7560-449: The end of this interval. Oceans continued to be relatively warm during the Pliocene, though they continued cooling. The Arctic ice cap formed , drying the climate and increasing cool shallow currents in the North Atlantic. Deep cold currents flowed from the Antarctic. The formation of the Isthmus of Panama about 3.5 million years ago cut off the final remnant of what was once essentially a circum-equatorial current that had existed since
7668-400: The far south of the island. Around the same time, a group of Māori migrated to Rēkohu (the Chatham Islands ), where, in adapting to the local climate and the availability of resources, they eventually evolved into a separate people known as the Moriori with its own distinct language – closely related to the parent culture and language in mainland New Zealand . One notable feature of
7776-546: The first Chinese migrants had been invited by the Otago Provincial government, they quickly became the target of hostility from white settlers and laws were enacted specifically to discourage them from coming to New Zealand. The South Island has no separately represented country subdivision , but is guaranteed 16 of the electorates in the New Zealand House of Representatives . A two-tier structure constituted under
7884-543: The first time since the Cretaceous , with North American rodents and primates mixing with southern forms. Litopterns and the notoungulates , South American natives, were mostly wiped out, except for the macrauchenids and toxodonts , which managed to survive. Small weasel-like carnivorous mustelids , coatis and short-faced bears migrated from the north. Grazing glyptodonts , browsing giant ground sloths and smaller caviomorph rodents , pampatheres , and armadillos did
7992-486: The four brothers into the mountain ranges on top of it. Charcoal drawings can be found on limestone rock shelters in the centre of the South Island, with over 550 sites stretching from Kaikōura to North Otago . The drawings are estimated to be between 500 and 800 years old and portray animals, people and fantastic creatures, possibly stylised reptiles. Some of the birds pictured are long extinct, including moa and Haast's eagles . They were drawn by early Māori , but by
8100-527: The highest population densities in the nation) and some other dolphins including killer whales can be observed close to shores as well. For whales, their number is still very small, but various species have been observed. Although Paparoa National Park is protected from mining by Schedule 4 of the Crown Minerals Act, there have been proposals to allow some mining within the park's borders. On 22 March 2010, Gerry Brownlee (Minister of Energy and Resources) and Kate Wilkinson (Minister of Conservation) released
8208-591: The historical Waitaha , with major settlements including in Kaiapoi Pā near modern-day Christchurch . During the Musket Wars expanding iwi colonised Te Tau Ihu , a region comprising parts of modern-day Tasman , Nelson and Malborough , including Ngāti Kuia , Rangitāne , Ngāti Tama , and later Ngāti Toarangatira after Te Rauparaha's wars of conquest. British settlement began with expansive and cheap land purchases early on, and settlers quickly outnumbered Māori. As
8316-413: The influence of seasonal variation. More recent research has emphasized the variability selection hypothesis, which proposes that variability in climate fostered development of hominin traits. Improved climate proxies show that the Pliocene climate of east Africa was highly variable, suggesting that adaptability to varying conditions was more important in driving hominin evolution than the steady pressure of
8424-537: The island from north to south. They include New Zealand's highest peak, Aoraki / Mount Cook , at 3,724 metres (12,218 feet). The high Kaikōura Ranges lie to the northeast. The east side of the island is home to the Canterbury Plains , while the West Coast is renowned for its rough coastlines, such as Fiordland , a very high proportion of native bush and national parks , and the Fox and Franz Josef Glaciers . With
8532-570: The island's name phonetically as "Toai poonamoo". In the 19th century, some maps identified the South Island as Middle Island or New Munster (named after Munster province in Southern Ireland) with the name South Island or New Leinster was used for today's Stewart Island / Rakiura . In 1907, the Minister for Lands gave instructions to the Land and Survey Department that the name Middle Island
