This joint resolution would reject a Fish and Wildlife Service rule that designated six freshwater mussel and snail species found in Texas as endangered or threatened under the Endangered Species Act. The rule, published in June 2024, would have protected these species by establishing critical habitats where development and other activities would be restricted. The resolution was introduced by three Texas House Republicans and would nullify the rule entirely if passed, eliminating the federal protections for the Guadalupe Fatmucket, Texas Fatmucket, Guadalupe Orb, Texas Pimpleback, Balcones Spike, False Spike, and Texas Fawnsfoot. The legislation uses Congress's authority under the Congressional Review Act to disapprove federal regulations after they have been issued by executive agencies. If enacted, the rule would have no legal force and these species would lose their designated endangered or threatened status and associated habitat protections.
