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. Riparian buffers (uncultivated strips of vegetation along waterways) may be created to help reduce diffuse pollution from agriculture and forestry. For example, trees and plants within riparian buffers may trap sediments and solid particles and uptake excess nutrients (Collins et al. 2009). Establishing riparian buffers in agricultural and forestry areas may reduce the amount of pollutants reaching rivers and the sea, and therefore reduce the associated impacts on marine and freshwater mammals.
