Forster’s Tern Chick Survival in Response to a Managed Relocation of Predatory California Gulls
Gull populations can severely limit the productivity of waterbirds. Relocating gull colonies may reduce their effects on nearby breeding waterbirds, but there are few examples of this management strategy.
Evaluation of Caspian Tern (Hydroprogne caspia) and Snowy Plover (Charadrius alexandrinus nivosus) Nesting on Modified Islands at the Don Edwards San Francisco Bay National Wildlife Refuge, California—2015 Annual Report
In order to address the 2008/10 NOAA Fisheries Biological Opinion for operation of the Federal Columbia River Power System, the U.S.
The Critical Role of Islands for Waterbird Breeding and Foraging Habitat in Managed Ponds of the South Bay Salt Pond Restoration Project, South San Francisco Bay, California
The South Bay Salt Pond Restoration Project aims to restore 50–90 percent of former salt evaporation ponds into tidal marsh in South San Francisco Bay, California. However, large numbers of waterbirds use these ponds annually as nesting and foraging habitat.
Effects of Human Disturbance on Waterbird Nesting Effort and Reproductive Success at Restoration Pond SF2, South San Francisco Bay, California
To offset for the loss of managed pond habitat during restoration of wetlands to tidal marsh, the South Bay Salt Pond Restoration Project is enhancing some of the remaining ponds by constructing islands for roosting and nesting waterbirds.
Waterbird Egg Mercury Concentrations in Response to Wetland Restoration in South San Francisco Bay, California
The conversion of 50–90 percent of 15,100 acres of former salt evaporation ponds to tidal marsh habitat in the south San Francisco Bay, California, is planned as part of the South Bay Salt Pond Restoration Project.
Impact of Salt Ponds Restoration on California Gull Displacement and Predation on Breeding Waterbirds
The California Gull (Larus californicus) population in the South San Francisco Bay has increased from fewer to 200 breeding Gulls in 1982, to a peak of 52,172 in 2012. Specific to this study there were 46,030 breeding Gulls in 2010 and 37,716 breeding Gulls in 2011.
The South Bay Mercury Project: Using Biosentinels to Monitor Effects of Wetland Restoration for the South Bay Salt Pond Restoration Project
The South Bay Salt Pond Restoration Project plans to convert 50-90% of the former salt evaporation ponds of South San Francisco Bay into tidal marsh habitat. This large-scale habitat restoration may change the distribution, bioavailability, and bioaccumulation of methylmercury.
The South Bay Mercury Project: Using Biosentinels to Monitor Effects of Wetland Restoration for the South Bay Salt Pond Restoration Project (Waterbird Mercury Component)
The South Bay Salt Pond Restoration Project plans to convert 50-90% of the former salt evaporation ponds of South San Francisco Bay into tidal marsh habitat. This large-scale habitat restoration may change the distribution, bioavailability, and bioaccumulation of methylmercury.
Annual Report: The Critical Role of Islands for Waterbird Breeding and Foraging Habitat in Managed Ponds of the South Bay Salt Pond Restoration Project and Impacts of Disturbance on Breeding Waterbirds in Pond SF2
In this report we document activities from March 31, 2012 to June 30, 2012, by task, and summarize the project’s current results. This is the sixth quarterly report and the first annual report for the project.
Waterbird Nest Monitoring Program in San Francisco Bay (2005–10)
Open-File Report 2012–1145. Here, we provide a summary of nesting ecology data for Forster’s Terns, American Avocets, and Black-necked Stilts, collected from 2005 to 2010 in the areas of the South Bay Salt Pond Restoration Project.
Response of Waterbird Breeding Effort, Nest Success, and Mercury Concentrations in Eggs and Fish to Wetland Management
In cooperation with the Don Edwards San Francisco Bay National Wildlife Refuge, we experimentally manipulated water levels in pond A12 to examine the response of waterbird breeding effort and nest success, and assess the unintended consequence of this management action on the bioaccumulation of m
Impact of Salt Pond Restoration on California Gull Displacement and Predation on Breeding Waterbirds - Annual Report 2010
Our objectives are to determine the impact of gulls on breeding snowy plovers and Forster’s terns.; Color-mark California gulls at A6 to determine potential nesting distributions after restoration of A6.; Continue our California gull colony surveys to document current population size.
The Effects of Wetland Restoration on Mercury Bioaccumulation in the South Bay Salt Pond Restoration Project: Using the Biosentinel Toolbox to Monitor Changes Across Multiple Habitats and Spatial Scales
The project was initiated in April 2010, and to date has included four sampling events of surface water (April, May, June/July, and August 2010) and five sampling events of biota (April, May, June/July, August, and September 2010) and three sampling events for surface sediment (May, June/July, an
California Gull Distribution, Abundance, and Predation on Waterbird Eggs and Chicks in South San Francisco Bay
We examined the distribution and abundance of California Gulls throughout the South Bay salt ponds and associated landfills and determined their impact on the reproductive success of American Avocets and Black-necked Stilts.
