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

Population Dynamics of Herbivorous Insects on Young-growth Douglas-fir

Purpose

Shoots to be collected during the growing season from 25 orange-flagged trees along a transect at each site. Arthropods are being identified and counted. Regressions of foliage biomass to stem diameter are being used to estimate arthropod population siz

Methods Testing for Assessment of Radial Growth in Young Douglas-fir

Purpose

Investigating factors which affect cambial phenology in Douglas-fir. My research site is several hours drive away. In the Dunn forest, intend to test methods of extracting radial wood samples from the trees using various tools (drill, plug cutter, chise
