified by certified mail and are given 20 days from receipt of notice to have the diseased tree taken down and removed.

For a current list of tree contractors licensed in the City of Coon Rapids, contact our Public Works Office at 763-767-6462 or City Forester at 763-767-6455. You may also view or download the list of Tree Contractors (PDF).

Trees removed on public property due to disease or other damage are promptly replaced by forestry personnel on an annual basis. Factors such as power lines, existing species, available space, and soil conditions are considered when determining if a tree should be replaced in its previous location. If you have recently lost a boulevard tree, please notify the City Forester or Public Works Office.

As noted above, it is unlawful in Coon Rapids to have elm wood (with bark intact) on your property elm wood for firewood or any other use. Insects carrying the Dutch Elm Fungus must regenerate beneath the bark of elm wood. If you eliminate the bark, you remove the chance of the beetle reproducing and further spreading the disease.

Elm wood can be disposed of at the Bunker Hills Compost and Wood Disposal Site located at the intersection of Hanson Boulevard and 133rd Avenue. For more information, please call 763-767-7964.

It is unlawful for anyone to prune or trim any elm tree from April 1 - August 31 since the beetle needs an open wound or cut to enter the tree, and this is the time frame that the beetle is active.
