A team of biologists prepares to measure, weigh, and tag a captured bats. On the left, USGS biologist Gabe Reyes has a bat in a bag, used to separate and calm the bats. USGS biologist Julia Ersan is holding some alcohol used to ensure clean instruments and work surfaces, and USGS biologist Austin Waag is getting something out of a backpack.

A map of an area of the Minidoka National Wildlife Refuge that was burned by wildfire. Researchers conducted experiments testing the longevity of herbicides for controlling exotic annual grasses. The fire perimeter is displayed with a red outline. Stripes of tan were sprayed with indaziflam. Stripes of purple were treated with indaziflam and imazapic.

An experimental plot that was drill seeded with native grasses after the Martin Fire in northern Nevada. Drill seeding is a method in which a drill buries seeds into the soil at a targeted depth that is ideal for that plant species. A tractor typically pulls the drill along to bury the seeds in rows.
