Each provincial park was chosen to be protected for specific and significant reasons. MacGregor Point is classified as a "Natural Environment" park due to its natural beauty and the importance of the ecosystems within the park boundaries.
What makes MacGregor Point unique:
The Huron Fringe
From Sarnia to Tobermory, as series of glacial lake shorelines collectively creates a unique ecosystem known as the Huron Fringe. Glacial lakes Algonquin, Nipissing, and eventually Huron were formed after the last ice age 10,000 years ago. The Algonquin shoreline forms a tall hill you travel down after turning off Highway 21 to enter the park; the Nipissing shoreline can be climbed by stairs while hiking the aptly named Lake Ridge Trail, and the Huron shoreline is visible from the Visitor Centre.
The park protects several significant wetlands, which provide habitat for many species including the endangered Spotted Turtle. As water travels toward Lake Huron, its path is blocked by the ancient shorelines of the Huron Fringe, resulting in pools of water that form wetlands. A good example of this process is the 'Frog Pond' (or Vernal Pool) at the end of the boradwalk in front of the Visitor Centre. The gravel ridge on the lake side of the pond prevents spring runoff from draining into the lake, creating a small wetland that provides the perfect environment for unique species like the carnivorous round-leaved sundew plant.
Old Shore Road
Early European settlers built the only road in the area shortly after arriving by boat from Lake Huron. Many settlers would walk to Goderich from Southampton one day with a bag of wheat, and return the next day with a bag of flour. Part of this road now makes up Old Shore Road trail, following closely to the shoreline for 6km in the park.
