Witkamp in 1924 saw few tracks on the upper Atan river, a tributary of the Klindjau.
In the subdivision Apo Kajan, there are still rhinos between Long Heban and Kiham Awon, on the upper course of the Iwan and that of the Maroeng (mountains on the divide with Serawak), and on the lower Kajan Ioet (report of 1930).
During the Midden-Oost-Borneo expedition of 1925, footprints, dung and paths of rhino were found in the Kong Kemoel mountains (2000 m high) and in the source areas of the Sungei Telen above Long Petah. According to a report by Siebers, the rhino hunters had then already gone to other places because there was too little game.

It is nowhere common.
In South Borneo the rhino is still found in the source area of the Barito, in the Schwaner Mountains (eg. upper Katingan river) and possibly in the Lower Kotawaringin (?), but nowhere common.
The rhino is reported from the hills and mountains of the Tidoengsche Landen (temesoer or temeroeh): the upper Sekatak region, area between the Malinau and Bahau (left tributary of the Kajan in Boelongan), the Krajan district upstream of the Pa Roengan and Kemaloet rivers, Mentarang district on the upper course of the Semamoe river, source areas of the Malinau and Toeboe. The Poenan-dajaks hunt the animal, but it is slowly confined to the mountains (Report 1930).
In the subdivision Beraoe there are still a few rhinos in the Njapa Mountains and the Soearan region, that is relatively close to the coast and the capital Tandjoeng Redeb. In 1930 the animal was called close to extinction. In 1935 another report from the same area called it rare.

The rhinoceros is increasingly confined to the mountains and even there it is not safe as it is hunted for its horns and hoofs. Despite close guarding, the animal iis still illegally hunted by the Dayaks which use a spear, lance and pit.
Since 1931 the rhinoceros is placed on the list of totally protected animals and it cannot be hunted or captured without a special license. Obviously the control on this law is very difficult in the extensive and inaccessible interior forests of Borneo. Export in the usual way of any body parts is no longer possible, thanks to a close supervision by the customs. It is, however, impossible to say to what extent there is illegal export. To safeguard for total extinction, guarded parks are a first way.

In Sangkoelirang the rhino seems to be absent.

In Boelongan, rhinos occur in the mountains, especially in the Bahau region. In 1930 they were hunted, and probably this continues still.
Mj?berg found fresh rhino tracks in 1925 in the area of the upper Sg. Boh (left tributary of the Upper Mahakam).
