Global Range: Pediocactus peeblesianus var. fickeiseniae is found only in Coconino and Mohave counties, Arizona. It grows along the northern and southern ledges of the Colorado and Little Colorado Rivers to the hills of lower House Rock Valley. Sites are isolated from one another by topography and unsuitable habitat (Falk 2007, USFWS 2012). Fickeisen Plains cactus was described from collections made, independently, by Miss M. Cowper on the Little Colorado River and Mrs. Florence Fickeisen, north west of the Grand Canyon in 1956 (Marshall 1956 from Benson 1969). In June 1957 and 1958, collections were made by Lyman Benson near Cameron, Arizona. Plants have continued to be found in these areas. On BLM land, the geographic range extends from Marble Canyon, on the east, westwards to Mainstreet Valley. The area where they are found on Bureau of Land Management and Navajo Nation lands is known as the Arizona Strip (Benson 1969, Hughes 1995a). Other scattered locations in the Arizona strip where this cactus is found include Hurricane Valley, Hurricane Cliff tops, Clayhole Ridge, Sunshine Ridge, and Houserock Valley. These localities are all on public lands managed by the BLM (Hughes 2000). Further, this species is known from the south and east of the Colorado River, on Navajo Nation lands, between Echo Cliffs, the Grand Canyon and the Little Colorado River gorge. One other location is known from Gray Mountain (Arizona State Trust and private lands) (Hughes 2000). A detailed description of populations is found in the proposed listing document (USFWS 2012).
