This project aimed to estimate organic litter loads at Mulcra and Lindsay floodplains, and to quantify potential concentrations of dissolved organic carbon (DOC) leached from litter on the floodplains during managed flooding. Litter was collected from 4 vegetation communities, Red gum (RG), Black box (BB), Lignum (LG) and Other (OT), from sites within and outside the influence of managed inundation referred to herein as ‘watered’ and ‘unwatered’ sites, within each floodplain. Litter was subsequently fractionated into leaves, bark, sticks, plants and ‘other’ (which included all material not assigned to any one of the other categories) and weighed to determine mass (and percentages) of each fraction and overall total litter loads. Dissolved organic carbon (DOC) leaching experiments were conducted to determine the potential amount of DOC produced from each material and to estimate potential total leachable DOC concentrations for each floodplain.
