Peat is an accumulation of partially decayed vegetation or organic matter . It is unique to natural areas called peatlands , bogs , mires , moors , or muskegs . Sphagnum moss, also called peat moss, is one of the most common components in peat, although many other plants can contribute. The biological features of sphagnum mosses act to create a habitat aiding peat formation, a phenomenon termed 'habitat manipulation'. Soils consisting primarily of peat are known as histosols . Peat forms in wetland conditions, where flooding or stagnant water obstructs the flow of oxygen from the atmosphere, slowing the rate of decomposition. Peat properties such as organic matter content and saturated hydraulic conductivity can exhibit high spatial heterogeneity .

105-575: The Waikato ( / ˈ w aɪ k ɑː t ɔː / ) is a region of the upper North Island of New Zealand. It covers the Waikato District , Waipa District , Matamata-Piako District , South Waikato District and Hamilton City , as well as Hauraki , Coromandel Peninsula , the northern King Country , much of the Taupō District , and parts of the Rotorua Lakes District . It is governed by

210-490: A local government reform in 1989 that took place under the Local Government Act 1974 . The regional councils replaced the more than 700 ad hoc bodies that had been formed in the preceding century – roads boards, catchment boards, drainage boards, pest control boards, harbour boards, domain and reserve boards. In addition they took over some roles that had previously been performed by county councils. The boundaries of

315-506: A form of erosion that occur at the sides of gullies that cut into the peat; they sometimes also occur in isolation. Hags may result when flowing water cuts downwards into the peat and when fire or overgrazing exposes the peat surface. Once the peat is exposed in these ways, it is prone to further erosion by wind, water and livestock. The result is overhanging vegetation and peat. Hags are too steep and unstable for vegetation to establish itself, so they continue to erode unless restorative action

420-551: A much wider variety of food from the Thames area. Missionaries had also established schools for Māori. Benjamin and Harriet Ashwell ran a school for 50 Māori girls aged 6–17 at Taupiri in 1853. The girls had been at the school for up to 3 years and could read and write in English and do mental arithmetic. At the time of the Waikato campaign of 1863 against the rebel Māori King Movement forces,

525-584: A number of hapū and iwi . The largest battle ever fought in New Zealand took place near Ohaupo about 1790–1805, between two competing alliances of hapū . During the latter stages of this volatile period, known as the Musket Wars (1807–1845), conflict led to a migration south to Taranaki and eventually Kapiti Island. In 1840 44 Waikato chiefs travelled north to the Manukau Heads and Manukau Harbour to sign

630-496: A result of peat drainage, the organic carbon—which built over thousands of years and is normally underwater—is suddenly exposed to the air. It decomposes and turns into carbon dioxide (CO 2 ), which is released into the atmosphere. The global CO 2 emissions from drained peatlands have increased from 1,058 Mton in 1990 to 1,298 Mton in 2008 (a 20% increase). This increase has particularly taken place in developing countries, of which Indonesia , Malaysia and Papua New Guinea are

735-970: A separate kingdom – the King Movement or Kingitanga – in opposition to the government, the colonial government, with the help of troops brought from Britain and Queenite Māori loyal to the Crown, pushed south from the main settlement of Auckland , fighting against Waikato raiders in Auckland before venturing into the Waikato to attack the combined hapu of the King Movement. During 1863 and 1864 fighting occurred at Pukekohe East, Titi hill, Burtts Farm, Galloway Redoubt, Kiri Kiri, Martyn's Farm, Patumahoe, Rhodes Clearing, Williamson's Clearing, Otau, Camerontown, Kakaramea and Wairoa ranges (all Auckland), Meremere , Rangiriri, Ngāruawāhia, Rangiaowhia (southwest of Cambridge), Hairini Ridge and Ōrākau (near Kihikihi), all resulting in defeat for

840-490: A small increase in carbon dioxide uptake, meaning that it contributes to the permafrost carbon feedback . Under 2 °C global warming , 0.7 million km of peatland permafrost could thaw, and with warming of +1.5 to 6 °C a cumulative 0.7 to 3 PgC of methane could be released as a result of permafrost peatland thaw by 2100. The forcing from these potential emissions would be approximately equivalent to 1% of projected anthropogenic emissions. One characteristic of peat

945-509: A smaller region than the Waikato local government region. Two definitions that would meet with wide acceptance are those of the Waikato rugby football union and of Hamilton Waikato tourism. To the west, the region is bounded by the Tasman Sea . The coastal region is largely rough hill country, known locally as the Hakarimata Range , though it is more gently undulating in the north, closer to

1050-539: A tenth of the total permafrost area, and also a tenth (185 ± 66 Gt) of all permafrost carbon, equivalent to around half of the carbon stored in the atmosphere. Dry peat is a good insulator (with a thermal conductivity of around 0.25 Wm K ) and therefore plays an important role in protecting permafrost from thaw. The insulating effect of dry peat also makes it integral to unique permafrost landforms such as palsas and permafrost peat plateaus. Peatland permafrost thaw tends to result in an increase in methane emissions and

1155-448: A variety of supplementary feeds in winter or during the infrequent summer droughts. Main feeds are hay, grass silage and chopped corn feed. The later is often fed out on a concrete pad to save transportation and wastage by trampling. The manufacturing sector in Waikato contributed $ 2,688 million in GDP in the year to March 2018, 11.1% of the regional GDP. According to the 2013 New Zealand census,

