Abstract

In 2015, Bali Barat National Park was chosen for a Rainforest Standard (RFS) demonstration project. As part of the requirement for the Protected Area Credit of the RFS, species or a group of species that can act as indicators of ecosystem health in Bali Barat National Park (BBNP) have to be identified. Butterflies was one of the taxa assessed for this purpose. A biological survey was conducted in Bali Barat National Park during August-September 2015. Butterfly species were surveyed using a modification of Pollard walk methods by recording species while walking along transects. A total of 82 butterfly species were recoded representing the families Papilionidae, Nymphalidae, Pieridae, Lycaenidae and Riodinidae.
