There is no published information on mortality of western toads from fire. No specific information describing the response of western toads and their habitat to fire was available in the literature.
Western toads are vulnerable to changes in both terrestrial and aquatic habitat.
Crown fires would reduce shade and surface humidity and decrease the amount of daylight time toads could spend active after a fire. Fires during early spring could affect egg masses by reducing shade and increasing water temperatures. Any substantial change in runoff rates, erosion, or water tables caused by fire could degrade breeding sites. It is likely that there is a change in the relative amounts of different types of prey organisms in the postfire diet of western toads. Immediately after fire, many insects are present but those requiring shade do not adapt well to the more open conditions.
