Existing Protection or Other Status

Lampsilis cariosa is listed as threatened throughout its range in the United States (Williams et al. 1993) and is protected in some states such as Massachusetts and Maine (D. Smith 1999; Nedeau et al. 2000).  It may be extirpated in some watersheds (Counts et al. 1991; Strayer and Jirka 1997). The species is being considered for listing under the US federal Endangered Species with current evidence of vulnerability but more research needs to be done before species can be listed (U.S. Fish and Wildlife Service 2004).
