Control of predatory population: jackal (Canis aureus) as a case of the study

Čagalj (Canis aureus) u Republici Hrvatskoj neprekidno širi svoj areal obitavanja zbog manjka prirodnih neprijatelja i obilja lako dostupne hrane. Cilj ovog rada je preko prikupljenih podataka na području Banovine utvrditi najbolju i najučinkovitiju metodu lova čaglja i utvrditi utječu li vremenske prilike na uspješnost lova čaglja. Tijekom 52 dana provedena u lovu, odstrijeljeno je 70 jedinki čagljeva, iz čega proizlazi da ukupni lovni napor iznosi 1,3 odstrijeljenih jedinki po izlasku u lov. Udio mužjaka među odstrijeljenim jedinkama iznosi 63%, a udio ženki 37%. Među odstrijeljenim jedinkama čagljeva najveći udio bile su jedinke između prve i druge godine starosti. Prema Nacionalnoj klasifikaciji staništa utvrđen je udio odstrela po tipu staništa. Najveći udio od čak 71% obavljen je na kultiviranim nešumskim površinama. Ukupan broj pojedinačno viđenih jedinki čagljeva bio je 191, od kojih je 68% viđeno na otvorenim, kultiviranim nešumskim površinama. Akustičnom metodom zabilježena su javljanja čagljeva na 44 lokacije. Javljanja čagljeva podjednako su bila zastupljena u šumama, šikarama i kultiviranim nešumskim površinama. 2% ukupnih javljanja čagljeva bilo je zabilježeno u blizini izgrađenih, naseljenih područja. Vremenske prilike su tijekom istraživanja utjecale na rezultate lova i lovni napor.Golden jackal (Canis aureus) in The Repulic of Croatia consistenlty widen their area of habitat because they lack a natural enemy while having an abundance of easy to reach food. The goal of this thesis is, with the help of collected data in the area of Banovina, to determine the best and most efficient method of hunting jackals and to determine if the weather effects the success in jackal hunting. During 52 days spent hunting, 70 individual jackals have been shot off, what gives us the combined huting effort of 1,3 shot off individual jackals per hunt. The share of males within the shot down individuals is 63% while there was 37% of females. The biggest share among the shot off jackals were between the first and second year of age. The share of culling was determined by habitat type, according to the National Classification of Habitats. Even 71% of the culling was done on cultivated, non-forrested areas. The summary of individually seen jackals totals to 191, of which 68% was seen on the open, cultivated, non- forrested areas. Using the acoustic method, jackal calls have been noted on 44 locations. Jackal calls were evenly distributed trough forrests, underbrush and cultivated non-forrested area. 2% of total jackal calls were noted in proximity of built, populated areas. The weather has during the reasearch affected the hunting results and huting effort
