Harvest systems consisting of farm tractors and skidders are the most popular systems for timber harvesting in Turkish forestry. The modified farm tractors are used in many regions in Turkey. In many regions of the world, farm tractors have been used in forestry where the terrain conditions and the size of the forest operation are not limiting. The modified farm tractors are used generally on skid roads and skid trails inside harvesting area. The skid roads are constructed in a simple way. For skid trails, gaps in the forest are used. Logging is perceived to be one of the major causes of damage to forest vegetation. The planning operations for wood extraction require careful consideration not only to minimize cost but also to reduce the negative impacts on forest soil and trees inside stands. Especially, damages on forest soils occur during skidding of timber. The types of damages on soils are traces, erosion and splitting. Soil erosion can occur in damaged area in next years. The skidding operations with tractors and transporting operations with cable systems can be given trees and saplings in stand. This damages type on trees and saplings is generally in the form of bark injury. Study area is managed by Bahcekoy Forest Administration and this area was located in northern Turkey. The study area is a black pine (Pinus nigra) stand. In this study, the farm tractors were used to different shapes as skidder, loader and tractor trailer. Environmental impacts of skidding operations and loading operations were investigated in harvesting area and on the skid roads. The types of damage were determined during the harvesting and transporting operations.
