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.

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.

Abstract: Forest management is a multi-objective problem. Decision support in forestry management can benefit from a comprehensive approach to develop strategies that meet all the constraints while also accounting for their effects on ecosystem services. My research provides practical methods for decision support in forest management that can enhance forest stewardship and facilitate planning and communicating proposed actions and their effects to the public.

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).
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
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.

Title: Relationships between fine root productivity and aboveground forest metrics
Committee: Chair Dr. Monika Moskal, Dr. Dylan Fischer (The Evergreen State College faculty), and Dr. Daniel Vogt
Currently, the pools and fluxes of belowground living plant C in most ecosystems is poorly understood (Clark et al. 2001). There is a pressing need for studies which address the variability of fine roots and to accurately describe the causes for variability of belowground plant C. This study will address variability in fine root productivity as it is influenced by overstory productivity, overstory diversity, and variation of canopy height. We use imagery from a minirhizotron optical scanning device for estimates of fine root productivity, while overstory productivity and overstory diversity were assessed with traditional field based methods. Aerial LiDAR was used for estimates of variation of canopy height, which provided an estimate of the standard deviation of upper canopy height. Estimates of fine root productivity were related to estimates of overstory productivity, overstory diversity and standard deviation of canopy height with the goal of finding the best predictor of variation in fine root production. We prioritize this research in terms of three hypotheses: 1) There is a relationship between overstory productivity and fine root productivity; 2) There is a relationship between overstory diversity and fine root productivity; 3) There are relationships between standard deviation of canopy height and fine root productivity. A better understanding of relationships between aboveground metrics and variability of belowground plant C could allow for an increased understanding of causes for variation of belowground plant C, as there is a pressing need to accurately estimate whole system C in forest ecosystems (Toan et al. 2004; Hese et al. 2004; Boudreau et al. 2008).

Above and below the canopy of bigleaf maple (Acer macrophyllum): canopy soils, litterfall and decomposition in an old-growth temperate rainforest
when: June 10th, 2013 10am
where: Forest Club room (And 207)
committee: Dr. Darlene Zabowski (chair), Dr. Nalini Nadkarni (co-chair), Dr. Bob Edmonds, Dr. Jerry Franklin, Dr. Marcia Ciol (gsr)
abstract: Epiphytes play critical functional roles in ecosystems by capturing rain, transforming nutrients and providing habitat for canopy dwelling organisms which are often habitat specialists. Few studies have examined the transfer of epiphytes from the canopy to the forest floor, or how decomposition differs between the canopy and forest floor environment in coastal temperate forest ecosystems.
In my study, I examined canopy soils, epiphytic litterfall and decomposition of materials associated with bigleaf maple (Acer macrophyllum) in an old-growth temperate forest at the Queets River watershed, Olympic National Park. An enhanced understanding of the movement of epiphytes can provide ecological insights into processes and dynamics of these complex forest ecosystems, and provide conservation strategies for managers.

What better way to end the academic year and start the graduation celebrations than with one last thesis defense?
Please join me as I defend my thesis, “Riparian Vegetation Structure and Composition in the Fire-Dependent Ecosystem of Eastern Washington”, at 11am on Thursday, June 13th in Bloedel 292.
Centered in the fire-dependent ecosystem of Eastern Washington, this study explores patterns of riparian vegetation structure and composition as well as the relative role of natural and anthropogenic processes. Interior Columbia Basin Ecosystem Management Project photo-interpreted resource aerial photos, Geographic Information Systems (GIS), and Permutational Multivariate Analysis of Variance (PERMANOVA) were used to compare riparian to upland areas, summarize the range of vegetation conditions present in the second half of the 20th century, and correlate vegetation with processes on the landscape. The spatial extent of the study was the Tapash Sustainable Forest Collaborative, offering multiple agencies the local best science needed for effective management. This field of work contributes not only to our understanding of a historically fire-dependent ecosystem, but also to the role of riparian areas within them.
