Oak-Hardwood Reproduction in Central Pennsylvania
Advanced reproduction in a relatively undisturbed, 55-year-old, oak-hardwood stand amounted to more than 12,000 seedlings and seedling sprouts per acre. Additions and conversions over a two-year period were analyzed by species, age, origin, and size on replicated plots. Clearcutting was most favorable for aspen establishment, the only very-intolerant, light-seeded species in the original stand. Stand removal intensity did not appreciably influence establishment of oak, red maple, and black cherry. Conversion to seedling sprouts was primarily attributed to microclimatic changes on logged areas rather than to mechanical injury. Height growth of reproduction was greatest on the clearcut plots.
