Assessing and monitoring aquatic ecosystem health : approaches using individual, population and community/ecosystem measurements / by Kevin Cash, National Hydrology Research Institute. Edmonton - Alberta : Northern River Basins Study 1995. ii, 70p. : references ; 28 cm. Northern River Basins Study project report 1192-3571 No. 45 "The specific objectives of this report are to: (1) Review the concepts of ecosystem health/integrity and cumulative effects assessment as well as the underlying framework and practical objectives of these approaches. (2) Critically review available literature on existing population, community and ecosystem-level approaches and associated metrics (measures) being used for assessment of aquatic ecosystem health/integrity and cumulative effects and briefly outline advantages and disadvantages of each technique. (3) Identify the types of data and information required to adequately assess and monitor aquatic ecosystem health/integrity and cumulative effects in large northern rivers. (4) Assess the applicability of these approaches and metrics to the Northern River Basins Study and, where possible, recommend approaches that could potentially be employed in the assessment and long-term monitoring of aquatic ecosystem health/integrity and cumulative effects within the Northern River Basins."--Introduction.
