Western Bumblebee and Native Pollinator Research

The western bumblebee (Bombus occidentalis) occurs across western U.S. and Canada, and was one of the most common bumblebees in this region.  However, research suggests it has been declining, and the U.S. Fish and Wildlife Service will consider it for listing under the Endangered Species Act. Data are needed to improve our understanding of the resilience, redundancy, and representation of the...

Using Robots in the River: Biosurveillance at USGS streamgages

For more than a decade, researchers around the world have shown that sampling a water body and analyzing for eDNA is an effective method to detect an organism in the water. The challenge is that finding organisms that are not very abundant requires a lot of samples to locate this needle in a haystack.  Enter the "lab in a can", the water quality sampling and processing robot.

Estuaries and large river deltas in the Pacific Northwest

Essential habitat for wild salmon and other wildlife borders river deltas and estuaries in the Pacific Northwest. These estuaries also support industry, agriculture, and a large human population that’s expected to double by the year 2060, but each could suffer from more severe river floods, higher sea level, and storm surges caused by climate change.

USGS science supporting the Elwha River Restoration Project

The Elwha River Restoration Project...

... has reconnected the water, salmon, and sediment of a pristine river and coast of the Olympic Peninsula of Washington. Coordinated by the National Park Service, restoration of the Elwha River included the removal of two large dams that had blocked salmon and sediment passage for almost 100 years. The largest dam removal in U.S. history began in...

Sediment Transport in Coastal Environments

Our research goals are to provide the scientific information, knowledge, and tools required to ensure that decisions about land and resource use, management practices, and future development in the coastal zone and adjacent watersheds can be evaluated with a complete understanding of the probable effects on coastal ecosystems and communities, and a full assessment of their vulnerability to...

Coastal Habitats in Puget Sound

A Pacific Northwest icon, Puget Sound is the second-largest estuary in the United States. Its unique geology, climate, and nutrient-rich waters produce and sustain biologically productive coastal habitats. These same natural characteristics also contribute to a high quality of life that has led to growth in human population and urbanization. This growth has played a role in degrading the Sound...
