White-nose syndrome has been detected in Washington. USGS scientist are helping the NPS design and evaluate bat sampling protocols for their Pacific Northwest parks.

A remnant beaver pond that was excavated and deepened to provide aquatic habitat for amphibians including the Oregon spotted frog. Five years post-construction, the excavation project has resulted in more consistent water retention during drought in the Klamath Basin.

Two adult bald eagles look on while two younger bald eagles fight. The eagle on top is a juvenile bald eagle and the one on the bottom is a Basic IV.

This adult female bald eagle is named "Relish." She was banded #57 and fitted with a GPS transmitter in January 2019 as part of the Raptor View Research Institute's bird-lead study. She nested near the Great Slave Lake in the NW Territories, Canada in the Summer of 2019. Her transmitter stopped sending location data in May 2020.

Great Basin rattlesnake (Crotalus oreganus lutosus) held by snake tongs. The Great Basin rattlesnake is the only venomous snake in Idaho.

Boise State University Master’s student Kristina Parker uses a syringe to collect blood from a Great Basin rattlesnake (Crotalus oreganus lutosus). The blood’s ribonucleic acid, or RNA will be analyzed to track genetic change in the snake from habitat disturbances. RNA, along with deoxyribonucleic acid – or DNA, are the molecules that carry genetic information.

Boise State University Master’s student Kristina Parker carries a Great Basin rattlesnake (Crotalus oreganus lutosus). The snake’s head is enclosed in a plastic tube to allow her to safely handle it during the biological sample collection process.

A Great Basin rattlesnake (Crotalus oreganus lutosus) is coaxed into a plastic tube. This plastic tube allows researchers to safely handle the rattlesnake during biological sample collection.
