Assessment of ground-based skidding impacts on the horizontally rate and extent of soil disturbance along the margin of the skid trail

Table 2 Characteristic of sampling plot locations

Block no.	Gradient (%) of block	Block order	Traffic (passes)	Length of block (m)	Elevation (m)
1	19.0	2	40	20.0	878.0
2	6.0	1	40	18.0	886.0
3	29.0	3	40	28.6	906.8
4	16.0	2	20	34.8	915.7
5	27.0	3	20	26.2	947.0
6	9.0	1	20	17.8	971.3

The plots were located at different levels of traffic and slopes on the skid trail. Three slope gradients were present for each traffic intensity segment of each skid trail: gentle slopes in which the slope gradient of the skid trail was between 0 and 10 %, moderate slope was between 10 and 20 % and steep slopes in which the gradient exceeded 20 %
