Objectives : We compared the large-scale and longterm impacts of uneven-aged and even-aged managements on the composition, road density and fragmentation of a landscape composed of northern temperate and boreal forests, and presenting frequent forest fires. Methods : We simulated an 800,000 ha forested landscape in the Mauricie region (Quebec, Canada) over a 150-year planning horizon with the LANDISII model and an extension that simulates forest road construction. We compared 30 diffe...
