Woody debris production and respiration in FASET plots


Coarse woody debris (CWD) is a significant and growing component in forest ecosystems, especially those undergoing succession or withstanding disturbances. We combined CWD census data and in situ chamber respiration measurement to quantify the amount and carbon stored by CWD in an experimentally disturbed early successional aspen and birch forest. CWD was found to be 35.2 Mg C ha-1 of which was 29.3 Mg C ha-1 standing and 5.9 Mg C ha-1 was downed. Downed CWD respiration averaged 1.1 ┬Ám CO2 kg-1s -1, but significant differences were found based on orientation, side or end.
