A study of the effect of these systems on factors influencing jack pine regeneration was made in the summer of 1969 at the University of Minnesota Forest Research Center at Cloquet. This report describes the residual site conditions existing after the final harvest of a mature jack pine stand by each harvesting method and evaluates them according to conditions required for securing pine reproduction. It is one of a series of studies to be made on the effect of mechanized harvesting on environmental factors that influence regenerating a new forest.Item The Effect of Selected Cultural Practices on Lowland Balsam Fir Christmas Trees in Northeastern Minnesota(St. Paul, Minn. : School of Forestry, University of Minnesota, 1971-01-15) Alm, A.A.; Miles, W.R.Item Glyphosate and 2,4-D Application Over Red Pine Seedlings with Hand-Held Equipment(St. Paul, Minn. : School of Forestry, University of Minnesota, 1981-04-01) Alm, A.A.Item Growing Christmas Trees: A Guide for Minnesota and the North Central States(St. Paul, MN: University of Minnesota Extension Service, 1994) Alm, A.A.; Vogt, Carl E.; Wegner, Carl D.This guide includes the following important information for Christmas tree growers: Marketing; Selection of Planting Site; Selection of Species; Description of Species; Planning Your Plantation; The Planting Process; Site Preparation; Cultural Practices; Protecting Your Plantation; Harvesting; and Economics of Growing Christmas Trees.Item Growth and Survival of Exotic and Native Species at Cloquet, Minnesota(St. Paul, Minn. : School of Forestry, University of Minnesota, 1972-04-15) Alm, A.A.; Jensen, Raymond A.; Brown, B.A.Item Height and Diameter Variation in a Minnesota Jack Pine Seed Source Plantation(St. Paul, Minn. : School of Forestry, University of Minnesota, 1966-10-15) Alm, A.A.; Brown, Bruce A.; Jensen, Raymond A.Item Jack Pine Tubeling Trials in Minnesota Under Four Site Preparation Treatments(St. Paul, Minn. : School of Forestry, University of Minnesota, 1972-04-15) Alm, A.A.Item Mechanized Thinning of Dense Post-Fire Jack Pine Regeneration(St. Paul, Minn. : School of Forestry, University of Minnesota, 1970-12-15) Alm, A.A.; Schantz-Hansen, R.Item Production and Marketing of Douglas-Fir Christmas Trees in Minnesota(St. Paul, Minn. : School of Forestry, University of Minnesota, 1968-04-15) Alm, A.A.Item Red Pine Tubeling Survival Related to Length of Cultural Period(St. Paul, Minn. : School of Forestry, University of Minnesota, 1974-04-15) Alm, A.A.Item Results of Lake States Jack Pine Seed Source Test in East Central Minnesota(St. Paul, Minn. : School of Forestry, University of Minnesota, 1969-01-15) Alm, A.A.; Jensen, Raymond A.Item Successful Establishment of Red Pine Tubelings in Minnesota(St. Paul, Minn. : School of Forestry, University of Minnesota, 1977-01) Alm, A.A.Item Use of Herbicides in Northern Minnesota for Forestry Purposes - 1983(St. Paul, Minn. : School of Forestry, University of Minnesota, 1984-09) Alm, A.A.
