Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.
Sinanodonta tumens is a freshwater bivalve endemic to Lake Biwa, Japan. This species has not been reported anywhere outside of its native range, resulting in a history of invasiveness of No Known Nonnative Population. The overall climate match with the contiguous United States was High, especially in the southern and eastern regions. The climate match was based on the written description of the species range as no georeferenced observations were available. The certainty of assessment is Low due to lack of information, particularly when excluding information attributed to S. ogurae which several recent sources consider to be synonym of S. tumens. The overall risk assessment category for S. tumens is Uncertain.
