Design of ecological risk criteria for the integrated management of Canadian oceans / Jonathan A. Freedman and Derrick T. de Kerckhove. : Fs70-5/2015-015E-PDF

Ecological risk criteria (ERC) are used in Canada and around the world within risk assessment and management frameworks. The purpose of this Research Document is to evaluate and compare ERC risk categories and thresholds for use within the context of DFO’s ecosystem-based integrated oceans management (IOM) plan. In particular, we investigated how DFO’s 2006 ERC were aligned with existing categories and thresholds used within other existing frameworks, and the biological significance of each criterion. Within that context, we asked: how realistic is it to compartmentalize spectrums of risk into separate categories and thresholds; and, for nationally applicable ERC, how do we assign risk categories and thresholds that are general enough to be applied across a wide range of situations, geographic locations and scales, timings and human activities, yet specific enough to address complex ecological responses to environmental pressures?
