Ecological Frontiers

USGS is working with federal, state and local partners to develop multiple assessments of stream and river conditions in non-tidal areas of the Chesapeake Bay watershed. These assessments will help managers preserve stream health and improve biological conditions in impaired streams as the human population and climate continue to change in this region.

Coastal ecosystems provide critical local and national societal benefits such as coastal protection and fish nurseries but are some of the most heavily used and threatened systems on the planet. The Mangrove Science Network is a collaboration of USGS scientists focused on working with natural resource managers to develop and conduct mangrove research.

Tree-ring science is a component of our interdisciplinary ecological research program that focuses on the effects of climate variability and human land use on forest ecology, fire ecology, and ecohydrology.

Habitat models can provide critical information on the current and potential distribution of plant species, as well as help target and support conservation efforts. Despite their potential utility in public land management, model use may be constrained by a variety of factors including staff access to and trust in models. In this project, we seek to bring together model users and model developers...

Land managers require clear, forward-looking information about where and how vegetation treatments may make the greatest difference for drought resilience in sagebrush and woodland ecosystems. We are using soil moisture and vegetation data from SageSTEP-- a long-term ecological study on fuel treatments in the Great Basin-- to analyze soil moisture dynamics and vegetation responses after common...

Management partners have identified a major need to understand the short and long-term consequences of altered wildfire patterns, vegetation change, climate change, and management actions for the carbon cycle. This project aims to quantify carbon storage and greenhouse gas emissions in sagebrush rangelands. Researchers will link findings to the Sagebrush Conservation Design Framework and provide...

The Mangrove Science Network is a collaboration of USGS scientists focused on working with natural resource managers to develop and conduct research whose findings will support and evaluate decisions made in mangrove management and restoration.

Forests are a key component of a healthy ecosystem. Management of these resources is vital to their protection as a recreational resource as well as an environmental resource.

Mountain ecosystems are highly sensitive to climate change, and USGS is conducting montane research across the West to help resource managers plan now for the future. Coordination with scientists around the world has led to mountain research networks to expand our understanding of how these ecosystems respond to climate change.

America’s grasslands are in the middle of the country where there is insufficient rain to support forests but too much to be a desert.

Managing the world’s freshwater ecosystems including lakes, rivers, and springs, and the water they supply to meet environmental and societal needs in a changing climate is one of the biggest challenges for the 21st century.

In the United States, three “hot deserts” receive precipitation in the summer months (Mojave, Sonoran, Chihuahuan) and one “cold desert” receives precipitation in the winter (Great Basin).
