BC List Status:
Yellow (Not at risk of extinction)
Juvenile toads (“toadlets”) could be confused with the juvenile Northern Red-legged Frog or Coastal Tailed Frog, especially where distribution of these species overlaps. Western Toad tadpoles have been found associated with fast flowing streams similar to those utilized by Coastal Tailed Frog tadpoles, which can also be black and similar in size in early stages of growth. Rearing in flowing water habitats, while unusual, may reflect localized adaptations by some Western Toad populations.
Habitat loss and alteration due to urbanization and forest activities. Distribution coincides with areas undergoing rapid development.
Extirpation of local populations due to fragmentation or alteration of habitat connectivity between breeding areas and upland seasonal nonbreeding habitat.
Alteration of microclimate regimes and hydrological regimes in riparian and upland forest areas used for dispersal, foraging and overwintering due to forestry and other resource extractive activities.
Vehicle mortality and population fragmentation due to roadways that cut through core habitat areas, or migration corridors that lack appropriately sighted exclusion fencing and amphibian or wildlife passage structures.
Increased predation and competition through augmentation or stocking of sport fish (e.g. trout), and introduction of nonnative fish species, especially into non-fish bearing amphibian breeding sites.
Cumulative impacts from disease. In particular Chytridiomycosis caused by the chytrid fungus Batrachochytrium dendrobatidis and linked to dramatic population declines of amphibian species in western North America.
Direct mortality or sub-lethal impacts from fertilizer and pesticide applications in urban and agricultural areas as well as for silviculture management.
Alteration of wetland habitat from vegetation and hydrology shifts from climate change.
Apply conservation and management objectives as set out in the Management Plan for the Western Toad (Anaxyrus boreas)in Canada (2016) and “Best management practices for amphibians and reptiles in urban and rural environments in British Columbia”. Integrate complementary objectives, recommendations and assessment methods found in the “COSEWIC assessment and report on the western toad Bufo boreas in Canada” and “Research priorities for the management of the Western Toad, Bufo boreas in British Columbia.” Inventory and monitoring resources include standardized methods (Resource Information Standards Committee) # 37 Inventory methods for pond-breeding amphibians and Painted Turtle (Version 2.0), “Measuring and monitoring biological diversity - Standard methods for amphibians” and “Suitability of amphibians and reptiles for translocation”. For further details on conservation and management objectives for this species, please consult the above noted resources, references provided or contact provincial and federal agencies.
This species is listed under the Federal Species At Risk Act (SARA) and is subject to protections and prohibitions under the BC Wildlife Act. Habitat for this species may also be governed under provincial and federal regulations including the Fish Protection Act and Federal Fisheries Act as well as Regional and local municipal bylaws.
