title: Physical effects of vehicular disturbances on arid landscapes.
abstract: Field experiments indicate that the use of off-road vehicles on arid land increases the amount and frequency of water runoff and erosion by decreasing soil porosity, infiltration capacity, effectiveness of surface stabilizers, and hydraulic resistance to overland flow. These effects are long-lived and may result even when the use of these vehicles is slight.
