Lithologic Controls on Soil Carbon Partitioning in the Alaskan Coastal Temperate Rainforest

Creator:: Fleiner, Julia H.
Abstract:: Coastal Temperate Rainforests of western North America are carbon dense ecological regions of great importance due to their high biological productivity and climatic conditions leading to the natural accumulation of soil organic carbon (SOC). Yet, the distribution of SOC remains understudied in the CTR environments, particularly in upland mineral soils,...

Fuel Treatments of Ponderosa Pine (Pinus ponderosa) in the Blue Mountains of Eastern Oregon : A Mycorrhiza Perspective

Creator:: Hart, Benjamin T. N.
Abstract:: Over the course of the last century, a successful history of fire suppression has contributed to unsuccessful present day control over wildfire. In the absence of fire and the janitorial and ecological services it provides, drier inland forests are shifting in species composition and exceeding densities that cannot survive and...

Evidence of buried particulate organic carbon as foundation for heterotrophic carbon metabolism in the hyporheic zone of a montane headwater stream in the H. J. Andrews Experimental Forest, Oregon, USA

Creator:: Serchan, Satish P.
Abstract:: Streams and rivers play a critical role in global carbon (C) cycling by processing, storing, and transporting C. Headwater streams which make up more than 95% of the length of streams and rivers worldwide have disproportionate influence on fluvial C dynamics. The hyporheic zone (HZ) of headwater streams is a...

Recovery of High-graded Nothofagus Forests: Building Resilience Through Theory and Practice

Creator:: Soto, Daniel P.
Abstract:: The increasing human demands on natural resources, in combination with uncertainties about ecosystem dynamics due to global change, has led the scientific community to conclude that new approaches in understanding of ecological systems are needed to tackle environmental issues in an efficient manner. One development that has received more attention...

Post-fire Forest Management Activities Alter Soil Properties, Sediment Yields, and Vegetation Recovery in the Northern California Coast Range

Creator:: Cole, Ryan P.
Abstract:: The extent and severity of wildfires in forested regions are increasing throughout many regions on the planet, including western North America. High-severity wildfires directly affect soils and vegetation by altering soil hydraulic properties, reducing soil organic matter, exporting carbon and nitrogen, and killing trees and understory vegetation. These impacts can...

Response of Soil Microbial Activity and Community Composition to Timber Harvest in an Oregon Douglas-Fir Forest

Creator:: Martin, Kelsey M.
Abstract:: Forests and forest soils are some of the largest biologically active carbon reservoirs in the world. Therefore, understanding how disturbances, such as forest harvest, influence biogeochemical cycling is particularly important for managing forests sustainably. Timber harvest can have large impacts on forest soils, which may affect the long-term productivity and...

Soil Health and the Response of the Soil Microbial Community to Disturbances across Western North America

Creator:: Kersey, Jordan H.
Abstract:: Temperate coniferous forests, such as those that cover vast areas of the western US and Canada, have evolved to depend on cycles of disturbance for succession of species and overall ecosystem maintenance. Many of these forest systems are managed, often for timber production, where disturbances are of anthropogenic origin and...

Tires, Tracks, and Tethering: Idaho Steep Slope Harvesting

Creator:: Finster, Austin R.
Abstract:: Steep slope timber harvesting often falls under scrutiny of labor, safety, and operational challenges, but is beginning to advance past these barriers through substantial technological progression. Across previous decades, large advancements of technology have occurred in ground-based timber harvesting systems, giving mechanized options to every phase of timber harvesting. These...

Runoff and Sediment Transport from Harvested Hillslopes to Riparian Buffers of Rocky Mountain Headwater Catchment

Creator:: Puntenney-Desmond, Kira C.
Abstract:: Shallow subsurface flow and surface runoff are spatially and temporally variable in forested environments. The location and timing of this runoff depends on both site characteristics (e.g., vegetation, soil texture, geology, and topography) and on time-varying conditions (e.g., soil water content, precipitation type, duration, magnitude, and intensity). Forest management activities...

Long-term Effects of Vegetation Management on Plant and Soil Derived Nutrient Budgets for Plantations of Four Western Conifer Species

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...
