USFWS are reclassifying Fender's blue butterfly (Icaricia icarioides fenderi) from endangered to threatened under the ESA. Fender's blue butterfly is endemic to the Willamette Valley of Oregon. This action is based on our evaluation of the best available scientific and commercial information, which indicates that the species' status has improved such that it is not currently in danger of extinction throughout all or a significant portion of its range, but that it is still likely to become so in the foreseeable future. They are also finalizing a rule issued under section 4(d) of the Act that provides for the conservation of the species. This rule is effective 13 February 2023. POC is Craig Rowland, Acting State Supervisor, U.S. Fish and Wildlife Service, Oregon Fish and Wildlife Office, telephone 503-319-9488. (Federal Register 12 January 2023 [Rule] Pages 2006-2028)
