Amphibians are important component in the food network of tropical forest because they are likely to be the main terrestrial insectivores (Utama, 2003). According to Iskandar (1998), around 4,100 species of frogs and toads are recorded in the Anura tribe. Whereas Naming and Das (2004) estimated 155 species of amphibians in Kalimantan and most of the amphibians living in East Kalimantan inhabit forest areas and less diverse in rice fields, plantations, irrigation and settlements.
Amphibians are a good biological indicator of environmental quality in an area such as fragmented tropical forest. Amphibians are animals that are very dependent on humidity and the presence of water (in rivers & ponds) with good condition.
The types of amphibians found in the vicinity of the conservation forest and natural forests of Badak LNG are common and generally inhabit open areas and other coastal areas. Several types of amphibians that can be identified in this region consist of 4 families: Ranidae, Bufonidae, Rhacophoridae and Dicroglossidae.
The number of amphibians found in Badak LNG’s conservation forest increased 2023. To maintain sustainability of amphibians in the conservation forest, Badak LNG routinely monitors fauna in search of the number of species that exist. In the future, more specific monitoring will be carried out for individuals whose status is threatened.