1260-479: A well-educated government agent, reported significant numbers of half-caste children in the Waikato in the late 1850s. However, in the Ngati Maniapoto iwi at least 7 Pakeha integrated successfully with the tribe from 1842, marrying Maori women. The best known are William Searancke, who became an important government agent, and Frenchman Louis Hetet, who became a successful trader. Their half-caste children lived with

1365-425: Is a mixture of elected councillors and government appointed commissioners. Councils may use a first-past-the-post or single transferable vote system. The chairperson is selected by the elected council members. Regional councils are funded through property rates , subsidies from central government, income from trading, and user charges for certain public services. Councils set their own levels of rates, though

1470-487: Is also reported that peat regrowth takes place only in 30–40% of peatlands. Centuries of burning and draining of peat by humans has released a significant amount of CO 2 into the atmosphere, and much peatland restoration is needed to help limit climate change . Peat forms when plant material does not fully decay in acidic and anaerobic conditions. It is composed mainly of wetland vegetation: principally bog plants including mosses , sedges and shrubs. As it accumulates,

1575-472: Is available in considerable quantities. It is burned to produce heat and electricity . Peat provides around 4% of Finland's annual energy production. Also, agricultural and forestry-drained peat bogs actively release more CO 2 annually than is released in peat energy production in Finland. The average regrowth rate of a single peat bog, however, is indeed slow, from 1,000 up to 5,000 years. Furthermore, it

1680-423: Is bounded by Auckland on the north, Bay of Plenty on the east, Hawke's Bay on the south-east, and Manawatū-Whanganui and Taranaki on the south. Waikato Region is the fourth largest region in the country in area and population: It has a land area of 23,901.09 km (9,228.26 sq mi) and a population of 536,200 (June 2024). The region encompasses all or part of eleven territorial authorities ,

1785-547: Is cut by hand and left to dry in the sun. In many countries, including Ireland and Scotland , peat was traditionally stacked to dry in rural areas and used for cooking and domestic heating. This tradition can be traced back to the Roman period. For industrial uses, companies may use pressure to extract water from the peat, which is soft and easily compressed. In Sweden, farmers use dried peat to absorb excrement from cattle that are wintered indoors. The most essential property of peat

1890-423: Is either fibric, hemic, or sapric. Fibric peats are the least decomposed and consist of intact fibre. Hemic peats are partially decomposed and sapric are the most decomposed. Phragmites peat are composed of reed grass, Phragmites australis , and other grasses. It is denser than many other types of peat. Engineers may describe a soil as peat which has a relatively high percentage of organic material. This soil

1995-701: Is estimated that in 1997, peat and forest fires in Indonesia released between 0.81 and 2.57 gigatonnes (0.89 and 2.83 billion short tons; 0.80 and 2.53 billion long tons) of carbon; equivalent to 13–40 percent of the amount released by global fossil fuel burning, and greater than the carbon uptake of the world's biosphere. These fires may be responsible for the acceleration in the increase in carbon dioxide levels since 1998. More than 100 peat fires in Kalimantan and East Sumatra have continued to burn since 1997; each year, these peat fires ignite new forest fires above

2100-483: Is problematic because it exhibits poor consolidation properties—it cannot be easily compacted to serve as a stable foundation to support loads, such as roads or buildings. In a widely cited article, Joosten and Clarke (2002) described peatlands or mires (which they say are the same) as the most widespread of all wetland types in the world, representing 50 to 70% of global wetlands. They cover over 4 million square kilometres [1.5 million square miles] or 3% of

2205-497: Is retaining moisture in container soil when it is dry while preventing the excess water from killing roots when it is wet. Peat can store nutrients although it is not fertile itself—it is polyelectrolytic with a high ion-exchange capacity due to its oxidized lignin. Peat is discouraged as a soil amendment by the Royal Botanic Gardens, Kew , England, since 2003. While bark or coir -based peat-free potting soil mixes are on

2310-629: Is sometimes used in freshwater aquaria . It is seen most commonly in soft water or blackwater river systems such as those mimicking the Amazon River basin. In addition to being soft and therefore suitable for demersal (bottom-dwelling) species such as Corydoras catfish, peat is reported to have many other beneficial functions in freshwater aquaria. It softens water by acting as an ion exchanger ; it also contains substances that are beneficial for plants and fishes' reproductive health. Peat can prevent algae growth and kill microorganisms. Peat often stains

2415-722: Is taken. In June 2002, the United Nations Development Programme launched the Wetlands Ecosystem and Tropical Peat Swamp Forest Rehabilitation Project. This project was targeted to last for five years, and brings together the efforts of various non-government organisations. In November 2002, the International Peatland (formerly Peat) Society (IPS) and the International Mire Conservation Group (IMCG) published guidelines on

2520-565: Is the average depth of the boreal [northern] peatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO 2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon , which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. Peat is not a renewable source of energy , due to its extraction rate in industrialized countries far exceeding its slow regrowth rate of 1 mm (0.04 in) per year, and as it

