  Site Description  
  The island is roughly circular in shape with an average diameter of about 15km and an area of about 200 sq km. According to hoogerwerf (1966), Bawean island is built up from remains of an old volcano with a maximum altitude of 655m. The oldest, outermost crater is no longer easily distinguishable, but a more recent crater containing the lake Telaga Kastoba is easy identifiable. This lake has a length of 600m, a width of 400m and a depth of 140m. A large number of smaller hills are found on the flanks of the central cone. Near the coast the soils consists of alluvial river deposits of grey clay. Such areas are used for growing rice. Hot springs in limestone are found at four different elevations on the island. There are many streams coming down from the hills. Along the coast there are small patches of mangrove or tidal forests characterized by species as Sonneratia alba. Most of the human population is concentrated near the coast and on the south side of the island. Principal vegetation: Mangal communities including including Sonneratia alba, Rhizophora mucronata, Hibiscus tiliaceus, Vitex sp., Canarium asperum, Pternandra coerulescens, Ixora sp., Ficus sp., Symplocos adenophylla, Eugenia lepidocarpa.
