The action and reaction of the forest road in the Hyrcanian Forest ecosystem, Iran

Managing Hyrcanian Forests in Iran requires a well-designed and constructed network of roads that are appropriately distributed and aligned with the silviculture method. These roads enable access to protection, support, and tourism activities, as well as facilitate the execution of all necessary measures. Around 10,000 kilometers of roads have been built in Iranian forestry projects. Constructing roads in forests has both positive and negative consequences on nature and its natural functioning, including impacts on biodiversity, grass and plant cover, and physical and chemical soil properties. The design and construction of these structures should adhere to the principles and technical-engineering standards of forestry to minimize adverse reactions. To ensure compliance with road construction technical instructions (Publications 131 and 148 of the technical deputy in the Management and Planning Organization of Iran), it is recommended that the Natural Resources and Watershed Management Organization of Iran supervise their implementation in all forest areas, alongside forestry plans. Furthermore, the organization should increase its direct supervision of the country's entire natural resource field to improve project outcomes.
