An Experiment to Analyze Prebunching With a Low Investment Skyline Yarder as and Economical Approach to Thinning Young-growth Pacific Northwest Timber Stands

Purpose

The experiment will use each skyline road as an experimental unit. Ten units will be laid out, each 1,00 ft. by 250 ft. wide. Four units will be assigned as silvicultural control units. Two will be assigned as thinning control units and will be logged

Skyline Mechanics Study

Purpose

Summer 1985: We will be conducting static tests on the skyline corridor. Measuring skyline and guyline loadings, and tailtree deflections. Summer 1986: Dynamic tests will be conducted on the skyline corridor.

Tailtree Mechanics

Purpose

We will be rigging a short (<400'] skyline corridor and "logging" less than the equivalent of 20 trees (hardwoods mostly) to measure the dynamic behavior of the tailtree.
