The plan aims to restore several endangered species to a healthy enough condition that they no longer need the protection of the Endangered Species Act. These species are found predominantly in the tidal marshes running along 500 plus miles of the California coastline.
Their populations are threatened by habitat loss, population fragmentation, altered hydrology and salinity, non-native invasive species, predator attacks, disturbance, contamination, and sea level rise due to climate change.
