On Earth Day, 2022, the White House issued an executive order requiring federal agencies to inventory the mature and old-growth forests on Federal lands, to complete this inventory within a year of the order, and to make it available to the public. This order extended from the 2021 Bipartisan Infrastructure Law (i.e., the Infrastructure Investment and Jobs Act 2021), which invested $5.5 billion over 5 years to address some of the USDA Forest Service’s most pressing issues, including the increased risk of wildland fire, ecosystem restoration, and the conservation of old-growth forests. To compl...

Media stories highlighted accounts of migration away from city centers towards more rural destinations during the COVID-19 pandemic, but systematic research about how the pandemic changed migration in more rural destinations is only starting to emerge. This paper relies on U.S. Postal Service change-of- address data to describe whether and how established domestic migration systems changed during the COVID-19 pandemic, focusing on differences across the rural–urban gradient and by outdoor recreation resources. We find little evidence of massive urban exodus. We do find that out-migration from ...

However, this "dilution effect" is not consistently detected, and when present can vary strikingly in magnitude. Here, we use forest inventory data from over 25,000 plots (>1.1 million sampled trees) to quantify the strength of the dilution effect on dozens of forest pests and clarify why some pests are particularly sensitive to biodiversity. Using Bayesian hierarchical models, we show that pest prevalence is frequently lower in highly diverse for...

Peatlands are sources of bioaccumulating neurotoxin methylmercury (MeHg) that is linked to adverse health outcomes. Yet, the compounding impacts of climate change and reductions in atmospheric pollutants on mercury (Hg) export from peatlands are highly uncertain. We investigated the response in annual flow-weighted concentrations (FWC) and yields of total-Hg (THg) and MeHg to cleaner air and climate change using an unprecedented hydroclimatic (55-year; streamflow, air temperature, precipitation, and peatland water tables), depositional chemistry (21-year; Hg and major ions), and streamwater ch...

We assess the vulnerability of seven Alaska Native tribes in the Chugach region, which includes Prince William Sound (tribes in Chenega, Cordova, Qutekcak [Seward], Tatitlek, and Valdez) and the adjoining Kenai Peninsula (Nanwalek and Port Graham), to key climate and nonclimate stressors. This report supplements the interagency Climate Change Vulnerability Assessment for the Chugach National Forest and the Kenai Peninsula that was published in 2017. Over the next 50 years, all communities are generally expected to experience higher temperatures, with decreasing snowpack along the coast where t...

This report is a synthesis of current harvested wood product (HWP) carbon models available for use in the United States and Canada. As local, state, and national entities develop forest management objectives that address climate change mitigation, there is a need to consider the short- and long-term fate of carbon in HWPs. The goals of this synthesis were to (1) review and synthesize the functionality of current HWP carbon models; (2) describe the role of life-cycle assessment (LCA) to estimate overall greenhouse gas (GHG) implications of using HWPs instead of alternative nonwood materials or ...

Forest managers working in dry forest ecosystems must contend with the costs and benefits of fire, and they are seeking forest management strategies that enhance the resilience of forests and landscapes to future disturbances in a changing climate. An interdisciplinary science team worked with resource managers and stakeholders to assess future forest ecosystem dynamics, given potential climatic changes and management strategies, across a 23,000-ha landscape in the Lake Tahoe basin of California and Nevada in support of the Lake Tahoe West Restoration Partnership. We projected forest growth an...

Science, Technology, Engineering, and Mathematics (STEM) and Research Data Librarians collaborated with an international research team of conservation geneticists to create an instructional and practical guide combining genetic biodiversity initiatives and data curation. Over the course of two months, the academic librarians held multiple community-based Curate-A-Thons where an international group of students, researchers, librarians, and faculty researchers participated in tracking down publications and metadata for genomic sequence data, thus crowd-sourcing this effort of metadata enhancemen...

Tree mortality due to global change—including range expansion of invasive pests and pathogens—is a paramount threat to forest ecosystems. Oak forests are among the most prevalent and valuable ecosystems both ecologically and economically in the United States. There is increasing interest in monitoring oak decline and death due to both drought and the oak wilt pathogen (Bretziella fagacearum). We combined anatomical and ecophysiological measurements with spectroscopy at leaf, canopy, and airborne levels to enable differentiation of oak wilt and drought, and detection prior to visible symptom ap...

This paper proposes a surveillance model for plant pests that can optimally allocate resources among survey tools with varying properties. While some survey tools are highly specific for the detection of a single pest species, others are more generalized. There is considerable variation in the cost and sensitivity of these tools, but there are no guidelines or frameworks for identifying which tools are most cost-effective when used in surveillance programs that target the detection of newly invaded populations. To address this gap, we applied our model to design a trapping surveillance program...
