Of these, 44 were remeasured plots first established in 2008, and 27 were newly established plots including 17 plots established in cooperation with the Micronesia Challenge program. We recorded a total of 20 tree species and 53 dominant vascular plant species, including three invasive plant species. We inventoried four forest communities (lowland rainforest, agr...AuthorsJulian Dendy, Olaf Kuegler, Ashley D. Lehman, Wendolin Roseo. MarquezKeywordsSourcePNW-GTR-1036.

- Longitudinal data are essential to assessing change in environmental parameters over space and through time. This is particularly true in forest ecosystems where demographic patterns are controlled by many biotic and abiotic factors that may only be observed through repeated measures of tree (e.g., height, diameter, status), stand (e.g., tree density, litter depth), and site conditions (e.g., evidence of disturbance). Data from the United States Department of Agriculture Forest Service, Forest Inventory and Analysis Program (FIA), support a variety of research and reporting efforts in forest r...AuthorsJonathan Knott, Jianmin Wang, David Walker, Grant Domke, Songlin FeiKeywordsSourceEcosphereYear2025
- Climate change affects nearly every aspect of the interdependent biophysical and social systems in California’s Sacramento–San Joaquin Delta. Mitigating and adapting to these effects will require effective climate governance: referring to the actors, rules, and processes through which decisions are made to prevent and respond to climate change. How governance systems effectively achieve these goals has become an increasingly central question in climate social science and climate policy debates, both at global and local scales. This paper reviews the state of science on climate governance in th...AuthorsJessica Rudnick, Tanya Heikkila, Elizabeth Koebele, Tiffany Morrison, Chelsea BataviaKeywordsSourceSan Francisco Estuary and Watershed ScienceYear2025
- While research has documented clear regional differences in environmental attitudes and behaviors, less is understood about the role of shared moral values in shaping these variations. This gap poses a critical challenge to designing effective climate action strategies. Many environmental initiatives rely on “moral framing” to promote proenvironmental behavior, often targeting specific geographical areas like cities or counties. However, these strategies may falter if they fail to account for the unique moral landscapes that shape climate beliefs and actions in different regions. To maximize t...AuthorsFarzan Karimi-Malekabadi, Sonya Sachdeva, Morteza DehghaniKeywordsSourceThe Proceedings of the National Academy of Sciences NexusYear2025
- 1. Addressing social and ecological values is a central aim of democratic environmental management and policymaking, especially during deliberative and participatory processes. Agencies responsible for managing public lands would benefit from a deepened understanding of how various publics value those lands. 2. Federal land management agencies receive millions of written comments from the public on proposed management actions annually, providing a unique source of insights into how the public assigns value to public lands. To date, little attention has been directed towards methods for analy...AuthorsSarah K. MacFarland, Sonya Sachdeva, Spencer A. Wood, Joshua J. LawlerKeywordsSourcePeople and NatureYear2025
- Peatlands store significant amounts of carbon, which is released as greenhouse gases when peatlands are degraded. Restoration and rewetting can help prevent these emissions, while continuous monitoring is critical for evaluating their success. Using satellite-derived observations of essential climate variables, we conducted the first large-scale assessment of how peatland restoration influences land surface temperature (LST), albedo, and vegetation across 72 sites in North America and Europe. Our findings indicated that before restoration, degraded peatlands had a commonly lower daytime LST an...AuthorsIuliia Burdun, Mari Myllymäki, Rebekka Artz, Mélina Guêné-Nanchen, Leonas Jarašius, Ain Kull, Erik Lilleskov, Kevin McCullough, Mara Pakalne, Jiabin Pu, Jūratė Sendžikaitė, Liga Strazdina, Miina RautiainenKeywordsSourceEnvironmental Research LettersYear2025
- The U.S. Department of Agriculture, Forest Service, National Best Management Practices (BMP) program assists in meeting agency Clean Water Act objectives with nationally consistent monitoring. National BMP program monitoring protocols are used to evaluate BMP implementation (including planning) and effectiveness for most types of land disturbing activities that occur on national forests and grasslands. This report summarizes data from the first two full monitoring periods—federal fiscal years 2015–2016 and 2017–2018—for wildland fire, recreation, and water uses management protocols. Best manag...AuthorsPamela J. Edwards, Frederica Wood, Joan Y. CarlsonKeywordsSourceGen. Tech. Rep. NRS-233.

- We conducted a census of all facilities in California that purchase roundwood as well as facilities that purchase residuals from roundwood users. We also collected data from facilities in surrounding states that purchase roundwood from California. We asked facilities about their mill characteristics, employment, inputs, outputs, residual production and disposition, and sales values. In total, we identified 72 facilities in California, accounting for more than 1.6 billion board feet (BBF) Scribner of timber harvest, nearly 2.4 BBF Scribner of lumber and 2.1 million bone-dry units of mill residu...AuthorsSamuel G.

- Forest mesophication threatens the regeneration and potential future perpetuation of oak (Quercus spp.) forests throughout southern Appalachia and eastern United States (US). We explored methods to produce stand-scale oak site suitability maps, within the Nantahala National Forest in North Carolina, which can be used to prioritize site-specific treatments to allow for oak regeneration and recruitment using silvicultural strategies to reduce forest mesophication. To establish initial conditions, USDA Forest Service common stand exam quick plot protocol was followed, and plot data collected from...AuthorsQuentin Ikuta, John Zobel, Joseph Knight, Jonathan Knott, Brandon Stephens, Nicholas J.
