A concept of aquatic macrophyte management that integrates the positive and negative aspects of vegetation in lakes and rivers is discussed. This integrated approach involves three factors: macrophyte control, macrophyte enhancement, and identification and resolution of the conflicts created by multiple use of a waterbody. The primary decision in macrophyte management programmes must be whether to optimise for singlepurpose or for multipurpose use of the waterbody. Both technical (macrophyte control and enhancement) and social (conflict resolution) procedures are required to solve problems associated with the macrophyte status of multipurpose waterbodies.
