Variation of climate in the region of Gorski kotar

Climate is a complex ecological factor described by different climate elements and events that affect vegetation development and its natural distribution. For forest vegetation, the most important factors are air temperatures, amount of precipitations, air humidity, snow and wind. The aim of this research was to determine changes of climate elements in Gorski kotar region. The increasing or decreasing trends of individual climate elements were analysed using the linear trend method. Values of climate elements from the referent line were compared to the period from 1991 to 2007. For the research of climate element trends in the region of Gorski kotar the meteorological stations with the longest period of observations were chosen. Trends of air temperatures at all meteorological stations were positive. Negative trend of annual precipitation was recorded at all meteorological stations. Trend of days with snow and maximal snow height showed the smallest changes. Forest vegetation in the region of Gorski kotar is adapted to certain climate conditions that are predominant in this region. These conditions change through time, and this reflects on growth and development of all organisms. Assumed climate variations can lead to changes in spatial distribution of forest vegetation, change in composition, structure and productivity of forest ecosystems, change in ecological stability, health status of forest as well as non-wood forest functions.
