Sanctuary Mountain Maungatautari, is a protected natural area in Waikato Region, New Zealand where the biodiversity of 3,400 ha of forest is being restored. The sanctuary covers the mountain peak, Maungatautari.
Most of New Zealand's ecosystems have been severely modified by the introduction of land mammals that were not present during the evolution of its ecosystems, and have had a devastating impact on both native flora and fauna. The sanctuary, surrounded by a pest-exclusion fence, is a good example of an ecological island, which allows the original natural ecosystems to recover by minimising the impact of introduced flora and fauna.
Maungatautari, as an eroded volcano was chosen as a suitable site for a major ecological project for a number of reasons, including the diversity of its terrain, the relative integrity of natural areas in spite of some human engineered changes, the commitment of surrounding communities, and the feasibility of fence-construction given surrounding developed terrain.[ citation needed ]
Some elements of the diversity of Maungatautari took scientists by surprise. In April 2006, the discovery of 100 silver beech trees caused considerable excitement in the botanical community. The tree, native to southern New Zealand, had not previously been believed to be present on Maungatautari, although researchers who came to investigate emphasized that the tree had probably been established during the last ice age. The largest of the trees were estimated to be several centuries old. Jim Mylchreest, Maungatautari Trust's chief executive, pointed out that the trees were not only exciting in themselves, but also for the fungi and insects they might host that also may not have been expected to be present on Maungatautari.[ citation needed ]
In December 2004, eleven endangered Hochstetter's frogs were found living on Maungatautari in a rocky region. There had already been discussions about potentially reintroducing the Hochstetter's frog to the preserve, and the rare discovery of the small population in an environment being prepared to protect them excites the scientific community.[ citation needed ]
A dead Duvaucel's gecko was found in a mouse trap in March 2010; this was the first sighting of this species on mainland New Zealand for almost 100 years, probably indicating a surviving population of the gecko within Maungatautari. [1]
Because poisons and trapping, traditional methods of pest control, have limited success and seldom last long, the creators of the plan decided to enclose the 34 square kilometres of bush with a 47 km pest-exclusion fence to create an ecological island. When the environment was rendered suitable, the area was to be repopulated with the entire suite of charismatic species that may now be locally extinct, such as North Island brown kiwi, North Island kōkako, kākāriki, tuatara and many others. Kākā already visited regularly and were likely to become resident if suitable methods are employed.[ citation needed ]
In November 2003, the Trust constructed two exclosures, at the north and south of Maungatautari, totalling 1.1 square kilometres. The Trust used these areas to demonstrate the fence's feasibility and to test pest removal methods, which were launched in September 2004. The exclosures are now predator-free and were used as holding areas for native species while the main fence was being built.[ citation needed ]
In November 2005 a 3 hectare area adjacent to the Southern Enclosure, the Tautari Wetland, was gifted to the Trust by the Tauroa family for takahē and other wetland birds. A Tuatarium for the future was designed and planted inside the area.[ citation needed ]
In July 2004, the Trust began constructing the Xcluder fence. In September 2006 the Trust completed fencing the entire 34 square kilometres to exclude all pests (and was able to take advantage of parts of the exclosures' fencing constructed at Stage 1). Then the Trust began eliminating pests by dropping poison, starting with brodifacoum in November 2006. A second application was made in December 2006. The combined effect of the poison, trapping and hunting eliminated brown rats, black rats, stoats, cats, weasels, ferrets, red deer, fallow deer, pigs, goats, possums, hedgehogs, rabbits and hares. In 2007 the sole remaining pest species was mice, and poison was dropped a third time, in September that year, to eradicate them. This failed, and in 2011 the trust introduced a new policy, focusing on controlling rather than eradicating mice. [2]
One of the greater challenges facing the designers of the Xcluder fence adopted for the purpose was addressing entry at streams. Since water levels fluctuate and a fence needed to address both debris and fish migration, the Xcluder was outfitted with an electronic surveillance system to alert the Trust if a watergate fails to properly close. There have been other challenges with the fence, including storm damage in July 2007 that was quickly repaired.[ citation needed ]
In July 2006, a viewing tower was constructed near a northern rata grove in the southern exclosure.[ citation needed ]
Since the beginning of the project, native species have returned to the area either naturally or through reintroduction. In July 2007, a 300% increase was discovered in the native beetle population of the southern enclosure. [3]
In December 2005 Maungatautari witnessed its first kiwi call in approximately a hundred years. Radio signals in April 2007 suggested that the kiwi may be sitting on an egg, but that nest was found to be bare. In September 2007, two kiwi eggs were discovered. Although one proved infertile, the other hatched in December 2007, the first kiwi egg known to have hatched on Maungatautari in a century.
