The Department of Forest Resources Staff Paper Series is an internal publication, many are refined later as journal articles or other forms of publication. For this reason, and due to publication costs, we do not maintain a mailing list nor do we have an excess supply. The University of Minnesota Natural Resources Library does maintain a complete file.

Item 2010 Outlook for Forest Biomass Availability in Minnesota: Physical, Environmental, Economic, and Social Availability(University of Minnesota, 2010-10) Becker, Dennis R.; Klapperich, Jonathan J.; Domke, Grant M.; Kilgore, Michael A.; D’Amato, Anthony W.; Current, Dean A.; Ek, Alan R.The growing interest and investment in forest biomass for energy production in Minnesota has created the need for accurate estimates of supply. This report estimates the total physical supply of residual forest biomass in Minnesota using a spreadsheet based Forest Age Class Change Simulator (FACCS) to model changes in forest growth and productivity at different harvest target levels, biomass retention levels, forest type, ownership, and biomass attribute (e.g., bolewood, limbs and tops). The findings are presented statewide and by region for different harvest levels and forest management scenarios. Total economic and social availability are further modeled for private woodland owners to determine the probability of their willingness to sell biomass in conjunction with ongoing forest management activities. The results provide a transparent analysis of biomass availability that illuminates policy dialogue and planning regarding the incremental increases in demand for forest biomass and the level of production that is ecologically sustainable within an area.Item A.C.E., Allowable Cut Evaluation : a microcomputer program for determination of allowable cuts : user's manual.(University of Minnesota, 1986-01) Rose, DietmarItem ACES Allowable Cut Evaluation Simulator : a microcomputer program for determination of allowable cuts for a MacIntosh computer : version 1.0 user's manual.(University of Minnesota, 1989-05) Rose, Dietmar; Johnson, Dave; Pelkki, Matthew H.Item ACES, version 5.3 : an allowable cut simulation microcomputer program : user's manual.(University of Minnesota, 1994-07) Rose, DietmarItem ACES, version 6.6 : a revised allowable cut simulation microcomputer program : user's manual.(University of Minnesota, 1995-04) Rose, DietmarItem ACESDB, version 3.3 : an allowable cut simulation microcomputer program with stand-level treatment constraints : relational database version : user's manual.(University of Minnesota, 1996-01) Rose, DietmarItem ACESREDP, Version 2.6: An Allowable Cut Simulation for Red Pine with Thinning Options Microcomputer Program: User's Manual(University of Minnesota, 1991-05) Rose, DietmarItem ACRONYM : a hierarchical tree and forest growth model framework.(University of Minnesota, 1998-03) Robinson, Andrew P.; Ek, Alan R.ACRONYM is an extensible tree-level forest growth and dynamics model framework for the synthesis and assessment of models and submodels of forest ecosystem processes. The framework is designed for research in forest ecology and silviculture, development and testing of silvicultural guidelines, forest inventory updates, and long-term projections of forest and landscape dynamics. The framework accepts modules (submodels) of forest regeneration, tree growth, mortality, silviculture, harvesting and natural disturbance, each of which may operate at different spatial or temporal scales and levels of resolution. Component modules can range from empirical to process based, as understanding and data permit. Modules can be interchanged with a minimum of reprogramming to allow for comparison of assumptions about processes, different data input protocols, and project-specific reporting requirements.Item Action, society and nature : communicative ethics and the practice of ecological economics.(University of Minnesota, 1991-07) Lewis, Bernard J.Item Allochthonous litter, carbon and element loading to Thrush Lake, Minnesota : a component of an empirical model to predict lake response to lime treatment and reacidification.(University of Minnesota, 1992) Holm, C.

