It is identified as a provincially significant wetland and an Area of Natural and Scientific Interest by the Government of Ontario. It is also classified as a protected area by the International Union for Conservation of Nature.
This 60-hectare natural environment is a complex of wetlands along the Ottawa River, the majority of which is made up of deciduous swamp forest. The driest part, to the west, contains a mature forest stand which is made up predominantly of white, red and burr oak, as well as white pine.
Mud Lake is a habitat for a wide diversity of animal species. Located within the Lac Deschênes–Ottawa River Important Bird Area and in a major migratory corridor, it serves as an important environment for bird conservation, and is recognized as one of the most popular urban sites for birdwatching in Canada.

To protect Mud Lake’s natural habitat, the NCC has launched a vegetation management project. We are undertaking manual and mechanical work, which began in fall 2015 and will continue to fall 2017, to control invasive non-native plant species. This work will allow native plant species to become re-established, and will help preserve the ecological integrity of the natural environment.
