Site description (baseline)
Starbuck Island is a low-lying island with a dry climate. The interior contains several dark-coloured saline lagoons which at times dry out completely. Starbuck rises from its reef fringed coast to a steep beach crest before descending into a slight interior depression.

Key biodiversity
The island is importantly primarily for its large sooty tern population. There is little information on other species present.

Non-bird biodiversity: Green turtles may use the island for egg-laying, although there is no information on counts. An endemic plant, Bidens kiribatiensis has been identified from the island (Garnett 1983).
