Temporary Roadside Pond Use by Western Toads

This research examines temporary roadside ponds as a breeding habitat for amphibians, including the western toad (Anaxyrus boreas). Findings will inform about the relationships between artificial ponds created via forest practices, weather, and amphibian breeding behaviour.

Project Summary

The western toad (Anaxyrus boreas) is widely distributed throughout western North America. In habitats altered by forest practices, the degredation of natural habtiat and the creation of artificial (temporary) ponds from both road construction and harvest can either benefit or hinder local populations, providing either suitable habitat facilitating growth and development, or can result in severe, mass mortality events when conditions become unfavourable.  

This project noted both pond characteristics and amphibian use over a 5-year period. Thus far, findings suggest that a majority of roadside ponds studied function as amphibian breeding habitats, especially for western toads (detected in 89% of ponds studied). However, relatively high temperatures in summer result in pond desiccation (drying up) before tadpoles have time to reach maturity.
