Second year after the fire broke out on Vidlič Mountain during the summer of 2007, the changes of burnt down beech wood vegtation were recorded. Fitocenological research of the beeech wood habitat at the location of Visoka Stena two years after the fire, was carried out in accordance with Braun-Blanquet method. The results of the terrain research were given in the form of fitocenological table. It was noticed that the most present species were Rubus idaeus, Epilobium angustifolium, Galium mollugo, Doronicum columnae, Lactuca muralis and Securigera varia. Turf grass such as Brachypodium sylvaticum, Poa nemoralis, Poa badensis, Festuca varia, Festuca valesiaca and Agrostis capillaris was also present which is a significant factor in the succession process as grass is a powerful colonist. The conclusion was that revitalization of the beech wood depends on how much the beech trees had been destroyed by the fire.

Original scientific paper https://doi.org/10.2298/TSCI190412276RThe paper presents the results on the study of the possible application of the Canadian Forest Fire Weather Index and the Modified Angstrom Index in forest fire risk assessments. The daily values of these indices for the period 2005-2015 were related to the forest fire database. It was found that there is a relatively weak to moderate correlation between forest fires and the values of the Canadian Forest Fire Weather Index. In order to improve the wildfire risk assessments (including forest fires), the index was modified. The modified index has a significantly greater correlation with the actual events of forest fires and consequently a much wider application in southern Serbia. The modified index can be of great importance in the future concepts of forest fire risk management.
