• W2211070221 abstract "With respect to climate warming, carbon (C) sequestration is of important public and political interest. Forests represent important terrestrial C sinks. Their management can have direct and indirect influence on forest characteristics, including to some extent C sequestration. One direct effect of forest management is an increase in the stock of coarse woody debris (CWD). CWD represents a short- to middle term C sink that is of particular importance in natural and old-growth forests. Its impact on the soil organic carbon (SOC) stock is largely unknown.To investigate the impact of management, a case study was conducted in three adjacent managed and unmanaged forests with similar geological and micrometeorological conditions as well as similar tree species composition. In each forest, the C pools of the forest floor, the mineral soil and the CWD as well as their turnover times (TTs) or disappearance times (in case of CWD) were investigated. The unmanaged forests were withdrawn from management 40-100 years ago. The dominant tree species of temperate forests, European beech, Sessile oak and Norway spruce were considered. The experimental set-up permits to estimate how the C pools of a forest evolve within decades following its withdrawal from forest management.In each forest, the above-ground CWD stocks were inventoried. The volume and the decay class of each CWD piece was determined on an area of 1 ha. For each decay class, a representative number of samples of logs was sampled to measure wood density and C concentration. In addition, radiocarbon analysis and dendrochronological cross-dating were used to determine the time of tree death for CWD logs. From these data, disappearance times were calculated for the three tree species.In the unmanaged forests, the C stocks in the CWD accumulated to 10 Mg ha-1 in the spruce forest and to 24 – 30 Mg C ha-1 in the beech-oak forests. As such, the C stock in the CWD was 2 to 6 times greater in the unmanaged forests than in the managed forests where the C stocks in the CWD were around 5 Mg C ha-1 at all study sites. Average disappearance times of 30 and 70 years were calculated for beech and spruce CWD respectively. Oak CWD yielded a great variability of time since tree death at similar C densities of individual CWD pieces. The calculation of a decay function was thus not possible. However, the time since tree death of the dated oak CWD pieces indicated that oak CWD has the potential to remain in forests for more than 70 years. In addition to the field study, CWD samples of the three tree species and of three decay classes were incubated in a laboratory experiment under controlled conditions for a period of 380 days. In regular intervals, the CO2 production was measured and a leachate was produced to estimate the C fluxes from CWD in the gaseous and in the liquid phase. The yearly C loss was specific to the tree species and decay class. Beech CWD had the greatest C loss followed by oak and by spruce CWD. C loss generally increased with decay class for all tree species.…" @default.
