DECLARED a Ramsar site in 1990, Roebuck Bay, south of Broome, is of international importance for at least 20 species of migratory shorebirds, and an important site in the East Asian-Australasian Flyway.
Roebuck Bay is a tropical marine embayment with extensive and highly biologically diverse intertidal mudflats. Dugongs, Green turtles and Australian Snubfin dolphins (Orcaella heinsohni) regularly feed on the extensive seagrass meadows in Roebuck Bay, which is also a major nursery for marine fishes and crustaceans and supports an exceptionally high diversity of benthic invertebrates (est. between 300 – 500 species), placing it amongst the most diverse mudflats in the world according to the Netherlands Institute. Indeed, Roebuck Bay’s tidal range is so large, it exposes a staggering 160 km² of mudflats, with tides travelling at up to 20cm/sec mid cycle.