2625-401: Is the bioaccumulation of metals concentrated in the peat. Accumulated mercury is of significant environmental concern. Large areas of organic wetland (peat) soils are currently drained for agriculture, forestry and peat extraction (i.e. through canals ). This process is taking place all over the world. This not only destroys the habitat of many species but also heavily fuels climate change. As

2730-457: Is the low average wind speed in the interior basin due to the sheltering influence of the hills and mountains to the west and south-west. The prevailing winter wind is from the south-west. The Waikato has very high sunshine hours by world standards, averaging 2200 hours per year or about 40% higher than in the UK. This results in rapid growth of grass, crops and ornamental plants. Hamilton Waikato takes in

2835-407: Is the most efficient carbon sink on the planet , because peatland plants capture carbon dioxide (CO 2 ) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of 1.5 to 2.3 m [4.9 to 7.5 ft], which

2940-453: The "Wise Use of Mires and Peatlands – Backgrounds and Principles including a framework for decision-making" . This publication aims to develop mechanisms that can balance the conflicting demands on the global peatland heritage to ensure its wise use to meet the needs of humankind. In June 2008, the IPS published the book Peatlands and Climate Change , summarising the currently available knowledge on

3045-803: The 2018 census , and an increase of 95,130 people (23.6%) since the 2013 census . There were 246,723 males, 250,380 females and 1,671 people of other genders in 180,006 dwellings. 2.8% of people identified as LGBTIQ+ . The median age was 37.9 years (compared with 38.1 years nationally). There were 100,743 people (20.2%) aged under 15 years, 93,111 (18.7%) aged 15 to 29, 218,808 (43.9%) aged 30 to 64, and 86,109 (17.3%) aged 65 or older. People could identify as more than one ethnicity. The results were 71.7% European ( Pākehā ); 25.2% Māori ; 5.2% Pasifika ; 12.2% Asian ; 1.4% Middle Eastern, Latin American and African New Zealanders (MELAA); and 2.3% other, which includes people giving their ethnicity as "New Zealander".

3150-630: The Chiefs Super Rugby team and Waikato Mitre 10 Cup rugby team at Waikato Stadium and the Northern Districts Knights in domestic cricket at Seddon Park , both in Hamilton. Regions of New Zealand New Zealand is divided into sixteen regions for local government purposes. Eleven are administered by regional councils, and five are administered by unitary authorities , which are territorial authorities that also perform

3255-805: The Falkland Islands and Indonesia ( Kalimantan [Sungai Putri, Danau Siawan, Sungai Tolak], Rasau Jaya ( West Kalimantan ) and Sumatra ). Indonesia has more tropical peatlands and mangrove forests than any other nation on earth, but Indonesia is losing wetlands by 100,000 hectares (250,000 acres) per year. A catalog of the peat research collection at the University of Minnesota Duluth provides references to research on worldwide peat and peatlands. About 7% of all peatlands have been exploited for agriculture and forestry . Under certain conditions, peat will turn into lignite coal over geologic periods of time. Peat can be used as fuel once dried. Traditionally, peat

3360-800: The Kingitanga forces. Eventually the rebel King Movement forces pulled back to positions in the area to the south of the Punui River in South Waikato, still known as the King Country , after 19 defeats by the British. Rewi's Last Stand , one of New Zealand's first motion pictures, in 1925, portrayed an entertaining, fictionalized version of the Ōrākau siege. The headquarters of the Māori King Movement are now at Turangawaewae Marae at Ngāruawāhia . After

(2) The Gisborne Region is still widely but unofficially known by its former name East Cape or as the East Coast. Some outlying islands are not included within regional boundaries. The Chatham Islands is not in a region, although its council has some of

3570-865: The Tongariro , on the Central Plateau , draining the eastern side of Mount Ruapehu and its neighbours. The climate is mild and temperate with moderate rainfall of 1,200 to 1,600 mm (47 to 63 in) per annum, with the higher western hills having the most rain. Summers are drier with typical maximum temperatures of 22–28 degrees Celsius and overnight lows of 12–16 degrees. Summer droughts occur one year in ten. Typical winter maxima are 10–16 degrees Celsius, with lows generally ranging from 0–8 degrees. Depressions experience regular morning fog, under anticyclonic conditions, which burns off by late morning to produce many still, clear sunny days. Morning frosts are also common during winter anticyclones. Another distinctive feature

3675-763: The Waikato Catchment Board . The Waikato United Council , was formulated under the Local Government Act 1974 , but due to objections excluded Thames/Coromandel district, though otherwise covered the present extent of the region. It was set up under the Town and Country Planning Act 1977 and the Waikato Region Constitution Order 1980. WUC covered Hamilton City , Huntly , Ngāruawāhia , Cambridge , Te Awamutu , Matamata , Putāruru and Tokoroa boroughs, Matamata , Raglan , Waikato , and Waipa counties, Ōtorohanga and Waitomo districts. It took over

3780-933: The West Siberian Lowland , the Hudson Bay Lowlands and the Mackenzie River Valley. There is less peat in the Southern Hemisphere, in part because there is less land. The world's largest tropical peatland is located in Africa (the Democratic Republic of Congo). In addition, the vast Magellanic Moorland in South America (Southern Patagonia / Tierra del Fuego ) is an extensive peat-dominated landscape. Peat can be found in New Zealand , Kerguelen ,

