Identifying unstable sites on logging roads

Abstract

Logging roads are an important source of forestry-related erosion. The amount of erosion on a forest road is determined by the interaction between how the road is constructed and maintained and the environment in which it is built. The roads in this study were constructed with large bulldozers, and most excavated material was sidecast. The roads studied were constructed primarily for trucks transporting logs. They averaged 11.5 years old. Available running surface averaged 5 m wide, ranging from 3 m to 9 m. About 68% of the roads were surfaced with crushed rock, 15% were unsurfaced, and 17% were paved with asphalt. The average road gradient was 4°, but some short segments were as steep as 9°
