Daugherty Water for Food Global Institute: Faculty Publications

This study aims to assess the link between fluoride content in groundwater and its impact on dental health in rural communities of the Ethiopian Rift. A total of 148 water samples were collected from two drainage basins within the Main Ethiopian Rift (MER). In the Ziway-Shala basin in particular, wells had high fluoride levels (mean: 9.4 ± 10.5 mg/L; range: 1.1 to 68 mg/L), with 48 of 50 exceeding the WHO drinking water guideline limit of 1.5 mg/L. Total average daily intake of fluoride from drinking groundwater (calculated per weight unit) was also found to be six times higher than …

As Unidades De Conservação E A Floresta Ombrófila Mista No Estado Do Paraná, Paulo Dt Dl Pires, Douglas Magnus Zeni Jr, Debora Gaulke

Daugherty Water for Food Global Institute: Faculty Publications

O intenso processo de ocupação territorial, uso desordenado dos recursos naturais e destruição de áreas verdes iniciadas no século XIX, são os principais motivos da intensa devastação das Florestas com Araucárias. Como meio de efetivação da proteção e desenvolvimento florestal, o Brasil adotou em sua política ambiental a criação do Sistema de Unidades de Conservação nas categorias, de proteção integral e uso sustentável. Uma alternativa viável é a regulação dos estoques de madeira no Estado por meio de Unidade de Conservação de Uso Sustentável. O que se pretende a partir deste ponto é analisar a possibilidade da criação de regulamentação …

Producing Edible Landscapes In Seattle's Urban Forest, Rebecca J. Mclain, Melissa R. Poe, Patrick T. Hurley, Joyce Lecompte, Marla R. Emery

Environment and Sustainability Faculty Publications

Over the next decades, green infrastructure initiatives such as tree planting campaigns, and ecological restoration will dramatically change the species composition, species distribution and structure of urban forests across the United States. These impending changes are accompanied by a demand for urban public spaces where people can engage in practices such as gleaning, gardening, and livestock production. This article analyzes the institutional framework that undergirds efforts in Seattle, Washington to normalize the production and use of edible landscapes. We focus attention on the role of grassroots fruit gleaning groups and highlight their bridging function between Seattle's agriculture and forestry policy …

Interannual And Spatial Impacts Of Phenological Transitions, Growing Season Length, And Spring And Autumn Temperatures On Carbon Sequestration: A North America Flux Data Synthesis, Chaoyang Wu, Alemu Gonsamo, Jing Ming Chen, Werner A. Kurz, David T. Price, Peter M. Lafleur, Rachhpal S. Jassal, Danilo Dragoni, Gil Bohrer, Christopher M. Gough, Shashi B. Verma, Andrew E. Suyker, J. William Munger

School of Natural Resources: Faculty Publications

Understanding feedbacks of ecosystem carbon sequestration to climate change is an urgent step in developing future ecosystem models. Using 187 site-years of flux data observed at 24 sites covering three plant functional types (i.e. evergreen forests (EF), deciduous forests (DF) and non-forest ecosystems (NF) (e.g., crop, grassland, wetland)) in North America, we present an analysis of both interannual and spatial relationships between annual net ecosystem production (NEP) and phenological indicators, including the flux-based carbon uptake period (CUP) and its transitions, degree-day-derived growing season length (GSL), and spring and autumn temperatures. Diverse responses were acquired between annul NEP and these indicators …

A Synoptic Perspective Of The Record 1-2 May 2010 Mid-South Heavy Precipitation Event, Joshua D. Durkee, Lee Campbell, Kyle Berry, Dustin Jordan, Gregory Goodrich, Rezaul Mahmood, Stuart Foster

High Plains Regional Climate Center: Staff Publications

During 1–2 May 2010, a series of strong thunderstorms led to 41, 57, and 43 tornado, severe wind, and severe hail reports, respectively, across portions of the southern United States. In addition to severe weather, these storms also distributed recordsetting rainfall amounts across the mid-South region, which contributed to historic flooding across portions of central and western Kentucky and Tennessee (Fig. 1). This heavy precipitation event was sampled by multiple surface observational networks, including (but not limited to) 48 research-grade automated stations from the Kentucky Mesonet (www.kymesonet .org), first-order automated stations from the National Weather Service (NWS; www.ncdc.noaa.gov /oa/ncdc.html), and …

Fire And The Invasive Annual Grass Microstegium Vimineum In Eastern Deciduous Forests, S. Luke Flory, Keith Clay, Sarah Emery, Joseph Robb

