However, we lack a clear understanding of how the structure of coastal forests is being altered by climate change drivers. Here, we used data from the Forest Inventory and Analyses program of the US Forest Service to examine structure and biomass change in forests along the mid-Atlantic, Southeastern, and Gulf coasts of the US. We selected plots that have been resampled at low (5 m) and mid (30–50 m) elevations in coastal areas of states from...AuthorsMarcelo Ardón, Kevin Potter, Elliott White, Christopher WoodallSourcePLOS ClimateYear2025
- BackgroundThe increasing extent and severity of wildfires in the western USA poses a significant challenge to managers and to society. Forest thinning and prescribed fire treatments reduce fire hazard and improve resilience to climatic stressors. However, expanding the pace and scale of forest management is hampered, in part, by limited understanding and exposure of interested parties and the public to fuel reduction treatments. Virtual tour applications provide an opportunity to extend tours of treatment demonstration areas to anyone with a computer and internet connection. Yet there is littl...AuthorsAlan H.

- Eastern spruce-fir forests, characterized by red spruce (Picea rubens) and balsam fir (Abies balsamea), cover millions of acres in the northeastern United States and southeastern Canada. Many spruce-fir forests are managed for wood production and wildlife habitat. To best manage these forests for the resources they provide, it is important to determine the stocking, that is, the size and number of trees in a given stand. The stocking provides different levels of growth and canopy closure, which informs managers when and how to thin the stand. Researchers from the U.S. Department of Agricultur...AuthorsJenna Zukswert, Laura KeneficSourceFSYear2025
- Catastrophic earthquakes induce significant, enduring vegetation disturbances through extensive landslides and geomorphological alterations. The post-earthquake vegetation recovery hinges on the disturbance severity, climatic variability, and strategic human intervention, yet understanding of these critical processes and their influences on eco-hydrological functions at the landscape level remains limited. This study aims to quantify the earthquake's impacts on vegetation structure and eco-hydrological functions and to elucidate the recovery mechanisms driven by climate variability and human e...AuthorsJiehao Zhang, Yulong Zhang, Matthew P.

- The complex social-ecological dynamics of homelessness in natural resource management have become increasingly apparent in recent years. Systematically understanding and engaging with these dynamics across sectors, disciplines, and landscapes has presented a conceptual and methodological challenge for both practitioners and researchers. Though some interdisciplinary research has expanded in recent years, the understanding it has fostered largely remains fragmented across disciplines, and its implications for practice are poorly understood. To help create connections across this fragmented dial...AuthorsSeamus R. Land, Monika M. DerrienKeywordsSourceLandscape and Urban Planning. 255(4): 105254.Year2025
- This paper describes ongoing research toward the development of a moisture risk index that is intended to give a quantitative indication of the risk of moisture performance issues for different wood-frame wall assemblies in different climates. The concept is like a Home Energy Rating System Index but for moisture performance of a wall assembly rather than whole house energy performance. The moisture risk index is envisioned as providing more granularity than existing pass/fail criteria or green/yellow/red risk assessments while requiring less computational effort than full probabilistic analys...AuthorsSamuel Glass, Charles R.

- Air leakage is one of the critical moisture sources that may compromise the structural integrity and air quality of wood-frame buildings. The present study investigates air leakage through typical North American oriented strand board (OSB) sheathing using a one-of-a-kind analytical chamber, the CARWASh, which is designed to generate temperature- and humidity-controlled outdoor and indoor conditions for the evaluation of water management performance and moisture dynamics of exterior wall assemblies. We establish a baseline estimate for air leakage through OSB sheathing in full-scale wood-frame ...AuthorsNatalia Farkas, Charles R.

- Surface checks, cracks, and splits can occur in wood when it dries out too rapidly. Wood expands and contracts with changes in moisture content in the hygroscopic range. Spatial differences in wood moisture content cause internal stresses, and cracks form when these moisture-induced stresses exceed the tensile strength of the material. Large moisture gradients may occur in mass timber products, such as glue-laminated timber (glulam) and cross-laminated timber (CLT), at multiple points during and after exposure to moisture during the construction process, followed by abrupt changes in the indoo...AuthorsSamuel Glass, Natalia Farkas, Samuel Zelinka, Graham Finch, Nate HelbachKeywordsSourceProceedings paperYear2025
- Long-term planning is crucial in forestry, where decisions often need to be made decades in advance. However, anticipating the future is difficult because changes are happening faster and becoming more complex. In addition, many changes that could affect forestry— for example, social trends, technological advances, and economic disruptions—come from fields outside of forestry.AuthorsCherie LeBlanc Fisher, David BengstonKeywordsSourceFSYear2025
- The 1964 Wilderness Act famously defines wilderness as an area “untrammeled by man.” But what does it mean to “trammel” the wilderness? Many have interpreted trammeling as any intentional human action or manipulation that affects wilderness ecosystems, which means that any management intervention, even one aimed at helping a wilderness area’s natural conditions, must be considered a trammeling action.AuthorsJay Thomas, Clare Boerigter, Sean Parks, Jonathan LongKeywordsSourceScience You Can Use (in 5 Minutes), January 2024.
