Ottawa – Every August, the Canadian Food Inspection Agency (CFIA) observes Tree Check Month as a reminder of the importance of protecting our precious plants and trees from invasive pests. Throughout this month, Canadians are encouraged to inspect backyards, gardens, local parks and even vehicles, for any unwelcome pests.
Plant health is essential to Canada’s economic prosperity and it is directly linked to the health of people, animals and the environment. The introduction and spread of invasive species could have devastating impacts on human and animal health and Canada’s forests, agriculture, environment and economy.
Many plant pests and diseases affect the health of plants and trees all across Canada. These pests are most often introduced and spread throughout via human activity. Oak Wilt was found in Canada for the first time in June. This dangerous disease poses a serious threat to oak trees, and if it spreads, it could have a major impact on our forests. Another invasive species to watch out for is the Spotted Lanternfly, which has not yet reached Canada, but is present in the United States near the Canadian border. This pest can be particularly harmful to vineyards and orchards all across the country.
Invasive species and diseases can cause irreversible and widespread damage to our environment, agriculture, and economy. There are many ways Canadians can help protect our forests and plants from invasive species and disease:
- Not all pests are equally spread across Canada. Learn about the invasive insects and plant diseases that could be found in your community on the CFIA’s website.
- Inspect the trees in your yard and their surroundings, and look for unusual or sudden changes in the tree’s health, such as discoloration of leaves, cracks in the bark, presence of insect holes, tunnels beneath peeled bark, etc. Start your inspection at the roots, move up the trunk and along the branches, looking for noticeable insect populations and signs of feeding activity on the leaves.
- Report suspected invasive species or plant disease to the CFIA. Timely reporting allows CFIA inspectors to investigate the source and take preventive measures against further spread. Early detection is the best way to protect our trees and plants.
- Prevent the spread of invasive species and pests, as they can travel in many different ways. Do your part to stop their spread by checking for egg masses and insects on your vehicle, RV, trailer, boat, etc. before going on and returning from a trip.
- Another way to prevent the spread of pests: don’t move firewood. Pests and their eggs can be hiding under the bark. Buy local and burn local instead.
Anyone can participate in Tree Check Month, even kids. Check out our plant health hero activity book where kids can learn about the importance of plant health within their own community and Canada, the numerous threats to plant health like invasive species, and how they can help to protect plant life. Canadians of all ages can play a role in keeping our plants and trees healthy for a better future.
