New Online Resources

Friends of Second Marsh staff are sharing their knowledge of the Oshawa Second Marsh online. At this time of year, there's a lot to see and hear. Learn about Oshawa Second Marsh Animals and Plants through our educational and informative posters. These will be available under the Programs & Events Heading - Online Engagement. We will also be preparing videos to highlight some of the interesting stops on our hikes. These are coming soon! Please watch our social media and website for more information. Check out our first poster, it's about the White-tailed Deer.

The SECOND MARSH WILDLIFE AREA is a 123 ha coastal wetland located in the southeast portion of Oshawa, (Regional Municipality of Durham), Ontario, Canada.  The combination of Second Marsh with the adjacent areas of McLaughlin Bay Wildlife Reserve and Darlington Provincial Park represents nearly 400 hectares, one of the largest publicly accessible waterfront spaces available in the Greater Toronto Area (GTA).  It is located on the north shore of Lake Ontario in a major urban center, and is unique in being the largest remaining wetland in the GTA.
The Second Marsh Wildlife Area is host to marsh, swamp, wet meadows, a barrier beach and woodlot habitats.  Within the Marsh, you will find sedges and cattails as well as thickets and open water.  At the north end of the Marsh, a swamp and wet forest known as the Ghost Road Bush provides additional food and cover for certain wildlife.  Together, with wet meadows and the surrounding uplands, this dynamic ecosystem supports a rich and diverse wildlife community.  These habitats provide food and cover for over 380 plant species, 305 bird species, numerous species of mammals, reptiles, amphibians, fish and hundreds of species of insects.
Second Marsh is not only the largest remaining urban wetland in the GTA but the largest between the Niagara Peninsula and Presqu’ile as well.
