E. crassipes is a free-floating aquatic macrophyte from tropical and sub-tropical freshwater environments. The excessive growth of this species is associated with nutrient enriched sites and causes detrimental impacts on water uses. In the central-southern part of the State of Bahia, Brazil, in addition to the adverse impacts on water resources, freshwater macrophytes have considerably affected the coastal zone. During periods of increased river flows, a large amount of macrophyte biomass is brought to the coast. This biomass covers extensive stretches of sand beaches,affecting tourism and recreation activities. The present paper analyzes the effects of E. crassipes infestation in the Cachoeira river watershed on the coastal zone of the municipality of Ilhéus. Management and control measures are discussed, considering the watershed as the unit of analysis.
