The anuran family Bufonidae is a large, cosmopolitan group comprising of almost 400 species that inhabit a great variety of environments. Three bufonids with relatively limited distribution in the United States are federally listed as “endangered”: Wyoming toads (Bufo baxteri), arroyo toads (B. californicus), and Houston toads (B. houstonensis). Golden toads (B. periglenes) from Central America are perhaps the best known example of an anuran that has recently declined. Twenty-one bufonid species are recognized in the United States, and eleven of these occur in the arid Southwest. Although most of the desert dwelling forms have not been surveyed in any detail, a number have been superficially inventoried. This chapter reviews what is known about the status of bufonids of the arid southwestern United States and draws attention to emerging general patterns regarding their status. It looks at the spring breeding of Arizona toads in perennial streams, as well as the summer breeding of Sonoran green toads in rain-formed pools.
