Project summary:
The object of this study is to examine how volume, mass and C-content of CWD in tall wet Eucalyptus obliqua forests changes with increasing time since wildfire or harvesting disturbance. The plots that comprise the wildfire chronosequence project will be used for this study. CWD data from 5 south-facing plots have already been collected. To complete the dataset, the study will focus on the remaining seven plots and will make use of sampling efficiency improvements developed by this earlier study. These include excluding branches, measuring only logs above 50 cm in diameter, and assigning only a single decay-class to each log. To calculate carbon-content, mean wood density and carbon concentration of each decay-class needs to be obtained. This will be done by using samples of rotten wood types collected previously, for which C content will be determined. These rotten wood types will be linked to decay classes, to allow the calculation of an average C density for different decay classes.
