Commercial thinning young growth forests is an increasingly
important silvicultural technique for improving second growth
management of Douglas-fir stands. Research aimed at advancing the
efficiency of skyline logging operations in small wood timber stands
is essential in order to make thinning these young stands economical.
The purpose of this study...
Intensive forest management requires efficient logging techniques
to remain economical. Commercial thinnings and shorter
rotations increase piece count inversely to piece size. Continued
research aimed toward effective log handling processes is essential.
The purpose of this study was to evaluate one case of a self-loading
log truck (integral loader and...
