Fighting An Invasive Species

Last summer, writer Carly Flandro and I spent an amazing day on Yellowstone Lake inside Yellowstone National Park. We were documenting efforts by the National Park Service to eliminate lake trout from the Yellowstone ecosystem. The lake trout, likely introduced by a “bucket biologist” in the 1980s, are non-native to Yellowstone and have been decimating populations of the native Yelllowstone cutthroat trout. So the NPS is employing its own boats as well as those of several commercial fishing outfits to catch as many of the lake trout as they can, hoping their efforts will allow the cutthroats to recover.
