Emerald Ash Borer in Minnesota

Emerald Ash Borer (EAB) is an invasive insect that has killed millions of Ash trees throughout the Eastern U.S. and Canada. Since 2009, EAB has spread through 46 Minnesota counties. EAB is present throughout Anoka County and the Twin Cities Metro. Our state is home to over 1 billion Ash trees, all of which are vulnerable to EAB infection. 

Trees affected by EAB dry out and rot quickly, creating public safety hazards. If allowed to decay, these conditions can cause trees to become dangerous to cut. Removing ash trees in high traffic areas including along public trails and neighborhood streets is a top safety priority. 

Help Stop the Spread!

You can help contain the spread of Emerald Ash Borer throughout the state. Avoid cutting and pruning Ash trees from May 1 through September 31 as EAB insects are most active during this time. Do not transport firewood off the site where it was collected. The Twin Cities metro and much of Eastern MN is within an EAB quarantine zone. Transporting firewood out of this area risks spreading this forest disease. 

Current Projects & Volunteer Opportunities

ACD was a recipient of the MN Dept of Natural Resources "ReLeaf 2023" grant to replace Ash trees at King's Island in Anoka. Trees close to trails and the accessible duck blinds were removed in early 2024. New trees will be planted in 2025 with the help of volunteers. Sign up to plant trees as a volunteer here
