Abstract

The effect on residual tree growth 5 yr after soil rutting caused by a mechanized thinning system operating during wet soil conditions was examined in a natural loblolly pine stand. No significant differences were observed when the physical characteristics of the surface 2 in. of sandy loam soil on skidding corridors and untrafficked areas were compared. Diameter growth in the 0-6 ft zone adjacent to corridors was significantly better than the growth observed in the >12 ft zone, but comparisons of other tree characteristics were not significant. Although not recommended, shallow rutting of corridors when soil conditions are wet may not necessarily be detrimental to overall site productivity in spite of the visual impressions immediately after harvesting.
