摘要

The Asian elephant (Elephas maximus) is believed to number about 45,000 in the wild and is distributed across several populations over South and Southeast Asia. It is an important flagship species for the conservation of biodiversity as well as being a cultural symbol of the people of this region. We analyse a Geographical Information System database of administrative forest divisions constituting four Project Elephant Reserves designated for southern India, in an attempt to prioritize them for specific conservation action and funding allocation. We compute a conservation value for each of these divisions by using five variables characterizing habitat, population and biodiversity attributes. We also compute threat values for each, using two variables which represent the most significant threats. Based on a cluster analysis we demonstrate that divisions with high conservation values have large elephant distribution areas, preferred habitat areas and elephant numbers as dominant attributes. Divisions with the lowest conservation values are characterized by high levels of habitat fragmentation.
