Many, but not all, trees comprising advance regeneration are potential crop trees. Observations that advance regeneration responded to release appear repeatedly in the field notes, and there is independent supporting evidence that advance regeneration will respond to release (Hallin 1959, Helms and Standiford 1985). The stand establishment period can be bypassed and a long step taken into the next rotation if adequate amounts of suitable advance regeneration can be protected during a relatively short conversion period (fig. 17). An arbitrary 10-year reentry cycle does not meet the silvical needs of stands with abundant advance regeneration. Complete removal of scattered overstory is desirable in the first cut when an area is already adequately stocked. Felling and skidding direction should be controlled to minimize damage during removal of overstory from regeneration thickets where it no longer serves a useful purpose. To accomplish this on the steeper slopes without inflicting excessive damage to the regeneration is a real challenge. But that challenge must be met sooner or later during use of the shelterwood system. So the learning process might as well start right away on areas already adequately stocked. 52
