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.
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.
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.
