A substantial portion, 39 %, of forests in the United States are owned by families, individuals, trusts, estates, and family partnerships, collectively referred to as family forest owners. There are many programs and services intended to help family forest owners conserve and better manage their land, but participation rates are relatively low, the efficacy of many programs has been called into question, and the social equitability of access is largel...AuthorsBrett J.

- Ecological theory predicts that consumers should be co-limited by resource quantity and quality, given widespread consumer-resource nutritional imbalances. We used 25 estimates of annual community secondary production (ACSP) of stream macroinvertebrates to assess the relative roles of basal resource quantity (leaf litter standing stock [LLSS]) and quality (% nitrogen and % phosphorus of leaf litter) in modulating patterns of production in forest streams. We also tested the effects of hypothesized indirect drivers (stream discharge and inorganic nutrient concentrations) on basal resource qualit...AuthorsLee M. Demi, Phillip M. Bumpers, Wyatt F.

- The U.S. Department of Agriculture, Forest Service is required to monitor National Forest System (NFS) lands to assess whether management plans are maintaining or restoring ecological integrity. As part of this monitoring effort, each planning unit is required to select at least one focal species - or one focal species assemblage - that represents a specific aspect of ecological integrity or management plan effectiveness. The planning unit can then make inferences about ecological integrity by monitoring this focal species or assemblage. Although selecting a focal species may seem simple, it c...AuthorsErin Taylor, Jamie S. Sanderlin, Jennifer E.

- In the United States, ecosystems regularly experience wildfires and as fire seasons lengthen, fires are becoming a more important disturbance. While all types of disturbance have impacts on the carbon cycle, fires result in immediate emissions into the atmosphere. To assist managers in assessing wildland fire impacts, particularly on federally managed land, we developed estimates of area burned and related emissions for a 21-year period. These estimates are based on wildland fires defined by the interagency Monitoring Trends in Burn Severity database; emissions are simulated through the Wildla...AuthorsCoeli M. Hoover, James E.

- In Michigan, United States of America, where Asian parasitoids were released to manage emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), we monitored four native parasitoids that also attack the invasive beetle – Atanycolus cappaerti Marsh and Strazanac, A. simplex (Cresson), and Spathius laflammei Provancher (all Hymenoptera: Braconidae), and Phasgonophora sulcata Westwood (Hymenoptera: Chalcididae) – using yellow pan traps and tree dissections. Adult A. cappaerti, followed by A. simplex, had the broadest seasonal activity, S. laflammei was captured primarily in the ...AuthorsToby R. Petrice, Therese M. Poland, Leah S. Bauer, John S.

- Rapid ‘ōhiʻa death (ROD), caused by fungal pathogens Ceratocystis lukuohia and Ceratocystis huliohia, is devastating ʻōhiʻa (Metrosideros polymorpha), the keystone forest tree species of Hawaiʻi. Ceratocystidaceae fungi produce fruity volatile organic compounds (VOCs) and sticky sexual spores, suggesting they are adapted for insect dispersal. In this study, we explored chemical signaling of the causal agents of the ROD disease complex and how those VOCs mediate ambrosia beetle (Coleoptera: Curculiondiae: Scolytidae)-plant interactions. Four species of ambrosia beetles (Xyleborinus saxesenii, X...AuthorsKylle Roy, Eva Brill, Dan Mikros, Kelsey Tobin, Jennifer Juzwik, Brandon Mcnellis, Douglass Jacobs, Lisa Keith, Dong H.

- Forest drought monitoring tools are crucial for managing tree water stress and enhancing ecosystem resilience. The Forest Drought Response Index (ForDRI) was developed to monitor drought conditions in forested areas across the contiguous United States (CONUS), integrating vegetation health, climate data, groundwater, and soil moisture content. This study evaluated ForDRI using Pearson correlations with the Bowen Ratio (BR) at 24 Ameri- Flux sites and Spearman correlations with the Tree-Ring Growth Index (TRSGI) at 135 sites, along with feedback from 58 stakeholders. CONUS was divided into four...AuthorsTsegaye Tadesse, Stephanie Connolly, Brian Wardlow, Mark Svoboda, Beichen Zhang, Brian A. Fuchs, Hasnat Aslam, Christopher Asaro, Frank H.

- Tree regeneration in northern temperate and southern boreal forests is threatened by multiple factors, including over-browsing by ungulates such as white-tailed deer (Odocoileus virginiana). However, characterizing the effects of deer browse on tree regeneration at regional scales has been challenging due to (a) the lack of reliable indicators of browsing intensity and (b) the fact that browsing impacts are likely to vary by seedling size yet coarse metrics are often used to capture this seedling attribute. To address these challenges, we modeled effects of white-tailed deer browse and other b...AuthorsLucas B. Harris, Melissa A. Pastore, Anthony W.

- Ecological responses to climate change occur across vastly different time-scales, from minutes for physiological plasticity to decades or centuries for community turnover and evolutionary adaptation. Accurately predicting the range of ecosystem trajectories will require models that incorporate both fast processes that may keep pace with climate change and slower ones likely to lag behind and generate disequilibrium dynamics. However, the knowledge necessary for this integration is currently fragmented across disciplines. We develop ‘ecological acclimation’ as a unifying framework to emphasize...AuthorsMichael Stemkovski, Joey R. Bernhardt, Benjamin Wong Blonder, John B. Bradford, Kyra Clark‐Wolf, Laura E.

- Climate change is reducing snowpack across temperate regions with negative consequences for human and natural systems. Because forest canopies create microclimates that preserve snowpack, managing forests to support snow refugia—defined here as areas that remain relatively buffered from contemporary climate change over time that sustain snow quality, quantity, and/or timing appropriate to the landscape—could reduce climate change impacts on snow cover, sustaining the benefits of snow. We review the current understanding of how forest canopies affect snow, finding that while closed-conifer fore...AuthorsMelissa A. Pastore, Sarah J. Nelson, Elizabeth A. Burakowski, Alexandra R.
