Creator:: Martinez Ben, Jesus
Abstract:: A set of 119 study trees was identified in a 65 year-old Douglas-fir stand after a thinning operation conducted seven years ago using pre-planned skid trails and groundbased machinery. Some of the trails were tilled using a winged subsoiler after this operation in order to alleviate the effect of compaction...

Creator:: Zaborske, Richard R.
Abstract:: The use of mechanized harvest equipment has been increasing as an economical method to harvest small diameter timber. While the use of this equipment is increasing, little is known about associated soil compaction. In particular, little information exists on soil compaction caused by feller--bunchers. This study measured soil compaction caused...

Creator:: Nuss, Meagan Louise
Abstract:: Oregon has been moving forward with biomass energy development. Large-scale biomass power and cogeneration (producing heat and electricity) have been the focus of the last twenty-five years, while small-scale thermal bioenergy installations (producing heat) have dramatically increased during the last decade. In eastern Oregon, bioenergy is closely linked to restoration...

Creator:: Ito, Yuzuru, 1958-
Abstract:: The success of civil engineering construction in cold regions often depends on the assessment of the potential for frost heave. Over the past two decades two models have been presented to the engineering community to identify the frost heave potential, namely: (1) the segregation potential (SP), and (2) the discrete...

Creator:: Clark, Joshua Andrew
Abstract:: The importance of accurately identifying inventories of domestic energy, including forest biomass, has increasingly become a priority of the US government and its citizens as the cost of fossil fuels has risen. It is useful to identify which of these resources can be processed and transported at the lowest cost...

Creator:: Ayele, Zeleke Ewnetu
Abstract:: Past afforestation programs launched to promote private and community woodlots in rural Ethiopia have not been based on clear understanding of the incentives and constraints of smallholder farmers. This study investigated the characteristic differences between tree-growing and non-tree-growing farm households and identified factors influencing farmers’ tree-growing decisions from a farming...
