This thesis mainly consists of two parts: (1) comparing statistical modeling methods based on the area-based approach (ABA) for predicting forest inventory attributes using airborne light detection and ranging (LiDAR) data (Chapter 2), and (2) suggesting a new methodology fusing the individual tree detection (ITD) approach and the ABA for...
This study outlines a procedure to review and identify the current forest management situation and techniques employed on
the Alsea District of the Siuslaw National Forest (SNF) in
Western Oregon and compare them to the situation and techniques
employed on the Bimbo-Lobaye Forest District (BLFD) in the
Central African Republic...
The concept of forest health has recently emerged as a focal concept for federal forest policy. At the same time, social and political conflicts over the characteristics of a healthy forest, and over the causes of poor forest health, underscore the lack of a shared understanding of what the term...
Providing students with the skills necessary to identify trees is an ongoing challenge at Oregon State University. Several colleges within the university offer courses that teach tree identification. In the College of Forestry alone, two courses are offered that emphasize identification of native and introduced trees. The content and format...
Mixed-severity fire occurrence is increasingly recognized in Pseudotsuga forests of the Pacific Northwest, but questions remain about how tree mortality varies, and forest structure is altered, across the disturbance gradient observed in these fires. Therefore, we sampled live and dead biological legacies at 45 one ha plots, with four 0.10...
The issue of global climate change and an increasing interest in the reduction of fossil fuel carbon dioxide emissions by using forest biomass for energy production has increased the importance of quantifying forest biomass in recent years. The official U.S. forest carbon reporting is based on the forest biomass estimates...
This thesis investigates Contextual Teaching and Learning (CTL) as a method of instruction for natural resources education. The research follows the adoption of CTL in the K-12 classrooms of six teachers focusing on natural resources education at two rural schools in Western Oregon. CTL is being investigated because it connects...
As more people become interested in rock climbing, the need to understand climbers and their preferences and how their activities impact the resource are more vital than ever. With increased use, and with little empirical data about the Yosemite climbing community, park managers cannot adequately develop a comprehensive climbing management...
Wildfire in dry, frequent-fire forests is a pressing issue for natural resource managers, communities and politicians in the western United States. Area affected by wildfire has climbed steadily over the last twenty years and is expected to increase in the future. Recognition of the importance of both social and biophysical...
