Forest Health

Restore. Protect. Enhance.

Anoka County Parks works closely with the Minnesota Department of Agriculture, the United States Department of Agriculture, and the Minnesota Department of Natural Resources on monitoring for new forest pest infestations and control practices. One main concern in Anoka County Parks is oak wilt. To actively manage oak wilt, we start by identifying infected sites. Once the infected areas are located, a vibratory plow is used to sever roots to halt the underground spread of the disease. The final step is site sanitation, which is the removal of the diseased wood from the site and mulching the brush.

Another serious concern in Anoka County Parks is Emerald Ash Borer (EAB). EAB was confirmed in Anoka County in 2015 and has been slowly spreading in multiple areas, including our parks. Anoka County has been selectively treating ash trees that are in good condition and provide significant benefit and removing trees in poor condition that may become a hazard as they die off since 2013. As the infestation is progressing and die off is ramping up, trees that will present future hazards to park patrons, staff, and infrastructure will be removed in much greater numbers to ensure safety and protection. As these hazards are abated, we will work to formulate a plan for reforestation of the area most greatly impacted. Staff are always on the lookout for the numerous other pests and diseases that occur in the county. These are addressed on a case by case basis geared to the problem that is presented.