Having been discovered in 1950 after being mistaken for a recent murder victim, he was exhumed for scientific purposes and dated to have lived during the 4th century BC. Before that, another bog body, the Elling Woman , had been discovered in 1938 in

After 1900, dairy production in the Waikato continued to grow, exporting butter and cheese mainly to Britain. Following major floods in 1907, a Waikato River Board was formed in 1911. However, it was reported as ineffective in 1921 and ceased to operate, though

4095-630: The Hamilton Regional Planning Authority and mainly dealt with regional planning and civil defence. By 1989, WUC had committees for regional planning, civil defence, regional government, and the Waikato Regional Development Board. From 1987 it also included Thames-Coromandel District , Great Barrier Island , Hauraki Plains , Ohinemuri and Piako counties, and Morrinsville , Paeroa , Te Aroha and Waihi boroughs. On 1 November 1989, Waikato Regional Council

4200-768: The Kihikihi area by the introduction of such crops as peaches, maize and wheat. Missionaries brought in millers and helped Māori establish eight flour mills. These flourished until 1857, as they provided flour for the growing Auckland market in the 1850s and for a brief while were exporting to Australia. There were mills at Aotea , Kaitotehe , Karakariki, Kihikihi , Kirikiriroa , Kohanga, Kopatauaki, Mahoe , Mangaharakeke, Mangapapa, Mangarewarewa, Mangatawhiri , Matamata pā, Maungakawa , Maungatautari , Mohoaonui, Otawhao, Patetere, Rangataiki, Rangiaowhia , Taupō, Te Kopua, Te Rore , Tireke, Tuakau , Waitetuna , Whaingaroa and Whatawhata .

4305-652: The Treaty of Waitangi, officially making the Waikato area part of New Zealand. Three Ngāti Maniapoto chiefs signed, as did three Ngāti Haua chiefs but most signatories were Waikato. Chief Te Whero whero did not sign, "probably due to the lack of dignity compared to the Waitangi event". Unusually, the copy signed was in English. Between 1840 and 1860 the CMS missionaries of the Anglican church assisted Waikato Māori in revolutionising their economy in

4410-491: The Waikato Region increased by 5 per cent per year compared with 3.2 per cent for the national average. This faster growth can be attributed to rapidly growing dairy and business services industries, facilitated by proximity to the Auckland city, the main international gateway for New Zealand. Given the suitable geography and climate, the Waikato economy is strongly based on agriculture, especially dairy. Dairy farming has been

4515-670: The Waikato Regional Council. The Waikato stretches from Coromandel Peninsula in the north, to the north-eastern slopes of Mount Ruapehu in the south, and spans the North Island from the west coast, through the Waikato and Hauraki to Coromandel Peninsula on the east coast. Broadly, the extent of the region is the Waikato River catchment. Other major catchments are those of the Waihou , Piako , Awakino and Mokau rivers. The region

4620-457: The Waikato River are used for hydroelectricity , helped by several large artificial lakes in the region's south-east. The lowest and earliest-created such lake is Lake Karapiro , now developed as a world-class rowing centre, where the world championships were held in 2010. The river flows out of the country's largest lake, Lake Taupō , which is served by several important fishing rivers such as

4725-422: The Waikato use the nickname Mooloo to apply to themselves or to their region, particularly in relation to sporting endeavours. The word was likely first applied to the Waikato provincial rugby team . Its origin is related to the mascot of a pantomime-like milking cow used in parades, public events and sports matches — particularly rugby, reflecting the importance of the dairy industry to the region. Waikato hosts

4830-537: The West Siberian peatland. Palsa mires have a rich bird life and are an EU-red listed habitat, and in Canada riparian peat banks are used as maternity sites for polar bears. Natural peatlands also have many species of wild orchids and carnivorous plants. For more on biological communities, see wetland , bog or fen . Around half of the area of northern peatlands is permafrost -affected, and this area represents around

4935-555: The average dairy herd in the Waikato has progressively increased. It was about 320 cows in 2012 and in 2016 was about 351 (total Waikato herd 1.41m cows), milked in either a herringbone or automated rotary cowshed so a large herd can be milked in under two hours. The cows are kept on grassland pasture all year due to the mild climate. In the Waikato the original English grasses used by earlier settlers – browntop , fescue and Yorkshire Fog – have been replaced with higher producing Italian ryegrass and nitrogen-fixing white clover. Farmers use

5040-522: The bogland remains constantly wet which helps promote peat production. Most modern peat bogs formed 12,000 years ago in high latitudes after the glaciers retreated at the end of the last ice age . Peat usually accumulates slowly at the rate of about a millimetre per year. The estimated carbon content is 415 gigatonnes (457 billion short tons) (northern peatlands), 50 Gt (55 billion short tons) ( tropical peatlands ) and 15 Gt (17 billion short tons) (South America). Peat material

5145-546: The capital of Moscow with a toxic smoke blanket . The situation remained critical until the end of August 2010. In June 2019, despite some forest fire prevention methods being put in place, peat fires in the Arctic emitted 50 megatonnes (55 million short tons; 49 million long tons) of CO 2 , which is equal to Sweden's total annual emissions. The peat fires are linked to climate change, as they are much more likely to occur nowadays due to this effect. Peat "hags" are

