A biodiverse refuge within the ecologically significant wildlife corridor from the Adirondack Mountains to Algonquin.

The Gananoque Lake Nature Reserve is a remarkable property that officially became our 26th nature reserve in February of 2020. The property is located in eastern Ontario within the Frontenac Arch – a geological wonder that supports some of Canada’s richest biodiversity and is home to many species at risk. This landform is part of a natural habitat corridor that allows wildlife to migrate between the mountains of Adirondack State Park in New York and Algonquin Park in Ontario, some 400 kilometres away.

For these reasons and many more, the Frontenac Arch is a high-priority area for habitat protection. Located a short distance from our Lost Bay Nature Reserve, this property is Ontario Nature’s second in the Frontenac Arch.

Ontario Nature was able to permanently protect this 147-hectare (358-acre) property thanks to the generous contributions from our members and supporters. Thanks to you, the rich biological diversity of this property’s upland hardwood forest and 173 acres of provincially-significant wetland will be protected forever.

Plants and Animals

Large towering hickory, oak, elm and maple trees fill the canopy of this mature hardwood forest. The songs of cerulean warbler, eastern wood-pewee and scarlet tanager can be heard resounding through the trees. The endangered butternut flourish on the property, taking advantage of moist, rich and well-drained soils.

Wetlands are located throughout the property and along Gananoque Lake. They are dominated by cattails, pickerel weed and water lilies. Lush submergent vegetation fills the lake, creating habitat for fish, frogs and turtles that can be easily spotted while canoeing through the clear and calm waters.

More than 25 species at risk have been recorded in the immediate area. These include the cerulean warbler which lives and breeds in mature hardwood forests, western chorus frog and several at- risk reptiles including the gray ratsnake.

“The forest has impressive specimens of red and white oak, as well as distinctly southern components such as shagbark hickory and American bladdernut. The open-water marsh features many species of submerged aquatic plants, from false mermaidweed to wild rice.”
