Included here is the Bismarck Archipelago, the Admiralty Islands and the Solomon Islands. All lie within the Pacific zone of Melanesia.

Bismarckian Swamp and Riverine Forests

On the Solomons these have developed near the coast in small areas of impeded drainage, in often less than about one square kilometer. They are characterized by the dominance of the endemic tree Terminalia brassii (Combretaceae), which can grow to heights of 40 m. It also occurs in the riverine communities where it may be associated with the small endemic tree Osmoxylon chrysanthum (Araliaceae).
