Book Description
"Logging costs, product yields, and harvest revenues were determined for three thinning treatments (75, 60, and 45 percent residual stocking) and clearcutting in 60-year-old cherry-maple stands. The study area was logged by a three-man crew using chain saws and a wheeled skidder. Time study and yield data indicated that production rates and costs were similar among the four treatments. Production rates ranged from 18.5 to 19.3 c units per day, depending on the treatment. Total logging costs, including felling, bucking, skidding, loading, hauling, and roads, ranged from $44 to $35 per c unit, decreasing as the cut increased. Sawlog yields ranged from 1,621 to 13,281 board feet per acre (International 1/4-inch rule), while pulpwood yields ranged from 630 to 1,897 cubic feet per acre. Harvest revenues were sufficient to pay for roads and timber sale costs in all treatments except the lightest thinning treatment.S3.

Technoeconomic Analysis of Conventional Logging Systems Operating from Stump to Landing
Author: Raymond L. Sarles
Publisher:
ISBN:
Category : Animals in logging
Languages : en
Pages : 28
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.
