Sadly, only two maximum of the cubs are managed to survive until adulthood, while weak law enforcement is believed as the main cause of the difficulty of combating tiger poaching activities.<br />During the period 1998-2009, as many as 46 tigers were found dead as a result of man-tiger conflicts and illegal hunting, meaning that an average of seven tigers had been murdered every-year in Riau province.
