Costs of potential treatments per acre moving sawlogs with a skidder. This metric is dependent on predefined treatments or silvicultural prescriptions, which are best generated at the local and/or project level. The cost to perform each treatment given a defined prescription and should consider an array of factors including the spatial juxtaposition of the resources and infrastructure, as well as the location of the saw timber and biomass processing plants.--------Treatment cost calculations take into consideration the multiple costs necessary to move material from the forest harvest site to a processing location (sawmill or biomass facility) and includes the costs of felling, processing, skidding and hauling:--------costs to move material along different types of roads (i.e., dirt, paved, highways, etc.)--------across barriers (i.e., water courses)--------operational costs--------machine costs--------speed of moving material across the landscape.--------Cost values have been broken down into the costs to move either biomass or sawlogs.----------------This raster has been modified from the base 30m version in the following ways:-------- - It has been aggregated from a 30m to a 300m scale by averaging across the 30m values-------- - The normalized values are rescaled based on nearly the full range of actual values, with the most extreme values truncated at the 1st and 99th percentile to reduce the influence of outliers on the expressed range of normalized values, with -1 representing higher costs and 1 representing lower costs. This interpretation reflects the desire to consider costs in project design, with lower costs considered more favorable.----------------- Unit Of Measure: Dollars |
