Remnants of a spruce forest
Remnants of a spruce forest complex following a severe wildfire in the Yukon Flats National Wildlife Refuge, Alaska. Wildfires are the dominant landscape-scale disturbance operating at annual time scales in Alaska, and fires play a major role in the rate and extent of vegetation growth and productivity of a site.

A meltwater stonefly larva (Lednia tumana)
A meltwater stonefly larva (Lednia tumana) sits on a cobbled snow fed stream in Glacier National Park. The species is threatened by climate warming induced glacier and snow loss and has been petitioned for protection under the U.S. Endangered Species Act due to climate-change-induced habitat loss.

WRP St. Landry Parish, Louisiana
Wetlands Reserve Program site in St. Landry Parish, Louisiana. Changes in a local river resulted in the landowner’s fields flooding on a regular basis. The landowner worked through the USDA Natural Resources Conservation Service to restore his fields to their natural wetland state.
