Cibola National Wildlife Refuge Cibola National Wildlife Refuge straddles the Colorado
River, with about two-thirds of the Refuge in Arizona.
The California section includes river-bottom lands and the lowest slopes
of the Palos Verdes Mountains. In
the washes of the latter, ironwood, Olneya tesota, palo verde, Cercidium
floridum, and mesquite, Prosopis glandulosa var. torreyana, are found; however, most of the
desert vegetation is creosote bush scrub, with Larrea tridentata predominant. Much of the bottom land has been or is in agricultural
production, but there are isolated stands of willows, Salix sp., and
cottonwoods, Populus fremontii. Tamarisk, Tamarix sp., has replaced much of the
native vegetation. Along the old
river channel there are some freshwater marshes with Typha sp. and Scirpus sp. Animal life is quite abundant.
Some 202 species of birds have been observed on the Refuge.
Wood ibis, Mycteria americana, white-faced ibis, Plegadis
chihi, and
Harris's hawk, Parabuteo unicinctus, are seen here.
The endangered Yuma clapper rail, Rallus longirostris yumanensis, breeds
here. Varieties of geese and duck
use the area during the migratory and winter seasons.
Twenty-seven reptile species have been recorded on the Refuge. Integrity: The
area has been heavily impacted by agriculture and river diversion.
Established in 1964, the Refuge is managed for waterfowl. Use: Present January 1980
