Projected increases in extreme flooding events and shifting disturbance regimes create challenges for tree regeneration. Forest managers are considering the use of enrichment planting to increase tree species diversity, but limited information is available that quantifies the interactions between the flooding and shade tolerances of candidate tree species. We used a microcosm experiment to manipulate shade and flooding conditions to determine the effects on early survival,...AuthorsGwendolen J. Keller, Dustin Bronson, Robert A. Slesak, Marcella A.

- The forestry sector plays a significant role in nature-based climate solutions. This paper is a comparative review and analysis of forest carbon offset protocols in compliance carbon markets in Australia, California, China, New Zealand, and U.S. Northeast. Our results show variations in protocol designs, particularly in relation to additionality, permanence, non-leakage, and monitoring, reporting and verification (MRV), as well as regarding the fungibility between industrial carbon reduction and forest-based carbon offset. These results may have implications for national or subnational...AuthorsLili Li, Daiwei ZhangSourceForest Policy and EconomicsYear2024
- The biodiversity impacts of agricultural deforestation vary widely across regions. Previous efforts to explain this variation have focused exclusively on the landscape features and management regimes of agricultural systems, neglecting the potentially critical role of ecological filtering in shaping deforestation tolerance of extant species assemblages at large geographical scales via selection for functional traits. Here we provide a large-scale test of this role using a global database of species abundance ratios between matched agricultural and native forest sites that comprises 71...AuthorsFangyuan Hua, Weiyi Wang, Shinichi Nakagawa, Shuangqi Liu, Xinran Miao, Le Yu, Zhenrong Du, Stefan Abrahamczyk, Luis Alejandro Arias-Sosa, Kinga Buda, Michał Budka, Stéphanie M.

- Oak wilt, caused by the pathogen Bretziella fagacearum, is a destructive disease on oak (Quercus) species in the United States. Established methods to control the belowground spread of oak wilt are not appropriate in all circumstances; thus, forest health managers have a strong need for alternative methods for disease control. We evaluated the effectiveness of operational stump excavation treatments (i.e., “root rupture” method) applied between. 2004. and 2014 to control belowground spread of oak wilt on two forests in northeast Wisconsin, USA. The root rupture method achieved a high level...AuthorsAnna Yang, Linda Haugen, David Mausel, John Lampereur, Tommy Stueck, Rebecca Montgomery, Jennifer JuzwikSourceJournal of ForestryYear2024
- Forest inventory estimates of annualized net growth, removals, and mortality provide a standardized metric for a wide range of management and policy assessments. Commonly, plot-level annualized values are determined by dividing the periodic change by the length of the time interval. Subsequent estimation of means constitutes a mean-of-ratios (MOR) estimation approach. However, due to potential bias concerns for the MOR estimator, the ratio-of-means (ROM) estimator is generally preferred by forestry practitioners. National forest inventory data from six states in the United States were used...AuthorsJim Westfall, Mark D. Nelson, Christopher B. EdgarKeywordsSourceForest ScienceYear2024
- Loss on ignition (LOI) is a common method for determining organic matter in soils. Mineral soil organic carbon content has been shown to be approximately 50%–58% of the organic matter in many soils, but the carbon fraction of LOI can actually be much lower——particularly in Spodosols. We leveraged data available in the International Soil Carbon and National Ecological Observatory Networks to evaluate departures from the common 50% rule. We offer empirical equations that more accurately predict C:LOI with depth and genetic horizon in Spodosols. These equations enable more accurate soil C...AuthorsGrady J. Boyle, Evan Kane, Lucas E.

- Less advantaged areas have fewer and smaller trees. More advantaged neighborhoods have more and larger trees. Local socioeconomics relates to tree species diversity and composition. Tree canopy cover, not impervious cover, is correlated with community advantage.AuthorsJordan Jessamy, John E. Drake, David J. Nowak, John C. StellaKeywordsSourceLandscape and Urban PlanningYear2024
- Sialia sialis (Eastern Bluebird), a secondary cavity nester, often nests in anthropogenic structures, particularly nest boxes established throughout its range. We describe 3 observations of Eastern Bluebird nests at 2 photovoltaic (PV) solar facilities in eastern New York. At one facility, we observed an open-cup nest on the PV steel support structure, while at another, we observed 2 nests within structures mimicking cavities. At least 2 nests were likely successful. To our knowledge, these are the first documented occurrences of Eastern Bluebird nests within PV solar facilities in the...AuthorsAmanda L. Klehr, Alexis N.

- Numerous studies report proximity to land cover edges decreases avian nesting success, yet variation among species, sites, and nesting guilds obscures overall patterns. Nest success is a key demographic parameter, and edges are often created from anthropogenic disturbance; therefore, further understanding of nest success and edges should inform bird conservation efforts. We performed a meta-analysis to examine effects of edges on mature forest and shrubland bird nest survival in eastern North America. Sixteen studies fit our inclusion criteria, comprising data for 11 mature forest and 9...AuthorsMichael Akresh, Savannah McInvale, David KingKeywordsSourceJournal of Field OrnithologyYear2024
- This paper summarizes issues related to how wind is measured or interpreted from atmospheric models. It is based on conversations at a workshop held in Minneapolis, MN in May 2023. We discuss measurement protocols affect the wind speed and direction values, and how atmospheric models are not representative of point-observations or time-mean winds. These discussions are tied to real-world implications for fire management. We propose several areas of research or tool development that could improve wind information available to prescribed and wildfire management.AuthorsBrian Potter, Kara Yedinak, Jay J.
