The Nonindigenous Aquatic Species Flood and Storm Tracker (FaST)
Storm-related flooding can lead to the potential spread of nonindigenous (or non-native) aquatic species into waterways they have not been seen in before. The USGS Nonindigenous Aquatic Species program has developed an innovative mapping tool to help natural resource managers with post-storm nonindigenous aquatic species detection and assessment efforts.
Erosion of a Sea Stack Over 100 Years
The following photographs show the demise of Jump-Off Joe, a one-hundred-foot-high sandstone formation known as a “sea stack”. In 1890, the sea stack was composed of middle Miocene concretionary sandstone of the Astoria Formation. Yaquina Head on the Horizon is composed of middle Miocene basalt flows and breccia. Note remnant of Pleistocene terrace deposit along the wave cut bench on the stack...

WFRC Ecology Section - Projects Overview
The Ecology Section examines how environmental variability, human activities and infrastructure influence food web interactions and species performance in freshwater and marine ecosystems. We have extensive experience in quantifying aquatic food web processes as they relate to growth, survival and production of key species of interest, especially resident and anadromous salmonids.

Columbia torrent salamander (Rhyacotriton kezeri)
Torrent salamanders are Northwest-U.S. endemic, headwater-stream-associated amphibian species that have a dearth of basic ecological information, but are thought to be highly vulnerable to habitat changes. This taxon currently has two candidates for listing by the Endangered Species Act: the Cascade torrent salamander (Rhyacotriton cascadae) and the Columbia

Tribal Resources for Climate Change Vulnerability Assessments
Tribes have been actively engaged in efforts to anticipate and respond to climate impacts on their natural and cultural resources. And yet, some tribes have faced difficulties initiating and completing the critical first step of the climate adaptation planning process: an assessment of locally-specific climate risks that accounts for the unique priorities, values, and

Rear-arc basalt lava outcrop
A 3-4m (10-12 ft) high outcrop of basalt lava, part of a broader lava flow. These flows were erupted about 300,000 years ago following basalt dike intrusions in a rear-arc region of northern California. The eruptions of three of these flows are thought to have taken place within several hundred years of each other.

Alder root nodules
Root nodules are a symbiotic relationship between a plant and nitrogen-fixing bacteria. A symbiotic relationship is one where both organisms benefit. Nitrogen-fixing bacteria change inorganic nitrogen from the air into ammonia, a form of nitrogen most organisms can use. They also use a process called rock dissolution to release other nutrients, such as calcium and

Starting in 2011, the National Park Service removed two obsolete dams from the Elwha River in Olympic National Park, Washington. It was the world’s largest dam-removal project. Over the next five years, water carrying newly freed rocks, sand, silt and old tree trunks reshaped more than 13 miles of river and built a larger delta into the Pacific Ocean.
The atypical location of Mount St. Helens may be due to geologic structures that control where deep magmas can rise through the crust, as suggested by new findings published today in Nature Geoscience.
