Seasonal Variability of Benthic Macroinvertebrate Communities and stream habitat characteristics in Two Ecozones in Northern Ontario, Canada

The Ring of Fire in the Far North of Ontario, Canada is considered be one of the most promising mineral development opportunities in Ontario in almost a century. Covering an area of about 5,000 km² in two ecozones, recent estimates suggest that the Ring of Fire holds significant potential production of nickel, copper and platinum as well as potential for world-class multi-generational production of chromite. Baseline environmental data has been collected in the region, including mid-summer stream data to be used in future Reference Condition Approach bioassessments. In this study, we examined seasonal variability in stream site characteristics and benthic invertebrate communities by sampling 43 stream sites, split between the Hudson Bay Lowland and Boreal ecozones, at spring post-breakup, mid-summer and the fall of 2015. Quantifying seasonal variation of habitat characteristics and biotic communities at these sites, and the influence of ecozone location on that variability, will be an important component for future bioassessments aimed at detecting and characterizing effects of mining development and associated activities in the region.
