5203 |a"A global, standardized approach for assessing threats, the IUCN-CMP Unified Classification of Direct Threats, was formally implemented in 2012 by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). After a decade of use, an inventory was created to describe threat scores across all 11 Level 1 and 44 Level 2 threats categories for aquatic species assessed by COSEWIC between 2012 and 2021, which included 73 freshwater fishes, 24 marine fishes, 18 marine mammals, and 12 freshwater molluscs. Among these taxa, freshwater species were more frequently threatened by Invasive Non-Native/Alien Species, while marine species were more frequently threatened by Fishing and Harvesting Aquatic Resources. Marine fishes had the lowest threats calculator completion rate, while freshwater molluscs had the highest. Freshwater fishes had the most diverse suite of assigned threats categories, while marine mammals had the least. The most common threat to marine fishes was Other Ecosystem Modifications, a catch-all category that captures a wide variety of direct threats. The most common threats to freshwater molluscs were Household Sewage and Urban Waste Water and Agricultural and Forestry Effluents. While Climate Change was indicated as a potential threat to the majority of aquatic species, the impact was often unknown. Overall, this inventory may be used to better understand the application of the threats calculator to aquatic species assessments in Canada"--Abstract, page vi.
