Some populations persist for a few years in orchard-vineyard habitats. Scaphiopus are rarely found on the surface. Some individuals also use mammal burrows. Recently metamorphosed juveniles seek refuge in the immediate vicinities of breeding ponds for up to several days after transformation. Breeding and egg laying occur almost exlusively in shallow, temporary pools formed by heavy winter rains.
Rainfall is important in the formation and maintenance of breeding ponds.
Most surface movements by adults are associated with rains or high humidities at night. Dispersal of postmetamorphic juveniles from breeding ponds often occurs without rainfall. Grasslands with shallow temporary pools are optimal habitats for the western spadefoot. They are active on the surface nocturnally during rains or periods of high humidity. Breeding activities normally conclude by the end of March.
