Which activities require Maryland Tree Expert licensure?

• A. Planting trees on public property
• B. Inspecting a tree from the street
• C. Performing professional arboricultural services for compensation, including pruning, removal, diagnosis, and treatment of trees on properties
• D. Watering trees

Answer: (C)

Licensure is required when you perform professional arboricultural services for compensation, which means you’re hired to diagnose, prune, remove, or treat trees on someone’s property. Those activities involve specialized knowledge, skills, and safety considerations, so the license verifies you’re qualified to provide that professional service. Planting trees on public property is just planting work and typically not billed as professional arboriculture. Inspecting a tree from the street is only observation and does not involve on-site professional care. Watering trees is routine maintenance and does not include diagnosing or treating problems or performing removals. So the activity that specifically falls under licensure is performing professional arboricultural services for compensation, including pruning, removal, diagnosis, and treatment on properties.
