Sumatran elephant ranging behavior in a fragmented rainforest landscape

February 2013

Increasingly, habitat fragmentation by agricultural and human development has forced Sumatran elephants (Elephas maximus sumatranus) into relatively small areas; yet, there is no information on the movements and home range behaviors of elephants on Sumatra. Using a GPS collar, we estimated the home range sizes of an adult female elephant (one of a herd of 40 to 60) in the Seblat Elephant Conservation Center (SECC),...

Human–elephant conflict: Do elephants contribute to low mean grades in schools within elephant ranges?

December 2012

  African elephant’ interfering with pupils’ attendance at school is one of the often mentioned, but less documented form of human-elephant conflict (HEC) and can result in reduced education standards of pupils and schools, human deaths and injuries and the retaliatory killing of elephants. This, however, has not been proven, apart from the anecdotal evidence; hence no mitigation measures have been...
