TY - JOUR T1 - Evaluation of Forest Road Networks Located in Karadeniz Technical University Research and Practice Forest AU - Gumus, Selcuk PY - 2015 DA - June JF - European Journal of Forest Engineering JO - Eur J Forest Eng PB - Forest Engineering and Technologies Platform WT - DergiPark SN - 2149-5637 SP - 15 EP - 20 VL - 1 IS - 1 LA - en AB - Forestroads are in mutual interaction with many factors such as technical, economicand environmental requirements. The evaluation of forest roads network has beenclarified by considering issues such as the accessibility to forest, the costof transportation and impact on the environment. In this study, evaluation offuture usage of existing forest roads have been aimed with taken into accountto all tasks in accordance with the sustainable forestry objectives. To reachthis goal, previously developed forest road evaluation and grading method wastested in Karadeniz Technical University (KTU) Research and Practice Forest.The total road length in the study area was 107+371 km which contained 27 roadsegments. All forest roads in the study area were classified into four qualityclasses (Class I: very good; Class II: good; Class III: bad; Class IV: verybad) for the future use. After evaluating the forest road network, it was foundthat 50.51% of the road was classified as Class II, while 31.09% and 18.39%were classified as Class I and Class III, respectively. The results indicatedthat there was no road segment under Class IV. The results suggested that theforest road network of the KTU Research and Practice Forest was sufficient ingeneral regarding with the sustainable forestry goals. However, about 20% ofthe road was found to be in bad quality status. It can be concluded that it isnecessary to implement urgent road repair in these segments based on forestroad evaluation and grading method. Thus, it would be very useful to implementthe road evaluation process described in this study in redesigning stage offorest road networks.
