Extended Rotation (uncut control)

Extended rotation is not a silvicultural system, but in this experiment, it provides baseline data for comparing silvicultural systems. The management objective for the area is to leave the forest undisturbed and to observe the natural processes of tree growth and mortality over the next 80 years. At that time, many of the trees will be 140 years old and may exhibit some old-growth attributes that will enhance biodiversity, wildlife habitat, and aesthetic values.
