    Expert Express and Four O'Clock Forum: Legends of Arboriculture


    The “Legends of Arboriculture” Expert Express will offer participants a unique view about where the arboriculture industry has been, and where our panel sees it going over the coming decades. This special session will include practical, theoretical, international, and historical perspective-type discussions. This session is scheduled for Monday, August 4, from 3:30pm-5:00pm.

    During this Expert Express, industry leaders and notable presenters from the conference will have the opportunity to deliver a very brief (5-8 minute) description of their research or topic of interest, followed by a one-hour break out session (Four O'clock Forum) where participants have the opportunity to talk about the individual presenter’s topic in a small-group setting. After the initial brief presentations, the presenters will fan out, where participants will then be able to approach speakers with their similar interests and move around the room to hear conversations about the various topics. This small group component is scheduled to last one-hour.
