Kalimantan

In the early years of this century a new name caused sensation in the world of marine biologist and divers: “Raja Ampat”! This remote area was newly discovered as the place with the richest variety of marine species in the world and with an ecosystem very well intact. An incredible 75% of all known coral species (537 species confirmed) appear to live in its seas. The amount of fish species count more than 1000. The density of marine life is as well amazing. The reefs of Raja Ampat are just as varied as the marine life. There are vertical walls, reef flats, slopes, sea mounts, mucky mangroves, lagoons and pinnacles.

Kalimantan is the Indonesian part of the island of Borneo, the 3rd largest island in the world. The Indonesian part covers some 580.000 km2 the vast area is home to only 12 million people, so most of the provinces, especially the interior is very sparsely populated, and the vast rain forests here is some of the most bio-diverse areas in the world and one of the last few places you can see Orangutans in the wild.

The Borneo rainforest is 130 million years old, making it one of the oldest rainforests in the world and 70 million years older than the Amazon rainforest. Borneo is very rich in biodiversity compared to many other areas. There are about 15,000 species of flowering plants with 3,000 species of trees, 221 species of mammals and 420 species of birds. It is also an important refuge for many endemic forest species, as the Asian Elephant, the Sumatran Rhinoceros, the Bornean Clouded Leopard, and the Dayak Fruit Bat.

Kalimantan has a tropical climate with the average temperature ranging between 23 and 31C.
