“…Apart from acting as a physical barrier, logging residues represent a significant nutrient pool in coniferous forests (Weetman and Webber 1972;Palviainen and Finér 2011) from which nutrients are released (Johansson 1994;Hyvönen et al 2000). Water collected below logging residues on a regeneration area in Finland had higher concentrations of organic N, PO 4 3-, Ca 2+ , Mg 2+ and K + compared to incoming precipitation, while the concentrations of inorganic N generally were of similar magnitude (Wall 2008).…”

Logging residues (LR),i.e. tops, branches, and needles, are increasingly being harvested for energy production in Fennoscandia. These residues are temporarily piled on site awaiting transport. This study was undertaken to investigate effects on the soil and soil-water chemistry below different amounts of LR at two recently harvested coniferous sites in Sweden. Seven treatments were included and the studied amounts of LR ranged from no LR left on the ground to four times the estimated LR amount of the harvested stands. Two treatments included eight times the estimated LR amount of the harvested stands but here the LR were removed after 7 or 20 weeks. Soil-water samples were collected during the first six or seven growing seasons. Effects of treatment were detected in the soil water for 11 chemical variables at the northern site, and for the NO and Cl concentrations at the southern site. The strongest response was generally found in the treatment with four times the estimated LR amount, for which the highest concentrations were recorded in most cases. In the first three seasons, the water flux through the LR decreased with an increasing amount of residue. Effects on the exchangeable store of Ca in the mor layer and the upper 20 cm of the mineral soil was detected at both sites. At the northern site, the weight of the remaining LR, ground vegetation and all other material above the mor layer in the treatments with two and four times the estimated LR amount was roughly twice the corresponding weights at the southern site seven years after treatment. Although strong effects on the soil-solution chemistry were detected at one of the study sites, in the treatments corresponding to two and four times the estimated logging residue amount, the effect on the leaching from an entire regeneration area is likely to be relatively small given the percentage of the area hosting these logging residue amounts (ca. 20% after stem-only harvesting and 9% after fuel-adapted felling). 3--2+

© iForest -Biogeosciences and Forestry IntroductionCoarse woody debris (CWD) is one of the most important functional and structural components of forest ecosystems (Harmon et al. 1986, McComn & Lindenmayer 1999. CWD affects nutrient cycling, carbon storage and hydrological processes. It also serves as an essential substrate for a multitude of species, including numerous rare and endangered species (von Oheimb et al. 2007).Numerous studies have examined the role of CWD in maintaining biodiversity (Esseen et al. 1997, Angelstam 1998, estimating the decomposition rates of many important tree species (Yatskov et al. 2003), evaluating the effect of CWD in carbon and nutrient cycles (Krankina et al. 1999, Hyvonenn et al. 2000, Merganicôvá & Merganic 2010 and analyzing the quantity, structure and dynamics of CWD in managed and unmanaged forests (Green & Peterken 1997, Linder et al. 1997, Siitonen et al. 2000, Lombardi et al. 2008. In unmanaged forests, the amount of CWD is the result of tree mortality and dead wood decay rates, both of which are affected by climate, site productivity, tree species composition, disturbance regime, previous forest stand characteristics and the successional stage of the forest (Harmon et al. 1986, Spies et al. 1988. In managed forests, CWD quantities are typically kept very low, to avoid pest problems and fire hazards and to maximize the commercial value of the harvest. Where economics and accessibility allow, trees affected by insects, diseases, and fire are usually removed immediately, before they die or deteriorate (DeBell et al. 1997, Green & Peterken 1997. Plantation forests are typically managed on short rotations and are generally subject to intensive harvesting methods, resulting in structurally homogenous stands without significant amounts of CWD (Harmon et al. 1986, deMaynadier & Hunter 1995. However, silvicultural activities such as thinning, pruning and harvesting can create woody debris (Carlyle 1995). The increasing importance of biodiversity and carbon storage favors the maintenance and promotion of CWD in managed forests. Leaving some live and dead trees during logging operations, or even killing trees to create CWD, are some of the operational means for meeting biodiversity needs in managed forests (Esseen et al. 1997).The amount and distribution of CWD can be a criterion for assessing and determining baseline silvicultural practices. This type of data is available for different types of forests, but the geographic extent and focus of most studies is limited to one or a few specific stands. There is very little information on continental or global CWD quantities and distribution patterns or on how management affects these patterns. Comparison of different forest ecosystems makes it possible to examine the effects of site productivity and stand structure on CWD amounts and decomposition rates. It also improves understanding of how different management practices affect CWD as a resource, which is vital to formulating guidelines and strategies for increasing carbon storage ...

