The presence (or lack) of big, beautiful trees significantly influences property values. They represent a source of potential liability for public works agencies, and are under greater stress than ever from climate change and invasive insects. Enhance the benefits, health, and longevity of your community’s canopy with the International Society of Arboriculture’s Tree Risk Assessment Qualification program. The two-day course is followed by a ½-day assessment that includes both written and field components. For more information, view the Tree Risk Assessment Qualification Handbook.
