Encouraging all Canadians to "leaf" a mark during Tree Check Month

Canadian Food Inspection Agency

The Canadian Food Inspection Agency (CFIA) is proud to mark Tree Check Month this August. This annual campaign urges Canadians to thoroughly inspect trees and plants in their backyards, gardens, parks, and vehicles for invasive pests.

Many insects, diseases, and pests can cause extensive and lasting harm to our environment, agriculture, and economy. They often spread through human actions like transporting firewood and vehicle travel between regions. The emerald ash borer has been particularly devastating to ash trees across Canada, leading to extensive ecological and economic losses. Likewise, spongy moth poses a significant threat by stripping various hardwood species of their foliage.

The most effective way to manage these harmful invaders is to prevent their spread before they cause irreparable damage.

You can take several steps to protect our forests and other plants from these threats:

• Learn what to be on the look out for in your community! Canada is vast with many different climates so not all pests are evenly distributed across the country. Visit the CFIA's website to learn about invasive insects and plant diseases specific to your community.
• Look for unusual or sudden changes in tree health, such as leaf discoloration, bark cracks, holes, and tunnels beneath peeled bark.
• Inspect! Before and after trips, inspect your vehicle, RV, trailer, boat, and other outdoor equipment for insects (egg masses as well as adults), seeds, plant debris and soil. This helps prevent the accidental transport of pests to new areas.
• Report! If you suspect the presence of invasive pests, report them to the CFIA immediately so that our inspectors can take action and prevent further spread.
• Prevent spread! Don't move firewood. Insects and their eggs can hide under the bark. Instead, purchase firewood locally and burn it where you buy it.

You can also join the CFIA's Plant Health Hero challenge. Complete the activity book, invite friends, family, and neighbours to explore the outdoors, inspect their trees, and share photos on social media during the month of August using #TreeCheckMonth. Help us spread awareness!

Healthy plants contribute to clean air, water, and soil, support wildlife habitats, and provide essential resources for the agriculture and forestry industries. By working together to safeguard our pristine green spaces, Canadians can make a positive impact on the health of people, animals, the environment, and the economy.
