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...
Developing Monitoring Programs for Damaged Ecosystems
California’s Channel Islands are recovering from a long history of ranching. As the island ecosystems respond to the absence of livestock, WERC’s Dr. Kathryn McEachern is working with the National Park Service to test new monitoring programs that could help ecologists and biologists study recovering environments across the West.
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.
Ecological Drought in Riparian Ecosystems
Drought is killing riparian trees along many rivers in the western United States. The cause can be increasing temperature or decreasing precipitation, flow or water-table elevation. At multiple locations we are relating water availability to physiological measurements of tree survival and water stress, such as ring width, carbon stable isotope ratio and branch hydraulic conductivity. These...
Ecohydrology and Climate Change in Drylands
Drylands cover 40% of the global terrestrial surface and provide important ecosystem services. However, climate forecasts in most dryland regions, especially the southwest U.S., call for increasing aridity. Specifically, changing climate will alter soil water availability, which exerts dominant control over ecosystem structure and function in water-limited, dryland ecosystems. This research seeks...
Plant Responses to Drought and Climate Change in the Southwestern United States
Land managers face tremendous challenges in the future as drought and climate change alter the abundance, distribution, and interactions of plant species. These challenges will be especially daunting in the southwestern US, which is already experiencing elevated temperatures and prolonged droughts, resulting in reduced soil moisture in an already water-limited environment. These changes will...
RAMPS: Restoration Assessment & Monitoring Program for the Southwest
The Restoration Assessment and Monitoring Program for the Southwest (RAMPS) seeks to assist U.S. Department of the Interior (DOI) and other land management agencies in developing successful techniques for improving land condition in dryland ecosystems of the southwestern United States. Invasion by non-native species, wildfire, drought, and other disturbances are growing rapidly in extent and...
Science to Inform Riparian Ecosystem Restoration and Management
Throughout the world, riparian habitats have been dramatically modified from their natural condition. Dams, non-native species and climate change are often principal drivers of these changes, via their alteration of water and sediment regimes that determine key resources for riparian plants.
Landscape and Habitat Assessment
A central focus of this program is to conduct multi-scale assessments in order to develop related geospatial decision-support tools and methods. The program includes synthesizing broad-scale datasets and developing innovative approaches to assess the vulnerability and resilience of wildlife habitats and ecosystems, relative to land management decisions and ecosystem stressors on Department of the...
The Wyoming Landscape Conservation Initiative (WLCI)
The Wyoming Landscape Conservation Initiative (WLCI) addresses effects of land-use and climate changes on Southwest Wyoming’s natural resources. In partnership with twelve Federal, State, and local natural resource agencies, and non-governmental organizations– FORT and ten other USGS centers are conducting dozens of integrated science projects to assess the status of Southwest Wyoming’s natural...
Assessment of Wetland Area Change and Shoreline Erosion Due to Hurricane Sandy
Significant damage to coastal communities and surrounding wetlands of the north Atlantic states was caused by Hurricane Sandy in late October 2012, mostly tied to an associated storm surge of record extent and impact.
Economic Impacts of Ecological Restoration
Federal investments in ecosystem restoration projects protect Federal trusts, ensure public health and safety, and preserve and enhance essential ecosystem services. These investments also generate business activity and create jobs. However, limited information exists on the costs and associated economic impacts of ecosystem restoration projects due to the complexity of the “restoration economy”.
