“…Comparing CWD estimates from different studies requires caution due to variations in field measurement methods, plot selection, the area of the region studied and calculation procedures among studies (Fridman & Walheim 2000, Grove 2001. One limitation of this study is that the sampling methods, designs and minimum piece sizes in the three regions were not exactly the same, though they all are standard procedures for sampling CWD in different parts of the world.…”

© 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 ...

Meriem S., Tjitrosoedirjo S., Kotowska M.M., Hertel D., Triadiati T., 2016. Carbon and nitrogen stocks in dead wood of tropical lowland forests as dependent on wood decay stages and land-use intensity. Ann. For. Res. 59(2): 299-310.Abstract. Rapid transformation of natural forests into other land-use systems in the lowlands of Sumatra, Indonesia, strongly reduces total aboveground biomass and affects nutrient cycling. However, the consequences of this conversion for C and N stocks of dead wood remains poorly understood particularly in natural forests and jungle rubber. This study examined the differences in dead wood abundance, mass, and C, N and lignin concentrations of three decay stages of dead wood as well as the stocks of these chemical components stored in dead wood. Standing and fallen dead wood was determined as coarse woody debris with diameter ≥ 10 cm and classified into three decay stages of wood. Mass of dead wood was estimated using allometric equation. Total C and N stocks in dead wood in the natural forests (4.5 t C ha -1 , 0.05 t N ha -1 , respectively) were three times higher than those in the jungle rubber (1.5 t C ha -1 , 0.02 t N ha -1 , respectively). The stocks of C and N at early and advanced wood decay stages in the natural forests were also higher than those in the jungle rubber. The decay stages showed pronounced differences in concentrations of chemical components. With advancing stage of wood decay, N concentration increased and C/N ratio decreased, while concentrations of C and lignin were variable. The distribution of dead wood mass and stocks of C, and lignin were found to be higher in the early decay than those in the advanced decay stage. Higher input of dead wood in natural forests indicated a higher importance of dead wood decay in natural forests than in jungle rubber systems. Thus, replacing natural forests with jungle rubber strongly reduces total C and N stocks which might have a marked negative effect on the ecosystems' nutrient turnover and cycle.

“…Fallen necromass was measured using line intercept sampling and standing dead was measured using plots in a few studies (Nascimento andLaurence 2002, Palace et al 2007). One study used plots except for one area in which dense understory prohibited movement and line intercept sampling was used (Grove 2001). Baker et al (2007) compared line intercept with plot sampling and found similar values for necromass volume and estimated the fallen mass.…”
