Species at Risk

species at risk species at risk fact sheet

Our health and quality of life depends on biodiversity – a mix of wild plants, animals and habitats. We are fortunate to live in a province of rich biodiversity and our job is to ensure there is enough suitable, healthy habitat available so that Ontario’s plants and animals can thrive and grow. 

Conservation Authorities, landowners and community groups are working together to improve, restore and secure natural habitat for species at risk.

The following fact sheets show a few examples of actions to help rehabilitate and enhance habitats for species at risk. Tree planting, shoreline rehabilitation and naturalization projects have their benefits for the landowner and the environment. Learn more and get involved!

Monarch butterfly (Danaus plexippus) is of “special concern” in Ontario and Canada. This means it is a native species that is sensitive to human activities or natural events. Declines in the Ontario populations of monarchs are related to logging and disturbance of the over-wintering sites in Mexico and use of pesticides and herbicides, as well as loss of habitat in Ontario. Monarchs are common where there is open land, roadsides and in city gardens and parks. Canada and Mexico have made a joint declaration to nominate sites within both countries as part of an International Network of Monarch Butterfly Reserves. Three areas along the north shore of lakes Ontario and Erie have been designated as reserves — Long Point National Wildlife Area, Point Pelee National Park, and the Prince Edward Point National Wildlife Area. What can you do? Plant a garden with native wildflowers as a nectar source, including milkweed as a food source for its caterpillar.
