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...

Pre-plant soil fumigation is widely applied to control nematodes, soil-borne fungal pathogens, and weeds in vegetable crops. However, most of the research evaluating the effect of fumigants on crop yield and soil microbial communities has been done on single compounds despite growers mainly applying fumigant combinations. We studied the effect of different fumigant combinations (chloropicrin, 1,3-dichloropropene, and metam potassium) on soil properties, crop yield, and the soil bacterial and fungal microbiome for two consecutive years in a plastic-mulched tomato production system in Florida (U...

Noninvasive and nondestructive root phenotyping techniques under field conditions are needed to advance plant root science. Soil electrical parameters including capacitance and resistance hold potential to meet this need, although their specific ability to detect roots remains uncertain. In this study, we developed a two-phase root and soil permittivity model at high frequency enabling accurate and noninvasive prediction of root volume. The validation calculation showed that the two-phase model successfully predicts root volume with a minimal error of less than 1 % under the control conditions...

The USDA Forest Service, Forest Products Laboratory, was asked to inspect the main support timbers of a historic building at the Veterans Affairs (VA) Medical Center in Tomah, Wisconsin. This report summarizes the results obtained from the inspection and assessment. It includes a summary of observations, wood species identification, and recommendations.

Contrary to broad perceptions, high mountain streams are warming more slowly than low-elevation streams and rivers. Studies by Rocky Mountain Research Station (RMRS) scientists and their collaborators show that they will sustain populations of cold-water species, including fish such as threatened bull trout and cutthroat trout, even as the climate warms. This is also good news for other animals dependent on cold-water systems, including birds such as the American dipper and harlequin duck, mammals such as river otters, and insects such as stone flies and mayflies, which are critical to flyfish...
