This species has experienced a decline due to pollution and habitat loss. In 2011 the United States Fish and Wildlife Service determined that although this species met the criteria for listing under the Endangered Species Act, its listing should be precluded for higher-priority species. Its current legal status is "Candidate".[1]
It was formerly classified under Quadrula, but in 2012 it was moved to Rotundaria based on genetic evidence.[2]
