Limmen Bight

It is bounded on the south-west by the Gulf Plains of the Northern Territory, on the north-west by the south-eastern coast of Arnhem Land, and in the north by Groote Eylandt.

[2] The extensive coastal mudflats provide feeding habitat for flocks of over 30,000 migratory waders, or shorebirds, and the freshwater swamps of the river floodplains are used by tens of thousands of waterbirds.

Threatened vertebrate species found in the area include the Australian bustard, masked owl, partridge pigeon and northern hopping mouse, as well as the flatback, green, hawksbill and olive ridley turtles.

[2] A 2234 km2 tract of land along the coast of the Limmen Bight has been identified by BirdLife International as an Important Bird Area (IBA) because it supports over 1% of the world populations of grey-tailed tattlers, great knots and white-headed stilts.

The main habitats are intertidal mudflats, low samphire shrubland, scattered patches of dry rainforest, and channel-fringing mangroves.
