Demographics.
Ethnic.
The customs in Kaimana Regency, which because of its strategic location as a stopover (transit), have been influenced by culture from outside (social interaction) so that the indigenous values ​​of this area have been acculturated by the surrounding cultural values. People who live in inland mountainous areas have not been much influenced by outside interactions, while residents of coastal areas have had a lot of this influence through marriage, music/dance and clothing. Most of the inhabitants of Kaimana Kota District are in the villages. The inhabitants of Kaimana District, who are local tribes, are the largest population, followed by non-indigenous people (who come from outside areas) who are scattered in several villages in the Kaimana Kota kelurahan, such as Seram and Kaki Air. The non-indigenous population in these two villages is a spontaneous migration of the population from Maluku and South Sulawesi and the island of Java, who live in a pattern of clustered settlements in separate pockets of settlement. Indigenous indigenous people are found in the villages inside and outside the urban kaimana kota. The indigenous tribes include the Irarutu, Mairasi, Kambarau and Koiwai tribes. The distribution of the Irarutu tribe is in the southern area of ​​the Kaimana city and the tribe originates from the Teluk Arguni District. The Mairasi tribe originates from the interior of the eastern part of Kaimana and spread across the North East coast of Kaimana District. The Kambrau tribe originates from the Teluk Kambrau District, Kaimana District and the Arguni Bay area and is spread across the southern and northern coasts of the Kaimana Kota district. The Koiwai tribe originates from the western area of ​​Buruway District and the northern area of ​​the Kaimana District. This tribe mostly inhabits archipelagic areas.

In 2014 researchers revealed the level of biodiversity in the Lengguru area covering its coastal region and karsts. The expedition covered a range from 100 meters below sea level underwater up to 1,000 meters above sea level. Many species of flora and fauna were discovered, of which some are new species.
