On August 11, 2023, the U.S. Fish and Wildlife Service (Service) published a proposed rule to delist the Apache trout (Oncorhynchus apache) under the Endangered Species Act (ESA) due to the species’ recovery.  The Apache trout, the state fish of Arizona, is a species of freshwater fish that is found primarily in the mountain region of southeast Arizona.  This species was initially listed as an endangered species under the ESA in 1967.  Then, in 1975, the Service downlisted the species to threatened status.  The ESA defines a threatened species as one that is “likely to become ...

On January 12, 2022, the General Land Office of Texas (GLO) filed a lawsuit in the U.S. District Court for the Western District of Texas, challenging the U.S. Fish and Wildlife Service’s (Service) July 27, 2021 negative 90-day finding on a petition to delist the endangered golden-cheeked warbler (Setophaga chrysoparia) (Negative 90-day Finding). The Negative 90-day Finding is the second 90-day finding issued by the Service on the same petition to delist the golden-cheeked warbler.

On November 3, 2020, the United States Fish & Wildlife Service (“Service”) published a final rule removing the gray wolf (canis lupus) from the federal list of Endangered and Threatened Species in the lower 48 United States and Mexico. The rule will take effect on January 4, 2021. At the same time, the Service denied a petition, filed by environmental groups, to maintain protections for the gray wolf in the lower 48 United States.

On December 15, 2016, the U.S. Fish and Wildlife Service (Service) published a proposed rule to remove the black-capped vireo (Vireo atricapilla) from the list of Endangered and Threatened Species. The Service has concluded that listing is no longer warranted due to the species’ recovery.

The vireo is a small migratory songbird that breeds and nests in south-central Oklahoma, Texas, and the northern states of Mexico, and winters in Mexico’s western coastal states. The species was initially listed as endangered in October 1987 due to various threats, including nest parasitism ...
