Source from Mr. Lee Shing Fang
Pratas Island is short of soil. Its surface is covered by white
sand (weathered shells and coral); the middle layer is phosphate,
in the form of guano, but not of sufficiently high quality to warrant
extraction; the lower level is coral reef base rocks. The sea near
the islands contains potential reserves of petroleum and natural
Plants and Birds
The plants on the island are mostly low bushes, shrubs and tropical
vines. Silver silk tree, strawberry tung tree and coconut tree are
the main species. In addition, the soldiers have also planted vegetables
and fruits on the island. The birds are mostly distributed along
the coast in the shoals and lagoons. There about fifty species of
birds, including Little Terns, Turnstones, Gullbilled Terns...etc.
Most of them are migratory birds or seabirds.
