These drivers affect carbon (C) stocks at ecosystem to regional scales, in turn affecting processes such as forest regeneration, hydrologic and biogeochemical cycling, and social and economic systems. We quantified land use change and forest management effects on C stocks in the Gulf Coastal Plain, focusing on soils, using two complementary approaches: meta-analysis of published literature and analysis of forest inventory data. Land use change had larger effects than forest...AuthorsLucas E. Nave, Kendall DeLyser, Grant M. Domke, Scott M. Holub, Adrienne B. Keller, Darren Miller, Kevin A.

- Fire suppression in the upper U.S. Midwest has led to the expansion of flammable coniferous ladder fuels, necessitating precise tracking of conifer species basal area (BA) for fire risk management. This study benchmarks four subset-selection pipelines—xPLS, GA-xPLS, RF-xPLS, and SVR-xPLS—to optimize the fusion of high-dimensional, collinear data from Sentinel-2, Landsat-9, and LiDAR sensors. Using 141 field plots in Minnesota’s Kawishiwi Ranger District of the Superior National Forest, we evaluated 175 predictors against eight BA response variables. Results show that RF-xPLS provided the...AuthorsNasrin Salehnia, Peter Wolter, Brian R. R. Sturtevant, Dalia A. IossifovKeywordsSourceRemote SensingYear2026
- Forests can occur across a continuum of urban-rural land-use contexts. Forests in cities (also referred to as forest patches, urban woodlots, urban forest fragments, or urban forested natural areas) are ecologically akin to wildland forests, but located in dense, urban landscapes. Here, we examine the opportunities and constraints for managing oak forests in cities to demonstrate the value of leveraging urban forests to develop and test adaptive management strategies for oak forests. Oaks dominate eastern United States forest types but face widespread regeneration failure across the...AuthorsM.R. Piana, Richard Hallett, Vince D'Amico, Nancy Falxa Sonti, T.L.E.

- The U.S. Department of Agriculture (USDA), Forest Service, Forest Inventory and Analysis (FIA) program provides this resource update yearly as an overview of forest resources in Minnesota. These estimates are derived from field data collected across a systematic network of fixed-radius forest monitoring plots located on both public and private land. New updates are provided annually as a subset of plots within the State are remeasured. Each year, field crews visit and measure a subset of all FIA plots across the entire State (the size of the subset varies by State and year). Combining all...AuthorsForest Service.

- In the northeastern United States, both hardwood and conifer forests have developed on sites with contrasting soils, allowing an examination of the effect of site and forest type on ecosystem nutrient cycling. We measured biomass production and nutrient fluxes in northern hardwood and conifer stands at three sites differing in soil fertility. We found that leaf, root, and wood concentrations of calcium (Ca), magnesium (Mg), and potassium reflected differences in soil base cation availability, while concentrations of nitrogen (N) and phosphorus (P) were more consistent across sites....AuthorsRuth D.

- Observations of atmospheric carbon dioxide (CO 2) are expected to play a critical role in monitoring, reporting, and verification designed to track progress toward the reduction goals of greenhouse gas emissions. In this study, we construct a comprehensive regional carbon budget for seven National Climate Assessment regions of the contiguous United States (CONUS) over 2015–2020. We demonstrate that lateral carbon movement across regions, along with their resulting endpoint CO 2 emissions, represent a major contributor to the interpretation of regional net surface‐atmosphere fluxes of CO 2...AuthorsB.

- Drought is a natural part of the Southeastern United States climate and a threat to agricultural productivity and profitability. Whether slow developing or rapid onset, drought can have severe impacts on agricultural crops and livestock depending on its timing, severity, and length. Drought is expected to become increasingly common in the Southeast due to increasing temperatures, longer dry periods between rain events, and growing water demand across the region. To help producers remain resilient and productive in the face of this threat, the U.S. Department of Agriculture Southeast...AuthorsLisa L. BaxterKeywordsSourceUSDA Forest ServiceYear2026
- Tropical forests are major contributors to the global carbon budget but are affected by disturbances such as hurricanes, which cause extensive yet spatially variable tree damage and mortality. High-resolution maps of forest aboveground biomass (AGB) and its temporal change aid in quantifying disturbance impacts, assessing resilience, and supporting forest management. This study presents wall-to-wall, high-resolution mapping of pre- and post-hurricane AGB and AGB change across Puerto Rico. The maps represent forest AGB measured 0–2 years before and after two major hurricanes (Irma and...AuthorsNafiseh Haghtalab, Tamara Heartsill Scalley, Tana E. Wood, J.

- Growing evidence has shown that, apart from local environmental factors, changes in landscape-level factors by accelerated land-use change can also shape soil pathogenic fungal diversity. However, the global representativeness of such patterns remains unclear. Here, we assess how pathogenic fungal diversity in 511 soil samples worldwide responds to landscape factors, including landscape complexity index based on eight landscape metrics and quantity of different land cover types across six spatial scales (i.e., surrounding landscape, 250m to 10,000m radii from the sampling coordinate).
