There are two known subspecies of the western toad and the ranges of subspecies are as follows:.

The range of the western toad extends from western British Columbia and southern Alaska south through Washington, Oregon, and Idaho to northern Baja California, Mexico; east to Montana, western and central Wyoming, Nevada, the mountains and higher plateaus of Utah, and western Colorado.

In the Pacific Northwest, the western toad occurs in mountain meadows and less commonly in Douglas-fir forests (Pseudotsuga menziesii).

In California, optimum habitat for the western toad includes wet or dry mountain meadows or riparian deciduous forest with available open water for breeding.

At low elevations western toads are active at night; at high elevations and in the northern parts of their range they are diurnal.

Body temperature of western toads is closely correlated with the substrate temperature.

Diurnal and nocturnal activity are often related to seasonal changes in temperature; most western toads are diurnal during the spring and fall but are nocturnal during the warmer summer months.

In central Oregon, the minimum breeding age for male western toads is three years, and probably four or five years for females.

Male western toads breed every year; females breed at less regular intervals, depending on individual condition and previous years' breeding effort.

Female western toads at least 10 to 11 years of age have been reported.

In the mountains of Colorado, the largest western toad populations usually occur from about elevation.

Under laboratory conditions western toads were able to survive in 40% seawater, but died within a week when exposed to 50% seawater.