5250-427: The census question. Of those at least 15 years old, 65,295 (16.4%) people had a bachelor's or higher degree, 212,241 (53.3%) had a post-high school certificate or diploma, and 101,277 (25.4%) people exclusively held high school qualifications. The median income was $ 40,300, compared with $ 41,500 nationally. 40,746 people (10.2%) earned over $ 100,000 compared to 12.1% nationally. The employment status of those at least 15

During the land wars of the 1860s, the Waikato was the scene of five battles in what is referred to as the Invasion of the Waikato . In retaliation for the help Waikato Māori (mainly Ngāti Maniapoto ) gave Taranaki Māori in their conflict over land in the earlier First Taranaki War , and the decision by some Waikato hapu to form

5460-428: The concept of peat archives, a phrase coined by influential peatland scientist Harry Godwin in 1981. In a peat profile there is a fossilized record of changes over time in the vegetation, pollen, spores, animals (from microscopic to the giant elk), and archaeological remains that have been deposited in place, as well as pollen, spores and particles brought in by wind and weather. These remains are collectively termed

5565-532: The elevation of the first Māori king there was a wide range of opinions among influential Māori with some such as Wirimu Tamihana's father advocating supporting the Crown while Te Heuheu of Tuwharetoa advocated all out war against the government. This view was initially unpopular as the king movement hoped to work alongside the crown. Māori were upset at the number of children that had been fathered by Pakeha, who had then disappeared. The children were left to be raised by their mothers with general hapu support. John Gorst,

5670-521: The end of the Australian gold rush, allowing importing of cheaper food, especially flour, from Australia. Even in the boom time of 1854–55, food grown by Waikato Māori, such as Ngāti Maniapoto, was taken to the Auckland market in very small amounts compared to food from the Waiheke Island -Thames area. In early 1855 Ngāti Maniapoto took only 3 canoes of potatoes to Auckland compared to 279 canoes containing

5775-618: The end of the war and the withdrawal of British and Australian troops, the region experienced a long period of economic recession after 1866. Most Māori had moved to the King Country and European settlers were more attracted to the South Island with its large gold discovery in Otago and the more easily farmed Canterbury Plains. The Waikato had poor land access and was not suitable for sheep farming which dominated livestock production in New Zealand until

5880-452: The fastest-growing top emitters. This estimate excludes emissions from peat fires (conservative estimates amount to at least 4,000 Mton/CO 2 -eq./yr for south-east Asia). With 174 Mton/CO 2 -eq./yr, the EU is after Indonesia (500 Mton) and before Russia (161 Mton), the world's second-largest emitter of drainage-related peatland CO 2 (excl. extracted peat and fires). Total CO 2 emissions from

5985-679: The functions of regional councils. The Chatham Islands Council is not a region but is similar to a unitary authority, authorised under its own legislation. The regional councils are listed in Part 1 of Schedule 2 of the Local Government Act 2002 , along with reference to the Gazette notices that established them in 1989. The Act requires regional councils to promote sustainable development  – the social, economic, environmental and cultural well-being of their communities. The current regions and most of their councils came into being through

6090-406: The government's expense. This upset the older chiefs, who wanted the strong Māori leader Te Wherowhero to return from Mangere to his lands at Tamahere (South Hamilton) to rein in the out-of-control young chief magistrates. The Waikato has a prominent history, particularly regarding relationships between Māori and European in early colonial New Zealand. The Waikato was within the defined boundaries of

6195-596: The ground. In North America, peat fires can occur during severe droughts throughout their occurrence, from boreal forests in Canada to swamps and fens in the subtropical southern Florida Everglades . Once a fire has burnt through the area, hollows in the peat are burnt out, and hummocks are desiccated but can contribute to Sphagnum recolonization. In the summer of 2010, an unusually high heat wave of up to 40 °C (104 °F) ignited large deposits of peat in Central Russia, burning thousands of houses and covering

6300-453: The hillier west margins, and crops such as maize. The area around Cambridge has many thoroughbred stables. The north of the region around Te Kauwhata produces some of New Zealand's best wines. Dozens of small shallow lakes lie in this area, the largest of which is Lake Waikare . To the east, the land rises towards the forested slopes of the Kaimai and Mamaku Ranges . The upper reaches of

6405-448: The iwi, and some became leading figures. What tipped the balance was conflict and criminal activity within the Waikato region. Influential chiefs said the treaty had promised the government would help maintain peace. They asked for government magistrates and courts. The government attempted to fulfil these requests but many of the young men who put themselves forward for the positions simply saw that they had an opportunity to get wealthy at

These ecosystems are characterized by the unique ability to accumulate and store dead organic matter from Sphagnum and many other non-moss species, as peat, under conditions of almost permanent water saturation. Peatlands are adapted to the extreme conditions of high water and low oxygen content, of toxic elements and low availability of plant nutrients. Their water chemistry varies from alkaline to acidic. Peatlands occur on all continents, from

It is in the broad undulating Waikato Plains that most of the region's population resides, and the land is intensively farmed with both livestock, mainly dairy cattle but with sheep farming on

6720-415: The legislation were coordination of civil defence and development of a regional plan, although the constituent TLAs could agree on additional responsibilities at the point of formation of each united council. For example, in a number of cases the united council took responsibility for the allocation of revenue from regional petrol taxes. The united councils were based in the facilities of the largest TLA in

