The red-cockaded woodpecker is a federally listed species that declined in the southeastern United States from approximately 1.6 million cooperative breeding groups to less than 3,500 groups due to loss and degradation of habitat and fire suppression.

This radio tagged Oregon spotted frog was photographed at Upper Klamath Marsh National Wildlife Refuge in Oregon. Radio telemetry tagging allows researchers to monitor the movements and distributions of species like frogs that are cryptic and often difficult to spot in the wild.

The turbid waters of the Elwha River and the coastal waters of the Strait of Juan de Fuca mix directly offshore of the river mouth, forming a large coastal plume.  This plume is easily identified by the cloudiness of the water (or "turbidity") resulting from sediment discharged by the river.  Two large dams on the Elwha River are being incrementally r

Barred owls (Strix varia) have expanded their geographic range from eastern to western North America. Their newly expanded range now completely overlaps that of the federally threatened northern spotted owl (S. occidentalis caurina).
