Attributes of Successionally Stable Even-aged Oak Stands
INTRODUCTION Oak-dominated forests of the Central and Eastern United States have generally not been regarded as suited to uneven-aged silviculture (Roach and Gingrich 1968, Sander and Clark 1971). In fact, several attempts to apply the selection method of reproduction cutting in oak-dominated stands have resulted in compositional shifts toward more shade tolerant species (Trimble 1970). Given t...
متن کاملYield Comparisons from Even-Aged and Uneven-Aged Loblolly-Shortleaf Pine Stands
Empirical yields for a 36year management period are presented for seven long-term studies on similar sites in loblolly-shortleaf pine (Pinus taeda L.-P. 1 The authors thank George Switzer of Mississippi State University, Terry Clason of Louisiana State Uni\'ersity, and Dick Kennedy of Georgia-Pacific Corporation for reviewing the manuscript. Special thanks also to Georgia-Pacific Corporation an...
متن کاملComparison of Log Quality from Even-Aged and Uneven-Aged Loblolly Pine Stands in South Arkansas
Log grade, number of knots, and log volume of the first two logs, as well as form class of the butt log, were compared across three broad sawtimber categories among even-aged plantations, even-aged natural stands, and uneven-aged natural stayMs of loblolly pine (Pinus taeda L.) in Ashley County, AR. Trees from unevenaged stands had butt logs of better log grade than even-aged plantations, parti...
متن کاملLong-Term Susceptibility of Even- and Uneven-Aged Northern Hardwood Stands to Partial Windthrow
While uneven-aged silviculture may appear preferable to even-aged silviculture in terms of stand susceptibility to windthrow (major wind damage), the scientific evidence is equivocal on this issue, because the two systems do not operate over the same time frame. The goal of this study was to evaluate the windthrow susceptibility of evenand uneven-aged stands over a 100-year period. Susceptibili...
متن کاملPotential Yield, Return, and Tree Diversity of Managed, Uneven-aged Douglas-Fir Stands
The effects of different management regimes on uneven-aged Douglas-fir stands in the Pacific Northwest of the United States were predicted with a simulation model. Management alternatives were defined by residual stand structure and cutting cycle. The residual stand structure was set by basal area–diameter-q-ratio (BDq) distributions, diameter-limit cuts (assuming concurrent stand improvement),...
