What are Invasive Species?

An invasive species is defined as an organism (plant, animal, fungus, or bacterium) that is not native and has negative effects on our economy, our environment, or our health. Not all introduced species are invasive.
Invasive plants and animals are the second greatest threat to biodiversity after habitat loss.
There are 154 introduced plant species in Yukon. Only 20 are considered invasive.
In other North American jurisdictions many invasive plants are responsible for habitat damage, loss of subsistence resources, and economic loss.
The economics of controlling invasive species damage can be considerable. Just looking at 16 species for which published information is available, a conservative estimate shows that in Canada we spend between $13.3 and $34.5 billion per year.
Yukoners are in the enviable position of preventing plant infestations before they become so widespread that control is costly and eradication impossible.
Everyone can help reduce the spread of those species already established.
