Ecological Frontiers

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). 

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...

WARC researchers are working to quantify the impacts of future climate and land use/land cover change on greenhouse gas emissions and reductions.

To ensure successful restoration of coastal wetlands, WARC researchers will measure carbon cycling processes that indicate ecosystem health and sustainability.

Prairie Pothole Region wetlands provide numerous ecological services to society such as wildlife habitat, water storage, and carbon sequestration. Agricultural production in the region has been enhanced through the expanded installation and use of subsurface drainage systems, but these systems may have a negative impact on the region’s wetlands, including those protected by conservation easements...

Developing effective living shoreline restoration projects that can withstand hurricanes and storms requires a better understanding of how restoration structures reduce the impact of wave and current energy on marsh edges in estuaries and bays. Without this knowledge, existing living shoreline projects and adaptive management measures are more likely to fail, decreasing the possibility for long...

Barrier islands provide numerous invaluable ecosystem goods and services including storm protection and erosion control for the mainland, habitat for fish and wildlife, salinity regulation in estuaries, carbon sequestration in marshes, recreation, and tourism. These islands are dynamic environments due to their position at the land-sea interface. Storms, wave energy, tides, currents, and relative...
