REZULTATI
In this study, the tree properties exhibited high variation. RCD of saplings varied from 1 cm to 5 cm, while H of RCD saplings varied from 1,25 m to 1,65 m . DBH varied from 1,5 cm to 42 cm, while H varied from 1,9 m to 26,7 m. Other descriptive statistics are provided in Table 2. The results of the correlation analysis are shown in Table 3. In general, the crown fuel components were found to be significantly correlated to H, RCD, DBH, CW, and CL. All of the crown fuel components had a strong relationship with CL. According to Table 3, all the crown fuel components had a strong relationship (p=0,01) with all the tree properties.
To develop allometric equations that allow estimating the biomass of crown fuel components, the measured tree properties were used as independent variables in different allometric equations. All allometric relationships identified between the dependent and independent variables are shown in Table 4. Among the different allometric equations, the variation in fine branches was explained the most by CW and CL, which together explained 90% of the variation in this parameter (P<0.001). On the other hand, the variation in very fine branches was explained the least by H, which could only explain 60.4% of the variation (P<0.001). The variation in total fuels was explained the most by CW and CL, which together explained 89.8% of the variation in this parameter (P<0.001). On the other hand, the variation in total fuels was explained the least by H, which could only explain 78.4 % of the variation (P<0.001). The variation in active fuels was explained the most by H, CW, and CL, which together explained 86.8% of the variation (P<0.05). This trio of properties also explained 81.6% of the variation in foliage (P<0.001).
The mean fuel load distribution of the crown fuel components show that thick branches were the most common, representing 31.43% of the components, followed by foliage mass, representing 29.98% of the components. Active fuels constituted 56.6% of the total crown biomass (Figure 2). The relationship between by DBH estimated and actual
