Book Description
S2A technoeconomic analysis of timber harvesting systems was conducted to obtain key information for estimating long run supply trends of roundwood materials from eastern woodlands. Productivity and cost factors for six stump-to-landing systems were developed from operational data for 47 harvesting operations. Technical factors and the effects of financial considerations were also assessed. Combined with the productivity and cost factors, they provided better perception of the forces impacting long run roundwood supplies and logging contractors' business options.S3.
