“…This effect has also been observed by other authors (Johnson and Curtis 2001). Some studies have shown that the gain in SOC obtained by leaving harvesting residues in the field is stronger in coniferous than in broadleaved species (Hendrickson et al 1989;Johnson and Todd 1998;Knoepp and Swank 1997;Mattson and Swank 1989), although some studies in coniferous forests and in mixed forests have also shown little or no effect of residues on soil C or N (Olsson et al 1996;Johnson et al 2002). The greatest effects on both SS decreases and in BM increases were in E. nitens, probably because of its high yield and crown biomass (Pérez-Cruzado et al 2011a).…”

Although it is known that forestry mitigates carbon emissions to some degree, there is still a need to investigate the extent to which changes in forest management regimes affect the carbon cycle. In a climate-change scenario, forest management schemes must be optimized to maximize product supply and minimize environmental impacts. It is difficult to predict the mitigating effects of different silvicultural regimes because of differences in the growth characteristics of each species, destination of products, and industrial efficiencies. The objective of the present study was to use a modeling approach to evaluate the effects of different management regimes for fast growing species in southern temperate Europe in relation to mitigating climate change. A comprehensive study was carried out considering the C sink effect in biomass, soil and wood products, the substitutive effect of bioenergy, and particular conditions of the forest industry in southern Europe. The mechanistic CO 2 Fix model was parameterized for three species used in fast growing plantations in southern Europe: Eucalyptus globulus, Eucalyptus nitens, and Pinus radiata. Data from 120 plots covering the complete age range observed for each species were used to calculate changes in C stocks in aboveground biomass and organic and mineral soil and to validate the parameterized model for these conditions. Additional information about the efficiency of forest industry processes in the region was also considered. A strong bias in soil organic carbon estimation was observed and attributed to overestimations in the decomposition rates of soil compartments. Slight bias was also observed in the carbon biomass estimation when forest-specific yield models were used to simulate afforestation over former pastureland. As regards the model sensitivity, the Yasso model was strongly robust to turnover of leaves, roots, and branches. The chip wood production alternative yielded higher carbon stock in biomass and products, as well as in bioenergy substitution effect, than the sawn wood production alternative. Nevertheless, the sawn wood alternative was the most effective as regards the C stock in the soil. Site index had an important effect for all species, alternatives, and compartments, and mitigating effects increased with site index. Harvesting of clearcutting and thinning slash for bioenergy use led to a slight decrease in the soil carbon equilibrium but significantly increased the mitigation effect through bioenergy use.

“…Various studies have shown a significant influence of tree species selection and accompanied forest stand composition on carbon stocks (LadegaardPedersen et al 2005;Prietzel & Bachmann 2012). Forest management practices such as drainage, thinning, timber harvesting and liming can also affect soil carbon dynamics (Johnson et al 2002;Nave et al 2010). Admittedly, investigations of liming induced effects on carbon stock changes have revealed contradictory results.…”

Close to one third of Germany is forested. Forests are able to store significant quantities of carbon (C) in the biomass and in the soil. Coordinated by the Thünen Institute, the German National Forest Inventory (NFI) and the National Forest Soil Inventory (NFSI) have generated data to estimate the carbon storage capacity of forests. The second NFI started in 2002 and had been repeated in 2012. The reporting time for the NFSI was 1990 to 2006. Living forest biomass, deadwood, litter and soils up to a depth of 90 cm have stored 2500 t of carbon within the reporting time. Over all 224 t C ha -1 in aboveground and belowground biomass, deadwood and soil are stored in forests. Specifically, 46% stored in above-ground and below-ground biomass, 1% in dead wood and 53% in the organic layer together with soil up to 90 cm. Carbon stocks in mineral soils up to 30 cm mineral soil increase about 0.4 t C ha -1 yr -1 stocks between the inventories while the carbon pool in the organic layers declined slightly. In the living biomass carbon stocks increased about 1.0 t C ha -1 yr -1. In Germany, approximately 58 mill. tonnes of CO 2 were sequestered in 2012 (NIR 2017).

“…Mendham et al (2003) found that soil organic C decreased mostly in the first 10 years after intervention. While tree harvesting may cause short-term losses in soil organic C (Laiho et al, 2003), negative long-term effects on soil organic C storage were not detected (Johnson et al, 2002;McLaughlin and Phillipps, 2006). Finally, in the study of Kaarakka et al (2014), 10 years after the final whole-tree harvest it was evident that repeated whole tree harvest had a decreasing effect on total C and N pools.…”

“…In addition, the removal of whole trees caused shortterm losses of soil C (Johnson and Curtis, 2001;Laiho et al, 2003). However, long-term effects of harvesting on soil organic C storage were not detected (Johnson et al, 2002;McLaughlin and Phillips, 2006).…”

“…Forest management practices, forest vegetation and fires, as well as other physical disasters played a crucial role in soil erosion, thus in the balance of organic carbon (Johnson et al, 2002;Lal, 2005;MataixSolera et al, 2011;Cerda et al, 2017;Pereira et al, 2017). Depending on silvicultural management practices and on the methods of collection of forest products, soils were positively or negatively influenced by C accumulation or decrease, respectively (Laiho et al, 2003;Peltoniemi et al, 2004;McLaughlin and Phillips, 2006).…”

After forest harvesting, organic matter accumulation and soil nutrient availability are usually negatively influenced, especially during the first years. The hypothesis that 15 years after selective harvesting (15Y) the increased forest biomass, together with the enhanced nutrient recycling rates, compared to 5-years after harvesting (5Y), could restore nutrient availability and organic C accumulation (both in forest floor and soil) to similar levels to the intact site, was tested. The aim of this study was to investigate the effect of the timing of management practices (intact forest-control, 5Y, 15Y) on organic matter content, nutrient concentrations in needles, forest floor and soil, in a forest ecosystem of Picea abies L., in Rodopi mountainous area, in northern Greece. Significant differences between the intact site and the other two treatments were found in: i) soil N, P, C/N and exchangeable Ca, ii) organic matter and nutrient accumulation (basically in the upper 30 cm), iii) foliar K, Fe and Zn concentrations. In conclusion: i) forest management practices clearly influenced soil fertility and organic matter accumulation, ii) 15 years after selective harvesting nutrient and organic C accumulation in forest floor, as well as K and Fe accumulation in soil were restored to similar levels to the intact sites; thus, our hypothesis was partially correct.
