Sumbawa is an Indonesian island, located in the middle of the Lesser Sunda Islands chain, with Lombok to the west, Flores to the east, and Sumba further to the southeast. Along with Lombok, it forms the province of West Nusa Tenggara, but there have been plans by the Indonesian government to split the island off into a separate province. Traditionally, the island is known as the source of sappanwood, as well as honey and sandalwood. Its savanna-like climate and vast grasslands are used to breed horses and cattle, as well as to hunt deer.
