KEANEKARAGAMAN SPESIES HERPETOFAUNA PADA BERBAGAI TIPE TUTUPAN LAHAN DI LANSEKAP PERKEBUNAN SAWIT: Studi Kasus di PT. BLP Central Borneo

Abstract

The expansion of oil palm plantations in Indonesia is often blamed as the drivers of natural resource destruction and decrease the tropical biodiversity. Herpetofauna is one of biodiversity on oil palm plantation, but information about its species diversity is still limited. This research was aims to reveal the variation of diversity of Herpetofauna on oil palm landscape in central Borneo. Field inventory was conducted on seven types of land cover i.e. young oil palm, mature oil palm, old oil palm, High Conservation Value area, secondary forest, shrubs, and smallholder plantation. We used Visual Encounter Method to invent Herpetofauna spesies on all land cover type. This study reveal that the diversity of Herpetofauna species in PT BLP varies by land cover type. The land cover types of HCV and Secondary Forest have the largest number of species (12 species). Secondary Forest is the type of land cover with the highest abundance among other types of land cover, followed by old oil palm plantations. The oil palm plantations lanscape with different type of land cover can be part of the habitat for several Herpetofauna species and managed for sustainable oilpalm scheme.

Short Communication: The herpetofauna around human settlements in Lubuklinggau City, South Sumatra, Indonesia: Composition and diversity

“…This finding is not surprising because this species likes areas that have sufficiently thick bushes and grasses (Kamsi et al 2017). The number of T. sexlineatus individuals found in this study was higher than that reported by Kwatrina et al (2019) in the Landscape of oil palm plantation, i.e., 1 individual, presumably because the rubber plantation in Lubuklinggau had grasses, making it an ideal habitat for T. sexlineatus.…”

“…The presence of water, bushes, litter, and lush trees around the settlements make an ideal place for herpetofauna to live. The moist microhabitat, due to the tight canopy cover and lots of litter, becomes an influential factor on herpetofauna especially for amphibians (Wanger et al 2011;Qurniawan 2015;Kwatrina et al 2019).…”

“…Homogeneous microhabitats such as in the rice field reduce the number of niches which lead to the low diversity of herpetofauna (Muslim et al 2018). In addition, without litter and lack of tree canopy cover, the rice field has low relative humidity and high fluctuation of temperature between night and day, which cause herpetofauna diversity to decrease (Gillespie et al 2015;Saccol et al 2017;Kwatrina et al 2019).…”

Keanekaragaman Jenis Herpetofauna sebagai Dampak Pembangunan Perkebunan Kelapa Sawit di Sumatera Selatan

“…Herpetofauna memiliki peran terhadap fungsi kesuburan tanah, siklus nutrisi, pengurai biji, penyerbukan tumbuhan, dan sebagai predator dalam jaring-jaring makanan (Hocking & Babbit, 2014;Cortés-Gomez, Ruiz-Agudelo, Valencia-Aguilar, & Ladle, 2015). Menurut Kwatrina, Santosa, & Maulana (2019), keanekaragaman herpetofauna di perkebunan sawit dipengaruhi oleh ragam habitat. Selain itu, pertumbuhan, daya tahan, dan reproduksi herpetofauna juga dapat dipengaruhi oleh faktor lingkungan yang berdampak pada perubahan populasinya (Alford & Richards, 1999).…”

“…Setiap tipe tutupan lahan dibuat satu transect jalur dengan panjang 1 km dan lebar area pengamatan selebar 75 m ke arah kanan dan kiri jalur. Data yang diambil meliputi jenis yang ditemukan, jumlah herpetofauna, waktu perjumpaan, tumbuhan bawah, sumber air, suhu, dan kelembapan (Kwatrina et al, 2019).…”
