Ontario Nature’s most northern nature reserve is part of the Jocko Bay Provincially Significant Wetland and hosts several different wetland types including cedar swamp, thicket swamp, and both treed and shrub fens.

The entire property was logged before the Sault Field Naturalists purchased the property in 1968, but good stands of cedar have grown back on the property’s western section and its natural restoration process continues since becoming protected.

“Being the steward of an Ontario Nature property ‘locks you in’ and makes you feel bigger and better for being responsible, for the Planet really, but in your own little micro-environment.”

– David Euler, past president of Sault Field Naturalists

Plants and Animals

A number of northern orchid species can be found on the property, including dragon’s mouth, heartleaf twayblade and green adder’s-mouth. Rattlesnake plantain can be found on the drier ground of the wooded knoll.

Long-eared owls, northern harriers and red-shouldered hawk are some of the birds of prey that find shelter in this hidden gem.
