Creator:: Roach, Skylar K.
Abstract:: The effects of fire on above-ground forest systems have been extensively studied. However, research on fire effects on belowground processes is lacking. While the soil microbiome is understood to be vital to conifer growth and regeneration, the complexity of soils means that research on the topic has largely been accomplished...

Creator:: Boath, Max E.
Abstract:: Remote sensing techniques have been applied extensively in geospatial investigations, but their use in measuring soil physical attributes has been far less explored. Soil particle size distributions (PSD) are indispensable in modeling pedological and hydrological processes as well as biodiversity. However, estimation of PSD via gravimetric measurement methods, the standard...

Creator:: McCool, Katherine D.
Abstract:: Forest soils of the Pacific Northwest contain immense amounts of carbon (C). Increasing acreage burned by severe wildfire in the western Oregon Cascades threatens belowground carbon stocks and future site viability. This study investigates forest soil carbon changes after the 2020 Holiday Farm wildfire in a young, intensively managed Douglas-fir...

Creator:: Callan, Cannon F.
Abstract:: Forest Vegetation Management (VM) is an important tool used in the Pacific Northwest (PNW) for reforestation. It has been well documented that VM increases seedling survival and crop tree volume growth. What is less understood, is how altering the plant community and successional trajectory affects the way the ecosystem uses...

Creator:: Pokharel, Mandira
Abstract:: With mechanization, the logging industry has experienced a decreasing trend in the total number of workplace accidents, especially as new technology is making harvesting safer. However, there are areas within harvest units such as extremely steep slopes or rocky outcrops that are inaccessible to machines and are required to be...

Creator:: Frey, David W.
Abstract:: In intensively managed forest plantations in the northern Oregon Coast Range, herbicides are often applied during site preparation and early stand regeneration to reduce competition for resources for planted conifer seedlings. In addition to reducing competition for crop trees, herbicide applications may affect soil processes including decomposition and nutrient cycling,...

Creator:: Guevara, Claudio A.
Abstract:: Forest plantations in the Pacific Northwest are highly productive and have been intensively managed to maximize tree growth with practices such as Forest Vegetation Management (FVM). Different FVM regimes have been shown to enhance forest establishment by reducing the competition between the planted seedlings and early-seral vegetation. To better understand...

Creator:: Coons, Kristin L.
Abstract:: In this study an improved model of biomass and nutrient estimation of coastal Douglas-fir (Psuedotsuga menziesii) in the Pacific Northwest has been developed across a wide range of stand management regimes. This study quantifies and defines the type and intensity of biomass harvest and associated removal for actively managed stands...
