Megjegyzések:At the end of the reproductive period the age structure and the sex ratio of the populations are important parameters for the game management. The age estimation of the brown hare (Lepus europaeus, Pallas 1758) is possible in many ways.The two most important are on the basis of dried eye lens weight, and the existence of the Stroh-mark. These methods were applied during our survey in the hunting period of 2014/15 and 2015/16. In total 272 samples were collected from two hunting areas in Hungarian Great Plain in two hunting years. The aim of our work was to collect data concerning the age structure and sex ratio of the hare populations at the beginning of the hunting season and comparison of the two age estimation methods. After the huntings examining the hunting bag Stroh-mark were controlled in the field and eye lenses were taken from hares promptly. Lenses were fixed in 4% buffered formalin and after that lenses were dried in a thermostat at 102 oC in the laboritory. They were measured on a precise analytic scale (PRL-II) with precision of 1 mg. Animals were diveded into two groups: dried eye lenses <280 mg (juvenil) and >280 mg adult (based on Kőhalmy,1999). The data were statistically analysed (group-statistics, independent samples t-test, correlation analysis). As a result of our examination the range of the juvenile-adult ratio were in autumn: 0,51-1,96 (on basis of the dried eye lenses) and 0,60-1,95 (on basis of Stroh-mark). Between the two age estimation methods were statistically verified relationship (r=0,849; p<0,05) and (r=0,723; p<0,05). Although in both hunting period and hunting fields were found differences between the achievement of the two age estimating methods. These are only partial results of a long-term study which may be useful for wildlife management practice in the future.
