Predicting height to crown base for undamaged and damaged trees in southwest Oregon

Creator:: Hanus, Mark L., Hann, David W., Marshall, David D., and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting height to crown base are presented for tree species from southwest Oregon. Equations for undamaged and damaged trees were estimated with weighted nonlinear regression techniques. The effects of specific damaging agents on the height to crown base were explored, and damage correction factors were estimated. The damage...

Equations for predicting the height to crown base of six tree species in the central western Willamette Valley of Oregon

Creator:: Zumrawi, Abdel Azim M. A., Hann, David W., and Oregon State University. Forest Research Laboratory
Abstract:: This paper presents equations developed to predict the height to live crown base of six species in the central western Willamette Valley of Oregon. Weighted nonlinear regression was used to fit a separate logistic equation for each species. The predictor variables are total tree height, crown competition factor in trees...

Equations for predicting height to crown base for fourteen tree species in southwest Oregon

Creator:: Ritchie, Martin W., Hann, David W., and Oregon State University. Forest Research Laboratory
Abstract:: Equations are presented for predicting height to crown base (or bole ratio) for fourteen species of trees common to the mixed-conifer zone of southwest Oregon. Nonlinear regression was used to fit a weighted logistic function for each species. The independent variables include height, crown competition factor in larger trees, stand...

Equations for predicting the largest crown width of stand-grown trees in western Oregon

Creator:: Hann, David W. and Oregon State University. Forest Research Laboratory
Abstract:: Largest crown width (LCW) equations for stand-grown trees were developed for 14 tree species found in western Oregon. The equations are used in the growth-and-yield model ORGANON and in the stand-visualization program VIZ4ST. They were constructed such that LCW equals the maximum crown width of open-grown trees when the crown...

Confessing Ireland : the colonial politics of Irish Catholicism in James Joyce's A portrait of the artist as a young man

Creator:: Rathert, Gregory S.
Abstract:: Ireland's Catholic Church played an important role in the turn-of-the-century nationalism that shaped James Joyce's identity and writing; yet it also played an important part in preventing that nationalism from achieving its goals of autonomy and cultural independence. For Joyce, this was particularly evident in the dialects and thought structures...

Fire severity and vegetation response to fire in riparian areas of the Biscuit and B&B Complex Fires, Oregon

Creator:: Halofsky, Jessica E.
Abstract:: Fire is the dominant disturbance process in western U.S. forests, and although effects of fire in upland forests are relatively well-studied, there is little information about fire effects on riparian forests, critical areas of the landscape for both habitat and water quality. This dissertation examines different aspects of fire effects...

Iroquois of the Pacific Northwest fur trade : their archaeology and history

Creator:: Jameson, Jennifer E.
Abstract:: During the early 19th Century, the fur trade brought many Iroquois to the Pacific Northwest as working primarily as voyageurs for the North West Company. When the North West Company merged with the Hudson's Bay Company, the Iroquois employees merged as well. After retirement, some settled in the Willamette Valley...

Microwave extraction of peppermint oil and comparison to the currentpractice of steam extraction

Creator:: Velasco, Carmen A.
Abstract:: The increase of diesel fuels and natural gas has increased the energy cost of the mint oil extraction industry in the Willamette Valley. In this study the energy evaluation of a distillation facility in Oregon is considered. Solvent free microwave extraction of peppermint oil is introduced as a new technique...

Equations for predicting height-to-crown-base, 5-year diameter-growth rate, 5-year height-growth rate, 5-year mortality rate, and maximum size-density trajectory for Douglas-fir and western hemlock in the coastal region of the Pacific Northwest

Creator:: Hann, David W., Marshall, David D., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Using existing permanent research plot data, we developed equations for predicting height-to-crown-base (HCB), 5-yr diametergrowth rate (delta D), 5-yr height-growth rate (delta H), 5-yr mortality rate (PM), and the maximum size-density trajectory for Douglasfir and western hemlock in the coastal region of the Pacific Northwest. With the exception of the...
