Description :
A series of 75 non-bordered plots was used to measure surface erosion on granitic road cuts on forest roads in the mountains of Idaho. Erosion data were collected for 4 years following road construction. Both mass and surface erosion processes were observed on road cuts. Regression analysis showed slope gradient, slope aspect, ground cover density and snow-free period rainfall erosivity had statistically significant effects on erosion. Slope gradient was the most influential site factor affecting erosion. Three erosion control treatments : dry seeding, hydroseeding plus mulch, terracing with hydroseeding plus mulch, were evaluated.