8640-576: The late Pliocene or early Quaternary periods. Mt Lodge, the highest mountain in the park at 1,447 metres (4,747 ft), has rocks that are the oldest in New Zealand. Over the last 10 million years, the movement of the Alpine Fault has separated the predominantly granite and gneiss rocks of the Paparoas from their original neighbours, so that they now more closely resemble the rocks in Fiordland , far to
8748-460: The late Zanclean, Italy remained relatively warm and humid. Central Asia became more seasonal during the Pliocene, with colder, drier winters and wetter summers, which contributed to an increase in the abundance of C 4 plants across the region. In the Loess Plateau , δ13C values of occluded organic matter increased by 2.5% while those of pedogenic carbonate increased by 5% over the course of
8856-727: The majority in all districts of the South Island, ranging from 75.9% in Christchurch City to 92.1% in the Waimakariri district . The proportion of South Islanders born overseas at the 2018 census was 21.4%. The most common foreign countries of birth are England (22.0% of overseas-born residents), Australia (8.8%), the Philippines (7.9%), Mainland China (6.5%) and India (5.4%). Around 48.6 percent of South Islanders affiliate with Christianity and 3.1 percent affiliate with non-Christian religions, while 45.8 percent are irreligious. Anglicanism
8964-518: The mouth of the Patea River ), and New Munster Province (and the southern portion of the North Island , up to the mouth of the Patea River , the South Island and Stewart Island). Each province had a Governor and Legislative and Executive Council, in addition to the Governor-in-Chief and Legislative and Executive Council for the whole colony. The 1846 Constitution Act was later suspended, and only
9072-774: The now-separated Atlantic Ocean. Africa 's collision with Europe formed the Mediterranean Sea , cutting off the remnants of the Tethys Ocean . The border between the Miocene and the Pliocene is also the time of the Messinian salinity crisis . During the Late Pliocene, the Himalayas became less active in their uplift, as evidenced by sedimentation changes in the Bengal Fan . The land bridge between Alaska and Siberia ( Beringia )
9180-674: The official timescale of the ICS , the Pliocene is subdivided into two stages . From youngest to oldest they are: The Piacenzian is sometimes referred to as the Late Pliocene, whereas the Zanclean is referred to as the Early Pliocene. In the system of In the Paratethys area (central Europe and parts of western Asia) the Pliocene contains the Dacian (roughly equal to the Zanclean) and Romanian (roughly equal to
9288-556: The onset of continental glaciation in the Arctic, suggesting that vegetation changes in Australia during the Pliocene behaved similarly to during the Late Pleistocene and were likely characterised by comparable cycles of aridity and humidity. The equatorial Pacific Ocean sea surface temperature gradient was considerably lower than it is today. Mean sea surface temperatures in the east were substantially warmer than today but similar in
9396-400: The opposite, migrating to the north and thriving there. The marsupials remained the dominant Australian mammals, with herbivore forms including wombats and kangaroos , and the huge Diprotodon . Carnivorous marsupials continued hunting in the Pliocene, including dasyurids , the dog-like thylacine and cat-like Thylacoleo . The first rodents arrived in Australia. The modern platypus ,
9504-765: The park are the Barrytown syncline , the Punakaiki anticline , the Paparoa Tectonic Zone, the Cape Foulwind fault and the Hawera fault. Most of the land area of the park is mountainous. The eastern side of the main range has deep glaciated valleys that run north and south, with towering bluffs and cirques , hanging valleys, and truncated spurs . The western coastline is known for its spectacular and varied scenery and its accessibility. The Paparoa mountains were uplifted during
9612-892: The park range from on or near the coastline to the peak of the Paparoa Ranges. Several species such as tūī , bellbird, kākā , kererū (New Zealand pigeon) and parakeets migrate from winter habitat in the lower forests to summer habitat in the upland forests. A significant feature of the coast is the colony of the rare seabird, the Westland petrel (tāiko), that is located on densely forested terraces just south of Punakaiki river. The Westland petrel breeding site at Punakaiki has been identified as an Important Bird Area by BirdLife International . Large colonies of New Zealand fur seals have been established adjacent areas around Westport such as at Cape Foulwind . Rare southern elephant seals and leopard seals also visit. Hector's dolphins (some of
