Reserve Strip Method as an Alternative for Regenerating Eastern Hemlock

Realization that eastern hemlock (Tsuga canadensis L.) provides both a good yield of softwood material and valuable cover for wildlife has increased interest in successfully regenerating this species. In the central Adirondack Mountains of New York State, the outcome is variable. The study investigated the potential to regenerate hemlock in the reserve area between clearcut strips. Data show that reserve strip widths of about two-thirds the height of overstory trees appeared best for regeneration and recruitment of eastern hemlock to taller height classes. Wider reserve strip widths allow regeneration of hemlock seedlings but inadequate recruitment to larger sizes. Poisson regression indicated that reserve strip width significantly influences the establishment of hemlock seedlings greater than 6 in. high. North. J. Appl. For. 18(3):69–73.
