Second only to Lake St. Clair as the most important migration staging area for waterfowl in Ontario south of James Bay. Long Point is one of the last resting and feeding areas for southbound birds before crossing Lake Erie, and one of the first for northbound birds. As many as 30,000 tundra swans pass through the marshes in the spring, as well as a significant portion of the North American population of canvasback and redhead ducks concentrate here during spring and fall migration. A great variety of songbirds can also be found here during migration. Long Point is also important to fish as a spawning and feeding area.
Species found here include smallmouth bass, largemouth bass, pike, smelt and yellow perch.
Six species of turtles nest here yearly, including three the rare spotted turtle, and eastern spiny soft-shelled turtle. Monarch butterflies concentrate at Long Point in September during their long migration to Mexico. No facilities available. Boat access only to designated areas.
