The body was found stuck between water hyacinth and heavy mud near Bukabil camp under Kohora Range by a routine patrolling party of the Forest Protection Force Battalion, said Kohora Range Officer Ranjit Baruah.
The young elephant of about five years age died due to starvation as he got stuck for over three to four days, Baruah said.
After the recent floods all low-lying areas in the rhino habitat has been submerged and heavy siltation by the Brahmaputra was causing mud to be collected, he said.