6825-537: The local government areas of Hamilton City, the southern part of Waikato district, Waipa district, most of Matamata-Piako district and the South Waikato district. Hamilton Waikato tourism takes in additionally the northern part of Waikato district (Tuakau and other centres), the northern King Country (Waitomo and Ōtorohanga districts), and the Te Aroha district. The parts of Waikato region beyond these limits are usually identified as Thames Valley and/or Hauraki/Coromandel (for

6930-682: The main agricultural activity since the late nineteenth century. Within the Waikato region, small co-operative dairy companies were widespread during the 20th century. Towards the end of the 20th century, frequent mergers of co-operative dairy companies occurred, which ultimately ended in the formation of New Zealand wide dairy co-operative Fonterra in 2001. In 2007, dairy farming and dairy processing combined contributed $ 2 billion (13%) to GRP, which had risen to $ 2.4bn by 2014, but only 13,683 (7.6%) of jobs in 2016. Dairy farms are mainly family owned (2,608 of 4,020 farms in 2016) with owners employing sharemilkers in many cases (1,412 sharemilkers). The size of

7035-501: The main source of water for large cities, including Dublin. Peat wetlands also used to have a degree of metallurgical importance in the Early Middle Ages , being the primary source of bog iron used to create swords and armour. Many peat swamps along the coast of Malaysia serve as a natural means of flood mitigation, with any overflow being absorbed by the peat, provided forests are still present to prevent peat fires. Peat

7140-731: The mechanism for collecting it usually involves channelling through the territorial authority collection system. The Auckland Regional Council (now the Auckland Council ) was preceded by the Auckland Regional Authority (ARA), which existed from 1963 to 1989. The Wellington Regional Council was first formed in 1980 from a merger of the Wellington Regional Planning Authority and the Wellington Regional Water Board. In 1978, legislation

7245-541: The most of any region of New Zealand. It is centred on the Waikato which consists of Waikato District , Matamata-Piako District , Waipa District , South Waikato District and Hamilton City . In descending order of land area the eleven territorial authorities are Taupō District (part), Waikato District, Waitomo District (part), Thames-Coromandel District , Ōtorohanga District , South Waikato District, Matamata-Piako District, Waipa District, Hauraki District , Rotorua Lakes District (part), and Hamilton City. The name for

7350-419: The mouth of the Waikato River. The coast is punctured by three large natural harbours: Raglan Harbour , Aotea Harbour , and Kawhia Harbour . The area around Raglan is noted for its volcanic black sand beaches and for its fine surfing conditions at Manu Bay and Ruapuke beach. To the east of the coastal hills lies the broad alluvial plain of the Waikato River. This region has a wet temperate climate, and

7455-512: The need for a replacement was considered in 1933. Hauraki Catchment Board was set up in 1946. Major floods also occurred in 1953 and 1956. Waikato Valley Authority was established by the Waikato Valley Authority Act on 26 October 1956. The Water and Soil Conservation Act 1967 extended it to become a Catchment/Regional Water Board. The Ministry of Works and Development Abolition Act 1988, left WVA with that work and it became

7560-479: The north-eastern part of Waikato region) and Taupō, on the Volcanic or Central Plateau (for the south-eastern part of the region). Waikato Region covers 23,900.95 km (9,228.21 sq mi) and had an estimated population of 536,200 as of June 2024, with a population density of 22 people per km. Waikato Region had a population of 498,771 in the 2023 New Zealand census , an increase of 40,569 people (8.9%) since

7665-540: The peat archives. In Quaternary Palaeoecology , first published in 1980, Birks and Birks described how paleoecological studies "of peat can be used to reveal what plant communities were present (locally and regionally), what period each community occupied, how environmental conditions changed, and how the environment affected the ecosystem in that time and place." Scientists continue to compare modern mercury (Hg) accumulation rates in bogs with historical natural archives records in peat bogs and lake sediments to estimate

7770-433: The peat holds water. This slowly creates wetter conditions that allow the area of wetland to expand. Peatland features can include ponds, ridges and raised bogs . The characteristics of some bog plants actively promote bog formation. For example, sphagnum mosses actively secrete tannins , which preserve organic material. Sphagnum also have special water-retaining cells, known as hyaline cells, which can release water ensuring

7875-554: The population was estimated by the government at about 3,500 Māori. During the late 1850s Maniapoto in particular become disgruntled in their dealings with Pakeha. They complained about the way they were treated in Auckland by traders but their chief complaint was that the government was underpaying them for land they were selling. The average price paid by government was 6d per acre but it was sold to settlers for 10/- per acre. The government argued that it had to pay for surveying and administration costs but to Māori it seemed unfair. Before

7980-678: The potential human impacts on the biogeochemical cycle of mercury, for example. Over the years, different dating models and technologies for measuring date sediments and peat profiles accumulated over the last 100–150 years, have been used, including the widely used vertical distribution of 210Pb, the inductively coupled plasma mass spectrometry (ICP-SMS), and more recently the initial penetration (IP). Naturally mummified human bodies, often called " bog bodies " have been found in various places in Scotland, England, Ireland, and especially northern Germany and Denmark. They are almost perfectly preserved by

