Forest Invasives Spring 2015 Webinar Series

During April and May 2015, Forest Invasives hosted a 6-session webinar series to highlight some of the most threatening invasive species in the Great Lakes region, and the management approaches available. Please find a recording of the live sessions below. 

Webinar #1
An Introduction to Forest Invasives 

Presented by Dr. Taylor Scarr on April 2nd, 2015

Dr. Taylor Scarr provides an introduction to the threats from invasive species to forests and urban greenspace from an Ontario perspective. Learn about where invasive species come from, how they spread across the landscape, how they can impact our ecosystems, economy, and well-being, and what can be done to stop them.



Webinar #2
Emerald Ash Borer: Public Awareness and Proactive Management 
Presented by Paul Hambidge on April 9th, 2015

The lethal emerald ash borer (EAB) has become established across much of eastern North America, and continues to spread throughout the range of the ash tree. The city of Peterborough has taken a proactive approach to manage for EAB in the urban environment. In this webinar, Paul Hambidge, urban forest specialist, discusses Peterborough's innovative approach.

Webinar #3
Asian Longhorned Beetle: Risk and Response 

Presented by Dr. Dean Thompson on April 16th 2015

The Asian longhorned beetle (ALB) has been threatening the urban tree canopy near Toronto, Ontario. Originally detected in Canada in 2003, quick management response was able to control the spread of the ALB. By 2013, there had been no ALB detections in over 5 years and it was thought to be eradicated. Unfortunately, the ALB is starting to make a comeback. Hear about the options to manage this invasive insect, including the effectiveness of the TreeAzin insecticide on ALB.

Webinar #4
Hemlock Woolly Adelgid: A formidable pest we can manage

Presented by Dr. Mark Whitmore on April 23rd, 2015


Slowly spreading across the eastern U.S., the hemlock woolly adelgid (HWA) is on Ontario’s doorstop. Effective management and control strategies are available. Dr. Mark Whitmore, forest entomologist at Cornell University, discusses what is being done in the U.S. to stop the spread of HWA. 

Webinar #5
Invasive Forest Pathogens in Ontario

Presented by Dr. Richard Wilson on April 30th, 2015


Invasive pathogens can have lethal impacts on Canada’s forests. Dr. Richard Wilson, forest pathologist with the Ontario Ministry of Natural Resources and Forestry, discusses some of the worst offenders,including beech bark disease, white pine blister rust, oak wilt, and more. Discussions include descriptions of the management options available for each species.

Invasive Plants in Ontario

Presented by Rachel Gagnon on May 7th, 2015

Invasive plants can spread across the forest floor, choking out native species and altering ecosystem dynamics. In this presentation, Rachel Gagnon, coordinator with the Ontario Invasive Plant Council, discusses garlic mustard, dog-strangling vine, invasive honeysuckles, Japanese knotweed, and common buckthorn.
