The reverse-J shaped curve, and specific versions of it, have become synonymous with unevenaged silviculture in American practice. It has its role, but there are other alternatives. It is important to understand the goals of silviculture and the biological assumptions behind the use of a reverse-J curves, before using them to develop practical marking guides. At the same time, it is important f...
The history of forest management in the southern United States has been a process of intensification and the pine forests of the Coastal Plain can be regarded as in the early stage of crop domestication. Silviculture research into tree improvement and other aspects of plantation establishment and management has been critical to the domestication process, which began in the early 1950s with the ...
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...
