Federal officials are giving the public more time to comment on a proposal to protect two rare Arizona cactuses.
The U.S. Fish and Wildlife Service announced its intention last year to list the Acuna cactus and Fickeisen plains cactus under the Endangered Species Act.
The agency is proposing 54,000 acres of critical habitat for Acuna cactuses in Maricopa, Pima and Pinal counties, and 49,000 acres for Fickeisen plains cactuses in Coconino and Mohave counties.
Areas under the jurisdiction of the U.S. Department of Defense or American Indian tribes could be exempt if the agency determines that won't lead to the extinction of the species.
Additional comments on the proposal are being accepted through April 29.
