| Abstract: |
The Map Analysis Package was used to construct maps of maximum potential stumpage (MPS) for an 3,800 acre forest in central New York. NIPS is the maximum difference between the mill delivered price of forest products and the cost to harvest them and can be used as a guide in the establishment of forest management plans. MPS was generated from maps of Market Value (MV), Cost to the Landing (CL), and Cost to the Mill (CM). MV maps were created from a compartment map which was modified to show market value by multiplying wood volume by mill delivered price of sawlogs and roundwood. CL map is a map of the cost of skidding products from the stump to the roadside. Skidding costs were generated from slope, soil, stream, and roadway maps. CM depicts the cost of transporting the products from roadside to the appropriate mill. Thus MPS=MV-CL-CM. The MPS map agreed with the forest manager's perception of which compartments would have been the most profitable to harvest at that time. The ability to incorporate changes in price and costs and re-run the analysis make the procedure a useful forest management decision support system. |
