Managing Invasive species

Parks Canada works with many groups to protect threatened ecosystems and wildlife from invasive alien species (IAS). Together, we use leading-edge techniques to prevent and control them. We also restore areas damaged by IAS and help native species recover. And you too can help.

What are invasive alien species?

Invasive species are plants, animals, insects and pathogens that share several key traits:

• they are non-native to the ecosystem where they've been introduced
• they can establish themselves in natural or semi-natural ecosystems
• they often outcompete native species for resources like food and habitat
• they have the potential to alter ecosystem balance and dramatically decrease biodiversity
• their introduction can cause significant harm to the economy, environment, or human health

What's the problem

Invading plants, animals and diseases threaten: 

•  the valued natural environment
•  the economy, costing billions of dollars to many industries
•  social and cultural practices and human health.

How you can help

Invasive alien species are difficult to nearly impossible to eradicate once they are introduced.

You can help stop the spread of invasive alien species during a visit by taking the following actions:

• Stay on marked trails
• Keep pets on leashes
• Play, Clean, GO
• Clean, Drain, Dry
• No natural fishing bait
• Do not move firewood
