“ Western toads are often found basking on rocks and logs at the edge of water in the spring and early summer, while at other times of the year they are found farther from the water spending much of their time in moist terrestrial habitats. ”

“ Western toads eat a wide variety of invertebrates. Tadpoles consume algae and detritus, including the scavenged carrion of fish and other tadpoles.
Reproduction
In the Santa Monica Mountains and Simi Hills, mating and egg­laying generally occur in the early spring after the winter rains. Adults migrate from their moist terrestrial habitats to wetland breeding areas using scent cues to find their way. Egg­laying takes place in still or barely moving waters of seasonal pools, ponds, streams, and sometimes in shallow puddles on the road. ”

“ Though there are no significant conservation concerns for this species in California, they are listed as a park species of concern. Toads are slow­-moving and are frequently run over by traffic as they cross roads at night during their breeding migrations. ”
