    Code Descriptions for “Managed wildfire: A strategy limited by terminology, risk perception, and ownership boundaries.”
    (University of Oregon, 2021) Davis, Emily Jane; Huber-Stearns, Heidi R.; Cheng, Antony S.; Deak, Alison; Evans, Alexander; Caggiano, Michael; McAvoy, Darren J.
    Federal land managers in the United States are permitted to manage wildfires with strategies other than full suppression under appropriate conditions to achieve natural resource objectives. However, policy and scientific support for “managed wildfire” appear insufficient to support its broad use. We conducted case studies in northern New Mexico and southwestern Utah to examine how managers and stakeholders navigated shifting barriers and opportunities to use managed wildfire from 2018-2021. Use of managed wildfire was fostered through an active network of civil society partnerships in one case, and strong interagency cooperation and existing policies and plans in the other. In both, the COVID-19 pandemic, drought, and agency direction curtailed recent use. Local context shapes wildfire response strategies, yet centralized decision making and policy also can enable or constrain them. Future research could refine understanding of social factors in incident decision making, and evaluation of risks and tradeoffs in wildfire response.

    Code Descriptions for “Spanning boundaries for managing wildfire risk in forest and range landscapes: Lessons from case studies in the western United States.”
    (University of Oregon, 2021) Davis, Emily Jane; Huber-Stearns, Heidi R.; Cheng, Antony S.; Deak, Alison
    Managing wildfire risk across boundaries and scales is critical in fire-prone landscapes around the world, as a variety of actors undertake mitigation and response activities according to jurisdictional and administrative boundaries; and available human, organizational, technical, and financial resources. There is a need to catalyze their coordination more effectively to collectively manage wildfire risk. We interviewed 102 people across five large landscape case studies in the western US to categorize how boundary spanning people, organizations, settings, concepts, and objects were deployed in range and forestlands to collectively address wildfire risk. Across all cases, actors spanned jurisdictional, conceptual, and administrative boundaries to create: 1) conductive settings for boundary work to occur; 2) concepts to communicate across boundaries; and 3) concrete objects as joint reference points, and to navigate challenges to implementing work on the ground. This work highlights context-specific ways to advance cross-boundary wildfire risk reduction efforts, and uses a boundary spanning lens to provide insight into how collective action in wildfire management evolves in different settings. This research also shows prescribed fire as a gateway for future collective action in wildfire risk, including managing naturally ignited wildfires for resource benefits or improved coordination and communication during wildfire suppression efforts.

    Code Descriptions and data for “Comparing social constructions of wildfire risk across media, government, and participatory discourse in a Colorado fireshed
    (University of Oregon, 2021-08-11) Jacobson, Meredith; Smith, Hollie; Huber-Stearns, Heidi R.; Davis, Emily Jane; Cheng, Antony S.; Deak, Alison
    This study examined how wildfire risk is framed by different entities and actors within a common region, during and after experiencing several large wildfire events. Using a social constructionist lens, we viewed wildfire risk as a fluid and variable concept that is socially constructed and framed through public discourse. Inconsistent social constructions of wildfire risk may pose challenges for effective wildfire risk governance and management, which requires the coordination of diverse entities including government, land managers, homeowners, and community groups. We sought to understand differing social constructions of wildfire risk within one region, the Northern Colorado Front Range, across four domains of social discourse: mainstream media coverage, governmental planning documents, a community collaborative group’s meeting notes, and Community Wildfire Protection Plans. Through multiple rounds of qualitative coding, we compared how values at risk, causes of risk, and solutions to mitigate risk are framed across discourse domains. We also identified which agencies, organizations, or other actors’ voices were most prominent within each domain. Our results show inconsistent framings of wildfire risk definition across the data, building upon past literature that has identified divides between fire suppression and mitigation work, as well as disconnects between media representations of fire and perspectives of resource managers and scientists. Lastly, we highlight two examples of cross-cutting discourses - public drinking water and smoke – as concepts that span boundaries and may have the power to generate broader coordination and support for wildfire policy solutions and action.

