Overstory composition and stand structure shifts within inter-mixed ponderosa pine and lodgepole pine stands of the south-central Oregon pumice zone

Creator:: Shuffield, Chaylon D.
Abstract:: Ponderosa pine (Pinus ponderosa) and lodgepole pine (Pinus contorta var. murrayana) forests of south-central Oregon have been extensively researched over the last century. However, little information has been reported on overstory composition and stand structure shifts associated with fire exclusion within inter-mixed ponderosa pine and lodgepole pine stands of the...

Conifer regeneration, understory vegetation and artificially topped conifer responses to alternative silvicultural treatments

Creator:: Huff, Tristan
Abstract:: Historically, between 40-60% of the Coast Range of Oregon was comprised of structurally diverse, old forests initiated by disturbances of various spatial scales ranging from thousands of acres (large fires) to the size of a single tree (windthrow). The predominant regeneration method of the past several decades, however, has been...

Red Tree Voles: Examining the Potential Factors Limiting Occupancy and Survival in Young Conifer Forests of the Central Oregon Coast Range

Creator:: Durham, William P.
Abstract:: Forested landscapes in the Pacific Northwest have changed drastically in the last Century with large-scale wildfires, and increased extent and frequency of commercial timber harvests. Thus, landscapes once dominated by older forest cover types became a matrix of younger forests with patches of older forests dispersed throughout. These younger forests...

Sustainable biomass supply from fuel reduction treatments : a biomass assessment of federally owned land in eastern Oregon

Creator:: Vogler, Kevin C.
Abstract:: Wildfire exclusion over the past century or more has resulted in extensive fuel accumulations throughout much of the West that combined with recent climatic patterns have increased the frequency of relatively uncommon, large, high-severity wildfires. Forest restoration treatments intended to alter landscape-level fire disturbance patterns can be difficult to implement...

Treatment options for controlling Brachypodium sylvaticum and impacts on native vegetation

Creator:: Fjeran, Taylor K.
Abstract:: Invasive vegetation control studies traditionally aim to control existing populations as well as limit future spread of the species. However, little additional attention has been dedicated to aiding native communities to recover and reestablish. One prominent example of a studied invasive is Brachypodium sylvaticum (Huds.) P. Beauv. (false brome), a...

Influence of silvicultural treatments, overstory, and understory vegetation on quaking aspen (Populus tremuloides) regeneration in southeastern Idaho

Creator:: Muñoz, Bethany L.
Abstract:: Quaking aspen (Populus tremuloides Michx.) is known to be a widely distributed, shade-intolerant and short-lived hardwood found in both seral, even-aged and stable, uneven aged stands. There have been reports of extensive aspen mortality, crown thinning, and branch dieback across North America that have been linked to the occurrence of...

Red tree voles in fragmented forests

Creator:: Piasecki, Jason T.
Abstract:: The red tree vole (Arborimus longicaudus) is an arboreal Arvicoline rodent endemic to conifer dominated forests of western Oregon and northwestern California. While commonly associated with old forests, often inhabiting stands over 80 years old, tree voles have also been found in young forests between 20 and 80 years old....

Restoring Ponderosa Pine: Understanding Individual Tree Defenses, Disturbance Responses, and Resilience

Creator:: Johnson, Christal
Abstract:: The aim of this research was to provide forest managers and researchers with a better understanding of individual tree defenses and tree responses to disturbances, within a Collaborative Forest Landscape Restoration Program area. Forest restoration often aims to increase stand-level resistance to uncharacteristic changes, and stand-level resistance begins with tree-level...

Mixed-Severity Fire Effects on Biological Legacies and Vegetation Response in Pseudotsuga Forests of Western Oregon's Central Cascades, USA

Creator:: Dunn, Christopher J.
Abstract:: 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...

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...
