MODELING DIAMETER DISTRIBUTION OF LOBLOLLY PINE PLANTATIONS IN RESPONSE TO MID-ROTATION THINNING TREATMENTS AND ASSING THE ECONOMIC RETURNS IN WESTERN GULF COASTAL PLAIN
<p>The influence of thinning regimes incorporating row thinning on diameter distribution and timber product allocation is of considerable importance in the management of loblolly pine (<em>Pinus taeda</em>) plantations within the Western Gulf Coastal Plain. This study utilized data from a thinning …

Modeling General Response to Silvicultural Treatments in Loblolly Pine Stands
… functions/multipliers accounting for effects of thinning, fertilization, and control of competing vegetation. Chapman-Richards functions were used to model the base-line growth. Separate response functions to mid-rotation thinning and fertilization effects were developed. The thinning response …

Growth Models and Mortality Functions for Unthinned and Thinned Loblolly Pine Plantations
Effects of thinning, such as increased diameter growth and decreased mortality in the residual stand, have been recognized by foresters for many years. These effects are largely the result of increased tree vigor which is induced by a decreased level of competition. These relationships are …

Predicting height to live crown increment for thinned and unthinned loblolly pine plantations
… for competition. Hypothesis tests revealed that thinning, both its intensity and the elapsed time since its occurrence, had a significant effect on crown height increment. A thinning variable, THIN1, which accounted for thinning intensity and the interval since thinning, was developed and …

Dynamic modeling of branches and knot formation in loblolly pine (Pinus taeda L.) trees
… to evaluate the effect of initial spacing and thinning intensity on branch growth in sawtimber trees. The use of the dynamic branch model permitted generation of additional information on sawlog quality under different management regimes. The arithmetic mean diameter of the largest four …

Stand Density Management for Optimal Volume Production
… design and other pitfalls. Using data from two thinning studies representing non-intensively and intensively managed plantations, one spacing trial, and one thinning experiment a comprehensive analysis was performed to examine the growth-density relationship in loblolly pine. Volume production …

The impact of silvicultural strategies and climate change on carbon sequestration and other forest ecosystem functions
… a management strategy with an intermediate thinning intensity and a high share of pine stands to enhance income from timber production while maintaining the other forest functions. The analysis served as an example for the combined application of simulation tools and a MCA method for the …

Einfluss der Bewirtschaftungsintensität auf die Wachstumsdynamik von Waldmeister-Buchenwäldern (Galio odorati-Fagetum)
In der vorliegenden Studie wird anhand detaillierter Analysen zur Wachstumsdynamik von Waldmeister-Buchenwäldern (Galio odorati-Fagetum) ein Beitrag zur aktuellen Debatte um den Schutz und die Nutzung von Buchenwäldern in Norddeutschland geleistet. Dabei wurde der Frage nachgegangen, inwieweit …
