Invasion of the Trout

From Roman times to expansion of the British Empire in the mid-1800s, to the brown trout’s introduction to North America in the 1880s, trout have “traveled to places no trout swam before,” writes Cathy Newman, often unbalancing native species. However, fisheries biologist Stephen Moore has been working for decades to restore populations of native brook trout within Great Smoky Mountains National Park.  Via National Geographic.
