This June 1, 2019 photo shows the rare desert wildflower Tiehm's buckwheat in the Silver Peak Range about 120 miles southeast of Reno, Nev., the only place it is known to exist in the world. The center has filed a petition to list it as an endangered species and is suing to U.S. Bureau of Land Management to try to protect it against mining operations in Nevada that the center says could lead to the flower's extinction.
