Bantimurung Bulusaraung National Park (BabulNP) was gazetted in 2004 to protect the region’s biodiversity and karst ecosystem. However, the park’s herpetofauna is almost unknown. This project consists of three programs: herpetofauna survey in BabulNP, herpetofauna conservation education to local schools, and herpetofauna training for locals and was conducted from July to September 2007. Based on the survey conducted in six sites in the park, we recorded 12 amphibian and 25 reptile species. Five of those species (Bufo celebensis, Rana celebensis, Rhacophorus monticola, Sphenomorphus tropidonotus, and Calamaria muelleri) are endemic to Sulawesi. Two species of the genus Oreophryne are still unidentified. We visited six schools around the park for our herpetofauna conservation education program. The Herpetofauna Observation Training was held over four days with 17 participants from BabulNP staff, local NGOs, school teachers, and Hasanuddin University students. i Conservation of Herpetofauna in Bantimurung Bulusaraung National Park, South Sulawesi, Indonesia Acknowledgements This project would not have been possible without the contribution of many persons. We would like to express our gratitude to BP Conservation Leadership Programme for providing funding.

  • The 2008 IUCN Red Listings of the World's Small Carnivores
    The 2008 IUCN red listings of the world’s small carnivores Jan SCHIPPER¹*, Michael HOFFMANN¹, J. W. DUCKWORTH² and James CONROY³ Abstract The global conservation status of all the world’s mammals was assessed for the 2008 IUCN Red List. Of the 165 species of small carni- vores recognised during the process, two are Extinct (EX), one is Critically Endangered (CR), ten are Endangered (EN), 22 Vulnerable (VU), ten Near Threatened (NT), 15 Data Deficient (DD) and 105 Least Concern. Thus, 22% of the species for which a category was assigned other than DD were assessed as threatened (i.e. CR, EN or VU), as against 25% for mammals as a whole. Among otters, seven (58%) of the 12 species for which a category was assigned were identified as threatened. This reflects their attachment to rivers and other waterbodies, and heavy trade-driven hunting. The IUCN Red List species accounts are living documents to be updated annually, and further information to refine listings is welcome. Keywords: conservation status, Critically Endangered, Data Deficient, Endangered, Extinct, global threat listing, Least Concern, Near Threatened, Vulnerable Introduction dae (skunks and stink-badgers; 12), Mustelidae (weasels, martens, otters, badgers and allies; 59), Nandiniidae (African Palm-civet The IUCN Red List of Threatened Species is the most authorita- Nandinia binotata; one), Prionodontidae ([Asian] linsangs; two), tive resource currently available on the conservation status of the Procyonidae (raccoons, coatis and allies; 14), and Viverridae (civ- world’s biodiversity.

  • Indonesia 24 September to 15 October 2013
    Indonesia 24 September to 15 October 2013 Dave D Redfield Mammal Tour Picture: Sunda Flying Lemur (Colugo) with young by Richard White Report compiled by Richard White The story: 5 islands, 22 days and 52 mammals... A journey to a land where lizards fly, squirrels are the size of mice, civets look like otters and deer are no bigger than small annoying poodles...Indonesia! Where did this all begin...? In late June I was thinking of heading to Asia for a break. After yet another Tasmanian winter I wanted to sweat, get soaked in a tropical rain shower, get hammered by mosquitoes...I wanted to eat food with my hands (and not get stared at), wear sandals, drink cheap beer...and of course experience an amazing diversity of life. While researching some options I contacted my former employer and good friend Adam Riley from Rockjumper Birding Tours/Indri and he suggested I touch base with a client that I had arranged trips for before. The client (and now friend!) in question, Dave Redfield, has seen an aPD]LQJYDULHW\RIWKHZRUOG¶VPDPPDO species but, at that time, had yet to visit Indonesia. So, armed with a target list and a 22 day budget, I sat down and began researching and designing a tour in search of a select suit of mammal species for Dave. Time, terrain, concentration of species and cost were considered. We settled on a few days in mammal hotspots on Java, Sumatra, Borneo, Sulawesi and finally Bali, in that order. %DOLZDVDOVRFKRVHQDVDJRRGSODFHWRZLQGGRZQDIWHUµURXJKLQJLW¶ though the rest of Indonesia. It is also worth mentioning that Dave, realising that seeing all the ZRUOG¶Vmammals in the wild is an impossible target, does count mammals seen in captivity; the target list of species was thus not what one might have expected (for example, a Red Spiny Mouse was a priority but Babirusa was not).

  • ABOUT BOOKS Opposite Sides of the Same Coin
    ABOUT BOOKS Opposite Sides of the Same Coin Mark Lynch Threatened Birds o f the World. 2000. Alison J. Stattersfield and David R. Capper, project managers and senior editors. London, England: Bird Life International, and Barcelona, Spain: Lynx Edicions. 852 pages. $115.00. Bill Oddie's Gripping Yarns: Tales o f Birds and Binding. 2000. Bill Oddie. London, England: Christopher Helm. 224 pages. $14.95, paperback. These two books could not be more different in tone, intent, execution, scope, and even size and weight. They represent the two seemingly polar opposite aspects of birding: one concerned with the enviromnent, preservation of habitat, and the fate of the natural world; the other wrapped up in a single-minded pursuit of what could be seen as stamp collecting with feathers. It’s the old ornithology versus birding problem. Hopefully, it is apparent to all that the fun and craziness of birding is totally dependent on the health of our enviromnent. Threatened Birds o f the World is Bird Life International’s hard copy of the massive World Bird Database (WBDB), extensive data files on all the species of endangered birds. The WBDB was started in 1994 and contains much more information than could possibly be put even into this hefty book. Nearly 1000 people contributed to this important volume, which is now considered the official source for birds on the International Union for Conservation of Nature and Natural Resources (lUCN) Red List. The publishing of this book is equivalent to issuing an up-to-the-minute state-of-the-world summary of avian life on the planet.
