Removal or Retention of Unmerchantable Saplings in Allegheny Hardwoods: Effect on Regeneration after Clearcutting
Abstract:Disposition of residual saplings left after a 1937 clearcutting for chemical wood in a northern hardwood stand in Pennsylvania had a major effect on the development of the new stand. Where these saplings were mowed down (cut), the new stand, after 35 years, is dominated by fast growing, shade-intolerant black cherry. (Prunus serotina Ehrh.) in the overstory whereas the slower growing sugar maple (Acer saccharum Marsh.) and beech (Fagus grandifolia Ehrh.) are relegated to the understory--even though these tolerants were present as advance seedlings before cutting. Where the tolerant species were retained as saplings up to 5 or 6 inches d.b.h. after cutting they are represented in the larger diameters and upper crown strata. Plots with residual saplings have higher average stand diameter and higher basal areas in merchantable-sized trees than plots on which stems over 0.5 inch d.b.h. were mowed.
