Comparing Pine Regeneration Methods and Tactics in the Cloquet Valley State Forest (MN DNR)

The goal on all three stands was to decrease the overall abundance of trembling aspen, paper birch, and balsam fir while increasing the abundance of long-lived conifers such as red pine, white pine, white, and black spruce.
