Iona Island in Richmond, British Columbia, Canada was formerly an island, but is now a peninsula physically connected to Sea Island via a causeway and Ferguson Road. Iona is home to a primary sewage treatment plant (located in the middle), an animal refuge and a park (Iona Beach Regional Park). The Iona Sewage Plant is located near the centre of the island and has tours for the public. Iona Beach Regional Park also features a beach adjacent to wildlife from the nearby animal refuge. The park is managed by Metro Vancouver. Iona Island is located almost adjacent to the Vancouver International Airport. The park is mostly visited by birders, as the sewage ponds have attracted many rare shorebirds such as Spoon-billed Sandpiper, Great Knot, and Red-necked Stint.
