Wetlands are invaluable ecosystems, for us humans as well as for the plants and animals that live there. In fact, countless species of plants and animals could not survive without these habitats. They are key parts of the water cycle, serving as our planet’s "kidneys". Canada is very fortunate in that a quarter of all the world’s wetlands are found right here.

Announcing the official opening of the marsh interpretation path. The pond next to the Tree House got a facelift in 2002! A variety of work was done, including deepening the marsh in spots so that aquatic plants could be added and altering the banks to provide a habitat for semi-aquatic plant species. Interpretation stations along the 400-metre path offer detailed information on wetland ecology and the plant and animal species in the marsh. Visitors will learn how to tell dragonflies from damselflies, diving beetles from water beetles, and more.

Marshes play an essential environmental role as enormous natural filters that help to purify water, much like human kidneys. Their diversity and productivity make them the richest of all ecosystems.

These semi-aquatic habitats also attract a wide variety of birds, small mammals and insects—they’re the perfect spot for nature lovers young and old to explore.

The Botanical Garden invites you to visit its new marsh, a tranquil, peaceful haven far from the hustle and bustle of the city.
