Assessing the severity of the Funny River fire on the Kenai Peninsula
Pre- and post-fire measurements of fire effects help ecologists, fire scientists, and managers determine how the severity of wildfires affects plants, animal habitat, and ecosystem services.

Reburns are becoming more common in many parts of Alaska
Reburns, or fires that burn more frequently than expected, are becoming more common in Alaska and can cause major changes in vegetation composition, wildlife habitat, and landscape resilience

Biologists Collecting Biological Samples from Grizzly Bear
USGS biologists collecting biological information from a grizzly bear they have captured. Biologists collect hair samples for genetic analysis, weigh the bear, and gather numerous measurements of the body, such as the head, paws, claws, teeth, etc. Overall condition of the bear is assessed as well, including a body fat measurement.

Piping Plover Nest
USGS scientists are working to model shorebird habitat availability both today and in the future, given processes like sea-level rise, in an effort to support the efficient management of beaches for both people and nesting shorebirds.

Douglas-fir trees topped to create snags for wildlife habitat
Snags provide habitat for a wide range of organisms from cavity-nesting birds to insects, and are critical for maintaining forest biodiversity. Resource managers can create snags by topping trees to mitigate loss of snags to timber harvest, but information regarding changes in habitat for snag-dependent wildlife over time as created snags decay is lacking.
