Taranaki is linked by legend to the mountains of the central North Island. It is said that Taranaki carved out the bed of the Whanganui River on a tragic flight from its ancestral home to the east. Today Taranaki is still venerated and its summit is sacred to the tangata whenua of the area.
The land was first formally protected in 1881 when its slopes (within a 9.6 kilometre radius of the summit) were made a forest reserve. Development of huts, tracks and roads followed. Gradually more land was added to the reserve and in 1900 it was made a national park, the second in New Zealand after its not too distant neighbour, Tongariro. It has been a popular tourist destination ever since.
Ambury Monument /Ambury Bluffs west of Humphries Castle were named after Arthur Hamilton Ambury. He gave his life in a heroic attempt to save W E Gourlay who slipped on the ice on 3 June 1918. Both men died in the fall over the bluff. Ambury Monument is on the Holly Hut Track closest to the Camphouse.

Egmont National Park is a mountainous area that encompasses three volcanic cones. The main peak of Mount Taranaki (2,518 m) forms the nucleus of the park. It is the most recent and only active volcanic peak in the park, although it is now considered dormant. Because it is considered one of the most symmetrical mountains in the world, it is a very distinctive landmark. The other two volcanic cones, which are now extinct, form the basis of the Pouakai and Kaitake Ranges in the north-western part of the park.
Lava flows, ash showers and lahars (debris flows) have transported volcanic material away from the peaks. The oldest lava flows on Mount Taranaki are preserved in the west, but erosion has removed a number of older flows, resulting in the picturesque forms of Humphries Castle, Lion Rock and Warwick Castle (Tahuna a Tutawa). Fanthams Peak was formed when magma found a weak point in the volcano and created a secondary vent on the side of the mountain.

Egmont National Park is important nationally because it contains a diverse range of vegetation that has developed in an environment of frequent volcanic activity. The vegetation ranges from semi-coastal and montane forest to tussocklands, alpine and scree communities. The vegetation changes in a remarkably short rise in altitude compared to other places.
The area's high rainfall and mild coastal climate has allowed a lush rainforest to develop. However its nature changes the higher you go on the mountain - from tall rimu and kamahi trees at lower altitudes through dense subalpine shrubs to an alpine herbfield with some plants unique to the park.
The forests of the park are composed of native conifer and broadleaved tree species, with beech trees notably absent. Other outstanding features are the large number of northern rata trees and one of the most extensive kahikatea-rimu-kamahi semi-swamp forests in the North Island.
The lowland coastal forest of the Kaitake Range is a very different forest than that found in the rest of the Egmont National Park. The trees here are not found in the higher areas.There are nikau, titoke, kohekohe,and puriri trees. You’ll find pukeatea and karaka trees and see silver fern and a range of smaller plants. A stand of Californian redwood trees, planted in the 1930s are protected by a special dispensation in the Egmont National Park Management Plan. Other exotic trees planted at the same time are slowly being removed to allow regeneration of native species.
The vegetation patterns in Egmont National Park are complex. The vegetation at any given place is the product of not only climate but also of the site’s parent rock material, slope, aspect, drainage and soils. Past and ongoing disturbances also influence the patterns (e.g. volcanic eruptions, landslides, cyclones, logging and browsing by introduced mammals). As a result, the vegetation types do not form predictable altitudinal zones. For example, the tall, lowland rimu-kamahi-rata forest is replaced by relatively low stature forest on the western slopes of Mount Taranaki, where debris flows devastated the forest less than 400 years ago.
A third of the park’s plant species are found in a small area of swampland called Ahukawakawa, which lies between the main cone and the Pouakai Range. The area forms the headwaters of the Stony River (Hangatahua), which is also protected for its cultural, historic and scenic values. Many of the plants found here have special adaptations to the acidic soils and very low temperatures.
Another unusual type of vegetation found in the park is the high-altitude kamahi forest known as ‘Goblin Forest’. When volcanic eruptions destroyed large areas of rimu forest about 400 years ago, kämahi became the dominant species here. Many of the kamahi trees are growing epiphytically on old totara and rata trees destroyed by the eruptions. They developed distinctive gnarled, intertwined trunks as they grew around the old, dead trees. The heavy rain, highly leached soils and cold temperatures of these forests make suitable conditions for kamahi, while other forest types cannot survive.
As the only large forest tract within the Egmont Ecological District, the park provides the district’s only habitat for many bird species. Twenty eight native bird species and 15 introduced bird species occur regularly in the park. Threatened species include North Island brown kiwi, fernbird and blue duck.
The park is home to several unique invertebrate species, and almost half of New Zealand’s indigenous fish species are found in or near the park. Nationally threatened fish species include the giant kokopu, short-jawed kokopu, banded kokopu and koaro.
Introduced mammals continue to have a large impact on the park’s native inhabitants, through predation and the destruction of healthy natural habitat. Possums in particular have affected canopy tree species, leading to the death of large areas of trees through defoliation. Possums also eat bird eggs and chicks and large invertebrates such as the giant Powelliphanta land snails.
In the past, goats have hugely modified the understorey of the forest through browsing, bark biting and trampling. Today, thanks to intensive goat control operations, goat impacts are negligible.
Although most of the park is free of introduced plants, several potential weed problems exist. Wild ginger was a major problem in the park prior to a concentrated removal effort in the early 1990s, and surveillance continues in case of any major re-establishment. Asparagus scandens has also become a major problem in regenerating forests of the Kaitake Range fringe. Old man’s beard and hawkweed are also potential invaders.

What is DOC doing?
Egmont National Park is an island of indigenous vegetation surrounded on all sides by pasture. This provides an opportunity to protect and enhance threatened species here, through intensive protection and pest control operations.
The Department of Conservation aims to monitor threatened species, to provide ongoing protection against threats such as introduced plants and animals, and to reintroduce species that have disappeared from the park once the habitat is deemed safe for them.
Blue duck (whio) have already been reintroduced to the park and ongoing translocations are occurring to ensure the successful establishment of the population. Kiwi and blue duck restoration programmes are being supported by various sponsors including Taranaki Kiwi Trust, Central North Island Blue Duck Recovery Trust and the Bank of New Zealand.
