Swishwash Island is a private nature sanctuary owned by the Nature Conservancy of Canada. It is a small beacon of biodiversity located in the middle arm of the Fraser River Estuary which is one of the most productive estuaries in the world.
Swishwash Island was donated to the Nature Conservancy of Canada by BC Packers Ltd. in 1999. Located next to the Vancouver International Airport, the island serves as a small yet important sanctuary for fish, birds and wildlife in an otherwise highly developed area.
