{"abstract":"We, the National Marine Fisheries Service (NMFS), are issuing a final rule under the Endangered Species Act (ESA) of 1973, as amended, that redefines the geographic range of the endangered Central California Coast (CCC) coho salmon (Oncorhynchus kisutch) Evolutionarily Significant Unit (ESU) to include all naturally spawned populations of coho salmon that occur in Soquel and Aptos creeks. Information supporting this boundary change includes recent observations of coho salmon in Soquel Creek, genetic analysis of these fish indicating they are derived from other nearby populations in the ESU, and the presence of freshwater habitat conditions and watershed processes in Soquel and Aptos Creeks that are similar to those found in closely adjacent watersheds that support coho salmon populations that are part of the ESU. We have also reassessed the status of this ESU throughout its redefined range and conclude that it continues to be endangered.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF COMMERCE","name":"Commerce Department","id":54,"url":"https://www.federalregister.gov/agencies/commerce-department","json_url":"https://www.federalregister.gov/api/v1/agencies/54","parent_id":null,"slug":"commerce-department"},{"raw_name":"National Oceanic and Atmospheric Administration","name":"National Oceanic and Atmospheric Administration","id":361,"url":"https://www.federalregister.gov/agencies/national-oceanic-and-atmospheric-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/361","parent_id":54,"slug":"national-oceanic-and-atmospheric-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2012/04/02/2012-7860.html","cfr_references":[{"chapter":null,"citation_url":null,"part":224,"title":50}],"citation":"77 FR 19552","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective June 1, 2012.","disposition_notes":null,"docket_ids":["Docket No. 100323162-2182-03"],"dockets":[],"document_number":"2012-7860","effective_on":"2012-06-01","end_page":19563,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2012/04/02/2012-7860.xml","html_url":"https://www.federalregister.gov/documents/2012/04/02/2012-7860/endangered-and-threatened-species-range-extension-for-endangered-central-california-coast-coho","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2012-7860?publication_date=2012-04-02","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2012-04-02/2012-7860/mods.xml","not_received_for_publication":null,"page_length":12,"page_views":{"count":562,"last_updated":"2026-09-21 12:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2012-04-02/pdf/2012-7860.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2012-07860.pdf?1333122254","publication_date":"2012-04-02","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2012/04/02/2012-7860.txt","regulation_id_number_info":{"0648-XV30":null},"regulation_id_numbers":["0648-XV30"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Update status information for Central California Coast Coho Salmon ESU","document_id":"NOAA-NMFS-2010-0058-0008"},{"title":"Pending of Biological Review Team concerning the southern boundary of the Central California Coho Salmon ESU","document_id":"NOAA-NMFS-2010-0058-0007"},{"title":"References Cited List","document_id":"NOAA-NMFS-2010-0058-0006"},{"title":"Addendum to the Petition to Redefine the Southern Extent of the Central California Coho","document_id":"NOAA-NMFS-2010-0058-0003"},{"title":"Petition to redefine the southern extent of the Central California Coho ESU","document_id":"NOAA-NMFS-2010-0058-0002"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=NOAA-NMFS-2010-0058","supporting_documents_count":5,"docket_id":"NOAA-NMFS-2010-0058","regulation_id_number":"0648-XV30","title":"Endangered and Threatened Species; 90-Day Finding on a Petition to Delist Coho Salmon South of San Francisco Bay.","checked_regulationsdotgov_at":"2012-04-27T21:54:37Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":19552,"subtype":null,"title":"Endangered and Threatened Species; Range Extension for Endangered Central California Coast Coho Salmon","toc_doc":"Range Extension for Endangered Central California Coast Coho Salmon","toc_subject":"Endangered and Threatened Species:","topics":[],"type":"Rule","volume":77}
