Bawah’s location is remote – there are no other islands closer than around 20 nautical miles. This means that Bawah has an independent ecosystem.
Bawah’s ecosystem includes rare and endangered species of flora and fauna, coral reefs that support a wide variety of marine life, and mangroves between the terrestrial and marine environments.
Although there are no mammals (apart from humans) on the island, there are many types of lizards, mangrove snakes, pythons, and a great variety of birds.
Initial research by arboriculturalists has identified the presence of some trees that are at least 2000 years old, underlining the vital importance of protection and conservation of the islands.
The forest on Bawah comprises a total of 576 individual trees with a trunk diameter greater than 30
cm. Canopy trees with the highest density include the Keruing (Dipterocarpus grandifloras) (104
individual trees), Sindora coriacea (37 individual trees) and Canarium hirsutum (30 individual trees).
Other flora includes: Sea Hibiscus (Hibiscus tiliaceus) and Benth (Serianthes grandiflora).
The mangroves dotted around the islands are also extremely important in sustaining marine life
(acting as a nursery to protect juvenile fish), and supporting the growth of other types of vegetation.
Species of mangrove recorded on Bawah include Aegiceras corniculata, Bruguiera gymnoriza,
Rhizophora stylosa, Pempis accidula, Xylocarpus granatum and Heritiera littoralis.
The diversity of species of marine life around Bawah is extensive. We have conducted two Reef
Health Monitoring surveys in collaboration with National University of Singapore and a team of
Indonesian Marine Biologists. To date 240 species of reef fish have been recorded from Bawah’s
south eastern reefs, including the Foxface (Siganus vulpinus), Humphead Bannerfish (Heniochus
Varius), Indian Parrotfish (Chlorurus capistratoides), Humphead Parrotfish (Bolbometopon
muricatum), and a variety of Butterflyfish (of the family Chaetodontidae). Other marine life
frequenting the waters around Bawah include: Blue-spotted Ribbontail Ray (Taeniura lymma),
Blacktip Reef Shark (Carcharhinus melanopterus).

We employ two on-site marine biologists who have so far built 10 coral tree nursery areas, growing staghorn coral fragments for transplanting onto artificial reefs (hexadomes).
Around Bawah, there are Green Sea Turtles (Chelonia mydas) and Hawksbill turtles (Eretmochelys
imbricate), and to protect these endangered creatures, the Bawah Anambas Foundation is building a
turtle semi-natural nest and hatchery. The goal is to protect the turtles from natural predators such
as monitor lizards. and consequently, increase the population of turtles here in the region.

Flying fox bats (Pteropus hypomelanus) are also a common sight around Bawah, as are Asian water
monitor lizards (Varanus salvator), Great Eggfly Butterfly (Hypolimnas Bolina), White-bellied Sea
Eagles (Haliaeetus leucogaster) and Collared Kingfishers (Todiramphus chloris).
According to the World Resources Institute, scientists have a better understanding of how many
stars there are in the galaxy than how many species there are on Earth. What we do know is that
the speed of loss of species is estimated by experts to be between 1,000 and 10,000 times higher
than the background (natural) extinction rate. With this knowledge comes the responsibility to
protect and conserve the full range of species, particularly in places where this diversity is at its
greatest, such as Bawah and the wider Anambas region.
