Endangered Species Status for Echinomastus erectocentrus var. acunensis (Acu[ntilde]a Cactus) and Pediocactus peeblesianus var. fickeiseniae (Fickeisen Plains Cactus) Throughout Their Ranges; Final Rule

We, the U.S. Fish and Wildlife Service (Service), determine that Echinomastus erectocentrus var. acunensis (acu[ntilde]a cactus) and Pediocactus peeblesianus var. fickeiseniae (Fickeisen plains cactus) meet the definition of endangered species under the Endangered Species Act of 1973, as amended. This final rule implements the Federal protections provided by the Act for these species. The effect of this regulation will be to add these species to the List of Endangered and Threatened Wildlife and Plants under the Endangered Species Act.
