Infographic for Invasive Species

We encourage you to learn more about invasive species in Canada, and what you can to do to help control the spread.

What is an Invasive Species?

An invasive species is a non-native, living organism (plant, animal, or disease) causing a negative impact to ecosystems, the economy, or even human health. The impact of invasive species is estimated to cost $30 billion annually, in Canada. To learn how you can help prevent the spread of invasive species, visit

Take action and report invasive species. The more eyes on the ground, the earlier we can detect and manage invasive species before an infestation gets out of hand! To report sighting visit – I Spy and Identify Invasives

Prevent the Release of Species

May 19, 2023 is Endangered Species Day. Did you know that your pet can be an invasive species and can impact our native and at-risk species? Ensure your pets are kept safe and re-homed responsibly. Escaped or released animals, like pigs, can impact agriculture, damage property, and spread disease to livestock. Never release pets into the wild. Take the pledge at

Horticulture and Invasive-free Gardening

No one likes a weedy garden. In Canada, 40% of non-native vascular plants are considered weedy or invasive species. Invasive plants can outcompete native plants for nutrients, water, and space in your garden, and other natural spaces. For a Plant Wise garden make sure to, buy locally grown plants, plant only non-invasive and native plant species, and know how each plant grows. Support your pollinator friends this World Bee Day by planting wise and grow non-invasive garden species, more information at
