Results from the Joint Oil Sands Monitoring plan (JOSM) presented here address the need to develop a comprehensive and robust invertebrate biomonitoring program for oil sands development in the lower Athabasca River and area. Benthic macroinvertebrate biomonitoring was conducted along the main stem of the lower Athabasca River, its primary tributaries and in the Peace-Athabasca delta to assess spatial and temporal change in ecological condition within these aquatic habitats. The study focused on macroinvertebrates because they are relatively sedentary, can be sensitive to multiple stressors, are critical components of fish habitat, and are the most common group used for aquatic bioassessments globally.
