Proposed Revisions to Introduced Species Regulations

NOAA Proposes Revisions to Introduced Species Regulations in Four Marine Sanctuaries in California

The federal prohibition will apply to both state and federal waters within the sanctuaries. Previous sanctuary regulations for introduced species were unique to each site, and their applicability to state waters varied from sanctuary to sanctuary. The proposed rule changes will produce more consistent and streamlined regulation of introduced species within all four national marine sanctuaries in California.

In 2009, the Office of National Marine Sanctuaries had proposed a unilateral revision of the introduced species prohibition for the Monterey Bay National Marine Sanctuary, but the proposal was never finalized. The new proposal above supercedes that old proposal, so the Office of National Marine Sanctuaries has issued a Federal Register notice to withdraw the earlier proposal from further consideration. To view that withdrawl notice or comment on the notice, see For general information about introduced species (also referred to as invasive species), see