Joint Fire Science Program Research Project Reports

Non-native plant invasions have the potential to change natural and prescribed fire regimes by increasing fuel loads, continuity of fuels, and fuel composition, which may alter fire intensity, damage native species, and promote further invasions. In this project we sought to evaluate the interaction between fire and the invasive annual grass Microstegium vimineum in eastern deciduous forests. Our goal was to determine if invasions enhance fire intensity, including fire temperatures, flame heights, and fire duration, and negatively affect tree regeneration, and stimulate further invasions. We also sought to determine how prescribed fires and the timing of fires affect the density …

Wildland Fire Suppression And Land Development In The Wildland/Urban Interface, Sheila Olmstead, Carolyn Kousky, Roger Sedjo

Joint Fire Science Program Research Project Reports

This project has explored the hypothesis that public fire suppression in fire‐prone areas acts as a subsidy to landowners, incentivizing conversion of land to residential and commercial development. Landowners do not bear the full cost of their choice to build on land in fire‐prone areas, since they do not pay for suppression, though they reap all of the benefits, potentially resulting in economically inefficient levels of development. To test this hypothesis, we performed an econometric analysis of U.S. land use change between 1970 and 2000. Statistically, we identified the impacts of changes in fire suppression policy by exploiting a natural …

To Burn Or Not To Burn Oriental Bittersweet: A Fire Manager’S Conundrum, Noel B. Pavlovic, Stacey A. Leicht-Young, Ralph Grundel, Scott A. Weyenberg, Neal Mulconrey

Joint Fire Science Program Research Project Reports

Oriental bittersweet (Celastrus orbiculatus) is an introduced liana (woody vine) that has invaded much of the Eastern United States and is expanding west into the Great Plains. In forests, it can girdle and damage canopy trees. At Indiana Dunes, we have discovered that it is invading non-forested dune habitats as well. Anecdotal evidence suggests that fire might facilitate its spread, but the relationship between fire and this aggressive invader is poorly understood. We investigated four areas important to fire management of oriental bittersweet, each of which we will briefly summarize here. 1) What fire temperatures cause seed mortality? For seeds, …

Using Escaped Prescribed Fire Reviews To Improve Organizational Learning, Anne E. Black Dr., James Saveland Dr., Dave Thomas, Jennifer Ziegler Dr.

Joint Fire Science Program Research Project Reports

The US wildland fire community has been interested in cultivating organizational learning to improve safety and overall performance for a number of years. A key focus has been on understanding the difference between culpability (to be guilty) and accountability (to explain) and on re-orienting review processes towards building a collective account of (as opposed to finding individual blame for) unwanted outcomes. A variety of innovative methodologies have been developed, yet until this project, there has been no systematic reflection to determine whether or how any of the existing review processes might be assisting organizational learning. Through a series of five …

A Decision-Support System For Assessing The Impact Of Fire Management On Threatened And Endangered Species, Gordon Reeves, Rebecca Flitcroft, Lee E. Benda, Pete Bisson, Steve Wondzell, Jeff Falke, Kris Mcnyset, Ken Vance-Borland, Dan Miller

Joint Fire Science Program Research Project Reports

Historically, wildfire was an important agent of change in landscapes across the western United States. Fires of varying magnitudes and extents contributed to a mosaic of dynamic landscape conditions. For the past century, fire management that focuses on fire suppression has effectively altered the composition of many vegetation communities across the landscape. Fire management and other landuse practices associated with natural resource use, agriculture, and residential development have changed the complexity of terrestrial landscapes. Aquatic systems have not been exempt from these changes: alterations in disturbance processes on the landscape have changed inputs into the stream environment, and practices such …

Using first a binary variable indicating the presence or absence of a wildfire prevention program on lands managed by the tribe or …

Affecting Risk: Improving Hazard Communication In The Wildland-Urban Interface, Melissa Wright Dr., Destiny Aman

Joint Fire Science Program Research Project Reports

Wildfire hazard is a growing problem in many areas of the United States, especially in the wildland-urban interface (WUI), where homes and other structures border or intermingle with forests, shrubs and grasslands. Despite years of educational outreach by fire management officials promoting effective and affordable mitigation strategies, research shows that residents, especially seasonal residents and those new to an area, still tend to under-invest in mitigation, even when they perceive their risk to be high. Meanwhile, the social and economic costs of wildfire have increased with fire size and intensity and far exceed the costs of mitigation. This problem has …

Age-Class Mosaics And Wind-Driven Fire: Further Fuel For The Debate, Jan L. Beyers, Philip J. Riggan, David Weise, Timothy Paysen, Marcia Narog

