Programs L2 Landing Page

Scientists in the Environments Program conduct research on the various ecosystems that occur across 416 million acres of public lands in the United States and its territories. We conduct research on these natural systems to provide information to Department of Interior agencies, which they can use to make decisions about how to manage public lands and trust resources.

Ecosystem Management

Ecosystem Management

Our ecological research improves the Nation’s understanding of how management decisions and environmental variation are impacting ecosystems now and in the future.

Wildland Fire Research

Wildland Fire Research

Wildfires are a natural process in most regions of the U.S. They serve a vital role in nature but can also be unusually intense, widespread, or frequent. As a result, response and recovery costs are increasing.

Environments Science

USGS science provides tools and information to protect responders, communities, managers and species by identifying wildland fire risks, developing ways to reduce wildfire hazards, and assessing and minimizing the aftermath of wildfires.

News

Ecological research is largely concerned with the system levels beyond that of the organism. An ecological community is all the animal and plant populations occupying a given area. Research to understand ecosystem use by humans has led to the development of sub-disciplines such as sustainable development, resilience theory, restoration ecology, and ecosystem services.

Seeking the Seeps

From June 12 to July 3, 2019, the USGS is sailing onboard Schmidt Ocean Institute’s R/V Falkor with several other partners, seeking methane seeps along the seafloor of several underwater canyons off the coast of Oregon and Washington. On this cruise, USGS scientists will seek to understand how much methane is coming out of these seeps, how it travels through the water column, and its ultimate...

Assessing stream health and fish habitat in streams of the Chesapeake Bay Watershed

Streams and rivers provide habitat for a diverse array of aquatic and semi-aquatic species. However, human alteration to landscapes and riverscapes has affected this habitat resulting in its degradation and thus loss of habitat and associated sensitive aquatic species.  While this relationship has been known for many years, only recently has the availability of data and analytical capabilities...