As of 2021, 320 founders of the North Island brown kiwi (Apteryx mantelli) western taxon have been introduced.
In June 2006, the Trust began reintroducing species, starting with a pair of critically endangered takahē. In April 2007, three species of endangered whitebait (kokopu or native trout) were reintroduced. In May, kākā were put into a special enclosure to allow them to acclimatise before they were released; they quickly attracted wild companions. In November of that year, seven kākā were released from the aviary.
On 3 December 2007, the trust announced that they planned to reintroduce North Island robins, North Island kōkako, tuatara, popokatea (whiteheads) and hihi (stitchbirds) in 2008. March 2009 saw the release of 60 whiteheads (popokatea).
Between 2009 and 2011, 155 hihi (stitchbirds) were released over 3 translocations (135 from Tiritiri Matangi Island and 20 from Little Barrier Island).
2011 saw the release of 40 North Island robins from Pureora Forest with a further 40 in 2012.
In 2012 and 2013 200 Mahoenui giant weta ( Deinacrida mahoenui ) were introduced into the sanctuary. Also in 2012, 50 tuatara from Stephens Island were reintroduced.
In 2013, 40 North Island saddleback were translocated from Tiritiri Matangi Island.
In 2015, 40 North Island kōkako were translocated from Pureora Forest.
In 2021, 80 riflemen (titiponamu) were translocated from Pirongia and Pureora.
On July 20, 2023, four kākāpō were reintroduced to the sanctuary, becoming the first kākāpō living in mainland New Zealand in almost 40 years. [4] Despite extensive improvements to the perimeter fence, in October 2023, one of the kākāpō escaped by using a downed tree to climb out. The bird was located using the signal from its GPS transmitter and returned to the sanctuary. [5] A second group of six birds was introduced to the sanctuary in September. However, two further kākāpō found a way over the fence, and in November the Department of Conservation temporarily removed three birds from the sanctuary to a southern predator-free island, leaving the kākāpō population in the sanctuary at seven. The department commented that "“Kākāpō are flightless but are excellent climbers who can use their wings to parachute from treetops". [6]

Hoplodactylus is a genus of geckos in the family Diplodactylidae. The genus is endemic to New Zealand, one of the seven genera of geckos found only in New Zealand. Hoplodactylus comprises two species of large to gigantic brownish lizards.
The animals of New Zealand, part of its biota, have an unusual history because, before the arrival of humans, less than 900 years ago, the country was mostly free of mammals, except those that could swim there or fly there (bats). However, as recently as the Miocene, it was home to the terrestrial Saint Bathans mammal, implying that mammals had been present since the island had broken away from other landmasses. The absence of mammals meant that all of the ecological niches occupied by mammals elsewhere were occupied instead by either insects or birds, leading to an unusually large number of flightless birds, including the kiwi, the weka, the moa, the takahē, and the kākāpō.
Kapiti Island, sometimes written as Kāpiti Island, is an island nature reserve located 5.6 km (3 mi) off the west coast of the lower North Island of New Zealand and within the Kāpiti Coast District. Parts of the island were previously farmed, but it is now a predator-free sanctuary for endemic birds, including many endangered birds. The island is 10 km (6.2 mi) long, running southwest/northeast, and roughly 2 km (1.2 mi) wide, being more or less rectangular in shape, and has an area of 19.65 km2 (7.59 sq mi).
Tiritiri Matangi Island is located in the Hauraki Gulf of New Zealand, 3.4 km (2.1 mi) east of the Whangaparāoa Peninsula in the North Island and 30 km (19 mi) north east of Auckland. The 2.2 km2 (1 sq mi) island is an open nature reserve managed by the Supporters of Tiritiri Matangi Incorporated, under the supervision of the Department of Conservation and is noted for its bird life, including takahē, North Island kōkako and kiwi. It attracts between 30,000 and 32,000 visitors a year, the latter figure being the maximum allowed by the Auckland Conservation Management Strategy.
Kōkako are two species of forest bird in the genus Callaeas which are endemic to New Zealand, the endangered North Island kōkako and the presumed extinct South Island kōkako. They are both slate-grey with wattles and have black masks. They belong to a family containing five species of New Zealand wattlebirds, the other three being two species of tieke (saddleback) and the extinct huia. Previously widespread, kōkako populations throughout New Zealand have been decimated by the predations of mammalian invasive species such as possums, stoats, cats and rats, and their range has contracted significantly. In the past this bird was called the New Zealand crow. It is not closely related to the crow, but looks like one from a distance.
