[1] The Tuamotus are mostly low coral atolls, with the exception of Makatea, which is made of coralline limestone raised 100 meters above sea level by tectonic activity.
The forest grows more diverse inland, and includes Pisonia grandis, Pandanus tectorius, Pipturus argenteus, Sesbania coccinea, Cordia subcordata, Morinda citrifolia, and Calophyllum inophyllum.
[1] The coastal plateaus of uplifted coralline limestone are home to a tall and dense forest of Pisonia grandis, Pandanus tectorius, Ficus prolixa, Homalium mouo, Guettarda speciosa, and, on Makatea, the endemic palm Pritchardia vuylstekeana.
The plateau forest on Henderson also includes Thespesia populnea, Bidens hendersonensis, Celtis sp., Nesoluma st-johnianum, and Geniostoma hendersonense.
[1] The higher-elevation interior forests on Pitcairn are characterized by the trees Homalium mouo, Metrosideros collina, Ficus prolixa, Pandanus tectorius, and Thespesia populnea.
Coprosma benefica and the endemic fern Angiopteris chauliodonta have very small populations, and over-harvesting by islanders has caused Cyclophyllum barbatum and Psydrax odoratum to dwindle in numbers.
The lack of fruit-eating birds on Pitcairn has limited the dispersal of C. benfica, P. odoratum, and Xylosma suaveolens, decreasing these plants' ability to recover from disturbance.
These remnant habitats are vulnerable to invasion by exotic plants, like lantana or rose-apple, which would make them unsuitable for the land snails.
In 1790, nine British mutineers from HMS Bounty and their Tahitian companions settled on Pitcairn, and with a brief interruption their descendants have lived there since.
Much habitat has been destroyed by conversion to agriculture including coconut plantations, overgrazing, and frequent human-caused fires.
In the Gambier Islands, one patch of native forest survives on Mont Mokota on Mangareva.
