Restoration Ecology and Species Recovery

The WFRC conducts research that elucidates how landscape level stressors like climate, land use, and water availability affect culturally, ecologically, and economically important species and ecosystems. This information is vital for informing decisions involved with restoration ecology and species recovery, by increasing the effectiveness of restoration programs.

Southwestern Willow Flycatcher Habitat Viewer

For planning and management purposes, agencies require a web application that can locate, map, and monitor Southwestern Willow Flycatcher (flycatcher) breeding habitat across its range. The Habitat Viewer can identify potential flycatcher habitat and monitor changes caused by stressors, such as beetles, fire or drought.

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.

Life History of Pacific Northwest Fishes through Age and Growth Structures

The focus of our research is the ecological analysis of Pacific Northwest fishes through age and growth structures such as: scales, fin rays and otoliths (small calcium carbonate deposits beneath the brain used in hearing and balance that grow in proportion to the overall growth of the fish). These structures are utilized as research tools for understanding life histories and habitat importance...

Salmonid Population and Life History Research in Tributary Stream and River Habitats and Response to Dam Removal

Juvenile anadromous salmonids all spend some portion of their lives in freshwater. This time may vary from days to years depending upon species and run. Spring Chinook Salmon and Coho salmon generally spend one year in freshwater and Steelhead may spend up to five years in freshwater prior to beginning their journey to sea. Several projects at WFRC – CRRL are investigating populations, life...

Columbia River Basin Sturgeon Habitat Modeling

A study was conducted to identify habitat characteristics associated with age 0 White Sturgeon (Acipenser transmontanus Richardson, 1863) recruitment in three reaches of the Columbia River Basin: Skamania reach (consistent recruitment), John Day reach (intermittent/inconsistent recruitment), and Kootenai reach (no recruitment).

Contaminants in Puget Sound Forage Fishes and Impacts to the Marine Food Web

Toxic chemical pollutants have been released into Puget Sound for decades by human activities. There’s a wide range of contaminants, from persistent compounds like polychlorinated biphenyls (PCBs) and flame retardants to contaminants of emerging concern. Aquatic species can be exposed to and accumulate contaminants, causing disease or disruption of biological processes like growth or reproduction...

Scientific Support of Salmon and Steelhead Reintroductions in Impounded River Basins of the Pacific Northwest

Salmon and steelhead populations in the Pacific Northwest were severely affected by hydropower development that occurred during the first half of the 20th century. Impassable dams were constructed on many rivers throughout the region which prevented returning adult salmonids from accessing important habitats where spawning and rearing historically occurred. In the past two decades resource...
