Soil surface effects on soil water, soil temperature, and Douglas-fir seedling injury following radiation frost damage events

Creator:

Melton, Lisa L.

Abstract:

A microclimatology study was conducted on a high elevation clearcut near the summit of Mt. Ashland in southwest Oregon to evaluate the effects of frost on Douglas-fir seedling growth and survival. Frost and low temperatures cause seedling stress through frost damage, frost desiccation, increased root resistance, and decreased rates of...

Douglas-fir seedling injury following radiation frost damage events AN ABSTRACT OF THE THESIS OF Lisa L
Measured and modeled energy balance parameters to evaluate the environmental conditions of reforestation

Creator:

Flint, Alan L.

Abstract:

In order to develop three models for use in quantifying the environmental conditions of reforestation, extensive measurements required for energy balance calculations were taken for a reforestation site in southwest Oregon. The models are used to decrease the number of measurements required to properly evaluate the potential for heat or...
