The Cullinan Ranch Restoration Project will be monitored for a period of at least 15 years, as required by state and federal permits, and the US Fish and Wildlife Service will continue monitoring and managing the site over a longer time period to ensure the project is progressing towards long term habitat goals.  Typical monitoring includes water quality, biosentinel monitoring for methylmercury, vegetation colonization, sedimentation/erosion, and breach development.  Once vegetation is well established, monitoring for species such as salt marsh harvest mouse and California clapper rail will begin.
