Between 2019 and 2022, over five million amphibians and reptiles were relocated in British Columbia for construction projects, but there is no requirement to monitor their survival rates. Experts call for habitat avoidance and better monitoring practices to protect these vulnerable species.
- 01Over 5.1 million amphibians and reptiles were relocated in B.C. from 2019 to 2022 due to development.
- 02The practice of mitigation translocation lacks legal requirements for monitoring survival outcomes.
- 03Amphibians and reptiles are crucial for ecosystem health, serving as both predators and prey.
- 04Researchers advocate for habitat avoidance as a priority in development planning.
- 05Translocation should be a last resort, yet it has become a routine practice in B.C.

In British Columbia, more than five million amphibians and reptiles were relocated between 2019 and 2022 to facilitate construction projects, according to recent research. This practice, known as mitigation translocation, has been common for over a decade but lacks a legal requirement to monitor the survival of these animals post-relocation. The study, led by Megan Winand, highlights that 227 permits documented the movement of 5.1 million animals across 28 species, including frogs and salamanders. Experts emphasize the importance of these species in ecosystems, where they help control insect populations and serve as prey for various animals. They advocate for habitat avoidance as a primary strategy to prevent harm, suggesting that infrastructure should be rerouted or redesigned to protect wildlife. The authors argue that translocation should only be considered when avoidance is impossible, as current practices may lead to significant consequences for these vulnerable species without any knowledge of their survival rates after relocation.
