Supressing Invasive Lake Trout in Quartz Lake: Implications for Native Bull Trout

by Carter Fredenberg

Tuesday, March 10, 2015
Noon-1 PM
Glacier National Park Community Building

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. Quartz Lake is a remote backcountry lake located in the Northwest section of Glacier National Park. The study was conducted in partial fulfillment of Fredenberg's master's degree and was a collaborative effort between the US Geological Survey and Glacier National Park.
Carter received a BS in Wildlife Management with an Aquatic Emphasis in 2009 from the University of Montana, and a MS in Fish and Wildlife Management from Montana State University in 2014. Carter spent seven years with the United States Geological Survey as a fisheries technician in Glacier National Park, then in 2014 joined the National Park Service as a Fisheries Biologist to aid park staff in monitoring and managing the park’s aquatic resources.
