  • New research is helping understand the past and more accurately estimate future salmon recovery potential. Archival index redd counts and contemporary redd census data from Central Idaho’s Middle Fork Salmon River (MFSR) offer a glimpse of historical Chinook salmon (Oncorhynchus tshawytscha) spawning and rearing habitat.

  • Since 1992, the SRS Upland Hardwood Ecology and Management Research Work Unit has provided workshops and trainings to fulfill continuing education requirements for both federal and non-federal land managers. In 2020, scientists planned to introduce an updated Upland Hardwood Silviculture course to meet training needs of state partners in the southern region. However, the COVID-19 pandemic forced scientists to quickly modify the logistics and structure of this highly anticipated training. With assistance from SRS IT specialists, SRS scientists conducted an all-virtual short course. The course delivered the most up-to-date information about the management of upland hardwood forests to more than 100 foresters and natural resource practitioners.

  • Invasive species experience biotic and abiotic conditions that may not resemble their native environments. Scientists compared native and invasive niches of four forest pests to help predict a species’ potential range expansion and invasion potential and help guide monitoring efforts.

  • Inadvertently introduced in the northeastern United States in the 1930s, mile-a-minute weed is a highly aggressive invasive plant that is replacing native species in many areas of the Nation. While a biocontrol agent has been identified, finding and reaching dense patches of mile-a-minute weeds has been a problem for land managers. The solution may be drones carrying environmentally friendly pods packed with tiny weevils.

  • Trust is an essential element in building and maintaining successful partnerships with stakeholders and community members. Managers hoping to build, maintain, or restore trust with communities may want to focus on active communication, demonstrating competence, and showing how actions are in the best interest of the community.

  • New Forest Inventory and Analysis (FIA) plots are being installed across the Southern Research Station Experimental Forest Network. The purpose of these plots is to:Generate baseline data about tree attributes and forest health,Create a universal sampling method, andProvide an infrastructure for long-term complementary studies. This work will increase communication across experimental forests and offer foundational data that will be used to maintain and improve the health of our forests and other natural resources.

  • Naturally-occurring diseases can kill wild populations of insect pests that attack and damage trees. This study examines the interaction between the Douglas-fir tussock moth and a lethal pathogen. Understanding host-pathogen dynamics may enable the prediction of the severity and duration of outbreaks.

  • Environmental DNA methods are highly sensitive and accurate, making them ideal for detecting animals at low densities. However, this tool also comes with its own unique set of challenges when applied to efforts to eradicate invasive species. This research explores the use of eDNA for evaluating invasive species eradication efforts in streams and offers best practices for incorporating eDNA methods into invasive species removal projects.

  • U.S. coal, oil, natural gas, and wind energy are concentrated in the grassland states. As energy demand continues to increase, increasing pressure will be placed on North American grassland systems. This study reviewed and summarized the extent and ecological effects of energy development and production in the Great Plains grassland system of the United States.

  • The Latinx population is the largest minority population in the United States and is estimated to comprise 28% of the U.S. population by 2050. While research on Latinx outdoor recreation in urban areas and city parks has increased over the past twenty years, research on federal and state public lands such as National Forests and Parks has waned. The results from this study show a shift in Latinx use of federal and state public lands.

  • Climate connectivity - the ability of a landscape to promote or hinder species movement when responding to a changing climate - depends on multiple factors, including the distance organisms need to move to respond to climate change and the resistance they experience along their routes. Human land uses may reduce climate connectivity, making it harder for species to move in response to climate change.

  • Research by Northern Research Station scientists and their partners presents the first evidence supporting a long-held hypothesis that a tree’s evolutionary history is key to its susceptibility to nonnative herbivorous insects. This discovery has the potential to be a game-changer in predicting the impact of and managing nonnative insects.

  • Post-bark beetle outbreak snagfall dynamics create a multiple-decade legacy that will persist longer in high-elevation compared to lower-elevation forests. The persistence and fall rate of snags (standing dead trees) generated during bark beetle outbreaks have consequences for the behavior, effects, and suppression of potential wildfires, hazard tree and timber salvage operations, wildlife habitat, and numerous ecosystem processes.

  • QUIC-Fire is the first fast-running 3D-coupled fire-atmosphere model that incorporates high-resolution 3D vegetation structure, interactions between multiple firelines, and fire-atmosphere feedbacks, which are critical for predicting the behavior of complex ignition patterns common on prescribed fires. QUIC-Fire is intended to serve as a core component of a prescribed fire planning tool that will assist land managers in understanding how ignition patterns connect to fire effects and smoke impacts.

  • When responding to a wildfire, fire managers need to consider a lot of information, like terrain in the area, vegetation conditions, and weather forecasts. When this information is spread across multiple data sources and web platforms, it can be more difficult to understand fire hazards and prioritize resources on the fly. The new app WildfireSAFE integrates real-time data into a single, user-friendly web platform.

  • Hitchhiking seeds collected from refrigerated shipping containers can pose a significant invasive species risk, according to recent USDA Forest Service research at the Port of Savannah. Seaports-of-entry, where commodities arrive in the U.S. from overseas via sea transportation, are hotspots of nonnative plant diversity and are significantly different from nearby sites. Biological invasions by nonnative organisms have been repeatedly shown to detrimentally impact the environment and the economy of the nation.

  • Changes in climate and land use strongly shape water resource management, but understanding their joint impacts is extremely challenging. To reliably meet future drinking water demands, water utilities must understand potential impacts of climate and land use changes on water availability.This work underscores the need to consider system responses and outcomes when determining the impacts of hydrologic change on drinking water availability.

  • In the context of wildfire risk mitigation on private property, we used household survey data on both people’s willingness to take risks across a wide range of activities (for example, driving and financial investments) and how they would rate their property on several measures of wildfire risk (for example, amount of defensible space). We paired these responses with assessments of the same parcels conducted by a wildfire professional, then examined the relationship between risk preferences and wildfire risk mitigation using both the self-reported and objective measures.
