- Planners and managers of the recreation segment of the Salmon Wild and Scenic River (WSR) will eventually need to develop a user capacity, a monitoring plan, and a lands and facilities plan. To support these needs, we conducted a river user survey in the high-use season of 2021 and 2022, with 719 surveys distributed, yielding 332 usable surveys (46% response rate); which represents the second phase of research support (following a river use monitoring study in the high-use season of 2020). Below we highlight select findings.AuthorsChris A.

- Today it is recognized that wilderness has many dimensions, at once touching upon history, ecology, culture, mystery, risk, management, and personal experiences. The evolution of the wilderness concept, and how it is perceived, is influenced by diverse cultural perspectives, a continually expanding understanding of how humans are supported by nature, and existential threats to humanity, both socioeconomic (e.g., income inequality, access to nature and natural resources) and environmental (e.g., climate change, biodiversity loss). The primary purpose of this chapter is to review and...AuthorsVance G. Martin, Alan E. Watson, Chris A. Armatas, Amy LewisKeywordsSourceWaveland Press, Inc.Year2025
- Whitebark pine (WBP; Pinus albicaulis) is a five-needle conifer tree species native to the western United States (US) and southwestern Canada. In the US, this ecologically important species is listed as ‘threatened’ under the Endangered Species Act because of population declines from compound stressors, including climate change, introduced white pine blister rust (WPBR), widespread outbreaks of mountain pine beetle, and altered fire regimes. Species recovery depends primarily on planting WBP seedlings that are resistant to WPBR, but suitable planting locations are likely to shift under...AuthorsSean A.

- Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α-diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e., γ-diversity), either due to reduced β-diversity amplifying diversity loss or increased β-diversity dampening diversity loss. Additionally, studies often focus on taxonomic diversity, while other important biodiversity components, including phylogenetic diversity, can exhibit differential responses. Here, we evaluated how agricultur...AuthorsToby P. N. Tsang, A. A. Amado De Santis, Gabriela Armas‐Quiñonez, John S.

- Cross-laminated timber (CLT) is an emerging sustainable construction material with the potential to replace concrete. Life cycle assessment (LCA) has been widely applied to quantify the environmental impact of CLT materials and buildings. However, current research on CLT LCA mainly focuses on softwoods, lacking reports on hardwood CLT. Despite the less frequent utilization of hardwood by CLT manufacturers, hardwood CLT is technically feasible and provides value-added uses for low-quality timber. This study developed a cradle-to-gate life cycle modeling framework to produce hardwood CLT in...AuthorsJinghan Zhao, Jingxin Wang, Levente Denes, Zhichao Liu, Nathaniel Anderson, Richard Bergman, Kai Lan, Wanhe HuKeywordsSourceJournal of Cleaner ProductionYear2025
Expanding biodiversity monitoring in the southwestern United States with passive acoustic monitoring
Wildlife monitoring technologies like passive acoustic monitoring (PAM) show great promise in overcoming biodiversity monitoring challenges over broad spatial scales. We demonstrate that PAM can be an effective monitoring approach for wildlife species and communities in the southwestern United States. After collecting >51,000 hours of audio data in the Cibola, Gila, and Kaibab National Forests, we processed data with the BirdNET algorithm. We confirmed that BirdNET can currently identify at least fifty-two species, including six species of management interest: the Mexican spotted owl...AuthorsJamie S. Sanderlin, Gavin M.

Norman, Jack WilliamsKeywordsSourceThe Southwestern NaturalistYear2025- Across ecosystems and biomes, most species in biological communities are rare. Many studies discount rare species when examining biodiversity patterns, assuming that common species are most influential for ecosystem functioning. There is growing evidence, however, that rare species contribute unique functions in many ecosystems; thus, discounting them produces misleading conclusions about how biodiversity is changing in the face of natural and anthropogenic forces. Rare species are more likely to be missed by multi-species sampling designs and are thus particularly vulnerable to detection...AuthorsAna Kuile, An Bui, Austen Apigo, Shelby Lamm, Megan Swan, Jamie S.

- Background: Increasing wildfire area burned has left millions of hectares in the western United States (US) in need of reforestation. Recent federal legislation allows for increased investments in tree planting to address the backlog of planting needs in previously burned areas. To support post-fire planning and assessment, we developed Regenmapper, a web-based decision support system (DSS) that provides spatial information on natural regeneration potential within post-fire environments. The program is freely available from a web browser (https://alpheus.dbs.umt.edu/regenmapper/) and is...AuthorsZachary Holden, Ellen Jungck, Kimberley T. Davis, Dyer A.

- Anthropogenic reshaping of landscapes can increase landslide activity. One example of heavily modified, landslide-prone landscapes is the Appalachian region, which hosts weak geologic strata, steep slopes, a humid climate, geologically recent river incision, and large-scale landscape modifications resulting from surface mining. Surface mining conducted before the Surface Mine Control and Reclamation Act (SMCRA) of 1977 did not require reclamation to approximate original contour, so remnant highwalls and mine benches are common throughout Appalachia. This study investigated the occurrence...AuthorsMuhammad Ali, Aaron E. Maxwell, Charles Shobe, Sarah FarhadpourSourceEnvironmental & Engineering GeoscienceYear2025
- The National Land Cover Database (NLCD), developed through the Multi-Resolution Land Characteristics Consortium, was initiated 30 years ago and has continually provided critical, Landsat-based land-cover and land-change information for the United States. Originally launched to address the lack of national-scale, moderate-resolution land-cover data, NLCD has evolved from the pioneering 1992 dataset into a comprehensive, annually updated product suite. Key innovations include the introduction of impervious surface mapping, forest canopy mapping, standardized Landsat mosaics, national-scale...AuthorsTerry Sohl, Suming Jin, Jon Dewitz, James Wickham, Jesslyn Brown, Stephen Stehman, Nathaniel Herold, Karen G.
