“…Globally, coarse woody debris (CWD) contains about 36-72 Pg of C (but see Russell et al, 2015 for factors that greatly affect such estimates), and the fate of this C will affect forest C dynamics ) as well as global surface C stocks with feedback to climate (Brovkin et al, 2012). In recent literature it has been proposed that leaving dead wood in the form of CWD in forests rather than clearing it, contributes to the system's C sequestration (Luyssaert et al, 2007;Gough et al, 2007;Nave et al, 2010;Cornelissen et al, 2012;Wiebe et al, 2014). Apart from C sequestration, CWD may also provide other ecosystem services such as a habitat, food and nutrients for numerous organisms.…”

“…Coarse woody debris also plays a crucial role in nutrient cycles (Wiebe et al 2014), and acts as a nutrient buffer maintaining long-term soil fertility (Herrmann and Bauhus 2018). In particular, CWD can act as a nitrogen (N) sink during the decomposition process (Palviainen et al 2010), promoting initial N immobilization followed by a slow-release increasing the N efficiency of the stand (Wiebe et al 2012), and increasing total N stocks (Wiebe et al 2014). Additionally, CWD improves soil characteristics such as pH and physical properties (Moghimian et al 2020).…”

There is a trade-off between leaving coarse woody debris (CWD) in the stand, providing desirable ecosystem services, and harvesting it. To consider this trade-off, forest management needs to model describing the decomposition of CWD. When a trunk is lying on the ground, it can be attacked by microorganisms faster than when it is still standing. Current decomposition models fail to account for these local differences in processes, which may give rise to errors in the estimation of stand C balance. We extended the Q decomposition model to represent the influences of tree species and the local position of the wood. We utilized data from two studies on long-term deadwood decomposition in forests. We first calibrated the model on the whole dataset, and then divided the data into different CWD decomposition classes, and then allowed some of the parameters to vary between different CWD decomposition classes. The calibrations were performed within a Bayesian framework, which allowed for a statistically sound comparison of the calibration results. The difference between the remaining C mass predicted by the two versions of the model, one considering one single calibration for all decomposition classes and one specific to decomposition classes, depended on the CWD class but was in general substantial. Some classes, when modeled with a specific parameterization, resulted in C stocks after 50 yr 1-5 times less than that predicted by the single parameterization model. Logs decayed faster than snags, and birch wood much faster than pine and spruce wood, with little difference between the two conifers. Russian spruce wood decomposed somewhat faster than Finnish spruce wood. Incorporating our calibration, describing specifically the processes driving the wood decay locally, into a C balance model of forests may change model estimates substantially.

“…Decaying logs and their concomitant gaps are widely distributed in forest ecosystems (Harmon et al 1986), and both play vital roles in conserving biodiversity (Tinker and Knight 2000), maintaining site fertility (Wiebe et al 2014), promoting soil development and forest regeneration (Forrester et al 2012) and the cycles of carbon (C) and nutrients (Laiho and Prescott 2004). Interestingly, fallen logs are exposed in different microenvironments due to the formation of forest gaps, and as a consequence, an inevitable and close linkage between the position of canopy gap and the dynamics of C and nutrients in decaying logs can be observed.…”

Aims The redistribution of forest gaps based on solar radiation and precipitation (mainly rainfall and snowfall) can create heterogenous microenvironments inside and outside the gaps. Here, we investigated the effects of forest gaps on carbon (C), nitrogen (N) and phosphorus (P) stoichiometry in decaying logs by altering the microenvironments. Methods Minjiang fir (Abies faxoniana) logs of decay classes I-V were incubated in situ on the floor under the gap center (GC), gap edge (GE) and closed canopy (CC) in a subalpine forest in the eastern Qinghai-Tibet Plateau. The C, N and P concentrations in decaying bark, sapwood and heart-wood were measured in August from 2013 to 2016. Important findings Our results showed that the N concentration in bark decreased from the CC to the GC, while the opposite trend was found in sapwood and heartwood. Additionally, the C/N ratio in sapwood and heartwood of decay classes IV and V decreased from the CC to the GC, and the N/P ratio in heartwood of decay class V increased from the CC to the GC, implying that forest gaps have strong effects on C/N/P stoichiometry in highly decayed logs. Briefly, highly decayed logs are more susceptible to the microenvironment, and the proportion of highly decayed logs under the closed canopy or the canopy center should be appropriately adjusted if necessary.
