Ontario Nature has recently expanded the Gananoque Lake Nature Reserve by adding 23.74 hectares (58 acres). This expansion enhances the reserve’s ecological footprint and contributes significantly to the conservation efforts within the Frontenac Arch, recognized globally for its biodiversity.

What is Special About the Reserve
The Gananoque Lake Nature Reserve is integral to the conservation strategy of the Frontenac Arch, a UNESCO World Biosphere Reserve known for its unique geological and ecological characteristics.
- The reserve is part of a crucial natural corridor that connects distant wildlife populations between New York’s Adirondack State Park and Ontario’s Algonquin Park.
- It supports a high level of biodiversity and is a priority area for habitat protection, helping species at the northern and southern edges of their ranges adapt to climate changes.
- Ontario Nature’s initiative to protect this area is supported by government and private funds, including the Natural Heritage Conservation Program.
What is in the Newly Acquired Property
- The newly acquired area includes diverse habitats such as deciduous and mixed forests, treed swamps, and thicket swamps.
- Open rock barren outcrops, wetlands, and extensive shoreline along Gananoque Lake have also been incorporated.
- This acquisition plays a critical role in maintaining habitat connectivity within the Algonquin to Adirondack corridor.
Wildlife in the Reserve
The Gananoque Lake Nature Reserve is home to an array of wildlife, benefiting from the diverse ecosystems within its expanded boundaries.
- The forests are populated with mature hickory, oak, elm, and maple trees, providing habitat for birds like the cerulean warbler, eastern wood-pewee, and scarlet tanager.
- The property’s wetlands are vital for amphibians and reptiles, including species at risk such as the western chorus frog and gray ratsnake.
- Over 25 at-risk species have been documented in the area, thriving in habitats ranging from moist forest floors to lush submerged vegetation along the lake.
Can You Visit the Reserve
Currently, public access to the Gananoque Lake Nature Reserve is limited, as the property does not have developed trails for land-based exploration.
- Visitors are encouraged to experience the natural beauty of the reserve from the water.
- Canoeing, kayaking, or boating along Gananoque Lake offers unique views and opportunities to observe the diverse aquatic and shoreline habitats.
- While there are no land trails, the reserve’s waterways provide an accessible route for viewing its ecological features and wildlife.
