Abstract (2. Language):
Forest roads provide access to forest resources in order to conduct forest operations and to extract all types of
forest products economically. Forest roads should be well planned in such a way that damages on the forest
ecosystem are minimized. The landslides, caused by the natural or man-induced complex environmental factors,
are considered as one of the major environmental impacts along the forest roads. Some soil properties may
weaken the cohesion of the soil and accelerate the road disruptions. In this study, causes of the landslides that
happen on the forest roads in Maçka Region in northeast of Turkey have been investigated in terms of the soil
properties. For this purpose, soil samples were collected separately from the sample fields (SF) subject to
landslides and from the areas of control points (CP) with no landslide occurrences. Dispersion rates (DR)
indicating the sensitivity of the soil samples to erosion, and their physical and chemical properties have been
investigated. The results indicated that most of the landslides along the roadway occurred on the cut slopes. As a
result of soil analysis, the soils of entire study area were found to be sensitive to erosion (DR > 15) and the soil
type was generally in the sandy clay form. It was found that there was negative and meaningful correlation
between DR and Fe along with Silt, while there was a meaningful and positive correlation between DR and
Sand. In order to find out whether SF and CP are different in terms of soil properties, Independent Sample T-test
was conducted. The results revealed that there was a significant difference only in P (Phosphorus) content while
the differences between other soil properties were found to be insignificant.