Joint Fire Science Program Research Project Reports

In 2006 the Santa Ana wind-driven Esperanza fire burned through the North Mountain Experimental Area (NMEA) and vicinity, including the scars of 10 previous fires. Multiple images of the fire’s progression were taken using PSW Research Station’s airborne FireMapper thermal-imaging system. Existing fuels data and historic NMEA maps plus new fire images were used to investigate relationships between vegetation history, fire behavior and severity, and fuel consumption. Soil samples were collected at a subset of fire severity sample points to assess seed bank survival. Coordinated documentation of vegetation recovery addressed the effects of age class and fire severity on chaparral …

Assessing Fuels Treatments In Southern California National Forests In The Context Of Climate Change, Timothy J. Brown, Crystal A. Kolden, John T. Abatzoglou

Joint Fire Science Program Research Project Reports

One of the key uncertainties in fuels treatments is their longevity under a changing climate. Several recent studies have assessed fuel treatment effectiveness during historic fires, and in many cases found the treatment less effective than desired, particularly during extreme or record conditions. In 2007, southern California experienced one of the most severe fire seasons to-date due to record low fuel moistures early in the fire season (a key driver of the two-month long Zaca fire) and historic Santa Ana winds late in the season (resulting in several large late October fires). Climate change projections for the region suggest that …

Can Climate Change Increase Fire Severity Independent Of Fire Intensity?, Phil Van Mantgem, Marybeth Keifer, Rob Klinger, Eric Knapp

Joint Fire Science Program Research Project Reports

We tested the idea that climate may affect forest fire severity independent of fire intensity. Pervasive warming can lead to chronic stress on forest trees (McDowell et al. 2008; Raffa et al. 2008), resulting in higher sensitivity to fire-induced damage (van Mantgem et al. 2003). Thus, there may be ongoing increases in fire severity (the number of trees killed), even when there is no change in fire intensity (the amount of heat released during a fire). We examined this question at a subcontinental scale by synthesizing existing information from plot-based prescribed fire monitoring databases across the western United States of …

Phase 1 Of The Smoke And Emissions Model Intercomparison Project (Semip): Creation Of Semip And Evaluation Of Current Models, Narasimhan K. Larkin, Tara M. Strand, Stacy A. Drury, Sean M. Raffuse, Robert C. Solomon, Susan M. O'Neill, Neill Wheeler, Shihming Huang, Miriam Roring, Hilary R. Hafner

Joint Fire Science Program Research Project Reports

Managers, regulators, and others often need information on the emissions from wildland fire and their expected smoke impacts. In order to create this information, combinations of models are utilized. The modeling steps follow a logical progression from fire activity through to emissions and dispersion. In general, several models and/or datasets are available for each modeling step, resulting in a large number of combinations that can be created to produce fire emissions or smoke impacts. Researchers, managers, and policy makers need information on how different model choices affect the resulting output, and guidance on what choices to make in selecting the …

A National Study Of The Consequences Of Fire And Fire Surrogate Treatments, Phil Weatherspoon, Jim Agee, Phil Aune, Jim Baldwin, Jamie Barbour, Frank Beall, Julio Betancourt, Ralph Boerner, Matt Busse, Carl Edminster, Gary Fiddler, Carl Fiedler, Sally Haase, Kathy Harchsen, Mick Harrington, Ron Hodgson, Sue Husari, Jon Keeley, Mike Landram, Bill Laudenslayer, Jim Mciver, Dan Neary, Bill Otrosina, Roger Ottmar, Martin Ritchie, Kevin Ryan, Patrick Shea, Carl Skinner, Scott Stephens, Nate Stephensen, Elaine Kennedy Sutherland, Bob Vihanek, Dale Wade, Tom Waldrop, Dan Yaussy, Andy Youngblood, Steve Zack

Joint Fire Science Program Research Project Reports

Many U.S. forests, especially those with historically short-interval, low- to moderate-severity fire regimes, are too dense and have excessive quantities of fuels. Widespread treatments are needed to restore ecological integrity and reduce the high risk of destructive, uncharacteristically severe fires in these forests. Among possible treatments, however, the appropriate balance among cuttings, mechanical fuel treatments, and prescribed fire is often unclear. For improved decisionmaking, resource managers need much better information about the consequences of alternative management practices involving fire and mechanicaVmanual "fire surrogates." Long-term, interdisciplinary research thus should be initiated to quantify the consequences and tradeoffs of alternative fire and …

Cumulative Effects Of Fire And Fuels Management On Stream Water Quality And Ecosystem Dynamics, David S. Pilloid, Robert S. Arkle

