Preservation of Native Bull Trout in Glacier National Park: Continued Experimental Suppression of Non-native Lake Trout in Quartz Lake, Glacier National Park. 2010 Summary Report
D’Angelo VS, Muhlfeld CC, Miller BJ, Fredenberg CR. 2011. Preservation of Native Bull Trout in Glacier National Park: Continued Experimental Suppression of Non-native Lake Trout in Quartz Lake, Glacier National Park. 2010 Summary Report. USGS. West Glacier, Montana
This progress report includes results from the spring and fall 2010 sampling periods at Quartz Lake in Glacier NP. The intent of this study is lake trout control to protect bull trout habitat. The decline of threatened bull trout Salvelinus confluentus in Glacier National Park (GNP) is directly attributed to the invasion and establishment of nonnative lake trout Salvelinus namaycush from Flathead Lake, which consistently displace bull trout in systems where they have been introduced. This research project was developed to aid in the development of an action plan by experimentally assessing the feasibility of reducing the nonnative lake trout population in Quartz Lake. The goals of this four-year research (2009-2012) project are to assess the demographics of the lake trout population, and use this information to inform and implement experimental removal and control alternatives to reduce or eliminate competitive interactions in the Quartz Lake system and other lakes in GNP. This progress report includes results from the spring and fall 2010 sampling periods.
