How does oil palm plantation impact bird species diversity? a case study from PKWE Estate, West Kalimantan

Abstract. Ramlah S, Santosa Y, Santoso N, Rushayati SB. 2021. The variation of bird diversity in various oil palm land cover in North Mamuju, West Sulawesi, Indonesia. Biodiversitas 22: 3068-3074. The development of oil palm plantations provides various positive impacts. On the other hand, this development is suspected to bring negative impacts on biodiversity, especially reducing bird species diversity. Based on the other research, well-managed oil palm plantations that maintain high conservation value areas have high species diversity. This study aimed to identify bird species diversity in different types of oil palm plantation land covers in North Mamuju. Data observation of bird species was performed using the transect method. There were 4 transects on each land cover. The results of this study showed that the young oil palm area had a high index of diversity and species richness. The high species diversity in the young palm area was caused by habitat variations. There was a water flow that provides more feed sources. The distance between the young oil palm area and secondary forest area affected the number of species, species richness and diversity of bird species. The category of insectivore guild which included aerial insectivores and insectivores was the dominant guild in all types of land cover, both in the number of species and the number of individual abundances.

Gain And Loss

Changes in plants diversity occurring the establishment of oil palm plantations, have been considered as the reasons for the changing pattern in community livelihoods. Hence, the values of plants diversity to the local community worth considering. This research was conducted to identify the local communities’ perceptions related to gain and loss of plant species diversity due to the establishment of oil palm plantation. The study was carried out in the indigenous Dayak Villages of Tajok Kayong and Nanga Tayap, West Kalimantan Province of Indonesia in March 2018. Data were collected using field observation and interviews. Our results indicate that the establishment of oil palm plantation have resulted in the gain of 3 plant species and the loss of 8 plant species functional values (medicine and food). Nevertheless, as many as 75.68% of interviewed person stated that the presence of oil palm plantations increased plant diversity, in terms of flowering plants and other non-functional plants. These findings reveals that local community were not affected by the species loss since prior to the plantation’s establishment, their living patterns were already transformed into semi modern and modern living styles in which the people have lower dependence on their surrounding plants.

Research Objects

The study of replanting models for smallholding oil palm plantation analysis is focus on smallholders and cooperatives' readiness assessment involves in replanting and business development program. The research objects are four oil palm plantantion cooperatives (KPS) in Ophir, West Pasam: KPS Perintis, KPS Indah, KPS Maju and KPS Makmur. Smallholders readiness in replanting and business development program was assessed through three criterias, which are ability to repay of debt, good faith to join community, and cooperative capacity. The results showed that smallholders in KPS Ophir are basically ready and feasible in obtaining financing and follow the oil palm replanting program, but access to financing and regulations that requires avalis become constrains for the smallholders.