9720-596: The provincial government provisions were implemented. Early in 1848 Edward John Eyre was appointed Lieutenant-Governor of New Munster. The Provincial Council of New Munster had only one legislative session, in 1849, before it succumbed to the virulent attacks of settlers from Wellington . Governor Sir George Grey , sensible to the pressures, inspired an ordinance of the General Legislative Council under which new Legislative Councils would be established in each province with two-thirds of their members elected on
9828-776: The reorganisation of the Indonesian Throughflow. In the south-central Andes , an arid period occurred from 6.1 to 5.2 Ma, with another occurring from 3.6 to 3.3 Ma. These arid periods are coincident with global cold periods, during which the position of the Southern Hemisphere westerlies shifted northward and disrupted the South American Low Level Jet, which brings moisture to southeastern South America. From around 3.8 Ma to about 3.3 Ma, North Africa experienced an extended humid period. In northwestern Africa, tropical forests extended up to Cape Blanc during
9936-518: The scene. Bears, dogs and weasels (originally from North America) joined cats, hyenas and civets as the African predators, forcing hyenas to adapt as specialized scavengers. Most mustelids in Africa declined as a result of increased competition from the new predators, although Enhydriodon omoensis remained an unusually successful terrestrial predator. South America was invaded by North American species for
10044-406: The southwest, than to the relatively nearby main range of the Southern Alps . Rivers flowing from the Paparoa Ranges pass through the limestone syncline, creating subterranean waterways and extensive cave systems that are one of the features of the park. The main rivers are the Fox , Pororari and Punakaiki . Another of the rivers is Cave Creek, site of the 1995 Cave Creek disaster . Cave Creek
10152-546: The summer of 1831–32 Te Rauparaha attacked the Kaiapoi pā (fortified village). Kaiapoi was engaged in a three-month siege by Te Rauparaha, during which his men successfully sapped the pā. They then attacked Kāi Tahu on Banks Peninsula and took the pā at Onawe . In 1832–33 Kāi Tahu retaliated under the leadership of Tūhawaiki and others, attacking Ngāti Toa at Lake Grassmere . Kāi Tahu prevailed, and killed many Ngāti Toa, although Te Rauparaha again escaped. Fighting continued for
10260-400: The surrounding environment. Anthropologists tended to focus on intrinsic models while geologists and vertebrate paleontologists tended to put greater emphasis on habitats. Alternatives to the savanna hypothesis include the woodland/forest hypothesis, which emphasizes the evolution of hominins in closed habitats, or hypotheses emphasizing the influence of colder habitats at higher latitudes or
10368-437: The syncline with more recent gravels and mudstones occupying the low-lying area in between. These more easily erodible rocks overlie interstratal karst. The majority of known cave systems are in the western side of the limestone syncline where underground drainage patterns are concentrated mainly along horizontal lines of weakness in the bedding planes . The Paparoa coastline is characterised by high cliffs cut away by waves from
10476-649: The time Europeans arrived, local Māori did not know the origins of the drawings. Early inhabitants of the South Island were the Waitaha . They were largely absorbed via marriage and conquest by the Kāti Māmoe in the 16th century. Kāti Māmoe were in turn largely absorbed via marriage and conquest by the Kāi Tahu who migrated south in the 17th century. While today there is no distinct Kāti Māmoe organisation, many Kāi Tahu have Kāti Māmoe links in their whakapapa and especially in
10584-430: The two main islands of New Zealand are called the North Island and the South Island , with the definite article . It is also normal to use the preposition in rather than on , for example "Christchurch is in the South Island", "my mother lives in the South Island". Maps, headings, tables, and adjectival expressions use South Island without "the". As it is 32% larger than the North Island but contains less than
