Ex situ conservation is the process of protecting an endangered species, variety or breed, of plant or animal outside its natural habitat. For example, by removing part of the population from a threatened habitat and placing it in a new location, an artificial environment which is similar to the natural habitat of the respective animal and within the care of humans, such as a zoological park or wildlife sanctuary. The degree to which humans control or modify the natural dynamics of the managed population varies widely, and this may include alteration of living environments, reproductive patterns, access to resources, and protection from predation and mortality.
The black-footed ferret, also known as the American polecat or prairie dog hunter, is a species of mustelid native to central North America.
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 Oregon Zoo, originally the Portland Zoo and later the Washington Park Zoo, is a zoo located in Washington Park, Portland, Oregon, approximately 2 miles (3.2 km) southwest of downtown Portland. Founded in 1888, it is the oldest zoo west of the Mississippi River.
Perth Zoo is a 17-hectare (41-acre) zoological park in South Perth, Western Australia. The zoo first opened in 1898 and by 2011 housed 1258 animals of 164 species and an extensive botanical collection. It is a full institutional member of the Zoo and Aquarium Association (ZAA) and the World Association of Zoos and Aquariums (WAZA).
Sagebrush steppe is a type of shrub-steppe, a plant community characterized by the presence of shrubs, and usually dominated by sagebrush, any of several species in the genus Artemisia. This ecosystem is found in the Intermountain West in the United States.
The Mexican wolf, also known as the lobo, is a subspecies of gray wolf native to southeastern Arizona and southern New Mexico in the United States, and northern Mexico. It once also ranged into western Texas. It is the smallest of North America's gray wolves, and is similar to the Great Plains wolf, though it is distinguished by its smaller, narrower skull and its darker pelt, which is yellowish-gray and heavily clouded with black over the back and tail. Its ancestors were likely the first gray wolves to enter North America after the extinction of the Beringian wolf, as indicated by its southern range and basal physical and genetic characteristics.
The black stilt or kakī (Māori) is a wading bird found in New Zealand. It is one of the world's rarest birds, with 169 adults surviving in the wild as of May 2020. Adult kakī have distinctive black plumage, long pink legs, and a long thin black bill. Black stilts largely breed in the Mackenzie Basin in the South Island, and are threatened by introduced feral cats, ferrets, and hedgehogs as well as habitat degradation from hydroelectric dams, agriculture, and invasive weeds.
The pygmy rabbit is a rabbit species native to the United States. It is also the only native rabbit species in North America to dig its own burrow. The pygmy rabbit differs significantly from species within either the Lepus (hare) or Sylvilagus (cottontail) genera and is generally considered to be within the monotypic genus Brachylagus. One isolated population, the Columbia Basin pygmy rabbit, is listed as an endangered species by the U.S. Federal government, though the International Union for Conservation of Nature lists the species as lower risk.
Captive breeding, also known as captive propagation, is the process of keeping plants or animals in controlled environments, such as wildlife reserves, zoos, botanic gardens, and other conservation facilities. It is sometimes employed to help species that are being threatened by the effects of human activities such as climate change, habitat loss, fragmentation, overhunting or fishing, pollution, predation, disease, and parasitism.
The pygmy hog is a very small and endangered species of pig and the only species in the genus Porcula. Endemic to India, the pygmy hog is a suid native of the alluvial grasslands in the foothills of the Himalayas, at elevations of up to 300 m (980 ft). Populations of pygmy hogs were once widespread in the tall, dense, wet grasslands in a narrow belt of the southern Himalayan foothills from north-western Uttar Pradesh to Assam, through southern Nepal and North Bengal, and possibly extending into contiguous habitats in southern Bhutan. Due to human encroachment and destruction of the pygmy hogs’ natural habitat, the species was thought to have gone extinct in the early 1960s. However, in 1971, a small pygmy hog population was rediscovered as they were fleeing a fire near the Barnadi Wildlife Sanctuary in Assam. Today, the only known population of pygmy hogs resides in Manas National Park in Assam, India. The population is threatened by livestock grazing, fires and poaching. With an estimated population of less than 250 mature individuals, the pygmy hog is listed as an Endangered species on the IUCN Red List, and conservation efforts such as captive breeding and re-release programs are currently being employed.
