Adding value to water resource management through biological assessment of rivers

Water resource management encompasses a variety of regulations and mandates relevant to water protection and restoration. Awareness of the value-added biological monitoring and assessment to water resource management is increasing worldwide, but especially in countries that have implemented proactive water law and regulatory frameworks for protection of surface waters. Biological communities provide an integrated response to pollutants and human disturbance within watersheds through their continuous exposure to the magnitude, duration, and frequency of stressors, and, thus, are important for assessing ecosystem health. The selection of proper bioindicators can provide additional benefits through their use in causal analysis of impaired waters and measurement of ecosystem recovery after restoration. A process for implementing biological indicators in a monitoring and assessment framework is outlined for managers and practitioners of water resource protection and restoration.
