A small mammal survey was conducted in August 2014 at the northern tip of the Ungava Peninsula (Nunavik, Québec), as part of an environmental and social impact assessment. Three species of rodents were captured using snap traps: the Ungava collared lemming (Discrostonyx hudsonius), the meadow vole (Microtus pennsylvanicus), and the northern bog lemming (Synaptomys borealis). The northern bog lemming specimens represent the northernmost records for this species in Québec. The farthest north in the province that this species had previous been found was 311 km south of the most northerly occurrence reported in this study.
