The decomposition rate of CWD is a key missing link for a quantitative understanding of forest ecosystem functioning. We examined factors influencing decomposition rates of bark, roots and branches from aspen ( Populus tremula), birch ( Betula pendula, B. pubescens), fir ( Abies sibirica), spruce ( Picea abies, P. obovata), Scots pine ( Pinus sylvestris) and Siberian pine ( Pinus sibirica) CWD in three primeval European boreal forests. The chronosequence approach with estimates of single exponential decomposition rate ( k) based on calculation of mass loss was used. The k of non-stem parts increased in the order: branches (0.006 year for P. sibirica and 0.020 year for other species), roots in poorly drained sites (0.025 year), roots in well-drained sites (0.034 year) and bark (0.110 and 0.138 year and 0.147 and 0.255 year under poorly and well-drained conditions and from 1 to 3 m and >3 m above the root collar, respectively). Our results predict that the rate of decomposition of whole CWD pieces in European boreal forests is a function of vegetation zone, site conditions, tree species and size. [ABSTRACT FROM AUTHOR]
