We, the U.S. Fish and Wildlife Service (Service), announce findings that two species are not warranted for listing as endangered or threatened species under the Endangered Species Act of 1973, as amended (Act). After a thorough review of the best available scientific and commercial information, we find that it is not warranted at this time to list the cannulate cave isopod (Pseudobaicalasellus cannula) and Dry Fork Valley cave beetle (Pseudanophthalmus montanus). However, we ask the public to submit to us at any time any new information relevant to the status of any of the species mentioned above or their habitats.
We, the U.S. Fish and Wildlife Service (Service), propose to list the ghost orchid (Dendrophylax lindenii), a flowering plant species found in the United States in southwestern Florida and in Cuba as an endangered species under the Endangered Species Act of 1973, as amended (Act). This determination also serves as our 12-month finding on a petition to list the ghost orchid. After a review of the best scientific and commercial data available, we find that listing the species is warranted. Accordingly, we propose to list the ghost orchid as an endangered species under the Act. If we finalize this rule as proposed, it would add this species to the List of Endangered and Threatened Plants and extend the Act's protections to the species. We find that designating critical habitat for this species is not prudent.
We, the U.S. Fish and Wildlife Service (Service), determine that the northern distinct population segment (DPS) of the southern subspecies of scarlet macaw (Ara macao macao) is appropriately listed as a threatened species under the Endangered Species Act of 1973 (Act), as amended. Scarlet macaws are brilliantly colored parrots native to Mexico and Central and South America. This notification affirms the Service's February 26, 2019, final rule listing the scarlet macaw under the Act and provides a final significant portion of its range analysis for the northern DPS.
We, the U.S. Fish and Wildlife Service (Service), are removing Colorado hookless cactus (Sclerocactus glaucus) from the Federal List of Endangered and Threatened Plants. Recent taxonomic studies have indicated that the currently listed entity is actually two species: Sclerocactus glaucus and Sclerocactus dawsoniae (previously identified as S. dawsonii in the proposed rule). When we use the common name "Colorado hookless cactus" or refer to "the species" in this final rule, we are referring to information or conclusions regarding both species (S. glaucus and S. dawsoniae) as the currently listed entity. When we are referring to information or analysis pertaining to one species, we will use the new scientific names of S. glaucus or S. dawsoniae. After a review of the best available scientific and commercial information, we find that delisting Colorado hookless cactus is warranted. Our review indicates that the threats to the Colorado hookless cactus have been eliminated or reduced to the point that the species no longer meets the definition of an endangered or threatened species under the Endangered Species Act of 1973, as amended (Act). Accordingly, the prohibitions and conservation measures provided by the Act, particularly through sections 4 and 7, will no longer apply to the Colorado hookless cactus.
We, the U.S. Fish and Wildlife Service, announce that we are reopening the comment period for the proposed rule to designate critical habitat for four distinct population segments (DPSs) of the foothill yellow-legged frog (Rana boylii) under the Endangered Species Act of 1973, as amended (Act). In total, approximately 760,071 acres (307,590 hectares) in California fall within the boundaries of the proposed critical habitat designation. Comments previously submitted on the proposed rule need not be resubmitted as they are already incorporated into the public record for the rulemaking action and will be fully considered in our development of the final rule.
We, the U.S. Fish and Wildlife Service (Service), propose to list the Fish Lake Valley tui chub (Siphateles obesus ssp.), a fish found in Esmeralda County in southwestern Nevada, as an endangered species under the Endangered Species Act of 1973, as amended (Act). This determination also serves as our 12-month finding on a petition to list the Fish Lake Valley tui chub. After a review of the best scientific and commercial data available, we find that listing the Fish Lake Valley tui chub is warranted. If adopted as proposed, this rule would extend the Act's protections to the Fish Lake Valley tui chub.
We, the U.S. Fish and Wildlife Service, announce that we are reopening the comment periods for proposed rules pertaining to three insect species: monarch butterfly (Danaus plexippus), bleached sandhill skipper (Polites sabuleti sinemaculata), and Suckley's cuckoo bumble bee (Bombus suckleyi). We also announce a public hearing for the bleached sandhill skipper. Comments previously submitted on these proposed rules need not be resubmitted as they are already incorporated into the public records for these rulemaking actions and will be fully considered in our development of the final rules.
