1 . Tokelau     Tokelau
Tokelau is a group of three small coral atolls, each with numerous islands on its rim. The lagoons are shallow with large numbers of coral outcrops, while the maximum height of the islands is about 4.5 meters. None of these atolls has a deep channel into the lagoon, making boat access difficult. The area has been affected by cyclones on a number of occasions, including 1987, 1990 and 1991. Detailed information about the biodiversity of these reefs is unavailable, but it is likely to be similar to that of the Samoan Islands to the south and Tuvalu to the west.

Tokelau, a territory of New Zealand, is heavily dependent on financial support for development. Concerns about degradation of the natural environment from overfishing and sewage pollution have led to some efforts to improve environmental management. There is a small fish processing plant on Atafu which prepares sundried tuna. At the end of the 1990s the overall threats were very low, although there had been depletion of a number of species such as giant clam and trochus. There is a relatively small population and there are very few visitors.
