While land managers often prioritize reducing wildfire risk in the wildland-urban interface, the impact on regional air quality from mitigating wildfire spread has been less explored. We developed a framework to quantify wildfire contributions to smoke exposure and assess targeted land management strategies. This data-driven approach integrates fire emissions and smoke transport to generate a smoke risk index at 0.25° × 0.25° resolution. We deploy the smoke risk index in an...AuthorsKarina E.

- Deadwood is an important component of forest health and terrestrial carbon storage. However, the diversity of arthropods inhabiting deadwood and the biotic factors influencing decomposition remain poorly understood, partly due to the challenges associated with studying wood‐dwelling organisms. Ecoacoustic methods—non‐invasive and non‐destructive—offer a promising approach to investigating saproxylic arthropod communities. We tested and optimized ecoacoustic techniques (including recording duration, sensor attachment methods, and soundproofing strategies) for saproxylic detecting abundance...AuthorsKristy M.

- Following rapid climate change, tundra plant communities are experiencing extensive compositional shifts. A conservation concern is the potential encroachment of boreal species into the tundra (‘borealisation’). Tundra borealisation has been sporadically reported, but not systematically quantified. Here, we synthesised data from across 32 study areas, spanning 1137 plots and 287 vascular plant species, resurveyed between 1981 and 2023. We (i) quantified tundra borealisation as the colonisation and increase in abundance of Boreal and Boreal-Tundra species, (ii) assessed biogeographical,...AuthorsMariana García Criado, Isabel C.

- The escalation of wildfires in the USA, coupled with rising firefighting costs and decreasing workforce capacity, underscores the critical need to evaluate the efficiency and effectiveness of containment measures. However, the existing spatial data that records the locations and types of containment measures and wildfire perimeters contains numerous errors and redundancies. This paper presents a comprehensive fireline Quality Assurance and Quality Control dataset developed from the wildland firefighting operations data reported in the National Interagency Fire Center National Incident...AuthorsAlexander Arkowitz, Scott Ritter, Matthew P.

- In sectors based on renewable resources, foresight studies have often been macro‐scale, quantitative outlook studies. As a result, in the complex operating environment of the forest bioeconomy, the organizations and professionals of the emerging bioeconomic sector have not been able to fully utilize futures information in their decision‐making processes. This study sought to find solutions to this issue by utilizing a nested business environment framework (NEST framework) in signal interpretation as part of piloting interactive horizon scanning of the forest bioeconomy. In interaction with...AuthorsTuomas Mauno, Päivi Pelli, David N. Bengston, Jouni Pykäläinen, Teppo HujalaKeywordsSourceFutures & Foresight ScienceYear2025
- 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
- Anticipating plausible future ecosystem states is necessary for effective ecosystem management. We use climate analog-based impact models and a co-production process with land managers to project future vegetation changes for the state of Oregon, United States, (2041–2070, RCP 8.5) at a management-relevant spatial resolution (270-m). We explore multiple analog-based methodologies, evaluate analog model performance with contemporary validation, and leverage climate analogs to assess projection uncertainty by quantifying areas where multiple vegetation trajectories are plausible under a...AuthorsSvetlana V.

- Little is known about the structure of tropical forests despite its critical role in the provisioning of ecosystem services. Here we assess the vertical structure of forests in the Brazilian Amazon with a large-scale airborne LiDAR dataset. We show that fire has greater impact in the lowest forest strata, differently from selective logging and windthrow. We also find that secondary forests quickly recover or even exceed reference areas at the 1-10m height stratum but that full recovery for the 20-30m height stratum has not been achieved even after 35 years. Our modeling results suggest...AuthorsDenis Valle, Leo Haneda, Ismael Verrastro Brack, Jean Ometto, Ovidiu Csillik, Marcos Longo, Michael Keller, Danilo AlmeidaKeywordsSourceCommunications Earth & EnvironmentYear2025
- Quantifying fuel moisture content accurately is critical for understanding global vegetation flammability. While models representing changes in dead fuel moisture are relatively advanced, the mechanisms driving fluctuations in live fuel moisture content (LFMC) have been difficult to capture. Living plants make up a large proportion of the fuel complex for wildfires, yet linking plant and combustion science to advance our understanding of wildfire risk has, to date, been limiting. Developing mechanistic approaches to link these two disciplines will confer greater understanding and capacity...AuthorsTegan P. Brown, W. Matt Jolly, Elliott T. Conrad, Zachary Cope, Samuel C.
