Crossing the Idaho-Oregon border in winter
This remote area along the southern Idaho-Oregon border was affected by the 2015 Soda Fire, which burned nearly 400 square miles of sagebrush habitat important to many species of wildlife, as well as federal and private ranchlands.

Testing for Bsal
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

Setting up a bacterial control experiment on cheatgrass
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.

Experimental plot of native bunchgrasses at the site of the Soda Wildfire
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.

Close-up of biocrust - lichen
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.
