The Crown of the Continent Research Learning Center at Glacier National Park is hosting a brown-bag luncheon presentation on a recent graduate study that evaluates the feasibility of suppressing invasive lake trout in remote backcountry lakes in order to maintain healthy native bull trout populations. The free presentation is Tuesday, March 10, from 12 p.m. to 1 p.m. at the park’s community building in West Glacier.
Glacier National Park Fisheries Biologist Carter Fredenberg will present recent research that examines the effectiveness of suppressing invasive lake trout in Quartz Lake, both in terms of reducing the lake trout population and the effects suppression has on the native bull trout population. The study was conducted in partnership between Glacier National Park and the US Geological Survey.
Carter received a Bachelor of Science Degree in wildlife management with an aquatic emphasis in 2009 from the University of Montana, and a Master of Science Degree in fish and wildlife management from Montana State University in 2014. Carter spent seven years with the US Geological Survey as a fisheries technician in Glacier National Park, and recently joined the National Park Service as a fisheries biologist to aid park staff in monitoring and managing the park’s aquatic resources.
