months of July, August and September in the area of Negotin and Zaječar. Surface fire only (20≤B≤ 39) is possible in the period March-April in the area of Negotin and Zaječar. During the period December-February, the occurrence of fires is unlikely in the area of Crni Vrh. Table 6 shows a significantly higher value of the burning index in 2012 compared to 2014 at all stations. The correlation between the value of the burning index and the number of forest fires in 2012 is shown in Figure 4. It is noted that there is a connection between the value of the burning index and the occurrence of forest fires in the observed period. For the region of northeastern Serbia, the correlation is of medium intensity (r = 0.48; R2 = 0.23), but it is not statistically significant (p> 0.05). The results of this study confirm the findings (Živanović, 2017; Tošić et al., 2019; Živanović et al., 2020; Tošić et al., 2020) that there is a coincidence of the largest number of fires in nature in Serbia with periods with high air temperatures and daily and monthly reduced moisture content in soil and fuel material. Ćurić and Živanović (2013) and Živanović (2020) pointed out that there is connection between the dynamics of fire occurrence and the distribution and amount of atmospheric precipitation. Several studies have found that summer droughts and high temperatures are the primary determinant of interannual fire variability in Southern Europe (Turco et al., 2013; Pereira et al., 2013; Turco et al., 2017). Koutsias et al. (2013) state that fire occurrence in the eastern Mediterranean region is |
