THE AREA ALONG THE KITABATANGAN RIVER IN NORTHERN BORNEO PROVIDES SOME PROTECTION FOR A SECTION OF LOWLAND RIPARIAN HABITAT. THESE HABITATS ARE THREATENED OVER MUCH OF BORNEO AS A RESULT OF SETTLEMENT AND FOREST LOSS. SEVERAL TOURIST LODGES HAVE BEEN ESTABLISHED AROUND SUKAU AND THESE PROVIDE DAY AND NIGHT CRUISES ALONG THE MAIN RIVER AND SOME SMALLER ADJACENT WATERWAYS. SIGHTINGS OF PROBOSCIS MONKEYS ALONG WITH SEVERAL OTHER PRIMATES AND A VARIETY OF HORNBILLS ARE ALMOST GUARANTEED. IN ADDITION ELEPHANTS, SALTWATER CROCOCODILES, ORANGUTANS, PLUS SUCH RARITIES AS CLOUDED LEOPARD, STORM'S STORK, AND FLAT-HEADED CAT ARE REGULARLY SEEN.
