Montana removed non-native brook trout and repaired mining-damaged White's Creek; the struggling native cutthroat trout population then grew at least sevenfold

In White's Creek, Montana, a dedicated conservation project took shape to safeguard the native westslope cutthroat trout from the encroachment of non-native brook trout. By utilizing habitat restoration techniques and electrofishing for brook trout removal, researchers observed a dramatic rise in the trout population, climbing from approximately 80 to over 340 within just a few years.
