Summary

Introduction

Asian elephant (Elephas maximus) is the largest terrestrial megaherbivore in Asia (Santiapillai & De Silva, 1994). Survival of the Asian elephant is endangered by habitat loss and conflict with humans over crop raiding (Sukumar 1989, De Silva 1998, Santiapillai & Jackson 1990, Corea, 2006). When considering the human population, Sri Lanka is one of the most densely populated countries (United Nations, 2008). It is a known fact that, the fragmentation and loss of the natural habitats of elephants (Desai, 1998) are considered to be the main cause of Human Elephant Conflict in Sri Lanka (Bandara, 2005). If the existing trend of habitat loss is continued, elephant is on the fast track to extinction (Santiapillai & De. Silva, 1994)
