Forest road building and timber harvesting were recognized as principal causes of forest soil degradation, resulting in accelerated soil erosion, the removal of surface soil horizons, and increased soil densities which may result in a reduction of the productive capability of a site. The use of a green fallow as part of site rehabilitation measures was tested on a coastal forest soil that had been subject to accelerated erosion and on an interior forest soil that had been subject to landing construction. This report presents the results of these two studies, as well as a bibliography on regeneration.
