The Economic Impacts Of Forest Pathogens In Washington State: A Hedonic Approach, Logan Blair
The Economic Impacts Of Forest Pathogens In Washington State: A Hedonic Approach, Logan Blair
All Master's Theses
An increase in the incidence of forest pathogens in the Western US has created new resource management issues. In this research I employ a dataset of 170,141 housing transactions in twelve Western Washington counties to quantify the impacts of parasitic forest damage on the proxy real estate market. Specifically, I estimate a set of hedonic fixed effects models to control for omitted variable bias and spatial autocorrelation. Results show statistically significant impacts on property values in the presence of species specific and aggregate defoliation, suggesting new information for forestry management and policy.
Influence Of Landscape On Gene Differentiation In The American Pika (Ochotona Princeps) Within The Interstate 90 Snoqualmie Pass Corridor, Craig P. Fergus
Influence Of Landscape On Gene Differentiation In The American Pika (Ochotona Princeps) Within The Interstate 90 Snoqualmie Pass Corridor, Craig P. Fergus
All Master's Theses
Understanding the impact of different landscape features on the movement of genes among populations can be helpful in managing wildlife populations. Our study used GIS tools to compare genetic connectivity among 13 American pika (Ochotona princeps) habitat patches across an approximately 77 square km area adjacent to Interstate 90 near Snoqualmie Pass, WA. Tissue samples were collected from 85 individuals and genotyped at six microsatellite loci to determine genetic differentiation among each pair of patches. A variety of models estimating the influence of landscape factors on gene flow were then used to find “resistance scores” between each pair …
