Document Summary
Two modern methods of logging are currently employed at algonquin. Both cause loss of species diversity and other damages not immediately apparent. Method 1: uniform shelterwood (us) system in the eastern white pine forest. Individual trees are removed over a 4 cut rotation. Removed in a uniform spacing pattern so that sufficient light will reach the ground to encourage white pine regeneration. Logging is performed such that land will be stripped of just 1 generation of trees over 4 sequential cuts. White pine regeneration is promoted as the surrounding area will have lots of mature white pines. The trees remaining will fill the canopy spaces left by remover, prior to the next cut, thus full blown succession is inhibited. Leaves a denser canopy than what would be produced with us, inhibiting succession even more. Seeks to regenerate shade tolerant species (hard maple) Single trees can be protected in the case of individual wildlife nesting/denning trees.
