Natural hazards: serious maritime hazards because of numerous banks, reefs and shoals The islands are most likely volcanic in origin. The islands themselves contain almost no significant arable land and have no indigenous inhabitants, although twenty of the islands, including Itu Aba, the largest, are considered to be able to sustain human life. Natural resources include fish, guano, undetermined oil and natural gas potential. Economic activity includes commercial fishing, shipping, and tourism. The proximity to nearby oil- and gas-producing sedimentary basins suggests the potential for oil and gas deposits, but the region is largely unexplored, and there are no reliable estimates of potential reserves. Commercial exploitation of hydrocarbons has yet to be developed. The Spratly Islands have at least three fishing ports, several docks and harbors, at least three heliports, at least four territorial rigging style outposts (especially due west of Namyit), and six to eight airstrips. These islands are strategically located near several primary shipping lanes.
Coral reefs are the predominant structure of these islands; the Spratly group contains over 600 coral reefs in total.
Little vegetation grows on these islands, which are subject to intense monsoons. Larger islands are capable of supporting tropical forest, scrub forest, coastal scrub and grasses. It is difficult to determine which species have been introduced or cultivated by humans. Itu Aba Island was reportedly covered with shrubs, coconut, and mangroves in 1938; pineapple was also cultivated here when it was profitable. Other accounts mention papaya, banana, palm, and even white peach trees growing on one island. A few islands which have been developed as small tourist resorts have had soil and trees brought in and planted where there were none.
The islands that do have vegetation provide important habitats for many...
