In order to study the influence of climatic factors on the participation of the young in the population of brown hare in Vojvodina, in the period from 1993 to 2008 data have been processed for the average monthly temperature and rainfall by month of brown hare reproductive activity (March–August) on the % of participation of the young in the population. The average number of brown hare in Vojvodina in the mentioned period was 261,216, with expressive cycle. The minimum number of 204,528 brown was recorded in 2001, and the largest in 1995 – 326,901. At the same period the average yearly shooting was 41,115 specimens, most shoots were made in 1994 – 65,848 specimens, while the smallest shooting was recorded in 2002 – 25,753 brown hare. In order to test the age of the rabbit on the basis of eye lenses weight and determining the % of the young processed a total of 133,545 eye lenses for 16 years, with yearly average of 8,346 eye lenses. The average percentage of the young brown hare in the observed period was 60%, which is very good. The average percentage of the young shows cycle depending on climatic factors. The highest % of young brown hare was established in 1994 and was 70%, while the lowest % of the young was in 2006 – 50%. On the basis of regression analysis there has been found a small dependence on % of the young brown hare on the temperature and precipitation in the reproduction period from March to August for the last 16 years which is not statistically significant.
