Description :
New Zealand research relating to erosion impacts of plantation forest roads, tracks and landings has been carried out since the mid-1970s. Methods include paired catchments studies, storm-induced mass movement surveys, and surface erosion plot experiments from both natural and simulated rainfall-runoff. Road surface erosion data exist only for indurated conglomerate, granitic, schist and pumice terrains. Young roads tend to have greater landslide susceptibility. Despite predicted increases in sediment yields from road surfaces during forest establishment and harvesting activities, annual sediment yields from catchments appear to be within natural levels.
