• Abstract:

  Leaf litter was collected at the time of soil respiration measurements and its moisture content was measured in order to determine the contribution of leaf litter decomposition to measurements of total soil respiration including the litter layer. Leaf litter moisture has been shown to strongly affect CO2 release from organic soil layers (Borken et al. 2003).

• Methods:

  Ten leaves from the uppermost layer of leaf litter were collected at each location where soil respiration was measured. The leaves were immediately placed into a tightly closed plastic bag, and at the end of the day they were weighed. They were then dried at 70 degrees C for two days and reweighed. Leaf moisture content was then calculated as a percentage of the dry weight for each sample.
