The Importance of South Shore’s Coastal Wetlands

In recognition of World Wetlands Day — February 2

By Cheryl Anderson (2026)

Every year on February 2, communities around the world celebrate World Wetlands Day, a reminder of how essential wetlands are to healthy ecosystems and healthy communities. Here in the South Shore of Prince Edward County, we are lucky to have several important coastal wetlands worth celebrating and protecting.

These wetlands include areas in the National Wildlife Area, Big Sand Bay, Gull Pond at Charwell Point in Monarch Point Conservation Reserve, and the wetland at the end of Wellbanks Road. Each one plays a key role in keeping our shoreline resilient.

Coastal wetlands act like natural sponges. When Lake Ontario’s water levels rise, wetlands absorb the extra water so it doesn’t end up flooding homes and roads. As lake levels rise and fall, the wetlands are refreshed, creating new habitat for birds, fish, turtles, frogs, and the trees and plants that grow in them.

Because wetlands are rich in nutrients, they support an incredible amount of life. Many reptile and amphibian species at risk depend on PEC wetlands, including most of Ontario’s turtle species and the Western Chorus Frog. In Hillier, Slab Creek wetland has become well known for nesting Great Egrets and Great Blue Herons. These birds aren’t at risk, but their presence shows just how vibrant a natural wetland can be.

Wetlands are often called “the kidneys of nature” because they filter pollution from water. In some places, wetlands are even used as the final treatment stage for wastewater.

In the South Shore, Ducks Unlimited has created two impoundments in Monarch Point Conservation Reserve. These managed wetlands support species of all taxa including River Otters, Northern Harriers and White Ladies’-tresses Orchids. They also provide recreational opportunities for local duck hunters, hikers and birdwatchers.

Unfortunately, wetland protection in Ontario has weakened in recent years. This makes it even more important for naturalists, scientists, and community members to speak up when development threatens these sensitive areas.

World Wetlands Day is a perfect moment to remember that protecting wetlands means protecting wildlife, clean water, and the long-term health of our shoreline.