The CFI on the property was established in 1959 and plots have since been measured five additional times. Summary tables are presented for individual covertypes and for covertype aggregates, for all measurement years. Trends in covertype acreage, growing stock, age class, and size class distribution for the forest over the 31-year period are also discussed. This study was conducted using an Rbase 4.5 relational database on a PC. A description of Rbase command files developed and used in the study and necessary editing and changes made to the database are included as appendices.Item Annotated bibliography of the economic implications of managing nonpoint forestry sources of water pollutants.(University of Minnesota, 1982-03) Miles, Patrick D.Item Application of James-Stein and empirical Bayes procedures to simultaneous estimation problems in forest inventory(University of Minnesota, 1980-03-01) Burk, Thomas E.; Ek, Alan R.Traditional estimation procedures may ignore available auxilary information or use it only for regression, stratification, or in survey design. Such information, however, can be incorporated directly into estimation procedures. One case that has received much recent attention is where there exist K > 4 groups of simultaneous interest which are homogeneous (similar) with respect to their means. This paper describes two approaches (estimators) which incorporate auxilary information and thereby improve estimation efficiency as compared to commonly applied normal theory maximum likelihood estimators. Computer programs for implementation of the estimators are also described. Forest inventory problems provide an ideal application for such estimators. Simulation tests were conducted on four real forest populations covering volume and area estimation. Analysis of results showed consistent reductions in estimator total mean squared error. Confidence interval analyses are also presented.Item Application of wood ash, biosolids, and papermill residuals to forest soils : a review of the literature.(University of Minnesota, 2001-07) Matysik, Molly A.; Gilmore, Daniel W.; Mozaffari, Morteza; Rosen, Carl J.; Halbach, Thomas R.Item Applications of small-scale forest harvesting equipment in the United States and Canada.(University of Minnesota, 2000-03) Updegraff, Karen; Blinn, Charles R.Item An approach to regional land cover classification in the Upper Great Lakes States.(University of Minnesota, 2000-07) Hansen, Sonja K.; Bolstad, Paul V.; Wilson, B.

In this field study, aspen (Populus tremuloides Michx.) seedlings were planted at two forested sites (Itasca and Carlton counties) amended with treatments of biosolids, boiler ash, and inorganic agricultural fertilizers. Experimental treatments included biosolids at rates equivalent to 70, 140, 210, and 280 kg available N ha-1, two types of boiler ash (application rates based on % Effective Neutralizing Power), boiler ash plus biosolids, and an untreated control. Preliminary results are reported for soil properties, aspen seedling survival, height, and caliper. Soil pH decreased with increased N application from both biosolids and fertilizer sources, but increased through additions of boiler ash and lime. Soil P increased with increased biosolids and ash application rates. Soil K increased with ash and K fertilizer applications. No differences were detected in aspen seedling survival among treatments at the conclusion of the first and second growing seasons at either installation. Height differences among treatments were detected through ANOVA in 2000 and 2001, but were inconclusive. Aspen height and caliper growth in Carlton County was greater than in Itasca County.Item Assessing State Timber Sale Policies, Programs and Stumpage Price Drivers(University of Minnesota, 2010-05) Brown, Ross N.; Kilgore, Michael A.; Blinn, Charles R.; Coggins, Jay; Pfender, CatherineThe recent major decline of Minnesota’s timber stumpage market has raised growing concern about the policies, procedures, and contract provisions associated with Minnesota’s public land timber sale programs, in particular those that apply to timber sold from state-administered forest land managed by the Minnesota Department of Natural Resources (MN DNR). In its December 2006 report, Governor Pawlenty’s Task Force on the Competitiveness of Minnesota’s Primary Forest Products Industry (Governor’s Forest Products Task Force) identified timber sale policies and procedures as one of the most urgent economic issues facing the state’s wood products industry. Specifically, the report recommended a study be undertaken to assess how state timber sale procedures and associated conditions impact stumpage prices. This report describes several research studies undertaken to address the important information needs identified in the Governor’s Task Force Report.Item Assessing the financial effects associated with implementing Minnesota's timber harvesting and forest management guidelines.(University of Minnesota, 2000-09) Blinn, Charles R.; Taff, Steven J.; Thompson, Michael J.; Mlinar, Marsha; Townsend, Neil
