Introduction The wolf population in Croatia is part of the larger Dinaric/Balkan population that inhabits the territories of Slovenia, Croatia and Bosnia-Herzegovina, and continues to the south of the Dinarides mountain range. This entire population is estimated to contain approximately 3900 wolves, and has been predominantly stable over the past six years (Kaczensky et al., 2013). In Croatia, the wolf is permanently present throughout the Dinarides, from the border with Slovenia to the border with Montenegro. According to the distribution map from 2013 (Figure 1), the wolf in Croatia is permanently present in 18,213 km 2 and occasionally present in an additional 6,072 km 2 of territory. The distribution of the Croatian wolf population is distributed over nine counties: Sisak-Moslavina, Karlovac, Lika-Senj, Primorje-Gorski Kotar, Istria, Zadar, Šibenik-Knin, Split-Dalmatia and Dubrovnik-Neretva. There were no changes in the distribution range in 2014 as compared to 2013. Changes in the size of the distribution area are due to changing dynamics within the Dinaric wolf population, and also due to better knowledge of the population in Croatia. The dynamics of the Dinaric wolf population depend on the approaches taken in wolf management in each of the countries sharing this population. Figure 1. Distribution of the wolf population in Croatia (from: Kusak, 2013) 4 The wolf (Canis lupus ) is a strictly protected species in the Republic of Croatia pursuant to the Nature Protection Act (OG 80/13) and the Ordinance on strictly protected species (OG 144/13). All forms of intentional capture, killing or intentional disturbance are prohibited by law, particularly during the mating and young raising periods. Damaging or destroying mating areas or wolf resting areas is also strictly prohibited. The keeping, transport, sale, exchange or offering for sale or exchange of live or dead individuals from nature is also prohibited. The Ministry of Environmental and Nature Protection may permit derogations from these prohibitions only if there is no other suitable possibility, and if it will not harm the sustainability of the wolf population in a favourable state in their natural distribution range. All persons are obliged to report cases of captured and/or killed strictly protected animals to the State Institute for Nature Protection. The Republic of Croatia is a signatory to all the relevant international agreements in the area of nature protection. Significant acts for the protection of the wolf are the Act on Ratification of the Convention on Biological Diversity (OG-International Agreements 6/96), Act on Ratification of the Convention on the Protection of European Wild Taxa and Natural Habitats (Bern Convention) (OG-International Agreements 6/00) and the Act on Ratification of the Convention on International Trade in Endangered Animal and Plant Species (CITES) (OG-International Agreements 12/99). The European Parliament passed the Resolution (Doc. A2-0377/88, Ser. A) of 24 January 1989, calling European nations to urgent action to conserve the wolf, and adopted the Proclamation on the protection of wolves, inviting the European Commission to extend its support to wolf conservation. The main framework for conservation of the wolf in the European
