and nearly flat land. Slope is one of the most important factors in determining the method of extraction of logs from a compartment (Bayoğlu, 1996; Garland, 1997; Erdaş et al., 2014). For this reason, a slope map of the study area is shown in Figure 4. According to this, 41.79% (3472 ha) of the total study area of 8308 ha is suitable (slope 0-33%) for extraction work using agricultural tractors.
Existing skid trail findings – Utvrđivanje postojećih traktorskih vlaka
The skid trails of the compartments in the study area were measured to determine the extent of the area they covered. The average slope ranges of the skid trails was recorded 0-33% in the compartments. According to the findings obtained from the skid trails in compartment No. 85, the average trail width was 2.72 m and the average length was 308 m. The hectare density and coverage areas of the skid trails were found to be 108 m / ha and 293 m2 / ha, respectively. In addition, a total of 22 skid trails were found in the compartment, with the shortest being 120 m in length, while the longest was about 700 m long.
According to the findings, the average width of the skid trails in compartment No. 86 was 2.97 m and the average length was 320 m. The densities and coverage areas of the skid trails in the compartment were determined to be 125 m / ha and 370 m2 / ha, respectively. In addition, there were a total of 23 skid trails in the compartment, with the shortest having a length of 60 m and the longest a length of approximately 1100 m.
Amount of runoff and suspended sediment – Količina otjecanja i suspendiranog nanosa
Measurements during the period of September 2014‒March 2016 were assessed by taking the nine plot measurements. The average runoff rates in the test site plots were 6.32 mm / m2 in the control plots, 6.13 mm / m2 in the wood chips plots and 6.03 mm / m2 in the slash plots.
In the period covering runoff from the plots, the total sediment transported and the amounts of suspended sediment transported from the sample field plots are given in Table 2. The amount of sediment was found to be 2.58 g m-2 in the control plots, 1.61 g m-2 in the wood chips plots and 2.13 g m-2 in the slash plots. An annual average of 16.61 g m-2 year-1of soil loss was found in the control plots. Şensoy and Kara (2013) carried out a study within the boundaries of a village and the average amount of suspended sediment transported annually from the unit on the long plot was determined as 809.68 g m-2 and 766.53 g m-2 on the short plot. These values were high because the slope was between 25-30% and the plots were not in a closed stand.
In the study area, the hectare density and coverage areas of the skid trails were determined as 117 m/ha and