10692-718: The well-prepared Kāi Tahu killed all the leading Ngāti Toa chiefs except Te Rauparaha. Te Rauparaha returned to his Kapiti Island stronghold. In November 1830, Te Rauparaha persuaded Captain John Stewart of the brig Elizabeth to carry him and his warriors in secret to Akaroa , whereby in subterfuge they captured the leading Kāi Tahu chief, Tama-i-hara-nui , and his wife and daughter. After destroying Tama-i-hara-nui's village, they took their captives to Kapiti and killed them. John Stewart, though arrested and sent to trial in Sydney as an accomplice to murder, nevertheless escaped conviction. In
10800-495: The west. This condition has been described as a permanent El Niño state, or “El Padre.” Several mechanisms have been proposed for this pattern, including increased tropical cyclone activity . The extent of the West Antarctic Ice Sheet oscillated at the 40 kyr period of Earth's obliquity. Ice sheet collapse occurred when the global average temperature was 3 °C warmer than today and carbon dioxide concentration
10908-506: Was at 400 ppmv. This resulted in open waters in the Ross Sea . Global sea-level fluctuation associated with ice-sheet collapse was probably up to 7 meters for the west Antarctic and 3 meters for the east Antarctic. Model simulations are consistent with reconstructed ice-sheet oscillations and suggest a progression from a smaller to a larger West Antarctic ice sheet in the last 5 million years. Intervals of ice sheet collapse were much more common in
11016-480: Was dominated by hoofed animals, and primates continued their evolution, with australopithecines (some of the first hominins ) and baboon-like monkeys such as the Dinopithecus appearing in the late Pliocene. Rodents were successful, and elephant populations increased. Cows and antelopes continued diversification and overtook pigs in numbers of species. Early giraffes appeared. Horses and modern rhinos came onto
11124-477: Was ephemeral before the onset of extensive glaciation over Greenland that occurred in the late Pliocene around 3 Ma. The formation of an Arctic ice cap is signaled by an abrupt shift in oxygen isotope ratios and ice-rafted cobbles in the North Atlantic and North Pacific Ocean beds. Mid-latitude glaciation was probably underway before the end of the epoch. The global cooling that occurred during
11232-452: Was first flooded near the start of the Pliocene, allowing marine organisms to spread between the Arctic and Pacific Oceans. The bridge would continue to be periodically flooded and restored thereafter. Pliocene marine formations are exposed in northeast Spain , southern California , New Zealand , and Italy . During the Pliocene parts of southern Norway and southern Sweden that had been near sea level rose. In Norway this rise elevated
11340-508: Was generally peaceful. In 1861, gold was discovered at Gabriel's Gully in Central Otago , sparking a gold rush . Dunedin became the wealthiest city in the country, and many in the South Island resented financing the North Island's wars. In the 1860s, several thousand Chinese men, mostly from the Guangdong province, migrated to New Zealand to work on the South Island goldfields. Although
11448-525: Was not to be used in the future. "South Island will be adhered to in all cases". Although the island had been known as the South Island for many years, in 2009 the New Zealand Geographic Board found that along with the North Island, the South Island had no official name. After a public consultation, the board officially named the island South Island or Te Waipounamu in October 2013. In prose,
11556-505: Was set at the start of the Pleistocene glaciations. Charles Lyell (later Sir Charles) gave the Pliocene its name in Principles of Geology (volume 3, 1833). The word pliocene comes from the Greek words πλεῖον ( pleion , "more") and καινός ( kainos , "new" or "recent") and means roughly "continuation of the recent", referring to the essentially modern marine mollusc fauna. In
11664-541: Was very similar to what it is today. Unexpectedly, the expansion of grasslands in eastern Africa during this epoch appears to have been decoupled from aridification and not caused by it, as evidenced by their asynchrony. Southwestern Australia hosted heathlands , shrublands , and woodlands with a greater species diversity compared to today during the Middle and Late Pliocene. Three different aridification events occurred around 2.90, 2.59, and 2.56 Ma, and may have been linked to
