Site description Île Bicquette is located along the south shore of the St. Lawrence estuary in Quebec, 7.7 km off Cap-à-l’Orignal (a spit of land that extends from Le Bic Provincial Park). The larger Île du Bic island lies one kilometre to the southeast. Île Bicquette is composed of shale, and is surrounded by two little grassy islets and several rocky reefs. A large lighthouse, surrounded by the keeper’s residence, is located on the western part of the main island. Approximately 75% of the island is covered by forests, with the dominant tree species being Balsam Fir. The forests have been described as dense and “over-mature” with little sign of regeneration in the sapling layer.
