Title: Seasonal and Diurnal Patterns of Whole-Tree Plant Water Relations in Three Pacific Northwest Conifer Species: Thuja plicata, Pseudotsuga menziesii, and Tsuga heterophylla

Committee: Greg Ettl (chair), Tom Hinckey, Soo-Hyung Kim

Abstract: This study examines the diurnal and seasonal water relations of mature western redcedar, Douglas-fir, and western hemlock using continuous sap flow and stem increment monitoring at a study site in western Washington. By carefully selecting a small site containing both large dominant and smaller trees of each of the tree study species, we were able to test some common assumptions regarding species’ ecological tolerances. Specific objectives of the study were to illustrate seasonal and diurnal sap flow and water storage patterns, to examine the relative effects of canopy position and tree species on sap flow rates, to estimate growing season length, and to approximate whole-stand transpiration. This study produced semi-continuous sap flow and dendrometer band data for two and a half years, encompassing three growing seasons.

Patrick Bridegam Thesis Defense: March 6, 10am AND 207

Please join Patrick Bridegam for his defense of his master’s thesis: "The Effects of Consumer Country Policies to Address Trade in Suspicious Wood Products: The Effects of the 2008 Lacey Act Amendments on International Trade in Forest Products"

Thursday, March 6

10:00 am

Anderson 207 (Forest Club Room)

Committee: Ivan Eastin (Committee Chair; SEFS and CINTRAFOR), Mark Long (Evans School of Public Affairs), and Bruce Bare (SEFS)

Abstract: Despite international efforts, illegal logging and its associated social, ecological, and economic effects continue on a scale that is of global concern, with significant amounts of illegally-harvested wood and the resulting wood products entering into international trade flows. Recently, major importers of forest products have begun to implement legislation prohibiting the possession and/or importation of wood and wood products that are of illegal origin, such as the U.S. Lacey Act Amendments of 2008. To date, no studies have systematically investigated the effects of the 2008 Lacey Act Amendments on the international trade in forest products. Drawing on bilateral trade data and using a quantitative, regression-based comparative case study methodology, I evaluated the effects of the 2008 Lacey Act Amendments on the international trade in forest products. A data-driven method was used to create an aggregate control group for comparison with countries affected by the policy. If the policy has been effective in reducing the amount of forest products of illegal origin being imported into the U.S., we would expect to see some unique differences in post-policy U.S. imports of wood and wood products from areas with high levels of suspicious wood in their supplies. Results from preliminary analyses show no significant differences in post-policy U.S. imports of wood products of suspicious origins. However, the policy may be affecting the suspicious imports of major exporters of finished products to the U.S.

Jordan Crawford MS defense, Th Dec 5, 1pm BLB 292

My thesis defense will be December 5th, at 1pm in BLD 292. It’s titled "Techno-economic analysis of hydrocarbon biofuels from poplar biomass via acetic acid fermentation."

Committee: Rick Gustafson (chair) Renata Bura, Fernando Resende, Sergey Rabotyagov

Infrastructure compatible hydrocarbon biofuel that is proposed to qualify as renewable transportation fuel under the U.S. Energy Independence and Security Act of 2007 (EISA) and Renewable Fuel Standard (RFS2) is evaluated. The process uses hybrid poplar for feedstock, which undergoes dilute acid pretreatment and enzymatic hydrolysis. Sugars are fermented to acetic acid, which undergoes conversion to ethyl acetate, ethanol, ethylene, and finally a saturated hydrocarbon end product with yields of 80 gallons of jet fuel per bone dry ton feed. A lignin rich stream that is not fermented may either be burned for steam and electricity production, or gasified. During the biofuel production process, hydrogen gas is required in two unit operations and may be obtained by various methods including lignin gasification. Both technical and economic aspects of the biorefinery are analyzed, with a range of hydrogen sources considered. These include steam reforming of natural gas, gasification of lignin, and electrolysis of water using seasonal excess hydroelectric capacity in the U.S. Pacific Northwest. Cash operating costs are estimated to range from 2.55 to 3.38 USD per gallon jet fuel depending on facility capacity. Capacities of 25 to 150 million gallons of polymer jet fuel per year are investigated, with capital investments in the range of 304 to 1,150 million USD. The production of alternative, intermediate products to jet fuel is briefly explored.

Jacob Lipson Thesis Defense Fri Nov 15th, AND 22, 12:30pm

Snacks!! (and Thesis Defense too).

