This is a collaborative project between the National Park Service (NPS) and the University of Washington to use new satellite data to assess changes in several glaciers in North Cascades National Park (NOCA). Recent investigations have shown that the glaciers in the Washington Cascades are retreating rapidly in a warming climate. NPS has monitoring data from four glaciers at NOCA. These data will be analyzed with new WorldView stereo satellite data to produce digital elevation models (DEMs) with high accuracy for four NOCA glaciers, and to calculate volume changes in these glaciers. Expected products include four DEMs with auxiliary products (e.g., image data) and a final report that describes the methods and detected...
This is a collaborative project between the National Park Service (NPS) and Oregon State University (OSU) for the purpose of studying the genetic connectivity of pika populations in five NPS units. OSU researchers will use individual and population-based genetic analyses to systematically estimate genetic distances among individuals and gene flow among patches or populations in NPS units in two very different habitats (talus vs. lava beds). Genetic distances among individuals or gene flow among groups reflect (in part) the degree that individuals are related and that populations are interacting via dispersal. Thus, researchers will use variation in genetic distance or gene flow to infer how landscapes (e.g., dispersal...
The National Park Service and Portland State University will collaborate in a field-based project to accurately map the spatial extent and status of the rapidly changing glacial ice on Mount Rainier. In particular, areas of active (moving) ice will be distinguished from stagnant (non-moving) ice, which is of premier importance for hazard planning. In the future, glacier maps can be updated rapidly using remotely sensed data, and avoiding expensive future field efforts. Deliverables will include identifying the true spatial extents of the glaciers, including: rock and debris covered areas (usually not mapped correctly in earlier surveys), and stagnant (versus active, moving) ice. Additionally, the bedrock topography...

Over 50% of commercial and recreationally important fish species depend on coastal wetlands. In the Pacific Northwest, coastal wetlands, where the ocean meets the land, are highly productive areas that support a wealth of wildlife species from salmon to ducks. The tidal marshes, mudflats, and shallow bays of coastal estuaries link marine, freshwater, and terrestrial habitats and provide economic and recreational benefits to local communities. However, wetlands in this region and elsewhere are threatened by sea-level rise and other climate-related changes. According to a USFWS and NOAA report, between 2004 and 2009, 80,000 acres of wetland were lost on average each year, which is a significant increase from the previous...

What will the rivers of the Pacific Northwest look like in the future? Will they be stable or unstable? Will the waters be cold and clear or warm and muddy? Will they have salmon or other species? These questions motivated our two-year study of climate warming effects on headwater streams draining the Cascade Mountains. Using a novel combination of snow, geohydrology, and sediment transport models we assessed the vulnerability of stream channels to changing peak streamflow. Our snow modeling shows that with just a 2°C warming, snowfall shifts to rainfall at all elevations, peak snowpacks occur over two months earlier, and snowpacks are reduced by over half of historical values. Our geohydrology modeling shows that...

This project aimed to contribute to effective decision making in the region for the scientific community and general public. Resource managers in the Great Basin are dealing with significant questions regarding how best to make decisions in the natural and human systems in response to climate change. Vulnerability assessments and other tools are used for climate change adaptation, but their effectiveness is not widely understood or examined. Assessing these tools for their utility and for their ability to translate science into accessible and available information for users, including the general public, is critical for the future viability and sustainability of the Great Basin. This project applied social and policy...

Rocky Mountain Research Station scientists initiated a study in the 1990s on avian distribution and habitat associations within the Sky Islands. By re-measuring vegetation and bird populations following wildfires and applying climate change models, they will assess the singular and synergistic effects of climate change and wildfire and provide strategies for managing resilient forests and conserving the avian community structure. They will also continue and expand citizen science efforts to develop a long term avian monitoring plan, as well as simulation studies to provide optimal monitoring designs for avian species to detect changes from large-scale stressors.
