Endangered Species Status With Critical Habitat for Guadalupe Fatmucket, Texas Fatmucket, Guadalupe Orb, Texas Pimpleback, and False Spike, and Threatened Species Status With Section 4(d) Rule and Cri
Aug. 26, 2021
USFWS proposes to list six Central Texas mussel species: The Guadalupe fatmucket (Lampsilis bergmanni), Texas fatmucket (Lampsilis bracteata), Texas fawnsfoot (Truncilla macrodon), Guadalupe orb (Cyclonaias necki), Texas pimpleback (Cyclonaias petrina), and false spike (Fusconaia mitchelli) as endangered or threatened under ESA. After review they find that listing Guadalupe fatmucket, Texas fatmucket, Guadalupe orb, Texas pimpleback, and false spike as endangered species is warranted, and listing Texas fawnsfoot as a threatened species is warranted. Proposed arule issued under section 4(d) of the Act (``4(d) rule') for Texas fawnsfoot. If finalized this rule would add these species to the List of Endangered and Threatened Wildlife and extend the Act's protections to the species. They also propose to designate critical habitat for six species under the Act. Approximately 1,944 river miles (3,129 river kilometers) in Texas fall within the boundaries of the proposed critical habitat designations, and the availability of a draft economic analysis (DEA) of the proposed designation of critical habitat. They will accept comments received or postmarked on or before 25 October 2021.
