ロンボク海峡
The ecoregion includes a chain of volcanic islands in the Lesser Sunda Islands. The Lombok Strait lies at the western end of the ecoregion, separating Lombok from Bali. The Lombok Strait is part of the Wallace Line, a major biogeographic boundary separating the Indomalayan and Australasian biogeographic realms. The ecoregion is part of Wallacea, a group of islands that are part of the Australasian realm, but were never joined to either the Australian or Asian continents. The islands of Wallacea are home to a mix of plants and animals from both terrestrial realms, and have many unique species that evolved in isolation.
