The HCR (Harvest Cost-Revenue) Estimator is engineering and financial analysis software used to evaluate stand-level financial thresholds for harvesting smalldiameter ponderosa pine (Pinus ponderosa Dougl. ex Laws.) in the Southwest United States. The Windows-based program helps contractors and planners to identify costs associated with tree selection, residual handling, transportation of raw materials, and equipment used. Costs are compared against total financial return for regionally based market opportunities to arrive at potential net profit. Information is used to identify per-acre cost thresholds, for contract appraisal, and for prioritizing project planning for wildfire fuel reduction treatments and forest restoration efforts.
