Field technicians Marcus Rehrman and Maddie Zickgraf surveying for Oregon spotted frogs in Deschutes County, OR. Field survey data helps researchers keep tabs on the status of this threatened species.

Researchers at the Pacific Northwest Environmental DNA Laboratory designed artificial flowers to attract pollinators. DNA left behind on the flowers can be collected and analyzed as a non-invasive way to survey for pollinator species diversity and abundance.

Power lines run along a dirt track through the Morley Nelson Snake River Birds of Prey National Conservation Area in southern Idaho. Power poles are often the tallest structures available for bird perching and nesting in flat landscapes without trees.

While surveying for Oregon spotted frog egg masses in Deschutes County, OR, field technicians caught an adult female using a dip net. This was the first individual observed during the Spring field season.

Malheur Lake, a saline lake in eastern Oregon, photographed from a USGS airboat. USGS has been monitoring water quality parameters including temperature, turbidity, and pH in the lake since 2017.

A bald eagle and common raven found dead near the base of a power pole during a survey. Both birds were determined to have died from gunshot.

Experimental plots near Boise, Idaho after planting is complete. Black gravel increases the amount of sunlight absorbed by the ground, increasing the temperature of the plot. White gravel absorbs less light, keeping the plot cooler. Wooden toothpicks mark the location of cheatgrass seeds.