8085-524: The powers of a regional council under the Resource Management Act 1991 . The Kermadecs and the subantarctic islands are inhabited only by a small number of Department of Conservation staff and there is no regional council for these islands. Regional councils are popularly elected every three years in accordance with the Local Electoral Act 2001, except for the Canterbury regional council, which

8190-441: The presence of a heat source (e.g., a wildfire penetrating the subsurface), it smoulders. These smouldering fires can burn undetected for very long periods of time (months, years, and even centuries) propagating in a creeping fashion through the underground peat layer. Despite the damage that the burning of raw peat can cause, bogs are naturally subject to wildfires and depend on the wildfires to keep woody competition from lowering

8295-447: The primary source of peat; although less common, other wetlands, including fens , pocosins and peat swamp forests , also deposit peat. Landscapes covered in peat are home to specific kinds of plants, including Sphagnum moss, ericaceous shrubs and sedges . Because organic matter accumulates over thousands of years, peat deposits provide records of past vegetation and climate by preserving plant remains, such as pollen. This allows

8400-545: The reconstruction of past environments and the study of land-use changes. Peat is used by gardeners and for horticulture in certain parts of the world, but this is being banned in some places. By volume, there are about 4 trillion cubic metres of peat in the world. Over time, the formation of peat is often the first step in the geological formation of fossil fuels such as coal , particularly low-grade coal such as lignite . The peatland ecosystem covers 3.7 million square kilometres (1.4 million square miles) and

8505-680: The region and largely dependent on the TLAs for resources. They were allowed to levy rates but in most cases had minimal operating budgets (below $ 100,000 per annum). The notable exception was Canterbury, where the united council had a number of responsibilities. Only one united council undertook any direct operational activity – a forestry project in Wanganui. Source: Summary of the Functions and Activities of United Councils . Dept of Internal Affairs, 1984. Peat Peatlands, particularly bogs , are

8610-411: The region is taken from the Waikato River ; waikato is a Māori word traditionally translated as "flowing water" (specifically, wai = "water" and kato = "the pull of the river current in the sea"). When Waikato is used in spoken language some people use it in the definite article , "the Waikato", whereas some people do not use "the". It is unknown why a difference is made. "The" usually refers to

8715-532: The regions are based largely on drainage basins . This anticipated the responsibilities of the Resource Management Act 1991 . Most regional boundaries conform with territorial authority boundaries but there are a number of exceptions. An example is Taupo District , split between four regions, although most of its area is in the Waikato region. There is often a high degree of co-operation between regional and territorial councils as they have complementary roles. Regional councils have these specific functions under

8820-614: The rewetting of peatlands and revegetation of native species. This acts to mitigate carbon release in the short term before the new growth of vegetation provides a new source of organic litter to fuel the peat formation in the long term. UNEP is supporting peatland restoration in Indonesia. Latvia has been the biggest exporter of peat in the world by volume, providing more than 19.9% of the world's volume, followed only by Canada with 13% in 2022. In 2020, Latvia exported 1.97 million tons of peat, followed by Germany with 1.5 and Canada with 1.42 million tons. Nevertheless, although first in

8925-565: The rise, particularly in the UK, peat is still used as raw material for horticulture in some other European countries, Canada, as well as parts of the United States. Peatland can also be an essential source of drinking water , providing nearly 4% of all potable water stored in reservoirs . In the UK, 43% of the population receives drinking water sourced from peatlands, with the number climbing to 68% in Ireland. Catchments containing peatlands are

9030-611: The same bog about 60 metres (200 ft) from the Tollund Man. She is believed to have lived during the late 3rd century BC and was a ritual sacrifice. In the Bronze and Iron Ages, people used peat bogs for rituals to nature gods and spirits. The distinctive ecological conditions of peat wetlands provide a habitat for distinctive fauna and flora. For example, whooping cranes nest in North American peatlands, whilst Siberian cranes nest in

9135-513: The sea route across the Manukau to Ihumatao (where Auckland International Airport is now). The main tribe to use this route and the main traders were the Maniapoto tribe. They occupied an area of fertile land south of Te Awamutu at Kihikihi and Rangiaowhia. Maniapoto sold wheat, peaches, potatoes and other food to Auckland and bought back shirts, sugar, tobacco and rum. The boom time ended in 1856–1857 with

9240-746: The sector employed 18,519 people, or 9.9% of the region's employed population. With a large dairy farming industry, the Waikato also has a large dairy processing industry. Fonterra operates dairy processing plants at Te Rapa , Te Awamutu, Hautapu , Waitoa , Tīrau and Lichfield . Other dairy processing plants include Tatua Dairy Company 's plant at Tatuanui , and Open Country Dairy's plant at Horotiu and Waharoa . The Waikato region has eight major freezing works : AFFCO at Horotiu, Greenlea at Hamilton and Morrinsville, Silver Fern Farms at Te Aroha and Waitoa, Te Kuiti Meat Processors and Universal Beef Packers at Te Kuiti, and Crusader Meats at Benneydale. The Kinleith Mill south of Tokoroa processes wood from

9345-476: The southern parts of Franklin District. That seems to be the only legislation naming it 'Environment Waikato', which had been its operating name until 2011, shortly after the 'Rates Control Team' won about half the seats in the 2010 election. In the 2010 local government elections, the Waikato Region had the country's lowest rate of returned votes. Since then the percentage turnout has declined further. The people of

