Book Description
Excerpt from Natural Regeneration of Swamp Black Spruce in Minnesota Under Various Cutting Systems However, when the evidence is correlated with previous work at the Station and elsewhere, plus silvical information on the species, a pattern emerges. Any silvicultural system must provide for satisfactory regenera tion or ultimately it will fail. Of course, growth and yield of the stands, and costs and returns for the total operation are also crucial factors in choosing a cutting system. But economic decisions are only as sound as the biological information upon which they rest. This report is intended primarily as a contribution to silvicultural knowl edge of the regeneration phase of swamp spruce management.

Book Description
Excerpt from Preliminary Study of White Spruce in Minnesota The data obtained on growth, yield, and distribution of white spruce in the state have been assembled and the approximate returns which may be expected from young stands or plantations determined. Since little information on this species has been published it is thought that this study, tho not complete in itself, will be helpful to the state in its reforestation work, to the individuals who have land suited to spruce, or to corporations that may wish to grow a perpetual supply Of spruce for industrial purposes. The writer wishes to acknowledge the valuable assistance of G. H. Wiggin, A. F. Oppel, and K. J. Braden in collecting data, and of J. H. Allison who aided in the collection of data on volume studies and gave helpful suggestions on taxation principles.
