Glacier Park is showing good success in recovering a depleted bull trout population . . .
Glacier National Park, historically one of the last best strongholds for native bull trout, has seen its wild populations decimated by the explosion of invasive lake trout, reducing Montana’s aquatic darling to an imperiled icon and pushing the species toward the brink of extinction.
But biologists with Glacier Park and the U.S. Geological Survey have pioneered a new effort to suppress lake trout in remote backcountry lakes and reintroduce dwindling bull trout populations, with recent results showing strong evidence of success, and indicating that the efforts could be applied to other invaded habitats and broader ranges.
“New results are promising. The park is kind of spearheading these innovative and proactive ways to save bull trout,” Clint Muhlfeld, an aquatic biologist with the U.S. Geological Survey (USGS), said. “It’s been so rewarding to have our science apply to on-the-ground management and leading conservation efforts in Glacier.”
