Simulated changes in extent of Georgian Bay low-marsh habitat under multiple lake levels
The extent of coastal wetlands in Georgian Bay is controlled primarily by water level of Lake Huron, which directly affects the amount of critical habitat available for fish and wildlife communities. Lake-levels have historically fluctuated by nearly 2 m and that range could… Read More
Status of Georgian Bay wetlands
There are more than 3700 coastal wetlands along the eastern coast of Georgian Bay. They are unique among other coastal wetlands in the basin of the Laurentian Great Lakes, being some of the most pristine (Chow-Fraser 2006; Cvetkovic and Chow-Fraser 2011), and receive minimal… Read More
Connecting Coastal Marshes Using Movements of Resident and Migratory Fishes
In the Laurentian Great Lakes, diurnal migration of fishes into and out of coastal wetlands is well documented, but movement among wetlands is more poorly understood despite important conservation implications. We assessed movements of typically resident species using mark… Read More
Thirty-year update: Changes in biological characteristics of degraded muskellunge nursery habitat in southern Georgian Bay, Lake Huron, Canada
Aquatic vegetation is a critical component of nursery habitat for young-of-the-year (YOY) muskellunge. The trophy status of the muskellunge fishery in southeastern Georgian Bay owes its reputation to the widespread distribution of aquatic vegetation in coastal marshes of this… Read More
Impacts of declining water levels on the quantity of fish habitat in coastal wetlands of eastern Georgian Bay, Lake Huron
There are 3,700 coastal wetlands along 4,500 km of eastern Georgian Bay (GB), providing critical spawning and nursery habitat for migratory fish of Lake Huron. Sustained low water levels since 1999 have led to the loss of fish habitat due to severance of wetlands from GB. We… Read More
