Yield 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 کاملEven-Aged vs. Uneven-Aged Silviculture: Implications for Multifunctional Management of Southern Pine Ecosystems
We evaluated evenand uneven-aged silvicultural options for slash pine (Pinus elliottii Engelm.) using empirical data and the Forest Vegetation Simulator (FVS) model. Data were collected from a mature unthinned slash pine plantation in a flatwoods site in Florida, and used to simulate six scenarios of evenand uneven-aged silvicultural regimes applied to slash pine stands, including a no-action o...
متن کاملOptimal Management of Naturally Regenerating Uneven-aged Forests
A shift from even-aged forest management to uneven-aged management practices leads to a problem rather different from the existing straightforward practice that follows a rotation cycle of artificial regeneration, thinning of inferior trees and a clearcut. A lack of realistic models and methods suggesting how to manage uneven-aged stands in a way that is economically viable and ecologically sus...
متن کاملComparing the effects of even‐ and uneven‐aged silviculture on ecological diversity and processes: A review
With an increasing pressure on forested landscapes, conservation areas may fail to maintain biodiversity if they are not supported by the surrounding managed forest matrix. Worldwide, forests are managed by one of two broad approaches-even- and uneven-aged silviculture. In recent decades, there has been rising public pressure against the systematic use of even-aged silviculture (especially clea...
