Site description Pigeon Island is located about 15 km south of Kingston in the eastern basin of Lake Ontario. It is flat, about 5 ha in size, dominated by limestone bedrock, and has a thin covering of soil and guano that supports grass and herbaceous plant communities. The only woody vegetation is a clump of dead lilac bushes near the centre of the island. A tall metal tower is present, which supports an automatic navigational light.
