Abstract Broad-scale estimates of coarse woody debris (CWD) yield across landscapes are somewhat rare, despite the importance of CWD in ecosystem functioning and its potential role in terrestrial carbon cycles. Yields of CWD were estimated at regional scales by linking a stand-level predictive model with regional forest inventory data for 11 states in the southern United States. We estimated that the accumulation of CWD in late-rotation loblolly pine plantations across the South totals 48.67 million metric tons of dry wood necromass, the carbon equivalent of 24.33 million metric tons. This represents annual CO2 emissions of 21 coal-fired power plants, or the amount of carbon sequestered each year in 7 million ha of pine forests. Confidence intervals for CWD dry weight per hectare generally did not exceed ±25% of the estimated values. Although county-level estimates were of higher uncertainty, the spatial pattern appeared to be relatively consistent with the extent of loblolly pine, with low yields near the extremes of the species' natural range and high yields in extensively forested portions of its range. Quantifying regional carbon stores of CWD with respect to stand-level management activities may improve accuracy of regional estimates and provide further insight into management effects on the carbon pool and the carbon cycle.

Biomass procured from forests affected by natural disturbances as a bioenergy source is increasingly considered in the context of climate change mitigation. By comparing clearcuts with and without biomass procurement, we aimed to determine the effects of biomass extraction performed alongside lumber harvesting on regeneration density, number of planting microsites, forest renewal costs, and carbon fluxes, in harvested boreal stands affected by spruce budworm. Results showed that biomass procurement increased regeneration density and number of planting microsites. Reduction of downed woody debris due to biomass procurement lowered site preparation costs by 282.07 CAD•ha-1, equivalent to 14.45 CAD per oven-dry metric tonne (odmt-1) of harvested biomass. Product value from biomass processing had to reach from 13.90–76.84 CAD•odmt-1 to make biomass procurement operations profitable. Since biomass procurement significantly increased stocking and reduced the amount of decaying debris, it also reduced cumulative CO2 emissions relative to scenarios without biomass procurement. However, ensuring forest renewal through site preparation and plantation per se, irrespective of biomass procurement, played a more important role for carbon sequestration and net balance. Integrating biomass harvesting to silviculture could have significant ecological and financial impacts on forest management while supporting mitigation efforts against climate change.

Abstract To evaluate site preparation effects on loblolly pine five years after stand establishment in east Texas, trees/acre, d.b.h., total height. and total biomass were measured on four treatments: clear-fell, burn, chop and burn, and shear/pile and disk. Treatment effects on production were not statistically significant (α = 0.1), but two points were evident: (1) more intensively prepared sites had better stem distributions, and (2) the height variation component due to soil was larger than the treatment component. Bulk densities indicated no significant compaction; soil chemical properties for the mechanical treatments were similar to the clear-fell treatment. Foliar and stemwood Ca, Mg, K, P, N were similar for all treatments. Adverse effects of the mechanical methods on site productivity were not evident when compared to the clear-fell treatment.

Abstract Wet-weather harvesting operations on wet pine fiats can cause soil disturbances that may reduce long-term site productivity. Site preparation and fertilization are often recommended as ameliorative practices for such disturbances, but few studies have actually quantified their effects on restoration. The purposes of this study were to quantify the effects of wet-weather harvest traffic in designated skid trails on soil properties and loblolly pine (Pinus taeda) growth, and to evaluate the ameliorative effects of site preparation. Study sites were established on wet pine flats of the lower Coastal Plain within the Francis Marion National Forest (Berkeley County, SC). Treatments were arranged in a split-split plot within a randomized complete block design. Treatments were two levels of traffic (nontrafficked, trafficked), four levels of mechanical site preparation (none, disking, bedding, disking + bedding), and two levels of fertilization (none, 337 kg /ha of 10-10-10 fertilizer). initially, the trafficking increased soil bulk densities and reduced soil water movement and subsequent growth of loblolly pine (years 1 and 2). Bedding combined with fertilization restored site productivity to non trafficked levels within 4 yr, but disking or fertilization treatments alone were not effective at ameliorating the traffic effects. The effectiveness of the bedding and fertilization treatments for amelioration of traffic effects was probably facilitated by the relatively small area of disturbed skid trails (<10%) found on these sites. Areas having more severe disturbance or higher percentages of disturbance might not be ameliorated as rapidly. South. J. Appl. For. 22(4):222-226.
