TREE Fund Webinars

TREE Fund webinars bring you the latest in tree research, directly from the scientists themselves. These one-hour programs are free and offer 1 CEU credit from ISA, SAF or NALP. Pre-registration is highly recommended; in doing so, you’ll receive a reminder email the day before the program.



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


Upcoming Webinar

Emerald Ash Borer: Strategies for Conserving Ash in the Urban Forest

Dr. Dan Herms, VP of Research and Development, The Davey Tree Expert Company

November 28 at 12:00 p.m. Mountain (please note date change) – translate to your time zone

Learn about the research that provides the scientific basis for emerald ash borer (EAB) management and conservation of ash in urban environments. Dr. Herms will walk you through the results of multiyear insecticide trials with soil applied, trunk injected, and bark applied systemic insecticides, which show that protection of even very large caliper ash trees is a viable option to consider as part of an integrated management program for EAB. See how the EAB Cost Calculator and tree inventories can be used to integrate treatments with removal schedules to develop proactive, strategic management programs for ash and the EAB “death curve” in the urban forest. If you are a municipal forester, city manager, arborist, consulting arborist, researcher, extension specialist, landscape manager, property owner, or land manager, you don’t want to miss this program!

Dan Herms is Vice President of Research and Development for The Davey Tree Expert Company. Prior to joining Davey, Herms was a professor in the Department of Entomology at The Ohio State University (OSU) from 1997-2017. He received his B.S. in Landscape Horticulture from OSU in 1982, his M.S. in both Horticulture and Entomology, also from OSU in 1984, and a PhD from Michigan State University in Forest Entomology in 1991. His research and outreach programs have focused on the ecology and management of insect pests of trees in forests, urban forests, and ornamental landscapes.

We are grateful to Utah State University Forestry Extension for hosting this program.
