The purpose of the Sustainable Ecosystems Working Group (SEWG) is to develop and recommend a management framework to the Cumulative Environmental Management Association (CEMA) and ultimately to the Government of Alberta to address cumulative effects on ecosystems and landscapes in the Regional Municipality of Wood Buffalo (RMWB) using sustainable development principles. The SEWG completed work on their Terrestrial Ecosystem Management Framework (TEMF) which was approved by the CEMA Board and forwarded to government in June of 2008. Further work to refine recommendations and outcomes of the TEMF were identified by CEMA and the Government of Alberta (GoA).
