Zebra Mussels, Invasive Species

Invasive Species

Invasive species are plants, animals, or other organisms growing and living outside their country or region of origin. 

They commonly out-compete or even replace native organisms since invasive species are away from their predators, which gives them an advantage. Populations of native species are kept in check by native predators, competitors, or diseases. 

Common species include common carp, rusty crayfish, spiny water flea, and purple loosestrife. One purple loosestrife plant can produce over 300,000 seeds and choke out native plants. Fish, birds, and animals rely on native plants to feed, seek shelter, and rear their young. 

How do Invasive Species Affect Water?

Invasive species contribute to extinction and biodiversity loss. Prevention, early detection, and fast response are critical for saving habitats.  

Invasive species have been introduced in the Lake Winnipeg watershed. Humans are most often directly tied to bringing a species to a new region, intentionally or unintentionally. These species can come from bait buckets, fish tanks, and non-native plants.
