The objective of the study was to contrast the effects of different management systems on demographic characteristics and the long-term sustainability of population. Bear mortality (2005-2010 ; n=614, n=535) and census data (2004-2011) for Slovenia and Croatia, respectively, were used. The largest proportion in the total reported mortality was legally hunted animals, 68% in Croatia and 64% in Slovenia. Test for equality of proportions indicated the proportion of intervention removals in Slovenia (16, 6%) was significantly higher than in Croatia (5, 2% ; ?-sq.= 35.8, df=1, p<0.0001). The proportion of males hunted within the given quota was significantly (? -sq.= 29.63, df = 1, p<0.0001) larger in Croatia (77%) than in Slovenia (58%). The analysis of deviance for count data indicated the difference between average age of bears killed in quota in Croatia (5.2+0.17 years ; 1 s.e., n=364) and Slovenia (3.1+0.14 years ; 1 s.e., n=386) was significant. Survival analysis run in "R2.14.0" showed survivorship until the end of the 4th year of life was 0, 23 in Slovenia and 0, 49 in Croatia. Survival rate for cubs of the year derived from census data was 0, 87 in Croatia and 0, 88 in Slovenia. These results were obtained with assumption of two closed populations although we are aware bears belong to a single population with a lot of cross border movements. ArcGis spatial analyses showed that 75% and 50% of females and 99% and 55% of males in Slovenia and Croatia, respectively, were killed in a distance of average diameter of home range from the national border. Conclusions support need for transboundary coordination and population level management in future decision-making process.
