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.

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 County forestry activities: a survey of programs in selected states(University of Minnesota, 1980-04) Baughman, Melvin J.; Ellefson, Paul V.Item Brief description of MFPS: a multipurpose forest projection system.(University of Minnesota, 1980-05) Ek, Alan R.; Rose, Dietmar; Checky, Michael T.Item Bibliography of worldwide literature on individual tree based forest stand growth models(University of Minnesota, 1980-05-25) Dudek, Albert; Ek, Alan R.Item Plot, stand, and covertype aggregation effects on projections with an individual tree based stand growth model.(University of Minnesota, 1980-07-07) Moeur, Melinda; Ek, Alan R.A distance-independent individual-tree-based growth model (MFPS) was used to project changes in stand structure on aspen, red pine, and jack pine covertypes in northern Minnesota for 37 years. Individual .058 ha plot projections, projections of plots aggregated within stands, and projections of plots aggregated within covertypes were compared to each other and to observed plot conditions. Actual plot observations were available for up to 17 years. Individaul plot, stand, and covertype aggregations produced very similar projections in terms of number of trees, average diameter, basal area, and biomass. Plot by plot projections were most accurate in comparison with observed conditions, followed by stand and then covertype aggregations. Differences from actual values and among projections generally increased with longer projections.Item Development of individual tree based stand growth simulators : progress and applications.(University of Minnesota, 1980-08) Ek, Alan R.; Dudek, AlbertResearch since the early 1960's on the development of individual tree based stand growth simulators is reviewed with respect to evolving methodologies for treating overstory growth, competition, mortality, reproduction, stochastic errors, calibration, and validation. The present and potential accuracy and precision of the models is discussed along with applications to date. Strategies for using the models for succession analysis and decision-making regarding choices among management treatments are also considered. It is apparent that these models can be expensive to develop, but represent one of the most powerful approaches available for predicting forest change. They are also a convenient basis for forest managers and ecological scientists to work together effectively. Pitfalls in the process of model development and usage are also discussed.Item County-administered forestry programs in Minnesota: a review of administrative structure and procedure.(University of Minnesota, 1980-09) McCann, Brian D.; Ellefson, Paul V.
