Asian longhorned beetle (ALB) has not been found in Wisconsin, but early detection is critical to eliminating it from infested areas. Forest Health workers from Wisconsin, Michigan, Minnesota and Manitoba, Canada, recently had the opportunity to visit an active ALB infestation in South Carolina to learn how to identify infested trees. This experience will greatly enhance staff’s ability to detect ALB and respond rapidly.
Beginning July 1, 2026, cities, villages, towns, counties, tribes and 501(c)(3) nonprofit organizations conducting projects in Wisconsin can apply for a regular or startup 2027 Wisconsin Department of Natural Resources (DNR) Urban Forestry grant. 
With recent storms passing through Wisconsin, communities may still be working on clean-up. Depending on the intensity of the storms and the condition of the trees, damage from high winds, heavy rainfall, hail and lightning can be quite severe. Cracked or broken branches, trunk damage and root failure are some of the main concerns, but also the risk and liability of damage to people and property.
