| In summary, there were five key learnings within this project. First, the net primary production of the sedge species, excluding C. canescens, was similar to values reported from natural peatland sites. Second, belowground net primary production of the four sedge species ranges from 54% -- 67.5% of total net primary production. Third, organic matter accretion may indicate significant inputs of organic matter from non-vascular plant species. Fourth, net primary production results of the four sedge species is quite similar to net ecosystem exchange results, indicating that these different measurements may be closely related. Finally, the monoculture planting areas of all four species are acting as an annual source of carbon; however, C. aquatilis plantings have the greatest potential potential to provide a source of organic matter to the upper peat column in the coming years.
