This paper analyzes the health status of trees in the avenues of the city of Sarajevo. Special attention is paid to abiotic harmful influences, snow precipitation and mechanical damage of trees, as the initial factors of destabilization of their health status.
Sarajevo area is characterized by a moderate continental climate occurring as a result of the influence of central European climate from the north and the Mediterranean climate from the south and of the variety of the terrain. This type of climate is characterized by hot summers and relatively cold winters. Because of severe thermal influence of the Adriatic Sea autumn is warmer than spring. Distribution of precipitation in Sarajevo is characterized by summer (primary) and autumn (secondary) peaks. Specific weather conditions in this area, in some years, result in early or late snowfall the consequences of which are damages of vegetation cover.
The results of this research confirmed significant damages of the trees resulted from the adverse effects of snow in October 2009 (branches fractures, split of the stem and fracture of tree crowns). The resulting injuries are suitable openings for the penetration of rot causing microorganisms (fungi and bacteria) and colonization of insects which is why we can expect further deterioration in the health status of trees in the future. The paper suggests activities the implementation of which can reduce these harmful effects of biotic factors.
