However, oak advance reproduction is scarce on more productive sites in the Missouri Outer Ozark Border Subsection where sugar maple has accumulated in the midstory. The purpose of our study was to identify barriers to accumulating competitive white oak advance reproduction in the Outer Ozark Border Subsection at different stages of the regeneration process, including seed germination, seedling establishment,...AuthorsAbby L.

- Although many species display relationships – both positive and negative – with various forest successional stages, researchers often rely on datasets that describe forest presence rather than forest age (i.e., National Landcover Database). In 2023, the USDA Forest Service introduced standardized region-specific mature and old-growth (MOG) forest definitions for the United States, but these definitions have not been readily integrated to address questions in ecology and conservation. Here, we introduce ‘mapMOG’—an open access R function that applies the recently adopted federal MOG...AuthorsDaniel J. Herrera, Christopher Schalk, Andrew Gray, Margaret Woodbridge, Deanna H.

- This resource bulletin consolidates data from the ninth complete survey of Tennessee’s forest resources which was conducted during the period 2015–2019 by the U.S. Department of Agriculture (USDA) Forest Service, Forest Inventory and Analysis (FIA) program in cooperation with the Tennessee Department of Agriculture Division of Forestry (TDF). Data on the extent, condition, and classification of forest land and associated timber volumes, as well as growth, removals, and mortality rates are described and interpreted. Data on forest health and forest landowner characteristics are also...AuthorsChristopher M. Oswalt, Sonja OswaltKeywordsSourceUSDA Forest ServiceYear2026
- 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 Massachusetts. 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...AuthorsForest Service.

- Open oak woodlands, once dominant across the Central Hardwoods Region of the United States, have been largely replaced by dense, closed-canopy forests following decades of fire suppression and land-use change. Silvopasture, the intentional integration of trees, forages, and livestock, may offer economic incentives for private landowners to restore these degraded woodlands while producing marketable livestock. Targeted goat browsing is a potential tool for shifting dense woodland systems toward open, silvopasture conditions. However, limited information exists on how browsing influences...AuthorsGina Beebe, Lauren S. Pile, Connor D. Crouch, Dacoda T. Maddox, Brian Davidson, Michael Stambaugh, Daniel C.

- Tidal wetlands sequester carbon (C) at much higher rates per area than other ecosystems, helping to offset C emissions. The burial of organic C in tidal wetland soils, “blue C”, is tightly linked to the cycling of nitrogen (N), which is a key pollutant and limiting nutrient for many ecosystems. The large fluxes of N in and out of tidal wetlands can have strong impacts on surrounding water quality. However, the global burial rate of “blue nitrogen” and its potential response to future sea‐level rise (SLR) and wetland extent changes have not been quantified. Here, we assembled a global...AuthorsJ. Adam Langley, Samantha K. Chapman, Le Wang, Tania L. Maxwell, Phillip Rivera, M. F. Adame, Ariane Arias‐Ortiz, Christina Asanopoulos, J. F. Blanco, Josh L.

- Trees offset many challenges endemic to developed areas, like the urban heat island effect and stormwater runoff. Research has shown that urban areas are racially segregated, and there are broad inequities in the distribution of trees; minoritized neighborhoods have less tree canopy (“canopy”). Most research focuses within major city boundaries, while the majority of Americans live in the broader metropolitan region in suburban or exurban communities. While suburbs and exurbs are growing faster than cities and becoming more demographically diverse, little is known about metropolitan canopy...AuthorsLindsay E. Darling, Dexter H. Locke, Christine R.

- Prescribed fire is an established means to reduce wildfire risk and accomplish silvicultural and cultural objectives via controlled consumption of fuels. Terrestrial laser scanning (TLS) has been demonstrated as a simple and efficient means to quantify fuel and vegetation conditions in terms of three-dimensional forest structure and occupied volume at the plot-scale; however, there is currently a lack of studies that explore a repeat time series of TLS measurements for documenting fire treatment efficacy over time. We used a time-series approach to repeatedly scan 40 monitoring plots six...AuthorsAaron E. Maxwell, Michael R. Gallagher, Samuel R. Stockton, Matthew C. Wozniak, Brenden E. McNeil, Julia A.

- Protected area (PA) managers balance the need to provide quality visitor experiences with other management objectives (e.g., conservation, economic use), particularly in multi-use agencies. Sustainability science has informed PA management, emphasizing consideration of economic, environmental, and social interactions. Sustainable management of outdoor recreation has received far less attention. Moreover, there has been a lack of agreement among PA managers about how sustainable outdoor recreation is defined, operationalized, managed, or monitored. Having a shared understanding of ‘sustainab...AuthorsLee K. Cerveny, Dale BlahnaKeywordsSourceSustainabilityYear2026
- Increasing terrestrial carbon storage can reduce atmospheric carbon dioxide levels as a climate mitigation strategy. Agricultural soil offers potential for persistent soil carbon sequestration. Mineral-associated organic carbon (MAOC) is generally more persistent than particulate organic carbon (POC), but it is unclear how much influence soil health and management can have on MAOC relative to climate and edaphic conditions. Soil samples from 196 agricultural fields on 77 farms throughout Vermont were fractionated by size to understand how these factors affect the amount and proportions of...AuthorsErin D.
