          Climate Change Drives Productivity of U.S. Forests

							Around the world, forests are critical land-based carbon sinks (places where carbon is pulled from the air and stored). NRS scientists wanted to know if climate change is affecting the productivity of U.S. forests in different regions of the country which could, in turn, decrease their effectiveness as carbon sinks. They used modeling techniques to estimate productivity trends for eastern and western U.S. forests.

          Population Growth Projected to Drive Increase in Outdoor Recreation

							Eric White, a research social scientist with the USDA Forest Service Pacific Northwest Research Station, and cooperators at the University of Georgia researched the status and potential future trends of outdoor recreation in the United States. They found continued strong participation in recreation and evidence that public forests were key providers of recreational opportunities. The researchers projected slight declines in the share of the population engaging in recreation but continued increases in the total number of people recreating outdoors because of population growth.

          Scientists Develop a New Approach to Measuring Lava Flows During Volcanic Eruptions

							Gordon Grant, a research hydrologist with the Pacific Northwest Research Station, applied a theory he first developed for rivers to a fundamental problem in predicting the impacts of volcanic eruptions: how much lava is flowing out of a volcano over time. His critical flow theory predicts that the wavelengths of standing waves in both water and lava can be used to estimate the depth and velocity of the flow. A team of scientists tested this idea using data from the 2018 Kilauea eruption in Hawaii and found that their estimates were very close to other flow measurements.

          A New Approach to Assessing Environmental Injury from Industrial Spills and Contaminants

							Measuring the potential impact of environmental stressors on natural resources is difficult because it involves complex interactions among environmental factors. To address this challenge, a team of scientists with the Pacific Northwest Research Station and the U.S. Geological Survey used a novel approach to develop a decision-aiding tool that assesses the potential injury to natural resources from the effects of industrial contaminants and pollutants.

          Targeted Grazing Supports the Coexistence of Bees and Livestock

							Rangelands provide habitat for a host of species, including invertebrates like native bees, and forage for livestock. A group of scientists set out to understand how livestock grazing may affect bees in two community types in Oregon. They found that moderate grazing in bunchgrass ecosystems was compatible with bee presence, while grazing in riparian meadows decreased flower, but not bee, abundance and diversity. Their research results can help inform grazing strategies to benefit livestock producers and pollinators.

          New Tool Provides Insight on Fate of U.S. Pacific Coastal Wetlands Under Rising Sea Levels

							Coastal wetlands are highly valued for their role in supporting critical ecological functions and ecosystem services, but these ecosystems are vulnerable to sea-level rise resulting from climate change. To inform coastal wetland management under changing sea levels, scientists with the Pacific Northwest Research Station and the U.S. Geological Survey worked together to develop a new model that predicts the potential impact of ongoing sea-level rise on the resilience of wetlands along the U.S. Pacific coast.

          Looking Beyond Stream “Best Management Practices” to Support Amphibian Conservation

							Stream Best Management Practices guide the management of aquatic and riparian biodiversity in forests. These practices often address habitat concerns through the application of riparian buffers—streamside areas of natural vegetation maintained to protect stream habitats. Rather than universal application of fixed-width buffers, a portfolio of “beyond best management practices” may better address sensitive species like amphibians that require a variety of habitats to survive.

          Heavy Metals in Moss Guide a Community Science Environmental Justice Investigation in Seattle, Washington

							Communities near industrial areas can experience heavy metal air pollution that standard air monitoring networks do not detect. Scientists with the Pacific Northwest Research Station and community members in two Seattle neighborhoods adjacent to industrial sites measured and mapped heavy metals in moss samples from urban trees. Local moss had higher levels of toxic metals than moss from other urban areas, leading community members to investigate the issue further.

          Unusual late-fall wildfire in a pre-Alpine European beech  forest reduced fine roots in the shallower soil layer and shifted very fine-root growth to deeper soil depth

							After an unusual, late-fall wildfire in a European beech forest in the pre-Alps of northern Italy, the finest roots (0‒0.3 mm diameter) were generally the most responsive to fire, with the effect more pronounced at the shallowest soil depth.
