| Popis: | Droughts in Serbia become more and more frequent, and depending on the intensity and duration, they significantly effect on the state of the vegetation and on the creation of conditions for the occurrence of fire. Long periods of drought are typical which increases the fire risk for flammable materials. The majority of dry periods during the year, in this area, occur during the period from June to September. In recent years, drought is has been recorded in October and even in November. This work presents a model that allows the determination of the risk of forest fires affected by drought. The analysis is based on the meteorological data obtained from 26 meteorological stations in Serbia in the period from 1981 to 2010. For evaluation of humidity, Lang’s monthly and yearly rain factor and the Standardized precipitation index (SPI) for the growing period has been used. The aim of this study was to evaluate factors of vulnerability of forests depending on the time of occurrence and duration of the dry season with the assessment of the fire risk degree. There is a correlation between the occurrence of drought and fires in the open air. In Serbia, the danger of forest fires caused by the drought is the greatest in August and July. Particularly affected are the areas where the number of dry days is greater than 20. Some practical data and arguments presented in this paper can be used by the relevant services in assessing vulnerability of forest on fires and implementation of the necessary preventive measures. It is necessary to launch a new scientific researches and to introduce new adaptive forest management in Serbia. The goal of management is to assess the long-term impact of drought and to determine what the community can do now and in the future to respond to these threats. |
