Biodiversity
East of the Wallace Line, where species from Asia and Australasia share one island.
The Lombok Strait, only about 35 km wide but very deep, separates Lombok from Bali. In the 1850s the naturalist Alfred Russel Wallace noticed that the birds on either side were strikingly different. The line he drew through the strait marks the edge of the Asian continental shelf; east of it lies Wallacea, a zone of islands that were never joined to either Asia or Australia, where species from both continents mix and many are found nowhere else.
Some of the island's species
Rinjani scops owl
A small owl found only on Lombok, described to science in 2013 (Otus jolandae). Its call was known locally long before.
Javan langur
The black leaf monkey of Rinjani's forests, often seen near the Senaru and Sembalun routes.
Timor deer
The rusa deer of Lombok's forests and savannas.
Forest birds
Sunbirds, honeyeaters, pigeons and cockatoos from both sides of the Wallace Line.
Orchids and forest trees
Montane orchids, casuarina, and lowland forest trees such as banyan and wild figs.
Reef life
Corals, reef fish and sea turtles around the Gili islands.
