Lake Buchanan is a seasonal wetland comprised of saline flats, brackish water lakes, freshwater swamps, samphire associations, and sandy beaches supporting a Grevillea and Acacia woodland. This swamp is an important breeding site for a range of waterbirds. Lake Galilee has a similar range of habitats to Lake Buchanan but is less salty. It is reported to have large numbers of breeding waterbirds at times.
