Introduction and Objective: Almost all activities of forestry plans have stopped due to logging ban and lacking funds. In the meantime, the repair and maintenance operation of forest roads, which is required every year, has been interrupted and many visible damages have been occured. The amount, form and upcomming damage is a very important issue in forest management. Since the investigation and statistics of forest roads during the implementation of the logging ban has been less investigated, this study seeks to investigate the impact of that on the protection and maintenance of forest roads. The purpose of this study is identify and locate damaged areas in the forest roads.
materials and methods: In this project, with a ground survey of all forest roads in Neka and Behshahr counties, with a length of 336.68 km and with a point-by-point survey of damages by GPS, in the form of full inventory and based on the damage tables, the current situation is investigated and the possibility of decision-making by managers prepared based on correct statistics.
Results: According to the results, along the roads, a total of 1056 cases of damage including; 121 cases of cut slope sliding, 48 cases of fill slope sliding, 74 cases of road basement sliding, 167 cases of speed-limiting potholes, 280 cases of ditch blockage, 116 cases of culvert blockage, 67 cases of culvert destruction and 140 cases of crossing barriers by fallen trees occurred. In Behshahr, damage to the Main access roads, Main roads and Secondary roads were 83, 58 and 22 cases respectively. In Neka, the damage were included 108 cases of damage on Main access roads, 469 cases on Main roads, and 303 cases on Secondary roads. In Neka, Main roads, Secondary roads, and Main access roads have received the most damage respectively.
Conclusion: Therefore, in Behshahr, the most damage occurred to the Main access roads, and in Neka, the most damage occurred on the Main roads. The observed problems indicate the non-implementation of road protection and maintenance operations during the period of logging ban.
