{"abstract":"We, the U.S. Fish and Wildlife Service (Service), determine endangered status pursuant to the Endangered Species Act of 1973, as amended (Act), for the Buena Vista Lake shrew (Sorex ornatus relictus). This subspecies is endemic to Kern County, California, and is currently known from only four locations. This subspecies is imperiled primarily by habitat loss and modification due to agricultural activities, unnatural 1 hydrological conditions, incompatible water management practices, the possible toxic effects of selenium poisoning, modification or loss of genetic integrity from introgression (hybridization), and the loss of populations caused by random naturally occurring events. This final rule extends the Federal protection and recovery provisions of the Act for the Buena Vista Lake shrew.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF THE INTERIOR","name":"Interior Department","id":253,"url":"https://www.federalregister.gov/agencies/interior-department","json_url":"https://www.federalregister.gov/api/v1/agencies/253","parent_id":null,"slug":"interior-department"},{"raw_name":"Fish and Wildlife Service","name":"Fish and Wildlife Service","id":197,"url":"https://www.federalregister.gov/agencies/fish-and-wildlife-service","json_url":"https://www.federalregister.gov/api/v1/agencies/197","parent_id":253,"slug":"fish-and-wildlife-service"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2002/03/06/02-5274.html","cfr_references":[{"chapter":null,"citation_url":null,"part":17,"title":50}],"citation":"67 FR 10101","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective April 5, 2002.","disposition_notes":null,"docket_ids":[],"dockets":[],"document_number":"02-5274","effective_on":"2002-04-05","end_page":10113,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2002/03/06/02-5274.xml","html_url":"https://www.federalregister.gov/documents/2002/03/06/02-5274/endangered-and-threatened-wildlife-and-plants-endangered-status-for-the-buena-vista-lake-shrew-sorex","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/02-5274?publication_date=2002-03-06","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2002-03-06/02-5274/mods.xml","not_received_for_publication":null,"page_length":13,"page_views":{"count":689,"last_updated":"2026-04-03 22:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2002-03-06/pdf/02-5274.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2002-03-06","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2002/03/06/02-5274.txt","regulation_id_number_info":{"1018-AG04":{"issue":"200110","html_url":"https://www.federalregister.gov/regulations/1018-AG04/endangered-and-threatened-wildlife-and-plants-listing-of-buena-vista-lake-shrew-as-endangered","title":"Endangered and Threatened Wildlife and Plants; Listing of Buena Vista Lake Shrew as Endangered","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200110&RIN=1018-AG04&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["1018-AG04"],"regulations_dot_gov_info":{},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":10101,"subtype":null,"title":"Endangered and Threatened Wildlife and Plants; Endangered Status for the Buena Vista Lake Shrew (Sorex Ornatus Relictus)","toc_doc":"Buena Vista Lake shrew","toc_subject":"Endangered and threatened species:","topics":["Endangered and threatened species","Exports","Imports","Reporting and recordkeeping requirements","Transportation"],"type":"Rule","volume":67}
