An examination of several methods of quantifying forest structure in headwater riparian forests of western Oregon

Creator:: Haxton, Zane A.
Abstract:: Headwater streams are generally small, first-order streams that can comprise up to 80% (by stream length) of the drainage network in mountainous areas of the Pacific Northwest. These streams are intimately connected with downstream reaches, serving as a source of sediment, woody debris, organic matter and nutrients. The surrounding forests...

Measuring your trees

Creator:: Bowers, S. (Steven Clay), Reeb, J. E. (James Edmund), 1951-, Parker, Robert, 1941-, and Oregon State University. Extension Service
Abstract:: Procedures outlined in this publication show how to estimate standing volume and annual growth of individual timber stands that are relatively uniform in species, age, size, and density. Estimates of volume and growth are helpful in planning when to harvest or how much to remove in a thinning operation. These...

Comparison and analysis of small area estimation methods for improving estimates of selected forest attributes

Creator:: Goerndt, Michael E.
Abstract:: One of the most common practices regarding estimation of forest attributes is the partitioning of large forested subpopulations into smaller areas of interest to coincide with specific objectives of present and future forest management. New estimators are needed to improve estimation of selected forest attributes in small areas where the...

Examination of imputation methods to estimate status and change of forest attributes from paneled inventory data

Creator:: Eskelson, Bianca N. I.
Abstract:: The Forest Inventory and Analysis (FIA) program conducts an annual inventory throughout the United States. In the western United States, 10% of all plots (one panel) are measured annually, and a moving average is used for estimating current condition and change of forest attributes while alternative methods are sought in...

Accuracy and suitability of several stand sampling methods in riparian zones

Creator:: Marquardt, Theresa
Abstract:: Stand structure in headwater riparian areas of western Oregon is highly variable making quantification of structural attributes within these stands difficult. A reliable sampling design is important to characterize and monitor changes in stand structure over time. This study examined sixteen alternatives for sampling live conifers and six alternatives for...

Ecological thresholds, climate extremes, and tree species' distributions across the Pacific coastal United States

Creator:: Lintz, Heather E.
Abstract:: Species' distributions across the landscape are perhaps the least understood yet most conspicuous features of life on earth. Ecologists have long studied species' distributions; yet, many questions remain about why species occur where they do. Such questions persist largely because species' distributions are complex systems with challenging properties like non-linearity,...

Forest biomass estimation with hemispherical photography for multiple forest types and various atmospheric conditions

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...

The methodology, implementation, and analysis of the isotopic composition of soil respired CO₂ in forest ecological research

Creator:: Kayler, Zachary Eric
Abstract:: Soils are the largest terrestrial pool of carbon, therefore it is critical to understand what controls soil carbon efflux to the atmosphere in light of current climate uncertainty. The primary efflux of carbon from soil is soil respiration which is typically categorized into autotrophic and heterotrophic respiration. These two components...

Incremental cores of the National Forest Inventory from Romania

Creator:: Strimbu, Bogdan and Marin, Gheorghe
Abstract:: Dendrochronological data provides insight in the tree development, and used in conjunction with forest inventory, can supply inputs for growth and yield modeling. However, accurate and precise measurements of a large number of incremental cores require significant resources. One possible source of valuable tree ring data are national forest inventories...
