- High spatiotemporal resolution air quality modeling is essential for air quality impact assessments and decision‐making for prescribed burns. Accurate representation of the heterogeneous distribution of fuels and the structure of smoke plumes requires high‐resolution modeling frameworks. In this study, we conducted simulations of prescribed burns in Fort Benning, Georgia, with BlueSky‐CMAQ and WRF‐SFIRE modeling frameworks and compared the differences between the results. BlueSky‐CMAQ was run at a 1‐km resolution, while WRF‐SFIRE operated at a 200‐m resolution, both generating outputs...AuthorsZongrun Li, Rime El Asmar, Susan O'Neill, Yongtao Hu, Haofei Yu, Yunyao Li, David J.

- Wildfires are increasing in severity, frequency and size, potentially threatening freshwater species that adapted under different disturbance regimes. However, few wildfire studies have comprehensively evaluated freshwater populations and assemblages following wildfire over broad spatial scales while accounting for post-fire salvage practices in the watershed. We reveal that stream vertebrate assemblages across thirty 4th order streams, spanning a range of both watershed fire severity and post-fire forest management extent, were minimally influenced by immediate effects of fire alone...AuthorsAllison G.

- The introduction and spread of the invasive annual grass Ventenata dubia (ventenata) has incited concern from land managers in the Inland Northwestern United States. Maps describing ventenata's distribution would be a valuable management asset but have not been developed. Techniques using satellite time-series have been used to detect annual grasses' unique phenological qualities (timing of biological events); however, detection is complicated by the co-occurrence of phenologically similar species. This study aimed to examine the capability of land surface phenology derived from fused...AuthorsTy C. Nietupski, Hailemariam Temesgen, Becky K. KernsKeywordsSourceEcological InformaticsYear2025
- This report presents a comprehensive social and economic monitoring plan and baseline assessment of the USDA Forest Service’s stewardship contracting program from 2014 to 2023. Stewardship contracting is a flexible tool that enables the Forest Service to achieve land management goals while working with non-federal partners and supporting local communities. The Ecosystem Workforce Program (EWP) at the University of Oregon, in partnership with the Forest Service, developed a national-level monitoring framework to evaluate the program’s effectiveness through ten key questions related to...AuthorsMichael R.

- Passive acoustic monitoring is an emerging approach in wildlife research that leverages recent improvements in purpose-made automated recording units (ARUs). The general approach is to deploy ARUs in the field to record on a programmed schedule for extended periods (weeks or months), after which the audio data are retrieved. These data must then be processed, typically either by measuring or analyzing characteristics of the audio itself (e.g. calculating acoustic indices), or by searching for some signal of interest within the recordings, e.g. vocalizations or other sounds produced by some...AuthorsZachary J.

- CO2 fertilization of the terrestrial biosphere is limited by nitrogen. Biological nitrogen fixation (BNF) is the dominant natural nitrogen source to the terrestrial biosphere and can alleviate nitrogen limitation but is poorly constrained in Earth system models (ESMs). Here, we compare terrestrial BNF from an ensemble of ESMs of the 6th Coupled Model Intercomparison Project to a new global synthesis of observations across natural and agricultural biomes. We find that compared to observations, ESMs underestimate agricultural BNF but overestimate natural BNF in the present day by over 50%....AuthorsSian Kou-Giesbrecht, Carla R. Reis Ely, Steven S.

- Aim: Surveying for a species of concern ahead of proposed activities that alter its habitat is routine practice in conservation and management. Such surveys may accumulate large datasets that could further elucidate trends in abundance and distribution. However, the as-needed surveying of proposed activities may impart a sample site selection bias on the data if used for another purpose. Management of a threatened, forest-nesting seabird offered an example of this. Here we assessed how resource management planning and survey requirements can bias clearance monitoring survey data collected...AuthorsRyan Baumbusch, Adam Duarte, James T.

- Motivation: SNAPSHOT USA is an annual, multicontributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of species interactions on daily activity patterns. Main Types of Variables Contained: SNAPSHOT USA 2019–2023 contains 987,979 records of camera trap image sequence data and...AuthorsRoland Kays, Michael V Cove, Alex Jensen, Benjamin R.

- The Northwest Forest Plan (NWFP) record of decision directs federal agencies to monitor the social and economic impacts of the NWFP in two ways: determine whether the supply of timber and nontimber resources is predictable and sustainable; and evaluate changes in local communities associated with federal forest management. The methodology for this 25-year NWFP report combines established practices for measuring timber and other forest resource supply trends with the application of novel social science research approaches. County-scale quantitative analysis of social and economic change...AuthorsElisabeth GrinspoonKeywordsSourceGen. Tech. Rep. PNW-GTR-1019.

- Biological nitrogen fixation (BNF) is the main natural source of new nitrogen inputs in terrestrial ecosystems, supporting terrestrial productivity, carbon uptake, and other Earth system processes. We assembled a comprehensive global dataset of field measurements of BNF in all major N-fixing niches across natural terrestrial biomes derived from the analysis of 376 BNF studies. The dataset comprises 32 variables, including site location, biome type, N-fixing niche, sampling year, quantification method, BNF rate (kg N ha−1 y−1), the percentage of nitrogen derived from the atmosphere (%Ndfa),...AuthorsCarla R.
