This document discusses monitoring and management of aquatic macrophytes in tropical Brazilian reservoirs. It introduces aquatic macrophytes and their importance in ecosystems. It emphasizes the need for continuous monitoring to properly manage macrophyte growth, which can impact water quality and uses of reservoirs. The document then analyzes causes of excessive macrophyte proliferation in Brazilian reservoirs and measures taken to mitigate impacts. It also addresses disposal and potential uses of removed macrophyte biomass, eutrophication issues, and a proposal to establish monitoring and management centers.
