Understanding brook trout in Idaho high country bull trout streams

Non-native brook trout were introduced to Idaho more than 100 years ago, and since that time, they have found a home across many drainages in the state. While having brook trout in some places makes for a great day fishing, in others, they threaten an iconic Idaho native, the bull trout. Brook trout have the capability to outcompete and cross-breed with bull trout which is not a good thing.
