The greater sage-grouse, also known as the sagehen, is the largest grouse in North America. Its range is sagebrush country in the western United States and southern Alberta and Saskatchewan, Canada. It was known as simply the sage grouse until the Gunnison sage-grouse was recognized as a separate species in 2000. The Mono Basin population of sage grouse may also be distinct.
The willow flycatcher is a small insect-eating, neotropical migrant bird of the tyrant flycatcher family. There are four subspecies of the willow flycatcher currently recognized, all of which breed in North America. Empidonax flycatchers are almost impossible to tell apart in the field so biologists use their songs to distinguish between them. The binomial commemorates the Scottish zoologist Thomas Stewart Traill.
The Endangered Species Act of 1973 is the primary law in the United States for protecting imperiled species. Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Richard Nixon on December 28, 1973. The U.S. Supreme Court called it “the most comprehensive legislation for the preservation of endangered species enacted by any nation.” The purposes of the ESA are two-fold: to prevent extinction and to recover species to the point where the law's protections are not needed. It therefore “protect[s] species and the ecosystems upon which they depend" through different mechanisms. For example, section 4 requires the agencies overseeing the Act to designate imperiled species as threatened or endangered. Section 9 prohibits unlawful ‘take,’ of such species, which means to “harass, harm, hunt...” Section 7 directs federal agencies to use their authorities to help conserve listed species. The Act also serves as the enacting legislation to carry out the provisions outlined in The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The U.S. Supreme Court found that "the plain intent of Congress in enacting" the ESA "was to halt and reverse the trend toward species extinction, whatever the cost." The Act is administered by two federal agencies, the United States Fish and Wildlife Service (FWS) and the National Marine Fisheries Service (NMFS). FWS and NMFS have been delegated the authority to promulgate rules in the Code of Federal Regulations to implement the provisions of the Act.
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use.
The California red-legged frog is a species of frog found in California (USA) and northern Baja California (Mexico). It was formerly considered a subspecies of the northern red-legged frog. The frog is an IUCN vulnerable species, and a federally listed threatened species of the United States, and is protected by law.
Amaranthus brownii was an annual herb in the family Amaranthaceae. The plant was found only on the small island of Nihoa in the Northwestern Hawaiian Islands, growing on rocky outcrops at altitudes of 120–215 m (394–705 ft). It was one of nine species of Amaranthus in the Hawaiian Islands, but was the only endemic Hawaiian species of the genus. It was first discovered during the Tanager Expedition in 1923 by botanist Edward Leonard Caum. A. brownii differed from other Hawaiian species of Amaranthus with its spineless leaf axils, linear leaves, and indehiscent fruits.
A critically endangered (CR) species is one that has been categorized by the International Union for Conservation of Nature (IUCN) as facing an extremely high risk of extinction in the wild.
The Kanab ambersnail, scientific name Oxyloma haydeni kanabense or Oxyloma kanabense, is a critically endangered subspecies or species of small, air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Succineidae, the amber snails. The common name of the amber snails is based on the shell, which is translucent and when empty usually resembles the color of amber.
The Center for Biological Diversity is a nonprofit membership organization known for its work protecting endangered species through legal action, scientific petitions, creative media and grassroots activism. It was founded in 1989 by Kieran Suckling, Peter Galvin, Todd Schulke and Robin Silver. The Center is based in Tucson, Arizona, with its headquarters in the historic Owls club building, and has offices and staff in New Mexico, Nevada, California, Oregon, Illinois, Minnesota, Alaska, Vermont, Florida and Washington, D.C. It has approximately 1.1 million members and online activists.
The bonytail chub or bonytail is a cyprinid freshwater fish native to the Colorado River basin of Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming in the southwestern United States; it has been extirpated from the part of the basin in Mexico. It was once abundant and widespread in the basin, its numbers and range have declined to the point where it has been listed as endangered since 1980 (ESA) and 1986 (IUCN), a fate shared by the other large Colorado basin endemic fish species like the Colorado pikeminnow, humpback chub, and razorback sucker. It is now the rarest of the endemic big-river fishes of the Colorado River. There are 20 species in the genus Gila, seven of which are found in Arizona.
Translocation in wildlife conservation is the capture, transport and release or introduction of species, habitats or other ecological material from one location to another. It contrasts with reintroduction, a term which is generally used to denote the introduction into the wild of species from captive stock.
The San Bernardino springsnail is an endangered species of freshwater snail in the family Hydrobiidae. This species is endemic to a small number of springs in the USA and northern Mexico.
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration.
The Socorro springsnail, scientific name Pyrgulopsis neomexicana, is an endangered species of minute freshwater snail with a gill and an operculum, an aquatic gastropod mollusk or micromollusk in the family Hydrobiidae, the mud snails.
The Sagebrush Cooperative is collaborative group based in southeastern Oregon and adjacent portions of Idaho and Nevada involving land managers, owners, and interest groups with the goal of improved management and conservation of shrub steppe systems.
Canebrake Ecological Reserve is a 6,700-acre (27 km2) nature reserve in the South Fork Valley of Kern County, 20 miles (32 km) east of Lake Isabella, California. It is located in the Southern Sierra Nevada region.
The Audubon Kern River Preserve is a riparian nature reserve owned by the National Audubon Society in the US state of California, near Weldon in Kern County.
The Montana Arctic grayling is a North American freshwater fish in the salmon family Salmonidae. The Montana Arctic grayling, native to the upper Missouri River basin in Montana and Wyoming, is a disjunct population or subspecies of the more widespread Arctic grayling. It occurs in fluvial and adfluvial, lacustrine forms. The Montana grayling is a species of special concern in Montana and had candidate status for listing under the national Endangered Species Act. It underwent a comprehensive status review by the U.S. Fish and Wildlife Service, which in 2014 decided not to list it as threatened or endangered. Current surviving native populations in the Big Hole River and Red Rock River drainages represent approximately four percent of the subspecies' historical range.
The loggerhead sea turtle, is protected under the Endangered Species Act (ESA) of 1973. It was originally listed as a threatened species on July 28, 1978. The loggerhead turtle is the most prolific species of sea turtle in U.S. coastal waters.
Endangered species as classified by the International Union for Conservation of Nature (IUCN), are species which have been categorized as very likely to become extinct in the near future. On the IUCN Red List, endangered is the second most severe conservation status for wild populations in the IUCN's schema after Critically endangered (CR). In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered (EN) worldwide. The figures for 1998 were 1,102 and 1,197 respectively.
