The effects of harvesting wetlands vegetation on nutrient contents entering Layang reservoir, in Masai Johor were investigated. Total Phosphorus (TP), Total Dissolved Phosphorus (TDP) and Nitrate-N levels at the harvesting site, both upper and bottom layers were lower compared to the control site and the inflowing river. The monthly percentage removals of TP, TDP and Nitrate-N fluctuated noticeably, ranging from 20% to 89%. Percentage removals were also higher after harvesting operation compared to before harvest. The percentage removal is highest when the shoots are young.
