Ecosystems We Research

Wildlife management boundaries frequently lack biological context, such as information on habitat resource availability and wildlife movements. To address this, we developed multiple levels of biologically relevant and hierarchically nested greater sage-grouse ( Centrocercus urophasianus) population units that could facilitate management and conservation of populations and habitats.

Researchers from the U.S. Geological Survey, the U.S. Department of Agriculture-Agricultural Research Service, and University of Arizona are studying the distribution of grassland bird communities across the western Great Plains to anticipate how species distributions may respond to a changing landscape.

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.

USGS researchers will utilize long-term soil elevation change data to help advance understanding of soil elevation dynamics and ecological transformations within coastal wetlands of the Greater Everglades.

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.

USGS economists and social scientists conduct economic and social science research in the context of natural resource management to deliver information used by resource managers to maximize and sustain economic and social benefits from natural resources to the American public.

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...

Starting in 2017, U.S. Geological Survey (USGS) researchers and land managers are co-producing a network of restoration field trial sites on Department of Interior (DOI) and surrounding lands in the southwestern U.S. The network systematically tests restoration treatments across a broad range of environmental gradients. Each site in the network is used to test suitable seed mixes and treatments...
