Site description
(I) Physical CharacteristicsPulau Kukup is located off the south-west tip of Johor State. The island is covered by mature mangrove forest, accreting towards the west and north-west, eroding in the south-east, and is a particularly good example of unexploited mangrove forest. Large mudflats are located to the north-west whereas severely degraded coastal mangroves (less than 500 m wide) are bunded on the landward side (DWNP, 1987; Junkov, 1999; Hawkins and Howes, 1986). (II) Climatic ConditionsPulau Kukup experiences a humid tropical climate with annual showers from both the NE and SW monsoons. The annual rainfall average ranges from 2,000 - 2,500 mm with an even distribution throughout the year (WIMP, 1999). Temperature ranges from 24.5oC to 26.5oC annually (IKAS, n.d.). The island experiences semi-diurnal tidal exposure of two high tides and low tides in a day (WIMP, 1999).

Key biodiversity
Pulau Kukup is an important feeding ground for the Lesser Adjutants and migratory shorebirds (5 species) (Noramly, 1998). The mangroves around the Kukup area are refuges for several globally Near Threatened species such as the Long-tailed Parakeet Psittacula longicauda, Chestnut-bellied Malkoha Phaenicophaeus sumatranus, White-chested Babbler Trichastoma rostratum and Mangrove Pitta Pitta megarhyncha (Anon., 1992).

Non-bird biodiversity: Unidentified dolphins have been seen using the channel between island and mainland. (I) Globally threatened mammals (IUCN, 2002): VULNERABLE: Smooth Otter Lutrogale perspicillata, NEAR THREATENED: Long-tailed Macaque Macaca fascicularis(II) Globally threatened reptiles (IUCN, 2002): None.(III) Globally threatened plants (IUCN, 2002): None.
