Response Statement - Shortface Lanx

This limpet-like freshwater snail is globally confined to the Columbia River basin. Historically known from the 1800s, the first recent evidence of the species in Canada was the discovery of a broken shell in the Columbia River near Trail, British Columbia, followed by live individuals being found in the same area in 2009 and 2010. Searches in 2014 confirm the species still exists in this short, free flowing section of the Columbia River. It requires flowing, clean, well-oxygenated, cold water, but the numerous dams on the Columbia River and its major tributaries have converted much of this habitat into reservoirs. The species is exposed to a variety of threats from natural system modifications caused by the dams, pollution from urban and industrial sources, invasive and problematic native species, and climate change.
