  • Listing a Species As a Threatened Or Endangered Species Section 4 of the Endangered Species Act
    U.S. Fish & Wildlife Service Listing a Species as a Threatened or Endangered Species Section 4 of the Endangered Species Act The Endangered Species Act of 1973, as amended, is one of the most far- reaching wildlife conservation laws ever enacted by any nation. Congress, on behalf of the American people, passed the ESA to prevent extinctions facing many species of fish, wildlife and plants. The purpose of the ESA is to conserve endangered and threatened species and the ecosystems on which they depend as key components of America’s heritage. To implement the ESA, the U.S. Fish and Wildlife Service works in cooperation with the National Marine Fisheries Service (NMFS), other Federal, State, and local USFWS Susanne Miller, agencies, Tribes, non-governmental Listed in 2008 as threatened because of the decline in sea ice habitat, the polar bear may organizations, and private citizens. spend time on land during fall months, waiting for ice to return.

  • Lagenodelphis Hosei – Fraser's Dolphin
    Lagenodelphis hosei – Fraser’s Dolphin Assessment Rationale The species is suspected to be widespread and abundant and there have been no reported population declines or major threats identified that could cause a range-wide decline. Globally, it has been listed as Least Concern and, within the assessment region, it is not a conservation priority and therefore, the regional change from Data Deficient to Least Concern reflects the lack of major threats to the species. The most prominent threat to this species globally may be incidental capture in fishing gear and, although this is not considered a major threat to this species in the assessment region, Fraser’s Dolphins have become entangled in anti-shark nets off South Africa’s east coast. This threat should be monitored. Regional Red List status (2016) Least Concern Regional population effects: Fraser’s Dolphin has a widespread, pantropical distribution, and although its National Red List status (2004) Data Deficient seasonal migration patterns in southern Africa remain Reasons for change Non-genuine change: inconclusive, no barriers to dispersal have been New information recognised, thus rescue effects are possible. Global Red List status (2012) Least Concern TOPS listing (NEMBA) (2007) None Distribution The distribution of L. hosei is suggested to be pantropical CITES listing (2003) Appendix II (Robison & Craddock 1983), and is widespread across the Endemic No Pacific and Atlantic Oceans (Ross 1984), and the species has been documented in the Indian Ocean off South This species is occasionally Africa’s east coast (Perrin et al. 1973), in Sri Lanka misidentified as the Striped Dolphin (Stenella (Leatherwood & Reeves 1989), Madagascar (Perrin et al.

  • How Do the Extinctions of Other Creatures Affect Humans Directly?
    4/30/2020 How Do the Extinctions of Other Creatures Affect Humans Directly? How Do the Extinctions of Other Creatures Affect Humans Directly? ••• Updated March 10, 2018 By Milton Kazmeyer While extinction of animal species is part of the natural process of evolution, the expansion of the human species has led to significant increases in the extinction rate. Because humans share ecosystems with endangered species, our quality of life and our survival is linked to them. Habitat destruction, climate change, resource depletion and other factors have increased the extinction rate by a factor of 1,000, putting substantial pressure on thousands of the most vulnerable creatures on the planet. American Bison One example of how the depletion of a species affected humans is what occurred after the American bison nearly vanished in the 19th century. Originally, the bison was a common animal on the central plains, with an estimated population of 15 million, and the Native Americans of the region depended on the animal for food, leather, fur and many https://sciencing.com/extinctions-other-creatures-affect-humans-directly-20692.html 1/11 4/30/2020 How Do the Extinctions of Other Creatures Affect Humans Directly? other goods vital to a nomadic lifestyle. By 1890, however, there were only a few thousand bison left in America. Tribal hunters were able to kill more of the animals with the aid of firearms, and in some cases the United States government encouraged the widespread slaughter of bison herds. The vanishing species forced tribes dependent on the animal to move to new lands in search of food, and eventually those tribes could no longer support themselves and had to deal with the United States government for survival.

  • PETITION to LIST the Western Ridged Mussel
    PETITION TO LIST The Western Ridged Mussel Gonidea angulata (Lea, 1838) AS AN ENDANGERED SPECIES UNDER THE U.S. ENDANGERED SPECIES ACT Photo credit: Xerces Society/Emilie Blevins Submitted by The Xerces Society for Invertebrate Conservation Prepared by Emilie Blevins, Sarina Jepsen, and Sharon Selvaggio August 18, 2020 The Honorable David Bernhardt Secretary, U.S. Department of Interior 1849 C Street, NW Washington, DC 20240 Dear Mr. Bernhardt: The Xerces Society for Invertebrate Conservation hereby formally petitions to list the western ridged mussel (Gonidea angulata) as an endangered species under the Endangered Species Act, 16 U.S.C. § 1531 et seq. This petition is filed under 5 U.S.C. 553(e) and 50 CFR 424.14(a), which grants interested parties the right to petition for issue of a rule from the Secretary of the Interior. Freshwater mussels perform critical functions in U.S. freshwater ecosystems that contribute to clean water, healthy fisheries, aquatic food webs and biodiversity, and functioning ecosystems. The richness of aquatic life promoted and supported by freshwater mussel beds is analogous to coral reefs, with mussels serving as both structure and habitat for other species, providing and concentrating food, cleaning and clearing water, and enhancing riverbed habitat. The western ridged mussel, a native freshwater mussel species in western North America, once ranged from San Diego County in California to southern British Columbia and east to Idaho. In recent years the species has been lost from 43% of its historic range, and the southern terminus of the species’ distribution has contracted northward approximately 475 miles. Live western ridged mussels were not detected at 46% of the 87 sites where it historically occurred and that have been recently revisited.

  • Rare Or Threatened Vascular Plant Species of Wollemi National Park, Central Eastern New South Wales
    Rare or threatened vascular plant species of Wollemi National Park, central eastern New South Wales. Stephen A.J. Bell Eastcoast Flora Survey PO Box 216 Kotara Fair, NSW 2289, AUSTRALIA Abstract: Wollemi National Park (c. 32o 20’– 33o 30’S, 150o– 151oE), approximately 100 km north-west of Sydney, conserves over 500 000 ha of the Triassic sandstone environments of the Central Coast and Tablelands of New South Wales, and occupies approximately 25% of the Sydney Basin biogeographical region. 94 taxa of conservation signiicance have been recorded and Wollemi is recognised as an important reservoir of rare and uncommon plant taxa, conserving more than 20% of all listed threatened species for the Central Coast, Central Tablelands and Central Western Slopes botanical divisions. For a land area occupying only 0.05% of these divisions, Wollemi is of paramount importance in regional conservation. Surveys within Wollemi National Park over the last decade have recorded several new populations of signiicant vascular plant species, including some sizeable range extensions. This paper summarises the current status of all rare or threatened taxa, describes habitat and associated species for many of these and proposes IUCN (2001) codes for all, as well as suggesting revisions to current conservation risk codes for some species. For Wollemi National Park 37 species are currently listed as Endangered (15 species) or Vulnerable (22 species) under the New South Wales Threatened Species Conservation Act 1995. An additional 50 species are currently listed as nationally rare under the Briggs and Leigh (1996) classiication, or have been suggested as such by various workers. Seven species are awaiting further taxonomic investigation, including Eucalyptus sp.
