Working with Partners

Tires contain a chemical known as 6PPD which prevents them from quickly breaking down. Microscopic tire particles, generated mainly from the friction of tires on roads, release 6PPD-quinone (6PPDQ) when they come into contact with oxygen. During precipitation events, 6PPDQ can be washed off roads, harming fish in nearby waterways. In response to requests from fishery managers, the USGS is studying...

This study provides a comprehensive assessment of the health of streams throughout the Chesapeake Bay. Monitoring data were used to assess seven key indicators of stream condition, revealing consistent patterns of degradation in urban and agricultural areas. The findings offer critical insights that can inform watershed restoration efforts and improve long-term monitoring strategies.

Ongoing global outbreaks demonstrate the capacity of highly pathogenic avian influenza virus (HPAIV) to impact poultry, wild birds, and even human health. USGS research is advancing the understanding of the spatial and temporal interface between wild and domestic bird populations from which these viruses emerge to aid biosecurity planning and outbreak response.

A recent study provides key considerations about modeling the timeline of tidal marsh longevity. These timelines can help resource managers envision what future marsh conditions may look like, informing current and long-term adaptive management strategies.

The Chesapeake Bay provides over $100 billion in annual economic value and is home to 18 million people. The USGS, including scientists from the Eastern Ecological Science Center (EESC), works with Federal, State, local, and academic partners to provide research and monitoring and to communicate results to inform management for the Chesapeake and other important landscapes across the Nation.

As a data-driven bureau, the USGS Ecosystem Mission Area (EMA) relies on artificial intelligence (AI) to efficiently gather, analyze, and deliver natural resource information to Federal, State, Tribal, academic, and industry partners. USGS EMA scientists are developing and testing innovative uses of AI, including machine learning, deep neural network models, and photogrammetry, to streamline the...

USGS researchers are collaborating with partners around the globe to leverage new and existing telemetry data to answer broad scale questions about factors influencing avian movement and migration.

USGS researchers seek to understand the factors influencing the spread and persistence of avian influenza viruses on the landscape. This research also addresses how novel strains of highly pathogenic avian influenza are impacting a larger number and diversity of host species, including waterfowl, shorebirds, raptors and other birds.

USGS researchers are at the forefront of building and maintaining datasets that represent the spatial and temporal patterns in avian influenza virus prevalence in wild birds, which is critical information used to estimate transmission risk to domestic poultry.

USGS researchers are developing novel methods to improve our understanding of waterfowl distributions and abundance across the United States to inform a variety of ongoing disease studies. Understanding the distribution of wild waterfowl is a critical component to assessing avian influenza transmission risks across the landscape.

Human activities in the Chesapeake Bay watershed can negatively affect the abundance and diversity of macroinvertebrate communities in freshwater streams, which is a core measure of stream health. For example, urban development and agricultural intensification can degrade habitat and water-quality conditions in streams through sedimentation, nutrient runoff, and changes to instream habitat. A...

Through collaboration and coordination, USGS research helps preserve and restore America’s most iconic landscapes. We apply insights across ecosystems to understand how these systems function and change, helping natural resource managers protect our Nation’s natural heritage for generations to come.
