Its two subspecies differ in range. subsp. ferreirianus is located in the eastern region of central Baja California and adjacent islands of Baja California while subsp. lindsayi is restricted to a region south of Cataviña in central Baja
Habitat and Ecology: Echinocereus ferreirianus grows on rocky mountains, low hills, slopes, and cliffs. It has been reported from shrub desert in pumice slopes, lava fields and in stony-loamy granite. The only threat is illegal collecting, in specific of the subspecies subsp. lindsayi.
