The golden jackal (<Emphasis Type="Italic">Canis aureus</Emphasis>) in Bosnia and Herzegovina: density of territorial groups,population trend and distribution range

In this article, we present the results of the first systematic surveys of golden jackals in Bosnia and Herzegovina (B&H). The population status and distribution of the golden jackal (Canis aureus) in B&H was largely unknown, and the few existing literature records mention their presence at only five localities in the country. We interviewed managers of all the hunting grounds in B&H and reviewed available jackal hunting records from 2000 to 2016. In total, we collected 212 records of legally harvested jackals. We observed an increasing trend of harvested jackals in B&H (on average 35% annual increase) during this same period. Using the acoustic (playback) method, we confirmed the presence of 80 territorial jackal groups along six transects covering 3081 km². We estimated density to be a minimum of 0.33 groups/10 km² in northern B&H and 0.10 groups/10 km² in central B&H. Jackal groups were located at significantly lower altitudes with respect to available area along the transects. We present a distribution map of confirmed jackal occurrences in B&H, which indicates that the core area of jackal distribution in the country is currently located along the Sava River and its tributaries in the northern part of B&H. Jackals are sporadically present in the rest of the country, where gray wolves (Canis lupus) probably limit their presence. In total, jackal presence has been detected in 19% (109 out of 586) of 10?×?10 km grid cells covering the country. The primary factor driving the expanding population of jackals in northern B&H appears to be immigration of jackals from Croatia and Serbia.
