Site Overview


KBA status: confirmed

Rationale for qualifying as KBA: This site was originally confirmed as a KBA under legacy criteria for the Short-billed Dowitcher (Limnodromus griseus) and the Piping Plover (Charadrius melodus). Updated shorebird population data from a consolidated database of multi-year censuses across the Bahamas indicates that the Joulter Cays regularly supports wintering aggregations of Piping Plovers. Therefore, the productive sand flats of the Joulter Cays provide critical habitat for this declining species. The boundaries of the Joulter Cays KBA mostly match the boundaries of the Joulter Cays National Park, with the addition of a small area of ​​sand flats to the south that is commonly used by the wintering Piping Plover population of the Joulter Cays.

Site description:

The Joulter Cays lie on the margins of the Grand Bahama Bank north of Andros Island. It is a large intertidal to shallow subtidal area of stabilized sand flats that covers approximately 403.898 km². The sand flats are penetrated partly by tidal channels with grass beds. The flats area fringed on the windward eastern and northeastern boarders by mobile sands creating roosting habitats for shorebirds. On the seaward side there is a ridge of vegetated islands up to 7 m above mean sea level. The primary vegetation on the Joulter Cays is Red and Black Mangrove. Other vegetated islands are scattered among the sand flats. The sand bars are primarily made up of rare Ooid or Oolite sand. This unique spherical grained sand resembling Fish-roe is developed through a chemical process adding concentric layers around a central nucleus. The sands have a large surface area that promotes bacterial growth and are mainly used in the aquarium industry.
