N1 - Funding Information:
We thank the Ministry of Research and Technology of the Republic of Indonesia, particularly S. Wahyono and L. Shalahuddin for granting research permits to AATA. Also we thank the Ministry of Environment and Forestry (KLHK) and The Directorate General of Conservation of Natural Resources and Ecosystems (KSDAE) of the Republic of Indonesia for granting research and collecting permits. We would like to thank Tedi Sutedi (Head of TNBB) and all the staff of TNBB for providing all the support and facilities, and granting permits during the research as a collaborative party of the research. A. Riyanto, R. Ubaidillah, A. Hamidy, Syaripudin, W. Trilaksana and other staff members of MZB for facilitating in-house study of specimens under their care. We thank to Mulyadi, J.M.A. Ginting and D.F. Ekarini for their assistance during fieldwork, Maharadatunkamsi, Eko Sulistyadi and Nanang for the support. Fieldwork conducted by Amarasinghe and party in TNBB was funded by USAID University Partnership Program under the ?Strengthening Indonesia's Climate Change Mitigation Capacity Program? (Agreement No. AID-497?1-12?00009; March 2012 ? December 2015) partnership with Research Center for Climate Change at University of Indonesia (PI: Jatna Supriatna) and Center for Environment, Economy, and Society at Columbia University (PI: Don Melnick). The research was conducted as a part of a demonstration project for ?The Rainforest Standard?, developed in 2012 by Columbia University's Center for Environment, Economy, and Society; Bolivia's PUMA Environmental Fund Foundation; Brazil's Fund for Biodiversity; Colombia's Environmental Action Fund; Ecuador's National Environmental Fund; Peru's Trust Fund for National Parks and Protected Areas. J. Ramadhan is acknowledged for taking excellent photographs. Finally, we would like to thank Rebecca Johnson (Columbia University, USA) and Maya Dewi, D. Hartiningtias, and the staff of the Research Center for Climate Change, University of Indonesia, for their support.

N2 - We report on the results of a survey of the herpetofauna of West Bali National Park (Taman Nasional Bali Barat in Indonesian, hereafter TNBB) that was carried out in 2015. The survey also included other taxa and the motivation for it was to identify a species or group of species that could be used as indicators of management success for Protected Area Credits (PAC) under the Rainforest Standards (RFS™) system. Four major ecosystems, moist forest, deciduous monsoon forest, savanna and an abandoned Teak plantation, were sampled over a period of 10 days, using belt transects and pitfall traps. We measured species richness, abundance and density, herpetofaunal diversity (Simpson's Index of Dominance and the Shannon Weiner Index) and community similarity. We also estimated the indicator value to determine which species, if any, might be suitable as indicators of environmental conditions. The survey yielded 30 species, 12 frogs and toads, 7 snakes and 11 lizards. Out of them there is an endangered gecko, Cyrtodactylus jatnai, a vulnerable frog, Microhyla orientalis, and a vulnerable tree-skink, Cryptoblepharus baliensis. Diversity was highest in the moist forest, followed closely by both the deciduous forest and the savanna. The greatest abundance was found un the savanna, followed by the moist forest and then the deciduous forest. Both diversity and abundance were extremely low in the abandoned teak plantation. Eleven species were identified as potential indicators of environmental deterioration if their numbers were to decrease. Frogs and toads were the best indicators in the moist forest, while lizards were the most suitable indicators for savanna and deciduous forest. No snakes were identified as indicators. It is concluded that herpetofauna can be useful and cost-effective indicators of environmental change.
