Understanding the effectiveness of mitigation translocation for Columbia Spotted Frogs (Rana luteiventris) in British Columbia, Canada
Abstract
Mitigation translocation is a commonly used practice in British Columbia (BC) to protect herpetofauna from the negative impacts of human-caused habitat alteration or destruction. However, despite its widespread use, the success rates of this approach remain uncertain, particularly when compared to other types of translocations. The Columbia Spotted Frog (Rana luteiventris) is notably impacted by mitigation translocation projects in BC, and serves as the focal point of this study. Using passive integrated transponder (PIT) tags and capture-mark-recapture methods over a two-year period, I will assess post-translocation survival of Columbia Spotted Frogs that have been moved to one of three treatments: 1) control, 2) a wetland that is a short distance (> 1km) away, and 3) a wetland that is a long distance ( > 5km) away from the control. Radio transmitters will be assigned to a subset of Frogs in year 1 and tracked over 3 weeks to understand if movement patterns change post-translocation. Preliminary results from this study will be discussed. This study will fill knowledge gaps and provide valuable insights into improving the effectiveness of mitigation translocation for amphibians.
