Construction of forest roads creates certain conditions in roadside that this situation has its positive and negative effects. This study was done to evaluate the ecological effects of forest road in Amygdalusscoparia forest reserve in Dehloran, Zarin Abaad. After selecting a suitable location for sampling, three transects in the direction perpendicular to the axis of the road in both sides was selected. Four plots (10×10 m) in each transect which located at distance of 1, 20, 80 and 200 meters from the road, were selected. The distance between transects was 90m. In other to achieve the aim of study, in each plot growth variables such as Collar diameter, Height and Crown of trees as well as Ec, pH, Pb, soil texture, organic carbon and nitrogen were recorded. The results show that the road construction on the tree crowns, only at 1 meter, on the collar diameter at 1 and 20 meter and on the height at 1 and 80 meter distance from the road there were a negative significant (p < 0/05) effect. Also, organic carbon and nitrogen at a distance of one meter from road had a significant (p < 0/05) differences with 20, 80 and 200 meters. However, most of these variables were seen at a distance of 20 meter (1/68%, 0.21% and 8/28 respectively). Ec was reduced and pH was increased with increasing distance from the road, but these differences were not significant. In addition, road construction had not significant effect on the Pb and soil texture. In general, the results of this study approved the effects of forest roads on growth variables such as collar diameter, height and crown of trees and also edaphic variables such as organic carbon and nitrogen.