Joint Fire Science Program Research Project Reports

Prescribed fires and wildland fire-use are increasingly important management tools used to reduce fuel loads and restore the ecological integrity of western forests. Although a basic understanding of the effects of fire on aquatic ecosystems exists, the cumulative and possibly synergistic effects of wildfire following prescribed fire are unknown. Wildfires following prescribed fire may produce different burn severities and effects on riparian and stream ecosystems than wildfires in fire suppressed forests (e.g., fires absent >70 yrs) or prescribed fires alone. The goal of this study was to quantify and compare the effects of wildfire on stream and riparian ecosystems under …

Effects Of Fires And Insects On Fuel Structures In Piñon-Juniper And Post-Fire Invasive Communities, Lisa Floyd-Hanna Dr., Tim Crews Dr., William H. Romme, David Hanna, Monique Rocca Dr., Dustin Hanna, George San Miguel

Joint Fire Science Program Research Project Reports

In the last decade, piñon-juniper (Pinus edulis-Juniperus osteosperma) woodlands of southwestern Colorado have been heavily impacted by wildfires and insects, and the effects on fuel structures and future fire intervals have been unclear. In these piñon-juniper woodlands, pre-historic fire rotations of up to 400 years were documented, but in recent climatic conditions, large stand-replacing wildfires burned between 1989 and 2008. Since the 1990s, a period of drought and rising temperatures, portions of the post-fire landscape were targets for invasive Carduus nutans, muskthistle and Bromus tectorum, cheatgrass, whose presence create unprecedented fuels, may shorten fire intervals, and reduce native biodiversity. We …

Engaging The Humanities To Address Wildland Fire Issues, Fred Swanson, Nathaniel Brodie, Charles Goodrich

Joint Fire Science Program Research Project Reports

This project examined existing programs and potential options for collaborations among the humanities, art, science, land management, and public concerning wildfire and wildfire policy and education. These programs and partnerships include creative residencies; conferences, workshops, and symposia; art-science collaborative field studies; and community programs and partnerships. We also reviewed how popular literature frames, reflects and has affected our cultural understanding of wildfire. Our analysis concludes that, compared to the richness of the subject of wildfire, compared to the way wildfire encapsulates all the complexities and controversies of culture, history, and ecology, wildfire’s potential as a literary subject remains largely unfulfilled. …

Estimating Critical Climate-Driven Thresholds In Landscape Dynamics Using Spatial Simulation Modeling: Climate Change Tipping Points In Fire Management, Robert E. Keane, Rachel A. Loehman

Joint Fire Science Program Research Project Reports

Climate projections for the next 20-50 years forecast higher temperatures and variable precipitation for many landscapes in the western United States. Climate changes may cause or contribute to threshold shifts, or tipping points, where relatively small shifts in climate result in large, abrupt, and persistent changes in landscape patterns and fire regimes. Rather than simulate potential climate-fire interactions using future climate data derived from Global Climate Models (GCMs), we developed sets of progressively warmer and drier or wetter climate scenarios that span and exceed the range of GCM outputs for the western US, including temperature and precipitation combinations that may …

Evaluating The Effectiveness Of Wood Shreds On Post-Fire Erosion, Peter R. Robichaud, Randy B. Foltz, Charles G. Showers, James S. Groenier, Rory Sternke, Louise E. Ashmun, Robert E. Brown, Peter Jordan

Joint Fire Science Program Research Project Reports

Agricultural straw mulching is a commonly used post-fire hillslope erosion control treatment that is aerially applied by helicopter. While widely used and reasonably effective at reducing erosion, agricultural straw is not native to the forest environment. There is a growing consensus among Burned Area Emergency Response (BAER) teams that mulch made from native forest material would be preferable to agricultural straw. Wood shred mulch made from post-fire road hazard trees is an alternative to agricultural straw. An optimized blend of sizes of wood shreds was effective in reducing sediment yields in both indoor rainfall simulation and outdoor field experiments. Several …

Identification Of Necessary Conditions For Arctic Transport Of Smoke From United States Fires, Narasimhan K. Larkin, Jennifer L. Dewinter, Tara M. Strand, Steven G. Brown, Sean M. Brown, Sean M. Raffuse, Jonathan Callahan, Kenneth J. Craig, Robert C. Solomon, Hilary R. Hafner

Joint Fire Science Program Research Project Reports

The deposition of black carbon (BC), a dark absorbing aerosol, is a significant contributor to observed warming trends in the Arctic (Hansen and Nazarenko, 2004; Jacobson et al., 2007). Biomass burning outside of the Arctic, including wildland prescribed fires, is a major potential source of Arctic BC. Therefore, limiting or eliminating spring prescribed burning has been suggested to Congress as a BC reduction technique (e.g., Zender, 2007). However, there are large uncertainties in the current estimates of the sources, source regions, and transport and transformation pathways of BC transported to the Arctic region (Shindell et al., 2008; Hegg et al., …
