Starting in 2017, U.S. Geological Survey (USGS) researchers and land managers are co-producing a network of restoration field trial sites on Department of Interior (DOI) and surrounding lands in the southwestern U.S. The network systematically tests restoration treatments across a broad range of landscape, soil, and climate conditions.

Non-lead ammunition, such as those made from copper, tend to remain intact after impact with their target, while lead ammunition can fragment into many small pieces.

USGS map showing the movement of a lesser scaup infected with highly pathogenic avian influenza (red line) compared to four lesser scaup not infected (maroon, yellow, blue and black lines). Movement was recorded January 23 to 26, 2022. The black dot identifies where the birds were captured and released in Maryland.

USGS scientist Jeff Pigati collects pollen for radiocarbon dating at the site where human footprints were found in order to estimate the age of the footprints. Pollen also provides a picture of what kind of vegetation existed at the time that the footprints were made.

The USGS Ecosystems Mission Area (EMA) is encouraging participatory science with its partners. EMA is a leader in participatory science activities and this guidance emphasizes support for this research design model that encourages research projects, as appropriate, to engage in enhanced forms of participatory science.

Argentine black and white tegus (Salvator merianae) can survive the winter under semi-natural conditions well beyond their current invasive range.

Mesopredators play important ecological roles in most systems. This group of wildlife is often well-adapted to human development and their densities can vary according to the human-subsidized resources with trickle down effects on other animals.
