Oak and ash comprise a substantial part of the city's urban forest. Unfortunately, new deadly diseases affecting these trees have moved into our area. Maplewood's Diseased Tree Inspection program is designed to slow the spread of:
Emerald Ash Borer-all species of ash (Fraxinus)
Oak Wilt-all species of oak (Quercus)
City Identifies Infectious Trees on Public & Private Land
The City of Maplewood 's certified tree inspector identifies trees on private and public land that are affected by oak wilt or emerald ash borer. By authority granted in Minnesota Statute, the city tree inspector has the right to enter private property to check a tree. Infected oak, ash, or elm with Dutch elm disease may be subject to the City's shade tree disease control program and may require removal of the infected tree at the property owner's expense.
If you are concerned about a tree that may be diseased, please call the Public Works Department at 651-249-2400.
Firewood, including branches from diseased or infested wood, is a known pathway for movement of forest pests and diseases long after a tree has been cut down. City ordinance prohibits storage of diseased firewood. There is a quarantine for Hennepin and Ramsey counties that prohibits the movement of firewood and ash tree parts into or out of the quarantine area without a state permit.
