USGS researchers preparing to plant cheatgrass seeds in an experimental plot near Boise, Idaho and look at the impact of temperature, planting density, and genetics on cheatgrass phenology. Holes are drilled in a grid to ensure cheatgrass seeds are planted with even spacing at the same depth. 25 seeds were planted per plot.

This bald eagle was admitted to The Raptor Center in St. Paul, MN where it was determined by veterinarians to be poisoned by lead. The bowed head, drooped wings, and green stained tail feathers are all typical signs of lead poisoning of raptors.

Locations of barred owl sightings recorded during 2015 owl monitoring activities. Barred owls were lethally removed from the areas highlighted in pink. Supporting data is found at https://doi.org/10.3133/ofr20201089.

Barred owls spread west during the 1900s and today completely overlap the range of the northern spotted owl.

USGS scientists setting up experimental plots in a previously burned site near Boise, Idaho. Fencing keeps livestock from disturbing the site. The experiment was replicated at a second site in Cheyenne, Wyoming. The team is looking at the impact of temperature, planting density, and genetics on the timing of the cheatgrass life cycle.

Two Columbian black-tailed deer are photographed by a trail camera on the former Mills reservoir by the Elwha River. Trail cameras are used to document wildlife recovery and use of this restored habitat post-dam removal.
