Hello Junior Naturalists!
This week’s theme is lakes! There are different types of lake habitats, all of which are important to sustaining aquatic plant and animal diversity. Canada has the most lakes of any country in the world, and it’s important that we take good care of them.
Toronto was built on the shore of Lake Ontario, one of the Great Lakes. Industrialization and urbanization has unfortunately led to the degradation of Lake Ontario. The populations of some native species like Atlantic salmon, American eel and lake trout have decreased over the years. Non-native species like round goby, sea lamprey and zebra mussel have been introduced and become invasive!
Efforts are being made to restore natural habitats and wildlife populations in Lake Ontario through research and recovery action plans. For example, The City of Toronto, Waterfront Toronto and the Toronto and Region Conservation Authority are working to revitalize the mouth of the Don River. The goal is to provide better aquatic and terrestrial habitat, and reduce the risk of flooding.

If you’re looking for a challenge, play the Great Lakes Game that Vanessa made! Find a path for the yellow perch to get to safety (aquatic plants) or food (crayfish) without encountering its predators (great blue heron and walleye).

We got a lot of great contributions this past week! Check out the gallery below for some amazing nature photos – many of them are of beautiful Ontario forests!
As always, have a great week and send us more photos! Try to get out to a lake if you’re able to. 🙂
