| Tiivistelmä: | Analytical tools are required by forest (here as: f-t.) management planners to assess the effects of alternative strategies (here as: strs). This paper assesses the spatial patterns of alternative management strs. by linking two models developed for different purposes: 1. a linear programming model (Spectrum) to optimize timber harvest schedules and 2. a simulation model (HARVEST) to project those schedules in a spatially explicit way, and to produce maps to calculte the spatial pattern of habitat. The power of this approach is demonstrated by evaluating alternative plans developed for a national f-t. plan revision in Wisconsin, USA. There are results reported in detail. The results are consistent with the design goals of each of the alternatives. However, it is revealed that the spatial differences among the alternatives are modest. |
