“…Thinning can alter mineral soil C storage by increasing root mortality, incorporating thinning residues, and changing litter production and heterotrophic soil respiration (Hwang & Son 2006, Ko et al 2014, Schilling et al 1999. Even though two larch stands exhibited significant increases in mineral soil C storage three years after thinning, it was found that these significant increases were not common in the present study as the impact of thinning on mineral soil C storage was minimal in other study stands.…”

“…As thinning with the stem-only harvesting can promote the incorporation of thinning residues into dead organic matter C pools (Hytönen & Moilanen 2014, Ko et al 2014, we expected increases in the C storage of dead organic matter following thinning. Nevertheless, the obtained results imply that the applied thinning treatments did not consistently increase the C storage of dead organic matter within the study stands at least after three years.…”

“…The mechanisms behind these differences in the effects of thinning between needle-leaved and broad-leaved forests remain unclear. However, initial shifts of mineral soil C in thinned needle-leaved forests are often attributed to the significant input of organic matter from dead roots, leaves, and slashes of thinned trees (Hwang & Son 2006, Mu et al 2013, Ko et al 2014). Thus, differences in mineral soil C patterns due to thinning might result from differences in the decomposition rate of incorporated organic matters, because quality and recalcitrant constituents of organic matter vary between species (Silver & Miya 2001).…”

“…Fallen leaves, branches, and coarse woody debris (CWD) are the primary forms of dead organic matter, whose quantity and quality are related to the succession stage and forest management (Powers et al 2012, Ko et al 2014. Mineral soil stores a large volume of organic C derived from the primary forms of dead organic matters.…”

(1-4) Dead organic matter is important in carbon (C) sequestration because it accounts for a significant proportion of forest C storage. As thinning could alter the C storage of dead organic matter, this study aimed to assess the effect of thinning on the C storage of dead organic matter including the forest floor, mineral soil at a depth of 0-30 cm, and coarse woody debris in larch and oak forests in South Korea. Differing intensities of thinning were applied to four larch and four oak stands, and the C storage of dead organic matter in thinned and control plots was compared three years after thinning. The effect sizes were estimated based on Hedges' d to measure the influence of thinning. Total C storage of dead organic matter tended to be higher in the thinned plots (larch: 82. ). However, estimation of effect size found that the cumulative effect size was not significant for the C storage of the forest floor, mineral soil, coarse woody debris, and dead organic matter. Only a few of the individual treatments exhibited significant effect sizes for mineral soil C storage in two larch stands and coarse woody debris C storage in two oak stands. The results indicated that the applied thinning treatments might have no consistently significant impact on the C storage of dead organic matter in the larch and oak stands after three years, though thinning may have had an idiosyncratic influence on the C storage of dead organic matter in a few of the study stands.

“…This species accounts for approximately half of the coniferous forest cover in South Korea and is used for various purposes [14,15]. Studying the roles of pine CWD is important, given that forest management activities and outbreak of pine wilt disease in South Korea can generate large volumes of pine CWD [16,17]. Nevertheless, not many studies have focused on the interactions between pine CWD and soils of South Korea.…”

Abstract:Although coarse woody debris (CWD) is important for soil functioning, the mechanism which affects soil properties beneath CWD are unclear. Here, initial changes in microbial and soil properties were studied using homogenous CWD samples in eight Korean red pine (Pinus densiflora Sieb. et Zucc.) forests. For each forest, CWD samples (diameter: 11.1 ± 0.1 cm; length: 10.2 ± 0.0 cm) from similarly aged Korean red pine trees were laid on the mineral soil surface from May to June, 2016, and soils were sampled at points beneath CWD and at a distance of 1 m from the CWD after 1 year. Soils beneath the CWD had higher moisture but lower inorganic nitrogen (N) and a higher microbial biomass C (carbon)/N ratio than those sampled 1 m from the CWD. No differences in total C and N, labile C, pH, and C substrate utilization between the soils were significant. The difference in inorganic N between the soils decreased with increasing CWD decomposition, whereas that for microbial biomass fraction in total C and N increased correspondingly. Our results showed that soil microbial affinity for retaining N might become higher than that for retaining C under the presence of CWD, which possibly alters N availability and generates a spatial heterogeneity in forest soils.

Coarse woody debris (CWD) respiration (RCWD) has strengths in efficient investigation of CWD decomposition rate and application into studies on ecosystem carbon (C) processes. Here, RCWD was investigated in two Japanese red pine forests to determine its response to environmental factors and CWD properties, and its contribution to the ecosystem C budget. Samples were collected based on CWD position (log or snag), species (pine or deciduous), and decay class in the Gwangneung pine forest (GPF) and the Mt. Jumbong pine forest (JPF), Korea. RCWD was measured at different incubation temperatures using a closed chamber system. Annual RCWD was estimated by developing and applying air temperature–RCWD regressions to air temperature data. In the GPF, annual estimated RCWD (g C kg−1 year−1) was 29.54, 3.90, and 158.95 for pine logs, pine snags, and deciduous logs, respectively. In the JPF, RCWD was 49.09 for pine logs and 14.55 for pine snags. Temperature and CWD moisture were the main drivers of RCWD. CWD species also influenced RCWD, possibly by supporting different habitats for microbes and invertebrates. RCWD in the GPF accounted for approximately 4 % of heterotrophic respiration and 54 % of the CWD decomposition rate. In the JPF, RCWD was approximately equal to the CWD decomposition rate. RCWD might constitute a minor portion of the net ecosystem production (4 % in the GPF), because of the relatively high stand productivities and small CWD masses. In the GPF, the major factor influencing RCWD was mortality, whereas moisture had the greatest influence on RCWD in the JPF.