The Wyoming toad, also known commonly as Baxter's toad, is a species of toad in the family Bufonidae. The Wyoming toad is an extremely rare amphibian that exists only in captivity and within Mortenson Lake National Wildlife Refuge in Wyoming in the United States. The Wyoming toad was listed as an endangered species in 1984, and listed as extinct in the wild since 1991. As with black-footed ferrets at the Tom Thorne and Beth Williams Wildlife Research Center at Sybille in Wheatland, Wyoming, the effort to save the Wyoming toad has been a cooperative effort among state and federal agencies and private landowners. The Wyoming toad was common from the 1950s through the early 1970s, but its distribution was limited to the Laramie Basin in Albany County. The population crashed around 1975 and was extremely low by 1980. The Wyoming toad was federally listed as endangered in January 1984. To prevent extinction, a captive-breeding program began in 1989 at the Thorne Williams Unit that produced enough offspring in its first few years to supply seven zoos, and in 1998 the Saratoga National Fish Hatchery received captive-breeding stock. Nearly 46,000 offspring were produced at the Thorne Williams Unit from 1995 until 2006, when the remaining captive stock was moved to the Red Buttes Environmental Biology Laboratory south of Laramie, and then released back into the wild. Before the sharp declines occurred, this toad had been originally classified as Bufo hemiophrys baxteri, a subspecies of the Canadian toad, by Kenneth Raymond Porter in 1968.
The volcano rabbit, also known as teporingo or zacatuche, is a small rabbit that resides on the slopes of volcanoes in Mexico. It is the world's second-smallest rabbit, second only to the pygmy rabbit. It has small rounded ears, short legs, and short, thick fur and weighs approximately 390–600 g (0.86–1.3 lb). It has a life span of 7 to 9 years. The volcano rabbit lives in groups of 2 to 5 animals in burrows and runways among grass tussocks. The burrows can be as long as 5 m and as deep as 40 cm. There are usually 2 to 3 young per litter, born in the burrows. In semi-captivity, however, they do not make burrows and the young are born in nests made in the grass tussocks.
The World Association of Zoos and Aquariums (WAZA) is the "umbrella" organization for the world zoo and aquarium community. Its mission is to provide leadership and support for zoos, aquariums, and partner organizations of the world in animal care and welfare, conservation of biodiversity, environmental education and global sustainability.
The Cape Fear shiner is a North American species of freshwater fish in the family Cyprinidae. It is endemic to the central part of the state of North Carolina in the southeastern United States, and is only found in the shallow streams of the Cape Fear River basin. The fish is small and yellow with black lips and a black stripe that runs down the middle of the fish's side. This shiner is normally found in mixed schools with other minnow species. It is unique amongst its genus because it has elongated intestines that are specifically adapted to a primarily herbivorous diet. It can breed twice a year and normally lives for only two or three years in the wild. The males and females are normally similar in appearance but become different colors in the spawning season. This species of shiner was not discovered until 1962.
The Persian fallow deer is a deer species once native to all of the Middle East, but currently only living in Iran and Israel. It was reintroduced in Israel. It has been listed as endangered on the IUCN Red List since 2008. After a captive breeding program, the population has rebounded from only a handful of deer in the 1960s to over a thousand individuals.
Leptodactylus fallax, commonly known as the mountain chicken or giant ditch frog, is a critically endangered species of frog that is native to the Caribbean islands of Dominica and Montserrat. The population declined by at least 80% from 1995 to 2004, with further significant declines later. A tiny wild population remains on Dominica where there are efforts to preserve it, but few or none survive in the wild on Montserrat and its survival now relies on a captive breeding project involving several zoos. The initial decline was linked to hunting for human consumption, along with habitat loss and natural disasters, but the most serious threat now appears to be the fungal disease chytridiomycosis, which was the primary cause of the most recent rapid decline. On Montserrat it is known as the mountain chicken, while on Dominica it is known as the crapaud, which is simply the French word for "toad".
Speyeria zerene hippolyta, the Oregon silverspot, is a threatened butterfly that is found in the U.S. states of California and Oregon. It is a subspecies of Speyeria zerene.
The Beezley Hills are a range of hills, about 5 miles (8.0 km) north of Quincy in Grant County, Washington with a maximum elevation of 2,882 feet (878 m) or 2,886 feet (879.7 m).
Communal burrow refers to the habitat built by some species of mammals as a community habitat. There are some species that build burrows, but not communal burrows; and there are some species that live in communal groups, but do not construct burrows or any other type of habitat.
