Scientists sample a rough-skinned newt for the fungal pathogen Batrachochytrium salamandrivorans, or Bsal, at a pond near Portland, Oregon. Bsal is decimating wild salamander populations in Europe and could emerge in the U.S. thro

The eagle in the foreground with the wide white tail band is a golden eagle. The other eagles are two adult and one Basic II bald eagles.

Scientists are studying several weed suppressive bacteria to see if they can be used as a biological control on invasive exotic grasses, such as cheatgrass.

The Altamont Pass Wind Far is located in northern California.

Grass seeds on freshly burned soil at the site of the 2015 Soda Wildfire. Grass seeds were aerially sown to restore native perennial vegetation.

A plot of bunchgrasses that established after the 2015 Soda Wildfire. The site was treated with herbicide the first fall post-fire, then grasses were drill seeded the subsequent year. A fence was installed to exclude livestock. This approach of combining herbicide, seeding, and grazing treatments is known as layering.

Biologists snorkel the Bogachiel River in Washington State to count resident and migratory fish as part of a riverscape survey.

To investigate whether insects could be used as bioindicators of climate change, USGS researchers studied insect community composition along an elevation gradient in semi-arid shrublands of eastern Oregon.

A snag - or dead tree- remaining after timber harvest on BLM land in Eugene, OR. The western purple martin, a declining songbird species, depends on snags for nesting.

Biological soil crusts, or biocrusts, are lichens, mosses, and cyanobacteria that grow on the soil surface and are common in the spaces between native plants in arid and semi-arid systems. Biocrusts reduce soil erosion, contribute to nutrient and water cycling, and reduce evaporation and invasion by exotic plants.

The 2016 SageSTEP field crew.  They are collecting vegetation monitoring data at SageSTEP's (Sagebrush Steppe Treatment Evaluation Project) Moses Coulee site.  SageSTEP is a regional experiment evaluating methods of sagebrush steppe restoration in the Great Basin.

USGS researchers Brome McCreary (orange vest) and Chris Pearl take measurements on Cascades frog at a mountain lake in Oregon.

Anna Ormiston and Jesi Hessong, student contractors with the USGS Amphibian Research and Monitoring Initiative, or ARMI, display several discarded mylar balloon collected by field teams working in and around the Capital Region National Parks in the summer of 2015. They collected a total of 71 balloons.

USGS scientists monitor BLM efforts to restore vegetation in the area burned byt he 2015 Soda Fire in southwest Idaho and southeast Oregon sagebrush-steppe.

Determining aboveground biomass of sagebrush, grasses, and forbs is important for estimating fuel loads, measuring carbon storage, and assessing habitat quality in shrublands. Remote sensing may offer a more efficient alternative to common, labor intensive methods of measuring aboveground biomass that are difficult to apply across large areas.

Samples from various aquatic species and other material necessary to create environemntal DNA (eDNA) assays are stored at the Snake River Field Station in Boise. Water samples from aquatic ecosystems are compared against the assays to identify the presence and location of species in those ecosystems.
