diversity (P>0.05), but a significant change in plant diversity in observation periods was registered (P<0.05). The highest taxa diversity was measured in June (2.53), while the lowest diversity was measured in September (2.33) (Figure 4). It was also determined that the stand type-aspect interaction had a significant effect on diversity (P<0.05). According to the Shannon diversity index, the highest diversity was measured in the GC stands with 2.65 on the south aspect and the lowest diversity was measured in the GB stands on the south aspect with 2.15 (Table 8). When the fir stands were examined in terms of evenness values, it was determined that the stand type, aspect and observation period did not have a significant effect on the homogeneous distribution of the plants in the area (P>0.05). In addition to this, the interactions did not affect the species distribution (P>0.05). Findings of Gamma Diversity – Rezultati gamma raznolikosti The indices in this section, which represent larger populations (e.g, fir stands on south aspects), represent gamma diversity. Therefore, large regions were evaluated as the sampling area, and the species and numbers belonging to this area were evaluated together. While calculating the diversity indices of the GA stands, the taxa and numbers of 4 (observation time) *2 (aspect)*10 (quadrate)*2 (repetition) =160 quadrate samples were evaluated together. Also, the other stands were evaluated similarly. In the study, a total of 122 taxa were determined in fir stands. Gamma diversity in fir stands is 0.96 according to the Simpson index and 3.64 according to the Shannon index. In terms of gamma diversity, the lowest Simpson index was measured as 0.93 in the GB stands and the highest as 0.96 in the GC stands. While the average Shannon diversity index value was 3.41, the lowest value was determined in GB stands with 3.21 and the highest was determined in GC stands with 3.57 (Table 9). While the highest number of taxa was observed in July with 82, the lowest number was seen in September with 54. In terms of observation period, the highest diversity according to the Shannon index for fir stands was in June (3.51), and this decreased gradually towards August and started to rise again in September (3.31). The Simpson diversity index shows a similar trend to the Shannon index (Table 10). The number of taxa and individuals were higher on the south aspects. Shannon diversity index values were also higher in the south than in the north. The Shannon value was 3.59 on the south aspect and 3.58 on the north aspect, while the Simpson diversity index values were determined as 0.96 for both aspects (Table 11). When the stand type-observation period interaction was examined, the highest diversity according to the Shannon index was observed in July and September in GC stands with a value of 3.22. The lowest value of 2.62 was observed in GB stands in August. According to the Simpson diversity index, the highest value of 0.95 was observed in GA stands in July and in GC stands in September. The lowest value of 0.89 was observed in GD stands in August. Evenness values ranged between 0.40 and 0.68 (Table 12). According to the Shannon index, the highest diversity was observed in GC stands with a value of 3.41 on the south aspect. The lowest value, with 2.73, was observed in the GB stands again on the south aspect. Only for this stand type, |
