As noted by the USACE (1999), the proposed restoration effort at the Sedge Islands will likely have a positive effect both on federal listed threatened and/or endangered species of birds (e.g., the American peregrine falcon, Falco peregrinus anatum; osprey, Pondion haliaetus; piping plover, Charadrius melodus; roseate tern, Sterna dougallii; and migratory bald eagle, Haliaeetus leucocephalus
), and state protected species of birds (e.g., the black skimmer, Rynchops niger, least tern, Sterna antillarum; black rail, Laterallus jamaicensis; and short-eared owl, Asiofiammeus) by not only preserving existing habitat but also creating additional nesting and foraging habitat.

The Strait of Georgia has a rapidly expanding human population (Johannessen and McCarter 2010), and nesting cormorants face threats from pollution (contaminants and oil), declines in prey fish (from fisheries, habitat changes, and climate change), and disturbance on nesting colonies (from both people and Bald Eagles Haliaeetus leucocephalus