We, the U.S. Fish and Wildlife Service (Service or FWS), announce that we are extending the comment period on our January 15, 2025, proposed rule to revise the listing of the grizzly bear (Ursus arctos horribilis) in the lower-48 States under the Endangered Species Act of 1973, as amended (Act or ESA). We are extending the comment period for the proposed rule to give all interested parties adequate opportunity to comment. Comments previously submitted on the proposed rule need not be resubmitted as they are already incorporated into the public record for this rulemaking actions and will be fully considered in our development of the final rule.
In response to an order by the United States District Court for the District of Columbia, we, the U.S. Fish and Wildlife Service, are opening a public comment period related to a specific issue regarding our listing determination under the Endangered Species Act (Act) for the northern distinct population segment (DPS) of the southern subspecies of the scarlet macaw (Ara macao macao). We seek comments on the explanation presented in this document regarding why we did not conduct an analysis under section 4(e) of the Act pertaining to the DPS.
We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list the spinytail crayfish (Procambarus fitzpatricki) as an endangered or threatened species under the Endangered Species Act of 1973, as amended (Act). The spinytail crayfish is a small, burrowing freshwater crayfish endemic to southern Mississippi. After a thorough review of the best available scientific and commercial information, we find that listing the spinytail crayfish as an endangered or threatened species is not warranted at this time. However, we ask the public to submit to us at any time any new information relevant to the status of the spinytail crayfish or its habitat.
In accordance with the memorandum of January 20, 2025, from President Donald J. Trump, entitled "Regulatory Freeze Pending Review," published in the Federal Register on January 28, 2025, this action delays the effective date of the final rule NMFS published in the Federal Register on December 17, 2024, regarding the reclassification of the pillar coral (Dendrogyra cylindrus) on the Federal List of Threatened and Endangered Species.
The U.S. Nuclear Regulatory Commission (NRC) is issuing Revision 4 to Regulatory Guide (RG) 1.32, "Criteria for Power Systems for Nuclear Power Plants," and new RG 1.238, "Criteria for the Protection of Class 1E Power Systems and Equipment for Nuclear Power Plants." RG 1.32, Revision 4, describes an acceptable approach for use in complying with NRC regulations for the design, operation, and testing of electric power systems in nuclear power plants. RG 1.238 describes an acceptable approach for use in complying with NRC regulations for protection of Class 1E power systems and equipment at nuclear power plants. The NRC is also withdrawing RG 1.41, "Preoperational Testing of Redundant On-Site Electric Power Systems to Verify Proper Load Group Assignments," since its guidance is incorporated into RG 1.32, Revision 4.
We, the U.S. Fish and Wildlife Service (Service), announce 90- day findings on seven petitions to add species to, and one petition to remove a species from, the Lists of Endangered and Threatened Wildlife and Plants under the Endangered Species Act of 1973, as amended (Act). Based on our review, we find that the petitions to list the Amargosa toad (Anaxyrus nelsoni), Carson Valley monkeyflower (Erythranthe carsonensis), large marble butterfly (Euchloe ausonides) (including the large marble butterfly type subspecies (Euchloe ausonides ausonides)), Mohave ground squirrel (Xerospermophilus mohavensis), Morrison bumble bee (Bombus morrisoni), Oasis Valley population of Amargosa speckled dace (Rhinichthys nevadensis nevadensis; hereafter referred to as "Oasis Valley speckled dace"), Tennessee bottlebrush crayfish (Barbicambarus simmonsi), and one petition to delist the golden-cheeked warbler (Setophaga chrysoparia) present substantial scientific or commercial information indicating that the petitioned actions may be warranted. Therefore, with the publication of this document, we announce that we are initiating status reviews of these species to determine whether the petitioned actions are warranted. To ensure that the status reviews are comprehensive, we request scientific and commercial data and other information regarding the species and factors that may affect their status. Based on the status reviews, we will issue 12-month petition findings, which will address whether or not the petitioned actions are warranted, in accordance with the Act.
We, the U.S. Fish and Wildlife Service (Service), propose to list the big red sage (Salvia pentstemonoides), a plant species from central Texas, as an endangered species under the Endangered Species Act of 1973, as amended (Act). This determination also serves as our 12-month finding on a petition to list the big red sage. After a review of the best available scientific and commercial information, we find that listing the species is warranted. If we finalize this rule as proposed, it would add this species to the List of Endangered and Threatened Plants and extend the Act's protections to the species. We have determined that designating critical habitat for the big red sage is not prudent.
