Three of the nine wild sea otter populations in the U.S. are federally listed as threatened. In California, USGS biologists have lead an annual population census to assess the local populations' recovery, working closely with state agencies and the Monterey Bay Aquarium.

Don Ashton uses radio telemetry to track a federally threatened Oregon spotted frog (Rana pretiosa). Data provide information on resource use, movement patterns, and overwintering

USGS scientists created outdoor testing plots where large squares of biocrusts were exposed to different warming and precipitation factors over time.

USGS scientist Sasha Reed studies sites where different climate conditions are being mimicked to determine effect on biocrusts.
