Coastal ecosystems are where the land and sea meet. USGS coastal science plays a critical role in supporting effective, science-based management of coastal ecosystems. USGS helps decision-makers navigate complex ecosystem challenges.

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.

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.

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). 

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.

Alaska is simultaneously a landscape of extremes requiring specialized adaptations by plants and animals to survive the winters and a landscape of abundance that supports breeding birds each summer from as far away as Africa. Terrestrial Alaska also supports iconic species such as caribou and muskoxen whose population dynamics, predator/prey relationships and habitat ecology are researched by USGS...

The San Francisco Bay-Delta PES is one way that USGS continues to provide science for the restoration and conservation of the SF Bay and its watershed. USGS research topics range from wetland restoration in the Bay to restoring habitat for anadromous fish (e.g., salmon) in the uplands. USGS has made several important discoveries critical to the fundamental understanding of this system and...

USGS scientists in the Gulf of America region conduct research that investigate the past, present and future trajectories of coastal ecosystems, the stressors that impact those ecosystems, and restoration and management alternatives that aim to recover and sustain ecosystem functions and services. Our researchers are engaged in restoration programs across the Gulf, including those spurred after...

The Platte PES focuses on restoration of the Central Platte river in Nebraska which has been designated as Critical Habitat for the survival and recovery of the Endangered whooping crane. USGS conducts research which informs the rehabilitation of the structure and function of habitat used by whooping cranes. The Platte PES is an element within the larger Midcontinent Migration Connectivity...
