Map showing federal, state, and private land holdings of core winter elk range around the National Elk Refuge (labeled as the FWS unit). Map was generated by the USGS. 

Jackson elk herd migrations around the National Elk Refuge are shown in dark blue (short-distant migrants) and light blue (long-distant migrants). Elk migrations cross federal, state, and public lands. The map was generated by the USGS using data from the USGS Data Release Kauffman and others, 2020.

SPOOKY SCIENCE (and having some fun with a playful, silly, not real science career)

The northern rubber boa is an example of a species predicted to have a smaller climate-niche space by the end of the century. Under climate scenario RCP 8.5--which assumes carbon emissions stay near current levels--this species' range could be reduced from most of the northwestern U.S. to only a small portion of British Columbia.

A USGS scientist uses the grid-point intercept method to characterize plant communities in Larimer County, Colorado. The grid-point intercept method uses points along a grid to sample plant species or ground cover within a larger plot.

USGS scientists identifying plant community composition in Larimer County, Colorado. Information on plant community composition is critical for understanding differences in soil carbon-responses to exotic annual grass invasion between sites. 

USGS scientists dig small ‘micro pits' to collect soil for testing. The team is careful to minimize the impact to the environment. Soil is stored on a tarp while sampling so it can be returned to the pit afterwards.

A USGS scientist prepares a mini-disc infiltrometer to assess soil water infiltration. The degree to which water can infiltrate soil is closely tied to soil carbon content.
