Forest invasive species

There are many ways that FIS are spread both naturally and by human activity. People can unknowingly move invasive species hundreds of kilometres in a single day.

Firewood is the most significant method of spreading FIS. Insects and diseases can be hidden in, on, or under the bark of firewood, or even deep within the wood.

Other key ways that humans spread FIS include the use and transport of: 

• cargo and containers
• camping gear and outdoor equipment
• patio furniture
• trucks and cars
• plants and plant materials (including nursery plants, logs, and firewood)

FIS can badly harm the forest environment, the economy and society. In Bruce Peninsula National Park, Fathom Five National Marie Park and the surrounding area, this could mean: 

• disrupting our enjoyment of forested areas, like trails, campgrounds, and shorelines
• harming the park's unique black bears that rely on tree nuts and seeds for food
• changing the environment, including soil and water quality
• increasing the risk and intensity of wildfires and changing fire patterns
• loss and reduction of species, including those of conservation concern
• damaging valuable timber resources and increasing forest management costs
• damaging culturally important species like Black Ash trees.
• creating safety risks for visitors, staff, and buildings
• creating hazardous trees that are expensive to remove
