The USGS Ecosystems Mission Area provides science to help America achieve sustainable management and conservation of biological and ecological resources in wild and urban spaces.

Climate change has and is projected to continue to alter historic regimes of temperature, precipitation, and hydrology.

Lakes in Wisconsin are getting warmer, and fish communities are changing as a result. Understanding recent trends and anticipating future changes can help decision-makers protect resilient populations, adapt to new conditions, and effectively communicate realistic expectations.

A geonarrative highlighting the Climate Adaptation Science Center's science, partnerships, and capacity building activities from Fiscal Year 2021.

USGS, as part of the National Wastewater Surveillance System, designed and implemented high-frequency sampling of wastewater across six states throughout September 2021, to support tracking of potential increases in COVID-19 infections in communities. COVID-19 viral loads were determined for each sample with the goal of delivering results to the CDC within three days of sampling.

The USGS provides information and tools needed to help solve problems posed by invasive species across the country. Key components of USGS invasive species science include developing novel prevention, forecasting, early detection, decision support, and control tools.

The Arctic Rivers Project will weave together Indigenous knowledges, monitoring, and the modeling of climate, rivers (flows, temperature, ice), and fish to improve understanding of how Arctic rivers, ice transportation corridors, fish, and communities might be impacted by and adapt to climate change.

Inland fisheries represent 12% of total global fishery production, provide accessible and affordable high-quality protein to some of the world's most vulnerable populations, and lack the traditional assessment processes necessary for estimating harvest potential. This project aimed to develop a scalable framework to assess the current and future status of inland fisheries worldwide.

The USGS, the science bureau of the Department of the Interior, conducts wildlife disease surveillance and research to support management of affected species and their habitats. Here you will find information on USGS science addressing Chronic Wasting Disease across the Nation.

California's Channel Islands were once home to cloud forests, but this unique ecosystem was lost. USGS & partners are bringing them back.

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.

Findings from US Geological Survey studies on sources, occurrence, effects and risk of contaminants throughout the Chesapeake Bay Watershed.