    Supporting Information for Fire presence affects patterns and controls on asymbiotic nitrogen fixation in seasonally flooded forests of southern Amazonia
    (University of Oregon, 2019) Bomfim, Barbara; Silva, Lucas C. R.; Marimon-Júnior, Ben H.; Marimon, Beatriz S.; Doane, Timothy A.; Horwath, William R.
    In this study, we focus on the biogeochemical consequences of fire on seasonally flooded (SF) forests of southern Brazilian Amazonia, where recent widespread rising tree mortality has been linked to changes in fire regimes. Recent studies have hypothesized that a quasi-permanent state-shift transition (from typical Amazon forests to open savannas) can occur when fire results in further depletion of already impoverished nutrient pools. Nitrogen (N) inputs via asymbiotic dinitrogen-N2 fixation (ANF) could be important for predicting the likelihood of post-fire forest recovery, but fire effects on ANF have yet to be quantified in this region. Here, we quantified ANF through combined field sampling and laboratory measurements using 15N-labeled dinitrogen (15N2) incubations, and quantified 14 biogeochemical parameters in surface (0−10 cm) and subsurface (10−30 cm) soils from burned and unburned areas within five SF forest stands selected to represent a gradient of fire disturbance, from low (once in 13 years) to high (five times in 13 years) frequency. We find that ANF rates are ~24% lower in burned relative to unburned surface soils, with over 50% of the variance in ANF explained by soil carbon (C) to N ratio and phosphorus (P) availability. Our data indicate that interactions between soil C:N:P stoichiometry and fire presence affect ANF in a predictable way. Taken together, these findings show that changes in soil carbon and nutrients explain a decrease in ANF with potential for long-term decline in C sequestration from altered successional trajectories in forest ecosystems of southern Amazonia.

    Supplementary Data Terrestrial Mollusk Location and Species Count
    (University of Oregon, 2017) Emery-Wetherell, Meaghan Marie; Mathew, Christine; Church, Cameron; Dellard, Ellie; Davis, Edward Byrd; Roering, Josh
    Many species of terrestrial mollusks are small and difficult to find, with poorly known ranges and habitat preferences. Because desiccation is a primary cause of mortality for many terrestrial mollusks, incorporating wetness as a habitat variable may improve survey results for different species of terrestrial mollusks. We compared presence and abundance data from terrestrial mollusk surveys in Tillamook Resource Area to two measures of relative wetness: topographic wetness index (TWI) and geomorphic features (landslides, debris-flow channels, etc.). Hurdle Model regression revealed a positive correlation between increased TWI and likelihood of presence or abundance for five species, and a negative correlation for four species. Overall species diversity and total mollusk count were negatively correlated with increased TWI, but the effect size was small (p = 0.02, R2 = -0.03). Our Kruskal-Wallis Analysis of Variance of TWI between species was significant (p<0.001), indicating terrestrial mollusks occupy significantly different wetness regimes - but this relationship was driven entirely by the wetness specialization of Hemphillia glandulosa. Our chi square analysis of topographic features found significant preferences of different species for different topographic types, which correlated loosely but not precisely to the preferences indicated by TWI. These results show that altering current terrestrial mollusk survey protocol to include geomorphic features (which are simpler and less time-intensive than calculating TWI) would increase detection likelihood of certain species, including Hemphillia glandulosa, a species protected under the Survey and Manage guidelines of the Northwest Forest Plan.

    Amazon Rainforest Microbial Observatory Metagenomes
    (University of Oregon, 2010-04) Bohannan, Brendan J. M.; Meyer, Kyle M.; Klein, Ann M.; Rodrigues, Jorge L. M.; Nusslein, Klaus; Tringe, Susannah G.; Mirza, Babur S.; Tiedje, James M.
    This data archive contains 79 files of quality-filtered, shotgun metagenomic DNA sequence data generated as part of the Amazon Rainforest Microbial Observatory (ARMO) project. Ten soil cores were collected from Amazon Rainforest Microbial Observatory in April 2010 (5 soil cores from primary rainforest and 5 from a 38 year-old converted pasture). Soil was sampled to a depth of 10 cm (after removal of the litter layer) using standard coring methods and homogenized. Samples were frozen on the spot, transported on dry ice, and stored at -80° C until extraction. DNA was extracted from five soil subsamples per core (i.e. 50 extractions per 10 soil cores). Metagenomic libraries were constructed from the 10 samples using the Illumina TruSeq kit with ~270 bp insert sizes according to standard protocol. Sequencing of 150 bp paired-end reads was performed on the Illumina HiSeq platform at the Joint Genome Institute. In total, 21 lanes (2-3 lanes per sample) were sequenced to produce 6.4 billion paired-end reads, resulting in an average of 636 million (±12%) reads per sample. Raw sequences were uploaded to MG-RAST (http://metagenomics.anl.gov), and paired-end reads were joined using fastq-join as part of the MG-RAST pipeline. Single end reads that could not be joined were retained. After merging paired-end reads, a total of 6.3 billion sequences with an average length of 171 bp were processed through the MG-RAST pipeline. All other pipeline options were left as default (i.e. trimming of low quality bases, removal of artificial replicate sequences, and filtering of sequences with greater than 5 ambiguous bases). Also included are two OTU tables (community matrices).
