Abstract

The PP PRUNE program allows users to conduct a financial analysis of pruning ponderosa pine (Pinus ponderosa Dougl. ex Laws.). The increase in product value and rate of return from pruning the butt 16.5-foot log can be estimated. Lumber recovery information is based on actual mill experience with pruned and unpruned logs. Users supply lumber prices by grade, the cast of pruning, and tree descriptions from growth and yield information. The program estimates the difference in value for trees and stands with and without pruning and the difference in present net worth from adding pruning to a given regime.The Lotus 1-2-3spreadsheet program was used to develop PP PRUNE. Users need a basic knowledge of spreadsheets to use this program.
