TREE Fund Webinars

TREE Fund webinars bring you the latest in tree research, directly from the scientists themselves.

TREE Fund’s one-hour webinars are free and offer 1.0 CEU (only for live broadcast) from the International Society of Arboriculture (ISA), the Society of American Foresters (SAF), the National Association of Landscape Professionals (NALP) and sometimes the Landscape Architecture Continuing Education System (LACES). See webinar descriptions for specifics. Space is limited, and pre-registration is highly recommended; in doing so, you’ll receive a reminder email the day before the broadcast.

Download the ISA CEU attendance form here.

Many thanks to our webinar hosts Alabama Cooperative Extension System and Utah State University Forestry Extension 

Future Webinars

Registration will open approximately one month before the program date.



Why Do Tree Branches Fail?

Thursday, March 26, 2020, at 12 p.m. Central

Greg Dahle, PhD, West Virginia University

Register here. 

We will explore how researchers from ecology, forestry and arboriculture have utilized biomechanics to understand how trees contend with the forces mother nature can throw at them during the long-life span. Biomechanics approaches integrate biology and engineering principles to explore how organisms deal with their environment. We will explore two studies that examine how loads move through a branch union/fork. A close relationship was found between aspect ratio and different failure types and we will discuss how this information can help define the point at which a weaker co-dominant fork occurs.

Greg Dahle is an associate professor at West Virginia University where he teaches courses in arboriculture and urban forestry. Greg’s research lab utilizes a biomechanical approach to understand how trees grow and survive environmental loads, as well as broader urban forest management issues. Greg has worked as a commercial and utility arborist and is an ISA Board-Certified Master Arborist.
