Abstract: This project will implement a medium-scale (10 acres/year) field trial of the indigenous fungus Mycoleptodiscus terrestris for treatment of Eurasian watermilfoil in the Les Cheneaux archipelago in northern Lake Huron. Treatment outcomes as well as longer-term effects of previous releases of both the fungus and the milfoil weevil Euhrychiopsis lecontei will be evaluated using field surveys and multi-scale remote sensing and image classification across an approximately 800-acre area. The project will help preserve public recreational opportunities in an area where they have high economic value and improve ecosystem function by restoring and retaining native aquatic vegetation species.
