Modeling Forest Trees and Stands

Transportation planning is an important part of the wood flow chain in forestry. There are often several forest companies operating in the same region and co-ordination between two or more companies is rare. However, there is an increasing interest in collaborative planning as the potential savings are large, often in the range 5-15%. A key question is how savings should be distributed among the participants. In this paper we investigate a number of possibilities based on economic models including Shapley value, the nucleolus, separable and non-separable costs, shadow prices and volume weights. We also propose a new allocation method based on finding as equal relative profits as possible among the participants. A case study including eight forest companies is described and analyzed.

The Total-Tree Multiproduct Cruise Program is a user-friendly, interactive computer program that uses standard tree-cruise data to estimate the weight and volume of the total tree, saw logs, plylogs, chipping logs, pulpwood, crown firewood, and logging residue in timber stands. Input is cumulative cruise data for tree counts by d.b.h. alone or by d.b.h. class and total height, height to 4-inch top, or saw-log merchantable height for individual species or species groups. Output is in tables: (1) board-foot volume by d.b.h., (2) total-tree and tree-component biomass by d.b.h. class. (3) a suannary table, and (4) projected annual growth by stand component and species. Output can be expressed in tons, cords, cunits. or board feet per acre, or by cutting units and tract totals; The program is written in FORTRAN V for a mainframe and in PASCAL for the IBM-PC microcomputer. This manual describes the program and how to enter cruise data to obtain desired output for both the mainframe and microcomputer versions.
