EFFECTS OF OFF-ROAD VEHICLE USE ON THE HYDROLOGY AND LANDSCAPE OF ARID ENVIRONMENTS IN CENTRAL AND SOUTHERN CALIFORNIA

At Panoche Hills in central California, an area formerly used by motorcycles together with an adjacent unused area were monitored from 1971 to 1975. At Dove Spring Canyon in southern California, erosion was measured on a site that is currently being used for motorcycle hill climbing. At the Panoche Hills site, the area used by motorcycles produced about eight times as much runoff as the unused area. Similarly, sediment yield from the used area was 857 cu m/sq km while the quantity of sediment from the unused area was not measurable by standard survey methods. At the Dove Spring Canyon site, which is still being used for hill climbing, erosion surveys show that degradation in trails has been as much as 0.3 m in the period 1973-1975. Compaction of soils and reduction of permeability appears to be the most serious hydrologic impact of motorcycle use at Panoche Hills.
