COSEWIC status appraisal summary on the Atlantic Mud-piddock Barnea truncata in Canada.: CW69-14/2-68-2021E-PDF

"In Canada, this intertidal marine bivalve species is restricted to small sections of Minas Basin in Nova Scotia. Here, the species is entirely dependent on the red-mudstone facies geological formation where it bores into the mudstone and remains as an immobile adult. Changes in sediment deposition can bury habitat, and smother and kill individuals. The main threat to the species is increased frequency and intensity of severe storms due to climate change, which can abruptly shift and redeposit sediments. Additional threats include human activities that change water current, erosion and sediment deposition patterns, pollution run-off from agricultural or urban sources, and climate-change induced sea-level rise"--Reason for designation, page iii.
