Avian Influenza: Research by the USGS and Partners Avian Influenza: Research by the USGS and Partners

The USGS Ecosystems Mission Area provides science to understand wildlife diseases, including avian influenza (AI). Avian influenza viruses occur naturally in wild birds such as ducks, geese, swans, and gulls. These viruses generally do not cause illness in wild birds but they can be highly pathogenic and cause illness and death in poultry and wildlife. Learn more with this geonarrative.

Conservation Planning Tool for the Bi-State Distinct Population Segment of Greater Sage-grouse 1.0.0 Conservation Planning Tool for the Bi-State Distinct Population Segment of Greater Sage-grouse 1.0.0

A decision support tool for conifer treatment to restore greater sage-grouse ( Centrocercus urophasianus) habitat within the Bi-State, California and Nevada, area. This tool provides a science-based approach for prioritizing pinyon and juniper removal to improve habitat for greater sage-grouse in the Bi-State Distinct Population Segment.

Habitat Vulnerability Assessment for Wintering American Black Ducks Habitat Vulnerability Assessment for Wintering American Black Ducks

We estimated food availability among five main wetland cover types used by overwintering American Black Ducks: subtidal, fresh water, high marsh, low marsh, and mudflat. Bioenergetics models used to inform North American Waterfowl Management Plan (NAWMP) can be simplified into two major components: energetic demand and energetic supply.
