In mid‑July 2026 residents and environmental groups in British Columbia’s Comox Valley warned that invasive American bullfrogs had become established and were threatening native wildlife, including salmon fry and ducklings. They urged municipal authorities to introduce property‑tax incentives for eradication, impose fines for non‑compliance, and launch school‑based education campaigns.

Two weeks later, tribal and state agencies in Montana’s Mission Valley wetlands issued a wanted‑poster style appeal for the same invasive species. The Confederated Salish and Kootenai Tribes, together with the Montana Conservation Corps, Fish, Wildlife & Parks, and the Invasive Species Council, highlighted the bullfrog’s impact on native amphibians and other fauna. They asked the public to report sightings via email and QR‑code flyers, aiming to halt further spread.

Both snapshots illustrate a coordinated, cross‑border response to the rapid expansion of invasive bullfrogs in North America, with local authorities and indigenous groups mobilising public‑reporting tools, regulatory measures, and outreach to protect indigenous ecosystems.
