CSISS has recently completed a risk assessment for the invasive American Bullfrog. Bullfrogs are not currently known in the Columbia Shuswap region, but populations exist in Creston, the Lower Mainland, and on Vancouver island. The assessment looks at the the most likely pathways of introduction of this highly invasive species, the best preventative measures to take, and the potential risks and costs if such an introduction were to occur.
