DescriptionIn seed-tree cuttings at Challenge Experimental Forest, preliminary data show that as advance-growth stocking (20 inches in d.b.h. or less ) increased from 11 t o 49 square feet, seedling mortality increased from 4 to 32 percent (based on stocked mil-acre plots). A comparable increase in the stocking of seed trees over 20 inches in d .b.h. did not increase mortality.
