According to an ongoing survey carried out since April 2005 in the Sarigol National Park; northeastern Iran, the mating season of the Persian Leopard extends from mid-January to a peak in mid-Februar. Males and females associate briefly and just after the short mating period, they separate. We never found the leopards to raise more than two cubs. Most observations ofr leopard families were made in areas of high prey density. Our data verified by camera trapping indicate that track size alone is not reliable for the accurate identification of leopard age/sex categories.
