Welcome to the
Invasive Species Centre Webinar Series!
The Invasive Species Centre is collaborating with experts in the field of invasive species management, prevention, and monitoring to discuss different topics each month.

Emerald Ash Borer (EAB) is thought to have been introduced to North America more than two decades ago. Despite efforts by Canadian and American plant regulatory authorities, EAB has spread across much of eastern North America. The insect kills most ash tree species (Fraxinus sp.) and regulatory efforts impose costs on plant health protection agencies, forest industry, private landowners and municipalities. The benefits of regulation are of course intended to reduce mortality of ash caused by EAB and all the associated costs associated.
Oak wilt is a disease that kills oak trees and is caused by a fungus named Bretziella fagacearum. Though not currently found in Canada, our distribution models indicate that suitable climate conditions currently occur in southern Ontario for B. fagacearum and two of its main insect dispersal vectors, Colopterus truncatus and Carpophilus sayi. Under climate change, much of the oak range in eastern Canada is projected to become climatically suitable for these species within the next two decades.
Present Status and Update on the Management of Emerald Ash Borer in Canada
Emerald ash borer has been in Canada for nearly 20 years. Since its discovery it has spread from southwestern Ontario to Canada’s east coast and its prairie provinces. In that time significant progress has been made in the understanding of the insect’s biology, ecology and management, but there is still much work to do. This webinar, presented by Dr. Chris MacQuarrie from the Canadian Forest Service, Natural Resources Canada, will summarize some of the recent research on emerald ash borer in Canada and efforts to manage the damage the insect is still causing.
New Biological Control Agents for Management of Invasive Plants in Canada
This webinar reviews the research steps required to implement biological control programs for invasive plants in Canada with specific focus on new biological control agents for Phragmites, Knotweeds, Swallow-worts, and Garlic Mustard. Presented by Ian Jones and Michael McTavish, Smith Forest Health Lab University of Toronto and Agriculture & Agri-food Canada (ACCC).
Update on beech leaf disease
Beech leaf disease is a disease of beech trees caused by a parasitic nematode, Litylenchus crenatae ssp. Mccannii. It was first detected in Ontario in 2017 along the shores of Lake Erie. In this webinar, Ontario Ministry of Natural Resources and Forestry researcher Dr. Sharon Reed, speaks on the state of beech leaf disease in Ontario and provides an update on her research on this invasive tree disease.
Ontario invasive species enforcement update
This webinar gave an overview of some of the activities the Ontario Ministry of Natural Resources and Forestry enforcement staff have been undertaking on an annual basis to help prevent the introduction and spread of aquatic invasive species including promoting awareness of the rules and inspections to confirm whether the rules are being adhered to. This webinar was presented by Brenda Koenig, Provincial Enforcement Specialist for the Ministry of Natural Resources and Forestry.
Forest under attack: The history, dispersal and management of gypsy moth
Presented by David Dutkiewicz from the Invasive Species Centre and Taylor Scarr from the Natural Resources Canada – Canadian Forest Service, this webinar will focus on the history of European Gypsy Moth and its subsequent arrival into Ontario in the 1980s. It will also discuss the current affected areas throughout Canada, and the areas where gypsy moth has the potential to spread. Lastly, this webinar will examine best management options for gypsy moth and the measures landowners can take to help slow the spread and protect our forests.
Collaborating to restore coastal wetlands and watersheds through invasive Phragmites control
Join Nature Conservancy of Canada’s Invasive Species Program Director Eric Cleland to learn about Canada’s largest invasive Phragmites management program that employs innovative tools and techniques to combat the country’s worst wetland plant invader at Long Point, Ontario.
Spotted lanternfly: Impacts and research from the USA and perspectives from Ontario
Join Penn State Extension experts Heather Leach and Julie Urban for an overview of the spotted lanternfly and the impacts, management, and research happening in its invasive range in the U.S. Additionally, explore perspectives and outreach strategies of stakeholders and agencies in Ontario with Invasive Species Centre expert Mandy Ehnes.
Water soldier (Stratiotes aloides) eradication efforts in Ontario
For the past 8 years, the Water Soldier Working Group has worked collaboratively to monitor and control populations of water soldier in the Trent-Severn Waterway (TSW). This webinar will recap the efforts to eradicate water soldier from this national historic site through introduced policy, outreach, education, and management in the TSW and private ponds across Ontario. This webinar will be presented by Robert McGowan from the Ontario Federation of Anglers and Hunters.
Controlling the spread of European water chestnut and parrot feather
Join biologist Kyle Borrowman to learn about various control methods employed by Ducks Unlimited Canada to control and limit the spread of two invasive aquatic plants, European water chestnut and parrot feather, that threaten Ontario’s native plant biodiversity. Active management by Ducks Unlimited Canada helps reduce existing populations and protect Ontario’s environment, economy, and social well-being from further spread.
