• Perhaps the major problem with such a soil conservation strategy is that it requires con-
tinuous, sensitive, timely and knowledgeable management of the soil and vegetation
and the use of appropriate and cost effective erosion control techniques and material to
be fully effective. But the rewards in terms of reduced soil loss and potential dollar
savings are indisputable. One must keep in mine, however, that regardless of soil con-
servation planning and implementation efforts to stabilize post mine drainageways,
their long term stability and that of adjacent undisturbed drainages is subject to the
affects of catastrophic weather patterns.
