The 627 ha nature reserve located in the headwaters of Otter Creek of the Salmon River system, protects one of the largest examples of open and treed fen in southeastern Ontario. Fens, which are rare in southern Ontario, are botanically rich wetlands found mostly in large shallow depressions in the landscape. In the middle of the reserve is Mud Lake, a shallow water body, surrounded by 19 different natural habitats. The nature reserve protects significant wildlife species, including the Olive Hairstreak Butterfly and Cooperís Hawk.
