Science and Products
San Francisco Bay
USGS scientists have made great strides in refining and extending the capabilities of the Computational Assessments of Scenarios of Change for the Delta Ecosystem (CASCaDE II model systems); a collaboration among the USGS and several academic and international organizations. This paved the way for more reliable and objective evaluations of the ecosystem consequences of management actions and...
River Environments
Protecting endangered species while managing economically important species is an ongoing natural
resource management challenge, especially in rivers. The USGS develops tools like biological/economic models to identify optimal strategies and economic and biological tradeoffs when adding nonnative species to rivers where endangered native species exist. This ongoing research will provide...
Montane Environments
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.
Mangrove Science Network
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 research on mangrove ecosystem biology includes mangrove regeneration, tree growth, sedimentation, and early seedling development. We are...
Forests
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.
Ecosystem Ecology
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. The community (biotic) and the nonliving environment function (abiotic) together as an ecological system or “ecosystem” which is governed by principles such as population dynamics, competition, and energy and...
Decision Analysis
USGS scientists work with decision makers and stakeholders to develop decision analytic frameworks to deliberately reduce the uncertainty that negatively affects the quality of decisions whether made once (i.e., Structured Decision Making) or repeatedly (i.e., Adaptive Management).
Forecasting
Informed forecasting of landscape structure, function, composition, and condition requires an understanding of the factors that control, constrain, and regulate ecosystem dynamics. USGS science is focused on understanding these driving factors using ecological research, long-term field studies and ecosystem modeling. Additionally, the USGS works with partners to provide alternative strategies...
System Understanding
The Environments Program responds to the needs and requirements of resource management bureaus within the Interior and other science and resource management organizations by designing, developing and conducting research required for the resource management and policy decisions made by a variety of stakeholders.
Overcoming challenges to the recovery of declining amphibian populations in the United States
The US Endangered Species Act of 1973 (ESA) affords many potential benefits to species threatened with extinction. However, most at-risk amphibians—one of the most imperiled vertebrate groups—remain unlisted under the provisions of the ESA, and many impediments to recovery exist for those species that have been listed. Of the 35 US amphibian...

Mangrove postcard
Mangrove ecosystems protect vulnerable coastlines from storm effects, recycle nutrients, stabilize shorelines, improve water quality, and provide habitat for commercial and recreational fish species as well as for threatened and endangered wildlife. U.S. Geological Survey scientists conduct research on mangrove ecosystems to provide reliable...

Wetlands postcard
Wetlands Postcard Research conducted by scientists at the U.S. Geological Survey provides reliable scientific information for the management of wetlands ranging from small freshwater alpine lakes in the Western United States to coastal wetlands of the Great Lakes and salt marshes along the Southeastern coast.

Ball, Lianne C. An adaptive decision framework for the conservation of a threatened plant
Mead's milkweed Asclepias meadii, a long-lived perennial herb of tallgrass prairie and glade communities of the central United States, is a species designated as threatened under the U.S. Endangered Species Act. Challenges to its successful management include the facts that much about its life history is unknown, its age at reproductive maturity...
