Sand Cay - Ecology

Ecology

Sand Cay has no source of natural fresh water, but the islet's coral sand is covered with a thin layer of fertile hummus mixing with guano. The vegetation mainly composes of Barringtonia asiatica, Ipomoea pes-caprae and Casuarinaceae's species as well as some kinds of grass. In recent years, islanders have cultivated fruit trees such as pomelo, jackfruit, dragonfruit, sugar-apple and guava. Sand Cay is usually visited by seabirds, and its surrounding water is rich of fish, sea snails and sea cucumbers.
