Methodology has been developed for estimation of population size and study of social behavior of wild elephants in Salak Phra Wildlife Sanctuary, Kanchanaburi Province, using non-invasive sampling of microsatellite markers from DNA.Two Ph.D. students have recently developed a sufficient number of primers for hypervaiable microsatellite loci which can be used for fingerprinting elephants. These are being used for estimating the elephant population in Salak Phra WS where 500 dung samples have been collected. A marker has been found for sexing the elephants. Juvenile elephants can be indentified and approximately aged from the sizes of dung balls
