Waterbird Breeding Ecology and Management
The San Francisco Bay is designated as a site of hemispheric importance to shorebirds and annually supports over one million waterbirds. Within the USGS WERC waterbird breeding ecology program, Dr. Josh Ackerman and partners are studying habitat selection, movements, and factors influencing waterbird nest success and chick growth and survival.
Waterfowl Ecology in California and the Pacific Flyway
The Suisun Marsh and Central Valley in California offer some of the world’s most important wetland habitats for waterfowl in the Pacific Flyway. Mike Casazza and USGS WERC biologists are providing the science to support and evaluate waterfowl populations and habitat management in North America.
Wetland Restoration in the San Francisco Bay Delta and Pacific Northwest
Estuaries and healthy coastal habitats are among the most productive ecosystems on Earth. They provide a variety of benefits, including habitat and food for fish and wildlife, flood and erosion protection, improved water quality, increased carbon sequestration, as well as beautiful scenery and opportunities for recreation. Along the U.S. Pacific Coast, both the San Francisco Bay estuary and the...
Wildland Fire Science in Forests and Deserts
Fuel conditions and fire regimes in western forests and deserts have been altered due to past land management, biological invasions, and recent extreme weather events and climate shifts. These changes have created extreme fire risk to local and regional communities, threatening their economic health related to wildland recreation, forest production, livestock operations, and other uses of public...
Greater Sage-Grouse Population Ecology
Greater Sage-grouse are iconic birds found only in the Great Basin of the western U.S. Known for their showy courting displays, sage-grouse rely on native sagebrush habitat to shelter their young. Dr. Pete Coates is providing resource managers with the tools and information they need to conserve sage-grouse as invasive plants, evolving wildfire patterns, and energy development change the Great...
Stressors to Greater Sage-Grouse
The Greater Sage-grouse is a small bird found only in the sagebrush steppe of the Great Basin. Invasions of non-native grasses, evolving wildfire patterns, grazing from livestock, and human land uses are changing this unique ecosystem. WERC’s Dr. Pete Coates studies sage-grouse populations to determine how these influences could affect the bird and other wildlife in the future.
Reproductive Success of Black-Crowned Night-Herons and Snowy Egrets on Alcatraz Island
Years after the last inmate departed Alcatraz Island, waterbirds like Black-crowned Night Herons and Snowy Egrets still make the forbidding island their home. The National Park Service has requested the aid of WERC’s Dr. Pete Coates to inform efforts to expand visitor access to the Island, and simultaneously maintain healthy waterbird populations.
Behavior, Ecology, and Disease of Bobcats in Southern California
As cities and highways expand to support growing communities, USGS scientists are studying wildlife ecology to inform conservation efforts. Dr. Erin Boydston collaborates with the National Park Service, the U.S. Fish and Wildlife Service, and others to study the behaviors and disease ecology of bobcats and other carnivores in southern California. Explore this project’s “Science” tab to learn more...
Wildlife Connectivity in Human Environments
Today, urban development is rapidly fragmenting the open spaces of western North America. This can affect species that need large areas to roam, live at low densities, and tend to come into conflict with people. Dr. Erin Boydston studies the connectivity of wide-ranging mammals to inform long-term conservation planning in southern California. High levels of connectivity between wildlife...
Human Influence on Desert Tortoise Habitats
The deserts of the Southwest are under increasing pressure from growing human communities. The spread of cities, agricultural fields, grazing livestock, power plants, and other forms of human development in the past and present have affected the region’s natural resources, including its wildlife. WERC’s Dr. Kristin Berry is studying the response of threatened desert tortoises to changing habitats...
Food Web and Invertebrate Ecology Studies in Pacific Coast Estuaries
Invertebrate communities provide food for several economically and ecologically important fish and waterbird species in coastal estuaries. Scientists at the WERC San Francisco Bay Estuary Field Station specialize in studying foraging ecology of waterbirds and fishes, general food web dynamics across estuaries, and the effects of habitat restoration and other factors on waterbird prey availability.
Kelp Forest Community Ecology
The near shore waters along the coast of southern California host one of the most productive marine ecosystems on earth: giant kelp forests. These complex environments provide habitat, food, and hiding places for more than 1,000 species of plants and animals, but are easily disturbed by both natural events and human activities. Strong storms, fluctuating water temperatures, coastal development...