9450-507: The state whilst 23% belong to the municipalities Bogs in Latvia are considered important habitats due to their ecological values, and up to 128,000 hectares, or 40% of the areas in the territory, are protected by environmental laws. The most famous national parks and reserves are the Ķemeri National Park , Cenas tīrelis and Teiči Nature Reserve . The climate, geography and environment of Finland favours bog and peat bog formation. Thus, peat

9555-614: The surrounding forests into pulp and paper. Before the arrival of Europeans, the Waikato contained the third most densely populated part of New Zealand, after Northland/Auckland and the Bay of Plenty. The Waikato rohe (area) was inhabited by iwi (tribes) such as those of the Tainui confederation, including Waikato and Ngāti Toa . Between about 1750 and 1842 the area was subject to a large number of invasions by other Māori iwi and hapu confederations and large scale population migrations took place by

9660-502: The topic. In 2010, IPS presented a " Strategy for Responsible Peatland Management ", which can be applied worldwide for decision-making. Peat extraction is forbidden in Chile since April 2024. Often, restoration is done by blocking drainage channels in the peatland, and allowing natural vegetation to recover. Rehabilitation projects undertaken in North America and Europe usually focus on

9765-410: The tropical to boreal and Arctic zones from sea level to high alpine conditions. A more recent estimate from an improved global peatland map, PEATMAP, based on a meta-analysis of geospatial information at global, regional and national levels puts global coverage slightly higher than earlier peatland inventories at 4.23 million square kilometres (1.63 million square miles) approximately 2.84% of

The region also includes the smaller towns of Huntly , Matamata , Morrinsville , Ngāruawāhia , Ōtorohanga , Paeroa , Putāruru , Raglan , Te Aroha , Te Kauwhata , Te Kūiti , Thames , Tīrau , Tuakau , Tūrangi , Whangamatā and Whitianga . The subnational gross domestic product (GDP) of the Waikato region was estimated at NZ$ 25.84 billion in the year to March 2019, 8.5% of New Zealand's national GDP. The subnational GDP per capita

9975-805: The water table and shading out many bog plants. Several families of plants including the carnivorous Sarracenia (trumpet pitcher), Dionaea (Venus flytrap), Utricularia (bladderworts) and non-carnivorous plants such as the sandhills lily , toothache grass and many species of orchid are now threatened and in some cases endangered from the combined forces of human drainage, negligence and absence of fire. The recent burning of peat bogs in Indonesia, with their large and deep growths containing more than 50 billion tonnes (55 billion short tons; 49 billion long tons) of carbon, has contributed to increases in world carbon dioxide levels. Peat deposits in Southeast Asia could be destroyed by 2040. It

10080-753: The water yellow or brown due to the leaching of tannins . Peat is widely used in balneotherapy (the use of bathing to treat disease). Many traditional spa treatments include peat as part of peloids . Such health treatments have an enduring tradition in European countries, including Poland, the Czech Republic, Germany and Austria. Some of these old spas date back to the 18th century and are still active today. The most common types of peat application in balneotherapy are peat muds , poultices and suspension baths . Authors Rydin and Jeglum in Biology of Habitats described

10185-436: The world by volume, in monetary terms, Latvian comes second in the world behind Canada . As an example, Latvia's income from exports was US$ 237 million. Latvia's peat deposits have been estimated to equal 1.7 billion tons. Latvia, as Finland due its climate has several peat bogs, which account for 9.9% of the country's territory. More than two thirds of the licensed areas for peat extraction are state-owned; 55% belong to

10290-469: The world land area. In Europe, peatlands extend to about 515,000 km (199,000 sq mi). About 60% of the world's wetlands are made of peat. Peat deposits are found in many places around the world, including northern Europe and North America. The North American peat deposits are principally found in Canada and the Northern United States. Some of the world's largest peatlands include

10395-466: The worldwide 500,000 km of degraded peatland may exceed 2.0 Gtons (including emissions from peat fires), which is almost 6% of all global carbon emissions. Peat can be a major fire hazard and is not extinguished by light rain. Peat fires may burn for great lengths of time, or smoulder underground and reignite after winter if an oxygen source is present. Peat has a high carbon content and can burn under low moisture conditions. Once ignited by

In the year to March 2018, primary industries contributed $ 3.14 billion (13.0%) to the regional GDP, goods-producing industries contributed $ 5.70 billion (23.5%), service industries contributed $ 13.35 billion (55.0%), and taxes and duties contributed $ 2.08 billion (8.6%). Between 2000 and 2004, Waikato economic growth was lower than the national average. But from 2004 to 2007, real gross regional product for

10815-434: Was passed enabling the formation of regions with united councils . Twenty regions were designated, excluding the Auckland and Wellington areas. For most of the country this was the first regional level of government since the abolition of provinces in 1876. Councillors were not elected directly – they were appointed from the various territorial local authorities (TLAs) within the region. The only responsibilities mandated by

10920-556: Was spoken by 95.9%, Māori language by 6.3%, Samoan by 0.6% and other languages by 12.4%. No language could be spoken by 2.2% (e.g. too young to talk). New Zealand Sign Language was known by 0.5%. The percentage of people born overseas was 21.7, compared with 28.8% nationally.