The New Zealand kākā is a large species of parrot of the family Nestoridae found in New Zealand's native forests. The species is often known by the abbreviated name kākā, although it shares this name with the recently extinct Norfolk kākā and Chatham kākā. Two subspecies of New Zealand kākā are recognised. It is endangered and has disappeared from much of its former range, though the re-introduction of North Island kākā at Zealandia in Wellington has led to an increasing population of the birds across the city.
Zealandia, formerly known as the Karori Wildlife Sanctuary, is a protected natural area in Wellington, New Zealand, the first urban completely fenced ecosanctuary, where the biodiversity of 225 ha of forest is being restored. The sanctuary was previously part of the water catchment area for Wellington, between Wrights Hill and the Brooklyn wind turbine on Polhill.
The stitchbird or hihi is a honeyeater-like bird endemic to the North Island and adjacent offshore islands of New Zealand. Its evolutionary relationships have long puzzled ornithologists, but it is now classed as the only member of its own family, the Notiomystidae. It is rare, being extirpated everywhere except Little Barrier Island, but has been reintroduced to two other island sanctuaries and four locations on the North Island mainland. Current population estimations for mature individuals in the wild are 2,500–3,400.
The saddlebacks or tīeke (Māori) are two species of New Zealand birds of the family Callaeidae. Both are glossy black with a chestnut saddle. Their taxonomic family is also known as that of the "wattlebirds" and includes the two species of kōkako, and the extinct huia. All members of the family Callaeidae have coloured fleshy wattles on either side of the beak; the saddlebacks' are a vivid red.
An ecological island is a term used in New Zealand, and increasingly in Australia, to refer to an area of land isolated by natural or artificial means from the surrounding land, where a natural micro-habitat exists amidst a larger differing ecosystem. In New Zealand the term is used to refer to one of several types of nationally protected areas.
Orokonui Ecosanctuary, called Te Korowai o Mihiwaka in Māori, is an ecological island wildlife reserve developed by the Otago Natural History Trust in the Orokonui Valley between Waitati and Pūrākaunui, New Zealand, 20 kilometres (12 mi) to the north of central Dunedin.
Pūkaha National Wildlife Centre is a captive breeding facility and visitor centre located in a protected forest area on State Highway 2 in New Zealand's Tararua district. It was formerly called Mount Bruce National Wildlife Centre, then Pūkaha / Mount Bruce National Wildlife Centre.
The birds of New Zealand evolved into an avifauna that included many endemic species found in no other country. As an island archipelago, New Zealand accumulated bird diversity, and when Captain James Cook arrived in the 1770s he noted that the bird song was deafening.
The Manaia River is a river of the Coromandel Peninsula in New Zealand's North Island. It flows north from its sources in the Coromandel Range, reaching the Hauraki Gulf at Manaia Harbour, 10 kilometres (6 mi) southwest of Coromandel.
Pureora Forest Park is a 760-square-kilometre (290 sq mi) protected area in the North Island of New Zealand. Within its rich rainforest are an abundance of 1,000-year-old podocarp trees. It is "recognised as one of the finest rain forests in the world". Established in 1978, after a series of protests and tree sittings, the park is one of the largest intact tracts of native forest in the North Island and has high conservation value due to the variety of plant life and animal habitats. New Zealand's largest totara tree is located nearby on private land.
Lake Rotokare is a landslide dammed lake in the New Zealand region of Taranaki. It is located 12 km (7.5 mi) east of Eltham.
Rangitoto Range is in the Pureora Forest Park in the North Island of New Zealand. Its main peaks are Ranginui, Mt Baldy and Rangitoto. It has the headwaters of the Waipā, Puniu and Mōkau Rivers and forms the eastern boundary of the King Country. Streams on the eastern slopes drain into the Waikato River.
The North Island kōkako is an endangered forest bird which is endemic to the North Island of New Zealand. It is grey in colour, with a small black mask. It has blue wattles. Because of its wattle, the bird is sometimes locally called the blue-wattled crow, although it is not a corvid.
Ark in the Park is an open sanctuary and conservation project in the Waitākere Ranges near Auckland. It is a partnership between Forest & Bird and Auckland Council that is supported by Te Kawerau ā Maki that aims to remove non-native pest mammals and predators and re-introduce species that were made extinct in the area.
