Due to high fire hazard and perceived reductions in forest health, thinning of small diameter trees has become a prevalent management activity particularly in dense stands. Creation of large amounts of logging slash, however, has created large quantities of habitat for bark beetles primarily in the Ips genus (Coleoptera: Curculionidae, Scolytinae). Evidence indicates that prior to Euro-American...

Incorporation of forest slash during stand establishment is proposed as ameans of increasing soil carbon and nutrient stocks. If effective, the increased soil carbon and nutrient status may result in increased aboveground tree growth. Eight years after study installation, the impact of forest slash incorporation into the soil on soil carbon and nutrient stocks, foliar nutrients and loblolly pin...

Rooted stem cuttings of forest trees are increasingly being used around the world to deploy elite genotypes in intensive forest plantations. In 1992, the NCSU Loblolly and Slash Pine Rooted Cutting Program was formed as an industrially sponsored research cooperative. The primary mission of the program is to conduct research to facilitate the operational use of rooted cuttings for the pines of t...

Moran's I statistic measures the spatial autocorrelation i a random variable measured at discrete locations in space. Permutation procedures test the null hypothesis that the observed Moran's I value is no greater than that expected by chance. The spatial autocorrelation of gross basal area increment is analyzed for undisturbed, naturally regenerated stands in three Georgia forest ypes: 1obloll...

There has been increasing interest in managing forest stands as uneven-aged structures to promote sustainable harvests as well as maintain ecosystem services. This study provides a framework for simulating conversion of mature even-aged stands to uneven-aged slash pine (Pinus elliottii Engelm.) stands using the USDA Forest Vegetation Simulator (FVS) model. A total of 73 scenarios, representing ...

Leaf area index (LAI), needlefall (NF), and forest floor (FF) dynamics are tightly linked with stand productivity, nutrient cycling, and carbon, water, and energy exchange. We analyzed a long-term data set to quantify the impacts of stand development, site quality, and silviculture on LAI and litterfall (LF) in loblolly and slash pine plantations. LAI was significantly correlated with stand den...

Pine engraver, Ips pini (Say), often use thinning slash, and their populations are known to be influenced by the condition of this material. In our study, we evaluated the importance of three log diameters (5, 10, and 20 cm) and three lengths (60,120, and 240 cm) on various parameters of bark beetle host attack, development, and emergence. Evaluation of slash colonization in northern Arizona (n...

L-band multipolarized (i.e. HH, VV, VH and HV) multiple incidence angle aircraft Synthetic Aperture R~dar data were analyzed in relation to the biomass and other stand parameters (e.g. basal area, dI~me!er at breast hel~h~, tree height, and stand volume) for 35 slash pine plantations. The purpose was to detennme If there are statistIcally significant relationships between slash pine stand bioma...

Healthy forests and enhanced habitat for wildlife is a growing concern among public and policy makers. These concerns have led to substantial interest in promoting various regulatory and voluntary compliance policies to further biodiversity on private forests. These policies, however, might result in additional cost to forestland owners. In this paper, we estimate the opportunity cost of adopti...
