Enderby Island Cattle are a breed of cattle that existed in a wild state in isolation on Enderby Island, New Zealand for over 80 years. Only about seven specimens remain today (all on mainland New Zealand), after a rescue expedition by the Rare Breeds Conservation Society of New Zealand (RBCSNZ), and a culling program to protect the native flora and fauna of Enderby Island. There have since been intensive efforts at breeding the cattle, involving both in vitro fertilisation and cloning, and there is an ongoing program to perpetuate the breed in captivity. [1]
Nine cattle (the exact breed remains obscure) were introduced to Enderby Island, the northernmost of the subantarctic Auckland Islands group, in the 1890s when an attempt was made to establish farming on the island. The attempt failed because of the climate, with the island being abandoned in 1910 and the cattle left behind. Over the 80 years of subsequent isolation the cattle survived well despite the harsh climate, feeding on Enderby's scrub vegetation, southern rata, and seaweed, evolving to cope with the environment. [1] Cattle had been released earlier, also, in an effort to provide food for castaways.
In 1991, New Zealand's Department of Conservation decided that species introduced to the Auckland Islands, including cattle and rabbits, should be culled in the course of a program to restore the natural ecosystem. An expedition that year eradicated 47 of an estimated 53 cattle on the island. Genetic material (oocytes and epididymal sperm) was taken and stored. A 1992 expedition by the RBCSNZ, to rescue live specimens of the Enderby Island Rabbit, found tracks of two remaining cattle, a cow and her calf, which were later captured and transferred to New Zealand. [1]
The cattle originally introduced to Enderby Island were described (in the ship's log) as 'shorthorn'. However, their descendants do not look much like modern shorthorns and are more similar to Shetland cattle. They are typically black and white, but three of the 47 cattle culled in 1991 were described as being red and white, and they were probably not a pure breed originally. They are small cattle with long bodies and short legs, giving them a distinctive appearance. [1]
The Auckland Islands are an archipelago of New Zealand, lying 465 kilometres (290 mi) south of the South Island. The main Auckland Island, occupying 510 km2 (200 sq mi), is surrounded by smaller Adams Island, Enderby Island, Disappointment Island, Ewing Island, Rose Island, Dundas Island, and Green Island, with a combined area of 626 km2 (240 sq mi). The islands have no permanent human inhabitants.
Macquarie Island is an island in the southwestern Pacific Ocean, about halfway between New Zealand and Antarctica. Regionally part of Oceania and politically a part of Tasmania, Australia, since 1900, it became a Tasmanian State Reserve in 1978 and was inscribed as a UNESCO World Heritage Site in 1997.
Auckland Island is the main island of the eponymous uninhabited archipelago in the Pacific Ocean. It is part of the New Zealand subantarctic area. It is inscribed in the UNESCO World Heritage list together with the other New Zealand Subantarctic Islands in the region.
The Galloway is a Scottish breed of beef cattle, named after the Galloway region of Scotland, where it originated during the seventeenth century.
The Dairy Shorthorn is a British breed of dairy cattle. It derives from the Shorthorn cattle of Teesside, in the North Riding of Yorkshire and in Northumbria in north-eastern England. The Shorthorn was for this reason at first known as the Durham or Teeswater.
Campbell Island / Motu Ihupuku is an uninhabited subantarctic island of New Zealand, and the main island of the Campbell Island group. It covers 112.68 square kilometres (43.51 sq mi) of the group's 113.31 km2 (43.75 sq mi), and is surrounded by numerous stacks, rocks and islets like Dent Island, Folly Island, Isle de Jeanette-Marie, and Jacquemart Island, the latter being the southernmost extremity of New Zealand. The island is mountainous, rising to over 500 metres (1,640 ft) in the south. A long fiord, Perseverance Harbour, nearly bisects it, opening out to sea on the east coast.
Enderby Island is part of New Zealand's uninhabited Auckland Islands archipelago, south of mainland New Zealand. It is situated just off the northern tip of Auckland Island, the largest island in the archipelago.
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 Shorthorn breed of cattle originated in the North East of England in the late eighteenth century. The breed was developed as dual-purpose, suitable for both dairy and beef production; however, certain blood lines within the breed always emphasised one quality or the other. Over time, these different lines diverged, and by the second half of the twentieth century, two separate breeds had developed – the Beef Shorthorn, and the Milking Shorthorn. All Shorthorn cattle are coloured red, white, or roan, although roan cattle are preferred by some, and completely white animals are not common. However, one type of Shorthorn has been bred to be consistently white – the Whitebred Shorthorn, which was developed to cross with black Galloway cattle to produce a popular blue roan crossbreed, the Blue Grey.
The Santa Gertrudis is an American breed of beef cattle. It is a taurine-indicine hybrid breed, descended from both zebu and European cattle. It was bred in the early twentieth century in Texas, and received official recognition in 1940. It has been exported to many countries including Australia, Brazil and South Africa, and has contributed to the development of a number of modern breeds, among them the Barzona and the Droughtmaster.
The northern royal albatross or toroa, is a large seabird in the albatross family. It was split from the closely related southern royal albatross as recently as 1998, though not all scientists support that conclusion and some consider both of them to be subspecies of the royal albatross.
The Livestock Conservancy, formerly known as the American Livestock Breeds Conservancy (ALBC) and prior to that, the American Minor Breeds Conservancy, is a nonprofit organization focused on preserving and promoting rare breeds, also known as "heritage breeds" of livestock. Founded in 1977, through the efforts of livestock breed enthusiasts concerned about the disappearance of many of the US's heritage livestock breeds, The Livestock Conservancy was the pioneer livestock preservation organization in the United States, and remains a leading organization in that field. It has initiated programs that have saved multiple breeds from extinction, and works closely with similar organizations in other countries, including Rare Breeds Canada. With 3,000 members, a staff of eleven and a 19-member board of directors, the organization has an operating budget of over a million dollars.
The Enderby Island Rabbit, or simply Enderby rabbit or Enderby, is a rare breed of domesticated European rabbit. It originates from rabbits introduced to Enderby Island, an uninhabited subantarctic island in New Zealand’s Auckland Islands group, from Australia in October 1865 to serve as castaway food. Over 130 years the isolated population became a distinctive variety. The rabbits were eventually exterminated for wildlife management from Enderby Island in the early 1990s, but a breeding group of 49 rabbits was rescued by the Rare Breeds Conservation Society of New Zealand in September 1992. Since then rabbit breeders have maintained numbers at around 100-150 individuals, primarily through the work of Sitereh Schouten and the Enderby Island Rabbit Club of NZ. They have ensured breed purity with pedigrees and ear tattoos which exclusively include a Z along with an individual number.
The Rare Breeds Conservation Society of New Zealand (RBCSNZ) was founded in 1988 to conserve, record and promote rare livestock breeds with the aim of maintaining genetic diversity within livestock species. The area of coverage is broad, and includes poultry as well as camelids, cattle, chinchillas, deer, donkeys, goats, horses, pigs, rabbits and sheep.
The Auckland Island pig is a feral landrace of domestic pig found on subantarctic Auckland Island, New Zealand. Its ancestors have inhabited the island since 1807, and, as an invasive species, has had a considerable environmental impact.
Campbell Island cattle were a feral breed of domestic cattle found on Campbell Island, New Zealand. From photographs taken in 1976 it appeared that the cattle were at least partly of shorthorn origin. This breed is now extinct.
