Lac Deschenes is near one of the largest urban areas in the country, medicine ask and faces many pressures. You can do your part to help keep Lac Deschenes clean, view healthy and accessible for wildlife, pilule for people, for generations. Pressures on the site include:

•    water withdrawals for human consumption, municipal and industrial uses
•    direct urban run-off into the river
•    traffic related to recreational boating and sailing
•    overflow drainage from storm and sanitary sewers
•    residential and/or industrial shoreline development
•    shoreline erosion

Much of the IBA on the Ontario side of the river is made up of National Capital Commission lands, which are actively managed. Land ownership on the Gatineau-Aylmer side of the river is more varied and includes private residential and commercial property, as well as lands managed by the NCC and the Ville de Gatineau. Because the IBA is mostly aquatic and spans two provinces, the two provincial governments and the federal government all have a responsibility to manage and protect the site and its wildlife.

Nature Canada, alongside the Ottawa Field-Naturalists Club, the Outaouais Birding Club and key stakeholders are developing a Conservation Plan for the Lac Dechênes IBA, which will help to identify the state of the IBA, the pressures it is facing and the collective responses that are required to address those pressures. This plan will provide a roadmap for how stakeholders, including you, can work to protect the IBA from negative pressures.

You can walk, bike, hike, run, swim and even canoe/kayak in various parts of Lac Deschênes! And you can do all of this right in the heart of one of the city’s most important wildlife habitats! Lots of birdwatchers flock to the Lac Deschênes area during the spring and the fall to see which feathered friends are passing through, and it’s a great place for everyone to visit year-round.

The Ottawa Field-Naturalists Club, the Outaouais Birding Club, the Innis Point Bird Observatory and the Macoun Field Club  all conduct events and activities regularly at and around the Lac Deschênes area. Nature Canada  is joining in on the action at the National Capital Region’s only Important Bird Area, too! Check out our list of events  and activities to find out more.

Why is this place so important?

Lac Deschênes is recognized as a globally significant Important Bird Area (IBA) because it is one of the larger bodies of water in this region that waterbirds depend on  during their spring and fall migrations. And it’s found right in the heart of the National Capital Region!

What is a ‘waterbird’? This includes species of loons, grebes, pelicans, cormorants, bitterns, egrets, herons, ibises, rails, coots, gulls, terns, and skimmers. By some definitions the list is even longer.

Some of the birds that stop on Lac Deschênes fly all the way from South America to the Arctic two times each year, while most of them are flying from parts of the southern United States and the eastern seaboard to parts of northern Québec and Ontario. Whatever the case, Lac Deschênes is a great spot to take a rest and re-fuel during a long flight!

What kind of wildlife is found there?

You’ll find lots of wildlife at Lac Deschênes – not just Canada Geese! During the spring and fall you can see and hear songbirds like Warblers and Vireos moving through the region, and huge groups of Ring-billed gulls, Herring and Great Black-backed gulls, and tens of thousands of waterbird species. August is ideal for watching Great Egrets on the move southward, and you may even spot some shorebirds moving through and feeding on exposed mud flats (when the river is low).

Numerous other waterbirds stop at the lake during their fall migration, including the more common dabbling and diving ducks such as Scoters and Common Golden-eye. Arctic Terns are seen sometimes in spring along with larger numbers of Common Terns. Only moderate numbers of shorebirds are seen along the shores of Lac Deschênes; particularly along the muddier parts of the shoreline at Shirley’s Bay and Andrew Hayden Park, both on the southern side of the lake in Ottawa.

And you’ll see other critters, too! The Lac Deschênes area is home to amphibians, reptiles, aquatic insects, mammals. and numerous freshwater fish. The IBA is also home to a wide variety of plant species from small aquatic plants to towering trees. The Government of Québec has identified significant habitats for at least two provincially at-risk plant species on islands in the Ottawa River just beyond the Lac Deschênes IBA.
