Runoff was measured on paired litter-removed, litter-left plots in an 11-year-old European larch plantation. On five of the six pairs of plots, the plot with the litter left intact yielded more runoff. however, the differences were neither statistically nor hydrologically significant.

Careless planting was found to be the most important of several possible causes of excessive mortality of newly planted red pine. Distribution procedures and high shoot/root ratios were also implicated.

Discusses processing and conditioning treatments before and aftger compression debarking of western hemlock, Douglas fir, red alder, and bigleaf maple. Bark removal and wood recovery from red alder far exceeded the other species tested. Approximately 90 percent of the wood fiber input was recovered at a residual bark content of less than 2 percent by weight.

Reports the various applications and average costs of prescribed burning in the Central Lake States during 1972.

Red pine seedlings were grown in nine different soil media and in two types of containers in a greenhouse. Growth differed significantly among the media after 16 weeks, with the largest seedlings produced in a peat-vermiculite mix

Recent changes in the behavios of factors influencing the Lake States roundwood pulpwood market indicate there is potential for change within the pulpwood market. Softwood roundwood pulpwood production could increase at an annual rate of near 2 percent, while all roundwood pulpwood production could moderate to an average annual rate of near 1 percent over the short-tern run.
