Natural historyEdit
The habitats of the refuge are a unique blend of Mojave Desert and Sonoran Desert uplands, desert riparian zones, and marsh wetlands habitats, provides for a diverse array of flora and fauna.
FloraEdit
The ecosystem within the Bill Williams River National Wildlife Refuge is situated in an ecotone (transition zone) between Mojave Desert and Sonoran Desert ecoregions, increasing diversity of plant species present within it, There are few places in the Arizona deserts where one can view saguaro cacti forests, wetland broadleaf cattail (Typha latifolia) stands, and cottonwood woodlands in a single viewshed.
The refuge protects the largest remaining stand of the cottonwood-willow forests plant community along the lower Colorado River, with Fremont's cottonwood (Populus fremontii) and Goodding's willow (Salix gooddingii) the primary tree species.
FaunaEdit
The rare desert context riparian habitat of Bill Williams River NWR supports diverse resident fauna, and draws a variety of neotropical migratory birds, from Central and South America en route to their breeding grounds in the north.
The refuge is host to some endangered bird species, including the southwestern willow flycatcher (Empidonax traillii extimus), which nests on the refuge; and the Yuma rail (Rallus obsoletus yumanensis) which lives in the marsh's broadleaf cattail colonies, and is endemic to the Lower Colorado River Valley.
