The connection between climate conditions and population size of most represented large game in a hunting area in Eastern Croatia in period 2008 - 2018

Climate change has an impact on population growth of red deer, roe deer and wild boar, on their survival and reproduction. When observing the climate of an area, air temperature is one of the main climatic elements. Besides, for the normal life of a wild animal, a significant factor is also humidity. Given the fact that populations of red deer, roe deer, and wild boar have great significance in Croatia, this study aimed to determine the relationship between population size of most represented large game and climate conditions in hunting ground in Eastern Croatia during the analyzed period from the year 2008 to the year 2018. The study was conducted in the area of Kućanci, Osijek-Baranja County. Data were given by Croatian Meteorological and Hydrological Service. Company Gavran d.o.o. is the owner of the population data and the hunting staff of the company made the investigation. Based on the conducted research following could be pointed out: the mean yearly air temperature varied in the interval from 11 – 13°C ; the mean yearly humidity varied in the interval from 76 – 84 % ; the total number of red deer was highest in 2015 when mean air temperature amounted to 12, 5°C ; the highest number of roe deer was recorded in the year 2009 when the mean air temperature was 12°C, humidity 82 % ; the highest number of wild boar population, males and females, was recorded in the year 2013, the mean air temperature was 12.5°C. Comprehending the climate effect on behavior is necessary to anticipate the number of new offsprings and to sustain stability in the hunting ground, when coming climate change may bring local weather variables different from the current range.
