Endangered and Threatened Wildlife and Plants; Reclassifying Tobusch Fishhook Cactus From Endangered to Threatened and Adopting a New Scientific Name

We, the U.S. Fish and Wildlife Service (Service), reclassify Tobusch fishhook cactus (Sclerocactus brevihamatus ssp. tobuschii; currently listed as Ancistrocactus tobuschii), from endangered to threatened on the Federal List of Endangered and Threatened Plants. This determination is based on a thorough review of the best available scientific and commercial information, which indicates that the threats to this plant have been reduced to the point that it is no longer in danger of extinction throughout all or a significant portion of its range, but it remains threatened with becoming endangered within the foreseeable future. In addition, we accept the new taxonomic classification for Tobusch fishhook cactus as the subspecies Sclerocactus brevihamatus ssp. tobuschii.
