The tiger reserve covers Udanti and Sitanadi wildlife sanctuaries and adjoining areas in the Gariyaband district and parts of the Sankara forest range in the Dhamtari district. On Saturday, an elephant attacked Bhumika Markam (38), a native of Paikbhata village, when she had gone along with other women to a nearby forest to collect wood, the official said. The other women managed to escape and informed locals, who then alerted forest personnel. The woman's body recovered from the spot after some people managed to chase away the tusker from the area, the official said.
