Title: A conceptual approach for the application of biological indicators of ecosystem quality in the Great Lakes Basin, a joint effort of the International Joint Commission and the Great Lakes Fishery Commission
Author: Ryder, R. A.; Edwards, C. J.; Ontario Ministry of Natural Resources, Fisheries Branch; Great Lakes Regional Office, International Joint Commission
Abstract: The International Joint Commission (IJC) and the Great Lakes Fishery Commission (GLFC) according to their respective mandates, have collaborated in a new initiative under the general purview of an ecosystem approach directed towards the management of the environment and resources of the Great Lakes Basin. This initiative logically followed upon the 1955 Great Lakes Fisheries Convention and the 1978 Great Lakes Water Quality Agreement between Canada and the United States, both of which were intended to provide continuing protection under rational use for fishery resources and the environment within the Great Lakes Basin ecosystem. A prerequisite for appropriate application of an ecosystem approach is the need to determine the current state of health of the environment and its contained resources and to identify the areas where the system may be unduly stressed by cultural interventions. The task of advancing the ecosystem approach concept and subsequent application in management was assigned to a Work Group of the Aquatic Ecosystem Objectives Committee (AEOC) (Work Group on Indicators of Ecosystem Quality (WGIEQ)) which, in turn, reports to the Great Lakes Scientific Advisory Board of the International Joint Commission. The WGIEQ used as its general terms of reference the First Recommendation of the First Biennial Report (IJC 1982) under the Water Quality Agreement of 1978. The WGIEQ's more specific terms of reference were to: appraise, evaluate and critique the feasibility of using an indicator/integrator organism as a surrogate of the state-of-health of the Great Lakes, to produce an ecosystem objective and supporting rationale for inclusion into any future revisions of the 1978 Water Quality Agreement, to identify appropriate ecosystem variables for future monitoring, and to explore and develop, where appropriate, other ecosystem approaches applicable to the Great Lakes Basin. This assignment was completed and is outlined in this document.
