A Berlese-Tullgren funnel system that is used for studying soil invertebrates. This laboratory technique causes soil invertebrates to move away from the soil surface as it is being warmed and dried by the lights above. The invertebrates are caught in jars of ethanol below the funnels, counted, and identified under a microscope.

The Snake River is the largest tributary of the Columbia River. It drains over 108,000 square miles in mainly Idaho and portions of Montana, Nevada, Oregon, Washington, and Wyoming. The climate of much of the Snake River watershed is arid or semi-arid and spring snowmelt contributes substantially to the river’s flow.

Western purple martins require abundant snags for nesting. Retaining snags after timber harvest is one solution to help this declining species recover.

The sagebrush steppe of the western U.S., including the site of the 2015 Soda Wildfire pictured here, is vast and encompasses landscapes with variable elevation, weather, water availability, aspect, soil type, and more.

This image taken at the site of the 2015 Soda Wildfire shows the effect of aspect on plant communities in the sagebrush steppe. Aspect refers to the direction in which a landform, like these hills, is oriented in relation to the sun's path across the sky.
