| Title : | DETERMINATION OF FOREST DECLINE DUE TO THE ACTION OF DOMINANT STRESS FACTOR THROUGH MONITORING OF DEFOLIATION - CASE STUDY OF MALJEN, SERBIA |
| Abstract : | The paper presents the results of research on the influence of climatic factors on the occurrence of defoliation and decline of forests as a final outcome. The research was conducted in a mixed beech and fir forest, in the period from 2004 to 2019 at sample plot 415 - Maljen, as a representative example of forest decline, which is part of regular monitoring conducted on the territory of the Republic of Serbia. Due to the fact that defoliation may be due to the influence of various factors, research, analysis and results are focused on long-term trends. Special attention is paid to the analysis of the degree of influence of climatic parameters on the occurrence of defoliation. Data on temperatures and precipitation in the period 2004-2019 were processed and analyzed on a monthly and annual basis, as well as in the vegetation period, for the main meteorological station Valjevo, which is closest to sample plot 415. Also, drought assessment was performed during this research period based on Lang's rain factor, de Martonne aridity index and climate diagram by Walter. In order to confirm these methods, the Standardized Precipitation Index was calculated as one of the method that has been mostly used in drought identification lately. It was stated that the defoliation of trees was initiated by extreme climatic events during three consecutive drought years (2011-2013), after which there was the largest decline of forests in the researched area. |
