    Assessment of Carbon Flows Associated with Forest Management and Biomass Procurement for the Laskin Biomass Facility
    (University of Minnesota, 2008-11-22) Domke, Grant M.; Ek, Alan R.; Becker, Dennis R.; Espeleta, Javier F.; D’Amato, Anthony W.; Reich, Peter B.; Suh, Sangwon; Kilgore, Michael A.; Current, Dean A.; Hoganson, Howard M.; Burk, Thomas E.; Blinn, Charles R.
    This carbon life cycle analysis of forest-derived biomass was developed as part of a larger assessment by Minnesota Power detailing fuel supply, fuel procurement plans, and project engineering for a new 26-megawatt biomass generation facility in Hoyt Lakes, Minnesota. Forest-derived biomass is a renewable fuel that can be procured locally from forest harvest residues, mill residues, material from early thinnings and land cleaning, short rotation woody crops, brush, and urban wood waste. Energy generation from renewable fuels like forest biomass may dramatically alter the carbon balance in comparison to the use of fossil fuels like coal or natural gas. This study identifies the source and rate of carbon accumulation by tracking key inputs and outputs from forests through the conversion, regrowth and management activities over a 100-year period—the net carbon impact.

    Implementing a New Forest/Transportation Modeling System in Minnesota
    (Center for Transportation Studies, University of Minnesota, 1993-05-12) Kapple, Douglas C.; Hoganson, Howard M.
    The primary objective of this project was to apply the recently developed forest/transportation modeling system to build a better understanding of transportation related factors influencing the timber supply situation in northern Minnesota. Focus was on both the likely changes in use of the Minnesota road system by the forest products industries and the likely impact of transportation considerations on forest harvesting and wood procurement practices. Of particular interest was the specific wood procurement zones for major Minnesota markets and changes in those zones over time. An important element in addressing these considerations is the dynamic nature of the timber supply situation; even without changes in timber demands, current descriptions of wood shipment patterns may be poor estimates of future patterns as forest conditions can change substantially over time. In simple terms, harvesting generally occurs in the older timber stands and the location of the older stands changes over time. One might expect a cycle in timber transportation costs as low-cost stands close to the market are likely harvested first and will not be available again until regenerated trees are of harvestable age.

    An integrated forest planning model : an overview.
    (University of Minnesota, 1989-10) Rose, Dietmar; Hoganson, Howard M.; Pelkki, Matthew H.; Arthaud, Greg J.
    A prototype of an integrated planning package for use on microcomputers has been completed. Individual components of the integrated model can be used as stand-alone modules to serve specific aspects of forest planning. Each module is documented with a user's manual and has on-screen help menus. The microcomputer-based system facilitates the development of optimal operational and strategic forest plans. The automated stand prescription writer utilizes a silvicultural expert system for Lake States species to automate the process of developing stand-level alternatives over a full planning horizon. Another program translates these silvicultural alternatives into economic cashflows, reflecting the costs of carrying out the activities. These cashflows become the input into the second module, a management scheduling model based on the Hoganson-Rose algorithm.

    Sustaining Timber Harvesting and Older Forest Conditions: A Harvest Scheduling Analysis for Koochiching County's 2010 Forest Plan
    (University of Minnesota, 2010-08-01) Hoganson, Howard M.; Reese, J. Luke
    Analyses were developed to help support the forest planning effort of the Koochiching County Land Department. Emphasis was on comparing scenarios describing plausible management strategies for five forest cover types: (1) aspen, (2) Balm of Gilead, (3) lowland spruce, (4) spruce-fir, and (5) tamarack. These cover types were not analyzed independently, as it was assumed that the annual harvest area, across cover types, is limited by the county's forestry budget. A harvest-scheduling model was applied using a 100-year planning horizon and 5-year planning periods. Analyses used the county's most recent forest inventory information, with results providing scheduled management actions for individual stands. Growth projections to estimate yields for alternative rotation lengths utilized information from a recent Minnesota Department of Natural Resources (MNDNR) study that analyzed Minnesota's wood supply potentials. Average stumpage prices received by the county in late 2009 were used in the objective function of the model that estimated the net present value (NPV) from timber returns. Stumpage prices for aspen have been higher in 2010. NPV estimates were updated to examine impacts of these higher prices. Initially, analyses examined all nine combinations of three alternatives describing general forest regulation policies by three alternative target levels for the area of the aspen cover type to sustain over time as older aspen (age 55 to 74 or age 55+ aspen). An Initial Benchmark run was developed to help understand the opportunity costs of the scenarios. Modeling results were reviewed by the county’s Forest Planning Advisory Group, with that group requesting analysis of ten additional scenarios. Four of these scenarios (Regulation Alternative G scenarios) allowed 40-year rotations in the aspen cover type. Two unconstrained benchmark scenarios were also considered that included no management constraints. The benchmark runs varied only in terms of the minimum rotation age assumed for aspen (40 years or 45 years). Substantial effort was also placed on modeling a scenario developed earlier for the county by an outside consulting firm. Scenarios were also developed that produced more age 55+ aspen when such conditions are less costly to produce (Scenarios E and Gvariable).
