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 host Alabama Cooperative Extension System.

The Calm Before: Tree Adjustments to Wind & Ice Storm Loads

Register Here

Tuesday, June 2, 2020, at 12 p.m. Central

Kim D. Coder, PhD, Warnell School of Forestry and Natural Resources, University of Georgia

Trees grow with, and adjust to, large lateral and vertical loads caused by wind and gravity. Storms with strong winds and ice can push trees beyond their ability to reconfigure or fall back to reduce drag. Exceeding tree structural ice and wind load limits cause branch, root, and crown failures, or complete catastrophic loss of the tree. Wind loads greatly increase with small mile-per-hour velocity changes. Storm wind loads and ice storm issues, and how they impact trees, will be reviewed.

Fighting Microbes with Microbes to Protect Our Native Trees

Register Here

Tuesday, June 9, 2020, at 12 p.m. Central

Rachael Antwis, PhD, University of Salford

Ash dieback is a fungal disease sweeping through Europe, causing up to 95% loss of ash; one our most common tree species. In this seminar, Dr. Rachael Antwis will provide an overview of the disease, and how researchers are attempting to limit the loss of this important tree species. She will also discuss her recent research, funded by the TREE Fund’s Jack Kimmel International Grant, looking at how natural microbial communities in ash leaves may be important for regulating disease progression within the host.

Protecting trees from construction impacts

Tuesday, June 23, 2020 at 3 p.m. Central

Andrew Benson, PhD

With increased intensification in cities throughout the world, urban trees are often at risk of becoming damaged by construction impacts, such as utility trenching or pavement / sidewalk repair. If the damage is severe and a tree loses a lot of its roots, the consequences may result in tree failure, or tree removal due to subsequent poor health. In this presentation, we will look at some of the reasons why urban trees become damaged during construction and some of the more suitable methods available to prevent or limit that damage occurring. We’ll also look at some recent research which aims to improve what we know about the consequences of construction damage effects, and hopefully provide some useful tools to practitioners who work with roots on a regular basis.
