Landslides and Roads
§ Of all forest land uses, roads, on a per unit-area
basis, are the largest contributor to landslides
(Sidle et al. 1985)
§ Forest landslide impacts include
l Safety
People
Structures
l Increased erosional processes
l Increased delivery of sediment into streams
Loss of aquatic habitat
§ A decision support system for transportation
planning that can take landslide prone terrain into
account could help forest managers
