Amphibians

Toad, Western  | Bufo boreas

Status: Special Concern

Last Examination and Change: November 2002 (New)

Canadian Occurrence: YT, NT, BC, AB

Status Criteria: Not applicable

Reason for Designation: This species has suffered population declines and population extirpations, at least one of which is well documented. It is relatively intolerant of urban expansion and the conversion of habitat for agricultural use. Dependent upon oligotrophic and fishless ponds and small lakes for breeding, it is also sensitive to habitat deterioration, introduced exotic predators and competitors, and disease. This species remains widespread and locally abundant throughout most of its historic range in Canada despite its known vulnerabilities to urban expansion, conversion of habitat for agriculture, habitat deterioration, introduced exotic predators and competitors, and disease, all of which have severely reduced its abundance and range further south.

Status History: Designated Special Concern in November 2002.
