The International Society of Arboriculture’s Annual International Conference and Trade Show is one of the world’s premier gatherings of arboriculture professionals, where practicing arborists and urban foresters come together with top researchers and educators to learn the latest in research, technology and innovations in arboriculture and urban forestry.

International Tree Climbing Championship (with Arbor Fair & Expo): Friday, July 28-Sunday, July 30 at the U.S. National Arboretum.

* Free educational opportunities include tree/plant ID walks at the National Arboretum and a Bonsai 101 workshop.

Tree Anatomy workshop: This intensive, three-day Tree Anatomy workshop (Friday-Sunday, July 28-30) will teach reading trees from the inside-out, helping arborists more accurately diagnose tree health and vitality issues.

Dozens of hands-on activities and practical demonstrations are planned.
