What is a Minnesota Certified Tree Inspector?

In 1974, the Minnesota Certified Tree Inspector program was implemented as a response to Dutch elm disease (DED) and the emergence of oak wilt (OW). Through the Minnesota Department of Natural Resources and the University of Minnesota Department of Forest Resources, Tree Inspectors receive training and a certification in how to manage epidemic level shade tree pests. They are qualified to first identify existing tree pests/diseases, like DED, OW and emerald ash borer (EAB), in a community. They are then able to offer tree health, care and management recommendations for individual trees or larger stands based on their observations.
