Buka trees (pisonia grandis)

[[File:Buka-forest.jpg|thumb|300px|Buka forest. Niku V (2007). "Pisonia grandis is a species of flowering tree in the Bougainvillea family, Nyctaginaceae, that is distributed throughout the coral cays of the Indian and Pacific Oceans. The species often dominates mature coral cay vegetation, growing in dense stands up to 20 metres (66 ft) tall. Pisonia wood is rather weak and soft and decays rapidly when the trees fall."[1]
