Survival and Height Growth of Eight Tree Species Planted in Riparian Restoration Project Areas throughout the Coos Bay, Oregon Watershed

Creator:: Law, Lucie R.
Abstract:: Riparian areas are targeted for restoration activities because of the important ecological functions these areas provide. Millions of dollars are spent on riparian restoration projects, yet little long-term monitoring data are collected to understand the growth and survival of the planted trees and shrubs after initial project establishment. With the...

Improving Forest Management in a Changing Climate with an Adaptive Management Framework: A Case Study in the Lake Tahoe Basin

Creator:: Perkins, Grant
Abstract:: Forest managers are faced with balancing a multitude of management objectives including social, economic, and ecological drivers as well as the uncertainty of how forests will grow and react to climate change. One possible tool to balance these drivers and the uncertainty of climate change is an adaptive management framework...
Resource Type:: Capstone Project

A Statistical Analysis and Interpretation of the HyperLogLog Algorithm

Creator:: Chick, Alexander
Abstract:: The HyperLogLog (HLL) algorithm is used to estimate the cardinality of large sets. This thesis gives a novel analysis of the HyperLogLog algorithm by using techniques from statistics and probability. Initially, closed form bounds for the mean and variance of the max of n independent and identically distributed geometric random...

Using Point Clouds for Single Tree Forest Inventory at the Beginning and End of the Rotation

Creator:: Garms, Cory G.
Abstract:: The portability and reduced price of unmanned aerial systems (UAS) in recent years has led to a broad range of new UAS-enabled scientific inquiries, including for forestry. Small, consumer-grade UAS are advantageous for forest measurements due to their portability, ease and safety of deployment, and notably, they are currently the...

Measuring and Modeling the Structure of Coniferous Trees with Point Clouds Data

Creator:: Fang, Rong
Abstract:: Coniferous trees are a major North American crop that has been intensively managed for its commercial value, while also serving as critical habitat for abundant wildlife and as carbon sinks. Having diverse functions, North American temperate coniferous forests have become a research hotspot for numerous scientific studies aiming to integrate...

LiDAR as Tool for Assessing Hazard Fuel Reduction Projects

Creator:: Olszewski, Julia H.
Abstract:: Land management practices in much of the western US that included wildland fire suppression have led to greater fuel loads than has been typical of historical fire regimes. In response to the increased wildland fire risk, “restoration” has emerged as a forest management goal. Restoration involves removal of uncharacteristic amounts...

Canopy Ecology of Swiss Needle Cast in Young and Mature/Old-growth Douglas-fir (Pseudotsuga menziesii)

Creator:: Lan, Yung-Hsiang
Abstract:: Swiss needle cast (SNC) is a foliage disease of Douglas-fir caused by Nothophaeocryptopus gaeumannii, an Ascomycete fungus (Mycosphaerellaceae) that causes growth reductions in Douglas-fir plantations across the Pacific Northwest. Epidemiology of the fungus is generally well known in plantation trees, but the relationship between disease expression and foliage nutrition and...

Environmental Remote Sensing with Unmanned Aircraft Systems

Creator:: Burnett, Jonathan D.
Abstract:: Small Unmanned Aircraft Systems (sUASs) equipped with optical sensors are capableof remotely sensing landscapes and wildlife at spatial and temporal resolutions that werepreviously inaccessible due to technical and budgetary limitations. Conventional remotesensing and photogrammetric workflows can be applied to the resulting high resolution imageryto facilitate new types of scientific inquiry....

Analysis and operational considerations of biomass extraction on steep terrain in western Oregon

Creator:: Flint, Benjamin R.
Abstract:: The development of bioenergy from biomass has dominated the minds of forest engineering researchers over the last decade. One of the main themes that has been generated from that research is that bioenergy from biomass has major operational hurdles to overcome before becoming economically feasible. More directly, the impact of...

A new approach to pricing real options on swaps : a new solution technique and extension to the non-a.s. finite stopping realm

Creator:: Chu, Uran
Abstract:: This thesis consists of extensions of results on a perpetual American swaption problem. Companies routinely plan to swap uncertain benefits with uncertain costs in the future for their own benefits. Our work explores the choice of timing policies associated with the swap in the form of an optimal stopping problem....