“…Litter resulting from typhoon is usually composed of lot of green leaves and twigs. Green leaves are rich in nutrients and soluble organic C fractions, and is, therefore, qualitatively very different from the normally fallen litter materials [11,16,37]. The addition of a high amount of green leaves may also affect the decomposition and nutrient dynamics on the forest floor.…”

-Decomposition of typhoon-generated and normally fallen needles and their dynamical patterns of nutrient release for ten elements (C, N, P, K, Ca, Mg, S, Fe, Al, and Mn) were investigated over 3 yr using the litterbag technique in a subtropical pine plantation (Pinus luchuensis Mayr.) in Okinawa, southwestern Japan. After 3 yr, decomposition rates (k values) were 0.361 and 0.323 yr −1 , respectively, for typhoon-generated and normally fallen needles. The typhoon-generated needles decomposed significantly more rapidly than the normally fallen needles did, which was due to the higher N and P concentrations. Nutrient transfer patterns for elements varied greatly. However, significant differences in mass dynamic patterns of elements between typhoon-generated and normally fallen needles were found only in N and P (P < 0.001). Nutrient mobilities during the decomposition processes were similar in both typhoon-generated and normally fallen needles and was ordered as follows:Rapid decomposition with rapid release of P and N in typhoon-generated needles indicates that typhoon disturbances can drive P and N cycling at a somewhat higher rates, which is more important from the standpoint of forest productivity since P and N are limiting nutrients in the subtropical forests in Okinawa.litter chemical quality / needle decomposition / nutrient release / pine plantation / Pinus luchuensis / typhoon impact Résumé -Dynamiques des nutriments dans les aiguilles en décomposition de Pinus luchensis après les perturbations liées à un typhon dans un environnement subtropical. La décomposition des chutes d'aiguilles normales et occasionnées par un typhon et leur modèle de libération des nutriments ont été étudiés pour 10 éléments (C, N, P, K, Ca, Mg, S, Fe, Al et Mn). L'étude a été faite dans une plantation de pin (Pinus luchensis Mayr.) à Okinawa (SO du Japon). Elle a duré 3 ans et a utilisé la technique des bacs à litière. Après 3 ans les taux de décomposition étaient de 0,361 et 0,323 an −1 respectivement pour les chutes d'aiguilles liées au typhon et les chutes normales d'aiguilles. Les chutes aiguilles liées au typhon se décomposent significativement plus rapidement que les chutes normales d'aiguilles, ce qui est du à une plus forte concentration en N et P. Les modèles de transfert des éléments varient fortement. Toutefois, des différences significatives dans les modèles de dynamique de masse des éléments entre les deux types de chute d'aiguille ont seulement été mises en évidence pour N et P (P < 0,001). La mobilité des éléments pendant les processus de décomposition étaient similaires dans les deux types de chute d'aiguilles et s'ordonnait de la façon suivante : K > Ca ≥ Mg ≥ C > S ≥ N ≥ Mn > P Fe ≥ Al. Une décomposition rapide avec une libération rapide de P et N pour les aiguilles dont la chute a été occasionnée par le typhon indique que la perturbation par le typhon peut conduire le cycle de P et N à un taux quelque peu plus rapide, ce qui est important du point de vue de la productivité de la forêt puisque P et N son...
