STATUS AND TRENDS IN MANGROVE AREA EXTENT WORLDWIDE (original) (raw)
Solomon Islands
Vegetation description
Occurring in sheltered coastal bays and along river mouths, two structural types of mangrove forest can be distinguished: one is a low, stunted, 2.5 m tall forest dominated by Rhizophora apiculata; the other is up to 25 m tall and composed of Bruguiera parviflora, B. sexangula, Rhizophora apiculata and R. stylosa, with local populations of Dolichandrone spathacea. Other mangrove species include Ceriops tagal and Lumnitzera littorea, the latter sometimes forming pure stands. The palm Nypa fruticans is also present. Differing structure and composition are related both to habitat differences and to past habitat disturbance.
