Pisonia trees are distributed throughout the
coral cays of the
Indian and
Pacific Oceans. The species often dominates mature coral cay
vegetation, growing in dense, thick strands up to tall.
Pisonia wood is rather weak and soft and decays rapidly when the trees fall.
Pisonia forests are a common nesting site for
seabirds. One of the best remaining
Pisonia forests can be found on
Palmyra Atoll.
St. Pierre Island,
Farquhar Group, was once covered by a
Pisonia grandis forest. This forest disappeared after
guano mining between 1906 and 1972. The natural vegetation was destroyed in order to scrape the guano and the island's landscape became barren. ==Uses==
