L. V. Mukhortova, E. F. Vedrova Contribution of Large Wood Remnants to Organic Matter Reserves in Forest Ecosystems of Secondary Successions after Cuttings // Forest Science (Lesovedenie). 2012. No 6. С.55-62. A stock of coarse woody debris (CWD) in forest ecosystems of secondary successions in pine and fir stands of eastern Lake Baikal basin was estimated. In the control variants of the pine and fir forests, a relative contribution of coarse woody debris to the total organic matter pool was found to amount to 10.3-12.5%. In the undamaged forests studied, the CWD contribution to the total phytodetritus reserves is 34--38%. On the fresh felled area in the fir forest, their contribution was greater (68.6-83.2%). A rate constant for CWD decomposition in pine and fir forests was determined. Forest ecosystems, coarse woody debris, stock, decomposition rate.. |
