Megjegyzések:	The European brown hare is one of the most current and valuable small game species not only in Europe (COWAN,2004) but in Hungary as well. Population density in whole of Europe shows strong decreasing tendency. In the course of our monitoring demographic parameters of the European brown hare were examined. In the hunting season of 2014/15 we collected 235 samples from 2 typical habitats where the brown hare can be found in relatively high density. We analysed the data with the statistical program SPSS 22.(P <0,05). The following data were calculated: ratio of yearlings, coefficient of reproduction, reproduction index, sex ratio, coefficient of population increase, population increase by method Pintur et al (2006) and rate of utilisations by method Kovács and Heltay (1993). The future aim of our examinations is to determine the most likely reasons for the decreasing population of the European brown hare. To prove this, we collected a lot of data (body weight, gender, weight of perirenal fat, counts of placental scars, size of ovary, litter size, weight of the dried eye lens, the function of the testicle, weather data, predators data). On the basis of the data of hunting bag in both areas calculations were performed by the Kovács-Heltay model.