We, the U.S. Fish and Wildlife Service (Service), propose to list the Clear Lake hitch (Lavinia exilicauda chi), a freshwater fish subspecies in the North American minnow family that is restricted to the Clear Lake watershed in Lake County, California, as a threatened species under the Endangered Species Act of 1973, as amended (Act). This determination also serves as our 12-month finding on a petition to list the Clear Lake hitch. After a review of the best available scientific and commercial information, we find that listing the Clear Lake hitch is warranted. Accordingly, we propose to list the Clear Lake hitch as a threatened species with protective regulations issued under section 4(d) of the Act ("4(d) rule"). If we finalize this rule as proposed, it would add the Clear Lake hitch to the List of Endangered and Threatened Wildlife and extend the Act's protections to this subspecies.
We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to establish and delist a Northern Continental Divide Ecosystem (NCDE) distinct population segment (DPS) of the grizzly bear (Ursus arctos horribilis) in the lower-48 States. After a thorough review of the best scientific and commercial data available, we find that grizzly bears in the petitioned DPS do not, on their own, represent a valid DPS. Thus, we find that the petitioned action to establish and delist an NCDE DPS is not warranted at this time.
We, the U.S. Fish and Wildlife Service (Service or FWS), propose to revise the listing of the grizzly bear (Ursus arctos horribilis) in the lower-48 States under the Endangered Species Act of 1973, as amended (Act or ESA). After a review of the best scientific and commercial data available, we affirm that the currently listed grizzly bear population meets our requirements for consideration as a distinct population segment (DPS) under the Act and that the population remains likely to become an endangered species within the foreseeable future. However, we find that clarification of the geographic areas included within the DPS is warranted. Therefore, we propose to revise the listing by defining the boundaries of the contiguous U.S. grizzly bear DPS. The revised entity would include all geographic portions of the currently listed lower-48 entity that contain suitable habitat and where grizzly bears are currently found or are likely to be found in the future as populations recover. This area includes all of Washington and portions of Idaho, Montana, and Wyoming. The contiguous U.S. grizzly bear DPS would retain threatened species status. This proposed rule would promote conservation of the grizzly bear by ensuring that the listing under the Act explicitly reflects the areas where grizzly bears currently occur and are likely to occur in the future. Clarifying that the listing does not include areas outside of the grizzly bear's historical range will assist as recovery proceeds. We are also proposing to revise protective regulations for the grizzly bear issued under section 4(d) of the Act.
We, the U.S. Fish and Wildlife Service (Service), propose to designate critical habitat for the San Francisco Bay-Delta distinct population segment (DPS) of the longfin smelt (Spirinchus thaleichthys), a fish species from the San Francisco Bay estuary in California, under the Endangered Species Act of 1973, as amended (Act). In total, approximately 91,630 acres (37,082 hectares) in California fall within the boundaries of the proposed critical habitat designation. We also announce the availability of an economic analysis of the proposed designation of critical habitat for the species.
We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to establish and delist a Greater Yellowstone Ecosystem (GYE) distinct population segment (DPS) of the grizzly bear (Ursus arctos horribilis) in the lower-48 States. After a thorough review of the best scientific and commercial data available, we find that grizzly bears in the petitioned DPS do not, on their own, represent a valid DPS. Thus, we find that the petitioned action to establish and delist a GYE DPS is not warranted at this time.
We, the U.S. Fish and Wildlife Service (Service), propose to designate critical habitat for four distinct population segments (DPSs) of the foothill yellow-legged frog (Rana boylii) under the Endangered Species Act of 1973, as amended (Act). In total, approximately 760,071 acres (307,590 hectares) in California fall within the boundaries of the proposed critical habitat designation. We also announce the availability of an economic analysis of the proposed designation of critical habitat for four DPSs.
We, the U.S. Fish and Wildlife Service (Service), propose to list the two subspecies of the West Indian manatee, the Florida manatee (Trichechus manatus latirostris) and the Antillean manatee (Trichechus manatus manatus), under the Endangered Species Act of 1973, as amended (Act). We have conducted status reviews for the two subspecies, and, as a result, we are proposing to list the Florida manatee as a threatened species with protective regulations under section 4(d) of the Act ("4(d) rule"), and the Antillean manatee as an endangered species, under the Act. These two listings would replace the current threatened species listing of the West Indian manatee (Trichechus manatus). This determination also serves as our 12-month findings on two petitions and as our completed 5-year review of the West Indian manatee. If we finalize this rule as proposed, it would remove the West Indian manatee from the Federal List of Endangered and Threatened Wildlife (List), add the Florida manatee and Antillean manatee to the List, and extend the Act's protections to the Florida manatee and Antillean manatee.
