Transboundary Bullfrog Control Along the Canada-U.S. Border

Since 2018, the Central Kootenay Invasive Species Society (CKISS), along with government, tribal nations, stakeholders, and international partners, has been removing invasive American bullfrogs from Idaho to BC along the Kootenay (Kootenai) River to protect Northern leopard frog habitats. Due to limited knowledge about bullfrog distribution in the Kootenay Valley, a coordinated landscape-scale approach was implemented. A Transboundary Funding Agreement was established, and by March 2021, biologists removed 2,121 bullfrogs from Creston Valley using mechanical removal and shooting. CKISS also led a community education program on bullfrog awareness, which reached over 43,500 people through 45 events in 2019.
