Vegetation Change from the Euro-American Settlement Era to the Present in Relation to Environment and Disturbance in Southwest Oregon

Creator:: Duren, Olivia C., Muir, Patricia S., and Hosten, Paul E.
Abstract:: Faced with landscapes degraded by fire suppression, logging, and grazing, land managers in the interior western US are attempting to restore habitat structure and function. In southwest Oregon, landscape-scale fuels treatments are being implemented with goals including recreating historic vegetation structure, despite poor understanding of the nature of the landscape...

Phytophthora species and riparian alder tree damage in western Oregon

Creator:: Sims, Laura L.
Abstract:: The genus Phytophthora contains some of the most destructive pathogens of forest trees, including the most destructive pathogen of alder in recent times, Phytophthora alni. Alder trees were reported to be suffering from canopy dieback in riparian ecosystems in western Oregon, which prompted a survey of alder health and monitoring...

A systematic and ecological study of Astragalus diaphanus (Fabaceae)

Creator:: Wright, Carolyn E.
Abstract:: Astragalus diaphanus is a rare plant endemic to the John Day River drainage of north-central Oregon. This species has several interesting features, including the dimorphism of its fruit and its geographical isolation from the two nearest taxonomically related species, which occur in Colorado. This study addressed the species' distribution and...

A systematic study of Lathyrus vestitus Nutt. ex T. & G. (Fabaceae) and allied species of the Pacific Coast

Creator:: Broich, Steven L.
Abstract:: Eight species of Lathvrus (Fabaceae, Faboideae) endemic to the Pacific Coast of North America were the subject of a systematic investigation.

Castilleja and Pedicularis are confirmed as telial hosts for white pine blister rust in whitebark pine ecosystems of Oregon and Washington

Creator:: Mulvey, Robin L.
Abstract:: The primary objective of this research was to determine if native species within the genera Castilleja and Pedicularis are naturally infected by white pine blister rust (Cronartium ribicola) in whitebark pine ecosystems of the Oregon and Washington Cascade Range. Secondary objectives were to monitor the phenology of aecial and telial...

Port-Orford-cedar and Phytophthora lateralis : grafting and heritability of resistance in the host, and variation in the pathogen

Creator:: McWilliams, Michael G.
Abstract:: Port-Orford-cedar (Chamaecyparis lawsoniana) is a forest tree native to a small area of Oregon and California. A root disease caused by Phytophthora lateralis causes widespread mortality of Port-Orford-cedar. This dissertation examines three important elements of the Port-Orford-cedar P. lateralis pathosystem related to breeding for disease resistance: use of resistant rootstocks...

Revegetation in the 1914-1915 devastated area of Lassen Volcanic National Park

Creator:: Bailey, Warren Hutchinson, 1914-
Abstract:: At the time of the eruptions of Lassen Peak in 1914-1915, an area of vegetation along the east slope of the mountain approximately 1 1/4 miles wide and four miles long was destroyed. Except for a few surviving trees, all vegetation was destroyed. A study of the revegetation of this...

Description of the plant communities and succession of the Oregon coast grasslands

Creator:: Ripley, James Douglas
Abstract:: In an effort to describe the plant communities and succession of the Oregon coastal grasslands, vegetation and environmental data were collected from 75 stands at 24 separate locations ranging from Cape Falcon in Tillamook County to Cape Ferrelo in Curry County. The vegetation data consisted of cover and frequency values...

A G-type Lectin Receptor-like Kinase Associated with Septoria Canker Resistance and Susceptibility Described using Multi-omics and Biotechnology

Creator:: Lenz, Ryan R.
Abstract:: Managers of forest and plantation ecosystems are encountering growing problems involving plant pathogens and the expanding geographic ranges of these pathogens. Historically unexposed stands are exceptionally vulnerable when a non-native pathogen is introduced because these pathogens can cause devastating disease in a host population that lacks co-evolved resistance mechanisms. One...
