Why Are Brook Trout Important

Brook Trout (Salvelinus fontinalis) are the native cold water char in Eastern North America. Survival relies on temperatures below 20°C and pristine water quality. Brook Trout are in decline due to urbanization, over harvest, water pollution, climate change, invasive species, groundwater extraction, dam construction, habitat fragmentation and degradation.
