||Jozankei National Forest, a part of the Shikotsu Toya National Park, is located in a mountainous area about 30 km south of central Sapporo. The forest is managed by selective cutting based on highdensity forest road network. Because of the roads, visitor access is easier than it is in other surrounding forests. From spring to autumn in 2003, visitor flows were monitored at two entrances of the forest road network using Trail Traffic Counter. There was a remarkable visitor concentration in spring and the behaviour of visitor varied at each season. It was considered that the reason for the difference could be the different purposes of visits to the park as well as the characteristics of the forests visited.
