Vegetation on contour slows hillslope soil loss after forest clearing
Planting or retaining grass strips, hedgerows, and trees along elevation contours breaks runoff into slower sheets, trap sediment, and reduce rill and gully growth on freshly exposed slopes.
The method copies how natural understory once interrupted raindrop energy and surface flow. Alone it cannot replace deep forest roots, yet it measurably cuts the pulse of soil leaving a cleared hillside.
Restoration often starts with geometry. Contour vegetation turns a sliding slope back into a staircase that holds earth while trees reestablish.
