The Marianne Girling Nature Reserve is situated in the headwaters of Cedar Creek and includes portions of the Cedar Creek Provincially Significant Wetland Complex. The area is home to species at risk such as barn swallow, Eastern foxsnake, monarch, and short-eared owl. While much of the landscape has been used for generations of farming, the Marianne Girling Nature Reserve is an uncommon naturalized gem that contains important wildlife habitat.
