It is believed that the name of Kampung Mumiang, Sukau and Bilit located in the district also comes from the Chinese language.

[1] Some sources stated that Kinabatangan was already used by the locals as recorded in the books of French authors in 1782 and 1837, long before the arrival of Chinese immigrants to the area.

Scattered in the area are limestone outcrops, many with caves that harbour large nesting colonies of echolocating swiftlets, as well as endemic limestone-inhabiting flora and fauna, such as Diplommatinidae snails.

The recognition is significant, as the wetlands comprise rarely found coastal mangrove swamps and peat jungles.

[4] As in other districts of Sabah, there are a significant number of illegal immigrants from the nearby southern Philippines, mainly from the Sulu Archipelago and Mindanao of whom are not included in the population statistics.
