Containing one of the most botanically rich segments of the 640-hectare Long Swamp, the 45-hectare (112-acre) Malcolm Kirk Nature Reserve flourishes at the base of the Saugeen Bruce Peninsula.

Long Swamp is a Provincially Significant Wetland and an Area of Natural and Scientific Interest (ANSI).

Ontario Nature purchased this biologically rich property in 1972 after it had been optioned by our former nature reserves committee member Malcolm Kirk.

Initially called Long Swamp Nature Reserve, the reserve was renamed in Kirk’s honour to recognize his tireless involvement in protecting natural areas.

The western portion of the reserve is an open, minerotrophic fen on a floating sedge mat that extends into a small lake on an adjacent property. Most of the eastern section is wooded, with the wettest part being a combination of sphagnum mats and black spruce stands.

One of the few fens of this type on the Saugeen Bruce Peninsula, the reserve is home to sheep laurel, pale laurel, leatherleaf and small cranberry. The woods support red maple, paper birch, yellow birch, white cedar, balsam fir and hemlock.
