Pigtoe excluded from endangered list

Based on genetic studies and reviews of the best available science, the U.S. Fish and Wildlife Service (FWS) reports, it has determined the triangle pigtoe does not warrant protection under the Endangered Species Act (ESA). The May 10 decision, also known as a 12-month finding, is the result of a taxonomic study indicating the East Texas mussel is not a distinct species.

In 2009, FWS determined that the triangle pigtoe may warrant listing under the ESA. However, genetic studies have determined that the triangle pigtoe is synonymous with a more widespread, common mussel called the Texas pigtoe. As such, the triangle pigtoe is not a listable entity under the ESA.

 The Texas pigtoe mussel is found in the Neches River basin and its tributaries in Angelina, Cherokee, Hardin, Jasper, Jefferson, Liberty, Nacogdoches, Orange, Polk, Rusk, Sabine, San Augustine, Shelby, Smith and Tyler counties in East Texas.
