Resources |  Invasive Species

Invasive species are plant or animal species that have been introduced from another part of the world into our native, or endemic, ecosystem. Invasives are particularly aggressive species that can displace and overtake native populations, sometimes having a devastating effect on native ecosystems.


Scientists estimate that there are more than one hundred and seventy (170) non-indigenous fish, invertebrates, plants algae, protozoa and parasites that have entered the Great Lakes system, some of these responsible for some astounding changes to the Great Lakes ecosystem.


We have identified some key invasive species that are having a serious impact on Lake Huron's ecology. Understanding their effects on the ecosystem is important to recognizing how they are affecting the environment, and, where possible, making efforts to minimize their damaging affects.

Phragmites australis (European Common Reed)

Garlic Mustard

Round Goby

Zebra Mussels

Giant Hogweed
