In 2005, PRBO Conservation Science led a multi-partner effort to develop standardized survey protocols and determine population size and trends for the endangered California Clapper Rail in the San Francisco Bay Estuary. Partners contributing to the standardized protocol dataset included the U. S. Fish and Wildlife Service, California Department of Fish and Game, California Coastal Conservancy’s San Francisco Estuary Invasive Spartina Project, Avocet Research Associates, and East Bay Regional Park District.
