Creator:: Gleason, John F.
Abstract:: Two-year-old ponderosa pine (Pinus ponderosa Laws.) from two seed sources were grown at two nurseries. The Fremont seed source was raised at Bend and Stone Nursery; the Ochoco was grown at only the Bend Nursery. The seedlings were fertilized in late September-early October with nitrogen (N) or nitrogen plus potassium...

Abstract:: Two-year-old Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] seedlings of two seed sources raised in three nurseries in Oregon and Washington were tested for differences in frost hardiness from September 1985 to March 1986. The objective of the study was to determine whether nursery location had an influence on seedling acclimation, deacclimation...

Abstract:: The identity and distribution of ant species preying on the western spruce budworm (Choristoneura occidentalis Freeman) was investigated in eastern Oregon and western Montana. A sticky trap was developed to index ant foraging activity in the canopy by intercepting ants falling from the tree as they traveled between canopy and...

Abstract:: A time domain simulation model which approximates the three-dimensional velocity fluctuations of wind turbulence has been developed. This model is used in a discrete time control algorithm to regulate the output torque of a wind turbine by changing the pitch angle of the turbine blade. The wind model provides a...

Abstract:: Using clones to regenerate a species new to clonal reforestation presents the forest manager with many problems. A number of interrelated and interdependent research and development activites are needed to answer these technical questions. Network diagraming was used for scheduling research activities and for indicating interdependencies among activities. The resultant...
