Kuntoro Bayu Aji Reptile Diversity Distribution in Several Habitats of Taman Nasional Lore Lindu. Indonesian biodiversity facing a serious challenge in terms of identification of species contained therein. The conservation of species cannot be separated from the ecosystem. Lore Lindu National Park is a representative of humid tropical forest ecosystem types with high biodiversity inside. Including the diversity of reptiles species. Diversity of reptiles species and it is distribution pattern is studied in this research. The study was conducted in June-August 2008 in Lore Lindu National Park. The research site area inside the park is in Resort Lindu and Resort Mataue. Materials used in this study is the type species of reptiles and their habitats as well as alcohol. The equipment used is standard equipment for collecting reptiles species data using visual encounter survey method. Including RBI map sheet 2114-41 and 2014-62, reptiles observation equipment, documentation equipment, GPS receivers, stationery, and computer hardware and software. Reptiles data collection based on visual encounter survey method. Habitats vegetation analysis based on quadrats transect line described by Oasting (1948). Only captured or documented reptil species that can be identified which entered into the list of species found. Reptiles species data observation using active searching reptiles specimen and glue trap. The result, 17 reptiles species can be identified from the research area. Six species distributed inside plantation habitat type, eleven species inside the transitions areas habitat type, and seven species inside the forest. Transitions areas habitat type form the highest reptiles species richness. Shown by species list and Margalef’s index. But there inside Eutropis multifasciatus dominating significantly. Forest habitat type is the highest reptiles species diversity value shown by Shannon-Wiener Index. Although the number of reptiles species distributed there in less than transition areas, the reptiles species distributed more evenly.
