Tree inspectors survey community tree populations to identify and manage disease and insect problems. They also provide recommendations for tree health and care. Tree inspectors proactively monitor for new exotic insect and disease problems such as emerald ash borer, Asian longhorned beetle, and sudden oak death.
To be certified as a new tree inspector, applicant must pass an examination that measures knowledge in shade tree pest identification and management. Exams are given at the end of a new inspector training workshop. Applicant must pass the examination with a score of 70 percent or better to become certified. The workshop attended will include basic instruction so that applicant can demonstrate the following qualifications:
Be able to identify all native tree species, with or without leaves, and all felled or downed trees with bark intact common to your work area.
Know and understand the biology of Minnesota's most common shade tree pests.
Be familiar with symptoms of oak wilt and Dutch elm disease, and be able to identify other problems affecting oaks and elms.
Know the proper method of collecting samples for disease diagnosis.
Know the approved control methods for these common tree pests.
Be familiar with recommended tree species used in replanting programs, their planting requirements, and the care of these trees after planting.
Training workshops are conducted in cooperation with the University of Minnesota Forest Resources Extension and Outreach. Testing is generally conducted in the afternoon of the workshop day. The tree inspector examination covers shade tree statutes, shade tree pest management, tree identification, and firewood identification.
