On Rebun-to Island, a team of administrative bodies and local entities is working together to manage trails. By transmitting unified information on a website after discussing the park rules and levels of difficulty for courses among all interested parties, the efforts have been taken to ensure the conservation of the natural environment and for the safety of users.
As a consequence of human activities such as farmland development and river improvement, the peat lands in the Sarobetsu area are suffering from aridification, causing the loss of vegetation unique to high moors. To that end, with the cooperation of people with relevant knowledge and experiences, administrative bodies and local dairy farmers, a nature restoration project has been implemented aiming to prevent the aridification of wetlands and to restore a post mining site of peat.
