SUMMARY: The traditional area of the beaver (Castor fiber L.) inhabitation covers also the Croatian regions. At the end of the 19th century the beaver disappeared from almost the whole of Europe and the same fate also occurred to this species in Croatia. Data exist on its existence in the watercourses of Croatia, but since the beginning of the 20th century it has not been mentioned as a specimen of the fauna in this country. Interventions towards re-inhabitation of the beaver in the whole of Western Europe has contributed to its recovery, thus, nowdays there is no danger of its extinction. Research into active habitats of beaver in Bavaria served as a good basis for research into potential beaver habitats in Croatia. The composition of coastal and littoral vegetation, characteristics of watercourses, possibility of beaver dam construction and extremely favourable possibilities for natural spreading of its population were elements learned in Bavaria, and served as starting points for research in Croatia. During 1993 preliminary research was carried out at 15 localities in Posavina and Podravina as potential habitats for the beaver. The maintenance of strict criteria in the assessment of habitats some localities turned out to be extremely suitable for the beaver. These localities were examined in detail and the results of the preliminary investigation of their quality were confirmed. The Žutica localities with watercourses Česma and Lonja, together with Legrad with meandering courses of the Drava river, were planned for the beginning of the beaver re-inhabitation in Croatia. Composition of the vegetation, i.e. nutritional potential proved to be better than the average beaver habitats in Bavaria. The distance of agricultural land from the coast eliminates the worries of possible damage by the beaver on agricultural plants, and with this basic pre-conditions are achieved for normal and habitational dwelling of the beaver in these localities. The investigation results offer a sufficient number of arguments for further work on the re-inhabitation of the beaver in Croatia. |
