Become a Forest Health Volunteer!

Learn how to monitor tree health in your community by attending BioForest’s training workshop!  This training session will teach you how to detect insect and disease problems in urban forests.  To R.S.V.P., email volunteers@bioforest.ca

Oak wilt detection will be featured in the forest health volunteer training session. 
To learn more about oak wilt, visit the species profile.

If you see signs and symptoms of oak wilt, please report the sighting to EDDMapS Ontario and the Canadian Food Inspection Agency

Be aware of hemlock woolly adelgid!

Hemlock woolly adelgid (HWA) is native to Asia, and was first detected in eastern North America in the 1950’s. This invader attacks native hemlock species, which are commonly found in Ontario forests and urban spaces.

Look for white, cotton-like or woolly masses forming on the base of hemlock needles.

To learn more about the hemlock woolly adelgid, visit the species profile.

If you see signs and symptoms of HWA in Ontario, please report the sighting to the CFIA or EDDMapS Ontario.


Be aware of the Asian Longhorned Beetle! 

Asian Longhorned Beetle (ALB) is an invasive beetle native to Asia was introduced to North America in the early 1990s. It is especially concerning for Canada as it threatens our hardwood trees which provide numerous ecological and economic benefits. To learn more, visit the ALB species profile

If you see ALB in Ontario, please report the sighting.

The Canadian Food Inspection Agency regulates ALB in parts of Ontario. Learn more here


July 15, 2016 - On June 27, 2016, the presence of European cherry fruit fly (Rhagoletis cerasi) was confirmed in an urban park in Mississauga, Ontario. This marks the first confirmed detection of this potentially destructive invasive insect in North America. Read more here. 



June 30 2016 - Emerald ash borer (EAB) has been confirmed in Thunder Bay Ontario. This marks the first time the insect has been detected outside of the regulated area in the province. Effective immediately, the CFIA is restricting movement of all ash material such as logs, branches, and wood chips, as well as all species of firewood from the affected site.

Emerald ash borer is a highly destructive forest pest that has already killed millions of ash trees in North America. To learn more about this insect, visit the Forest Invasives Emerald Ash Borer Species Profile 

Help stop the spread of this invasive insect. Don’t move firewood – buy it where you burn it.

Beech Bark Disease Workshop - This September, the Invasive Species Centre hosted a professionals’ workshop in Huntsville Ontario to highlight beech bark disease (BBD). Discussions and presentations held at this workshop will contribute to an Ontario focused beech bark disease best management practices (BMP) guide, currently under development.  This workshop initiated collaboration between international experts on beech bark disease from academia, industry, and government. Participants from Ontario, Quebec, New York, and Michigan were in attendance.

August 9, 2015 - Parasitoid wasps released to fight emerald ash borer. After an extensive environment assessment and review process, two species of exotic parasitoids are being released in Ontario and Quebec for classical biological control of emerald ash borer. These include a larval parasitoid (Tetrastichus planipennisi), and an egg parasitoid (Oobius agrili). This work is partially funded by the Invasive Species CentreRead more here


May 28, 2015 - Peterborough residents' ash trees get help from Canada pilot project. Tree Canada has launched an initiative in Peterborough, Ontario to assist in the treatment of private homeowners’ ash trees in conjunction with the city of Peterborough’s treatment plan for their public trees. This will significantly reduce the cost to treat ash trees by as much as 50%. For more information on the program, click here. 

If you live in Peterborough and would like to be a part of the program, download the application form here

October 10, 2014 - Is the Emerald Ash Borer Switching Hosts? Recent research suggests that the emerald ash borer, an invasive forest pest destroying millions of ash trees across North America, is now attacking a new species of tree; the white Fringetree (Chionanthus virginicus). Professor Don Cipollini of Wright State University in Ohio discusses the potential impacts of this discovery. Read more.  


October 15, 2014 - Genomic Tools for Invasive Species. Natural Resources Canada, with Genome British Columbia, is developing exciting ways to implement genomic tools into invasive species detection and identification. The ability to rapidly and accurately identify an invasive pest, whether as an adult or an egg, a fragment or a full specimen, will allow for early detection and rapid response to control and eradicate an invasive pest before it has a chance to become established in Canada. This innovative technology is currently being developed for identification of Asian gypsy moth and sudden oak death in British Columbia. Read more.
