Background information and definitions
Agricultural and forestry effluents, which may contain chemicals, bacteria, excess nutrients, solid particles, and sediment, can enter rivers and other watercourses, and be discharged into the sea. Artificial wetlands may be created with the aim of retaining such pollution. For example, solid particles and sediment may sink in areas of slow water flow and plants growing on wetlands may remove excess nutrients (Brix 1994). Creating artificial wetlands near agricultural lands or forestry plantations may reduce the amount of pollutants reaching rivers and the sea, and therefore reduce the associated impacts on marine and freshwater mammals.