Please join Jacob Lipson for his MS (SEFS) and MPA (Evans School) thesis defense “Business Activities, Decision-Making, and Barriers to Viability of the Forest Biomass Harvesting Industry in Washington State” on Friday, November 15, at 12:30pm in Anderson 22.

Using forest biomass- the leftover byproducts of timber harvesting- as an energy source potentially presents a win-win alignment of environmental goals, economic growth, and business successes. This research explores the thoughts and actions of businesses actively involved in the harvest, collection, processing, and transportation of forest biomass to energy production facilities. Drawing on interviews with 21 firms in the industry, this research characterizes the industrial organization, activities, and decision-making of forest biomass harvesting businesses. This new understanding of forest biomass businesses is then used to examine economic and policy barriers to the more widespread use of forest biomass for energy production.

Jacob’s committee chair is Professor Clare Ryan, and other committee members are Sergey Rabotyagov (SEFS) and David Layton (Evans).

John Simeone MS Defense Thurs. Aug. 22 at 9am in Anderson 22

My MS defense will be this Thursday, August 22nd at 9am in Anderson Hall room 22.

I will presenting on implications for the development of a sustainable forest sector in the Russian Far East.

Here’s my abstract:

Twenty-three percent of global forests are contained within the Russian Federation’s nine time zones, which is more than the combined forest area of Canada and Brazil. Despite the fact that Russia contains the largest area of natural forests in the world, its current share in the trade of world forest products is below 4 percent. Russia’s forest sector is known for high transportation costs, aging infrastructure, and high instances of bribery and corruption, issues that have had widespread impacts. In 2006, Russia’s easternmost region, the Far East, had the ability to process only two percent of its regional harvest. While the Far East’s processing capacity was particularly low, the situation for most other regions of Russia was little better. With such a low capacity to process timber, Russia increasingly became an exporter of roundwood. Beginning in 2007, the Russian government implemented a series of policies, including export tariffs on roundwood, in order to develop a more competitive timber-processing sector and increase the production and exports of value-added forest products. In 2009, 96% of the forest product exports from the Far East were in the form of unprocessed roundwood logs. Thus, the efficacy of these national forest policies in the Far East has been unclear in the short-term. Additionally, Russia’s World Trade Organization (WTO) accession in August 2012 is expected to alter many aspects of Russia’s forest sector development and exports. Through semi-structured interviews with locals involved in the forest sector in the Russian Far East, this research investigates the most recent challenges facing the development of a sustainable forestry in two southern provinces in Russia’s Far East, Primorskiy Krai and Khabarovskiy Krai. There may be no other two provinces in Russia where political will, economic value, the shadow economy and international interests for timber all intersect and are so keenly observed.

Dissertation: Understanding climate and very large wildfires in the Western United States at scales for modeling air quality

Abstract

Wildfires, especially the largest ones, can have lasting ecological and social effects both directly on the landscape and indirectly on the atmosphere and climate; thus making them a part of a much more complicated system. Both climate and fire regimes are expected to change into the future while air quality, the composition of the near surface atmosphere, continues to be regulated. It is necessary to understand how climate, wildfire, and air quality interact to mitigate air quality. There are limited studies, however, at spatial and temporal scales appropriate to integrate climate, wildfire, and air quality data. To begin to study the interactions among these three components, evidence from very large wildfires, here defined as megafires, provides a useful starting place. Megafires contribute to significant degradation in air quality and consequently climate. In this dissertation, I demonstrated, using a systematic approach, that broad spatial and fine temporal resolutions are the best scales by which to understand how climate, wildfire, and air quality interact. Thus, using broad wildfire data aggregated to the spatial scale of eight US National Interagency Fire Center Geographic Area Coordination Centers (GACCs) across the western contiguous US, and daily and monthly climate data, I developed logistic regression models to predict the probability that a megafire will occur in a given week. Significant climate predictors of megafires vary by GACC and are similar to those found by other studies for aggregate annual area burned. Thus megafires may influence the analysis of aggregate statistics substantially. For all eight GACCs, projecting these models showed a significant (p≤0.05) difference between the historical period from 1979 to 2010 and both Intergovernmental Panel on Climate Change future scenarios, representative concentration pathways (RCPs) 4.5 and 8.5, during 2031 to 2060. Generally, with the exception of the Southwest and Northern California, megafires will be more likely both throughout the fire season and from year to year, with more pronounced patterns under RCP 8.5 than RCP 4.5. This research provides a political and managerial motivation to analyze the effects of a changing climate on air quality degradation from megafires.
