Assessing Climate Change Impacts on Pacific Lamprey and Pacific Eulachon For thousands of years, Pacific lamprey and Pacific eulachon have been important traditional foods for Native American tribes of the Columbia River Basin and coastal areas of Oregon and Washington. These fish have large ranges – spending part of their lives in the ocean and part in freshwater streams – and they require specific environmental conditions to survive, migrate, and reproduce. For these reasons, Pacific lamprey and Pacific eulachon are likely threatened by a variety of climate change impacts to both their ocean and freshwater habitats. However, to date, little research has explored these impacts, despite the importance of these species to tribal communities. This project will evaluate the effects of...

In recent years, climate variability on annual and decadal time scales has been recognized as greater than commonly perceived with increasing impacts on ecosystems and available water resources. Changes in vegetation distribution, composition and productivity resulting from climate change affect plant water use, which in turn can alter stream flow, groundwater and eventually available water resources. To better understand these links, project researchers implemented two computer-based numeric models in the Cleve Creek watershed in the Schell Creek Range, east of Ely, Nevada. The application of the... Categories: Project; Types: Map Service, OGC WFS Layer, OGC WMS Layer, OGC WMS Service; Tags: 2013, CASC, Cleve Creek, Climate, Completed, All tags...

These saltmarshes, mudflats, and shallow bays are not only critical for wildlife, but they also provide economic and recreational benefits to local communities. Today, sea-level rise, more frequent and stronger storms, saltwater intrusion, and warming water temperatures are among the threats that are altering these important habitats. To support future planning and conservation of California’s near-shore habitats, researchers examined current weather patterns, elevations, tides, and sediments at these sites to see how they affect...

The disruptions it is causing require that we change the way we consider management in order to ensure the future of habitats, species, and human communities. Practitioners often struggle with how to identify and prioritize specific climate adaptation actions (CAAs). Management actions may have a higher probability of being successful if they are informed by available scientific knowledge and findings. The goal of the Available Science Assessment Process (ASAP) was to synthesize and evaluate the body of scientific knowledge on specific, on-the-ground CAAs to determine the conditions, timeframes, and geographic areas where particular CAAs...

Developing predictions of future conditions is often the first step in helping decision makers and communities plan for change. However, to date, available global climate models have been too coarse in resolution to be useful for planning in the context of small, isolated islands. This project produced the first-ever set of high-resolution climate projections for Guam and American Samoa, providing information...

These objectives were designed to address decision support needs for climate adaptation and resource management actions. Specifically, understanding of uncertainty in climate projections - in particular for extreme events - is currently a key scientific and management barrier to adaptation planning and vulnerability assessment. The new dataset fills in the Northwest domain to cover a key gap in the previous dataset, adds additional projections (both from other global climate models...

Recent changes in climate have caused winter flooding and warmer summer water temperatures in the region, reducing the cold-water habitats that bull trout depend on. The southernmost bull trout populations, found in Oregon, Washington, Idaho, Montana, and Nevada, are currently restricted to small reserves where the coldest waters still exist. These shrinking habitats have created a severed environment being further split by dams, poor water quality, and invasive species. The goal of this project was to determine how these factors threaten the species regionally by using predictions of stream...

Many federal, state and local agencies use stream insects to monitor the health of freshwater ecosystems. While the temperature ranges for some insects are often inferred from the temperature of the waters where they were collected, this inference is coarse at best and problematic at worst. Stream temperatures fluctuate a lot during the year and temperature may or may not control where an insect lives. Field insects were collected and sent to a laboratory for testing several temperature endpoints, particularly at higher temperatures. Respiration, breathing rate, and some physical activities were...

Reduced precipitation can also lead to lower water levels in streams and losses in the vegetation that grows alongside riverbanks. The goal of this project was to identify how hydrologic systems in the Southwest might respond to changes in climate and the degree to which this response is dependent on the characteristics of the hydrologic system. To do this, researchers developed a tool that simulates how quickly...

Over the past century, however, populations have dramatically declined due to habitat loss, overharvest, and invasive species. Consequently, many populations are listed as threatened or endangered under the U.S. Endangered Species Act. Complicating these stressors is global warming and associated climate change. Overall, aquatic ecosystems across the PNW are predicted to experience increasingly earlier snowmelt in the spring, reduced late spring and summer flows, increased winter flooding, warmer and drier summers, increased...

Aspen woodlands also provide high quality forage for livestock and draw tourists to the region to view the golden vistas that form in the fall. However, aspen is currently declining across large portions of the West and it’s estimated that approximately 40% of western aspen will be without suitable climate conditions within 50 years. In the northern and central Rocky Mountains, it’s thought that reduced...

These managers need state-of-the-art, scientifically based information upon which to base these management plans and decisions consistently across California and the Great Basin. This project applies historical, current, and projected climate data to a regional water model to examine water availability, biodiversity, and conservation. Analysis of this climate and hydrology data is expected to help managers understand areas in the region and landscape where the effects of climate change are expected to be the most profound.

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...
