Modeling Songbird Density-Habitat Relationships to Predict Population Responses to Environmental Change Within Pinyon-juniper and Sagebrush Ecosystems
Within areas of overlapping sagebrush and pinyon-juniper ecosystems, wildlife populations are declining due to habitat fragmentation and degradation, changing climate, and human development. However, management to bolster species associated with one ecosystem may result in negative consequences for species associated with the other. Thus, land managers are challenged with balancing which system to...
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.
Informing seed transfer guidelines and native plant materials development: Research supporting restoration across the Colorado Plateau and beyond
As restoration needs for natural landscapes grow due to higher frequency and/or intensity disturbances, pressure from invasive species, and impacts resulting from changing climates, considerable time and resources are being invested to guide the development and deployment of native plant materials (NPMs). Across lower elevations of the Colorado Plateau, a region composed primarily of public land...
Grand Canyon Monitoring and Research Projects
The Grand Canyon Monitoring and Research Center currently functions under a Triennial Work Plan (TWP) which is thoroughly reviewed and vetted both internally within the Center and through the GCDAMP Technical Work Group (TWG) and the Adaptive Management Work Group (AMWG). These advisory panels have been a part of the Glen Canyon Dam adaptive management process since the inception of the GCDAMP...
Social and Economic Analyses
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.
Ecosystems We Study: Grasslands
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.
Ecosystems We Study: Freshwater Systems
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.
Ecosystems We Study: Alaska Bioregions and Arctic
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...
Lake Superior Beach Nourishment and Near-Shore Bathymetric Surveys of Minnesota Point at Duluth, Minnesota
The shoreline, beaches, and infrastructure in Duluth, Minnesota have been degraded along the Minnesota Point barrier island because of high water levels and heavy wave action. The U.S. Army Corps of Engineers (USACE) is exploring the beneficial use of dredge material for beach nourishment on the Lake Superior side of the barrier island.
Lake Powell Research
Lake Powell is a large arid reservoir that represents about 70% of the water storage capacity for the Upper Colorado River Basin. It is the second largest reservoir in the United States by capacity (second only to Lake Mead). Lake Powell is an oligotrophic reservoir, which means that nutrient concentrations and algal production are generally low. This often results in very clear-water conditions...
Ecological Modeling in Support of the Lake Okeechobee Water Management
The Joint Ecosystem Modeling team will be running a suite of ecological models to evaluate scenarios and provide insight into how alternative restorations plans compare, indicate whether alternatives could lead to unintended consequences, and determine effects of alternatives that could conflict with other goals.
Mapping Avian Habitat for the Gulf Coast Joint Venture
The Gulf Coast Joint Venture (GCJV) was established in 1988 as a result of the North American Waterfowl Management Plan, which espouses the restoration of continental waterfowl populations through conservation partnerships in priority habitat regions. Since that time GCJV partners have expanded their mission and purpose to include the provision of habitat to support other priority bird species...
