Description: The DFPRUNE spreadsheet program is designed to estimate the expected financial return from pruning coast Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii. It is a significant revision of the PRUNE-SIM program. The PRUNE-SIM program was based on the average product recovery for unpruned logs from a single stand that received frequent light thinnings. The DFPRUNE program incorporates new recovery information for unpruned young-growth Douglas-fir and can be used to assess the economic potential of pruning for a wide range of management regimes. Product prices and descriptions of trees at time of pruning and at time of harvest must be supplied by the user. The DFPRUNE program was developed for the Lotus 1-2-3 spreadsheet and should work on versions 2.01 or later.

Keywords: Douglas-fir, pruning, forest product value, product recovery, simulation
