Abstract
A large number of forests at Munggu Village, Ngabang District, Landak Regency have been converted into oil palm and rubber plantations. As consequences, natural habitats in the region have been fragmented and species diversity, including herpetofauna, has been decreased. This study aimed to assess herpetofauna diversity in four different habitats in Munggu Village: (1) forests, (2) Landak river, (3) tourist areas, and (4) rubber plantations. Data collection used Visual Encounter Survey (VES) for 8 days.[u1] The results showed that the total of 24 herpetofauna species: 15 amphibians’ species (4 families) and 9 reptiles species (6 families) have been recorded from the four sampled areas. Of the four locations 11 species were found in river habitat in the forest, 4 species in the location of Landak river, 8 species in tourism sites and 9 species in rubber plantations. The Shannon-Wiener (H') diversity index in all four habitats was classified as moderate. In the river location in the forest, H' was 2.14, in the Landak river it was 1.28, in the tourism sites it was 1.71 and in the rubber plantation it was 1.87. However, the evenness index (E) for the herpetofauna community in all four locations was >0.80. Habitat loss and habitat destruction are among the causes of decline in amphibian and reptile populations. Knowing the diversity of herpetofauna, it is hoped that the community and stakeholders can collaborate to secure the herpetofauna in Munggu Village.
Highlights
IntroductionMost of the areas of Munggu Village are oil palm, rubber, and forest plantations, which are used as illegal mining areas
The results showed that habitat loss and habitat destruction are one of the main causes of the decline in amphibian (Stuart et al, 2004; Rowley et al, 2009) and reptile populations (Gibbons et al, 2000)
The study was conducted at Munggu Village, Ngabang District, Landak Regency, West Kalimantan Province, Indonesia, that were divided into four localities based on their habitat types (1) rubber plantations; (2) forest; (3) Landak river; and (4) tourism sites of the Riam Setegong
Summary
Most of the areas of Munggu Village are oil palm, rubber, and forest plantations, which are used as illegal mining areas. This has caused a part of the forest near the village to be converted, even though the land is included in the watershed conservation area that has been protected by local government laws. The variety of land cover types allows for the potential diversity of herpetofauna, and the area around the village still has many rivers and waterfalls. The results showed that habitat loss and habitat destruction are one of the main causes of the decline in amphibian (Stuart et al, 2004; Rowley et al, 2009) and reptile populations (Gibbons et al, 2000)
