The certified tree inspector program was implemented in 1974 in response to Dutch elm disease and oak wilt. Since then, hundreds of communities have participated, and there are more than 800 certified tree inspectors in Minnesota. Certified tree inspectors have passed a test in which they demonstrate proficiency in Dutch elm disease and oak wilt management, tree identification, firewood identification, and shade tree management. Tree inspectors must attend annual recertification workshops to learn the latest information on tree care, exotic species management, shade tree management, tree selection, insect and disease identification, tree health care, and other timely topics.
