The Murchison Mountains are a group of mountains in Fiordland National Park in New Zealand. It is the location where the South Island takahē, a type of bird presumed extinct, was rediscovered in 1948.[1] The highest mountain is Mount Lyall at 1,892 metres (6,207 ft).[2]
Flora and fauna
[edit]Native birds recorded in the area include takahē, mohua, whio, kea, New Zealand kākā, kākāriki, New Zealand falcon, weka, rock wren, tomtit, tūī, bellbird, fantail, rifleman, grey warbler, brown creeper, silver-eye, pipit and kiwi.[3]
The 1948 discovery of the takahē, the largest living member of the rail family, happened after unrecognized bird footprints were found, and Geoffrey Orbell, an Invercargill-based physician, led an expedition to find the unknown bird.[4] After this, an area of 500 square kilometres (190 sq mi) was set aside for the conservation of the takahē.[5] Following the reintroduction of takahē to Gouland Downs in Kahurangi National Park, this is one of only two places where wild takahē can be seen.[6] It is the longest running conservation programme in New Zealand.[7]
With the aim of protecting the native bird populations, the New Zealand Department of Conservation started a program in 2002 to control stoats in the area.[3] In 2007, a population increase of stoats in the mountains after a beech and tussock mast seeding led to a halving of the takahē population.[8] The numbers of red deer in the Murchison Mountains steadily grew between 1930 and 1973 but hunting on foot and helicopter reduced the population by 60% between 1973 and 1975.[9] In a 1953 expedition to the Murchison Mountains for the Canterbury Museum, W. R. Philipson discovered a new type of plant from the genus Pachycladon, Pachycladon crenata.[10] A study in 2007 found that the New Zealand rock wren population in the Murchison Mountains had dropped by 44% in the last 20 years compared with a study in 1989.[11]

In 2002, DoC started a low-intensity but large-scale operation to control stoats in the Murchison Mountains. These form a 51,000 ha peninsula on the western side of Lake Te Anau. Protected on three sides by the lake and on the fourth side by remoteness, the area is home to a number of increasingly scarce native birds. Most famous is the takahe, but also present are mohua, blue duck, kea, kākā, kākāriki, New Zealand falcon, weka, rock wren, tomtit, tūī, bellbird, fantail, rifleman, grey warbler, brown creeper, silver-eye, pipit—and kiwi.

Unique and endangered wildlife – Fiordland is home of the Takahē Recovery Programme. This unique bird, the largest living member of the rail family, was once thought to be extinct. After the rediscovery of the takahē in the Murchison Mountains in 1948, a special area of 500 square kilometres (190 sq mi) was set aside in Fiordland National Park for its conservation.

Life is tough in the takahē's alpine home, but by 2007, things were looking up. The population in the Murchison Mountains had almost reached 200 birds when disaster struck. Following a beech and tussock mast (a mass seeding of beech trees and tussocks which happens every few years), the mountains were besieged by a plague of stoats. Within the span of a few months, the wild population of takahē was halved.

Numbers of red deer (Cervus elaphus scoticus) increased steadily in this area of New Zealand from the 1930s to 1973 causing extensive damage to vegetation and competition with takahe (Notornis mantelli), a rare flightless bird. Hunting on foot and especially by helicopter reduced the red deer population by 60% between 1973 and 1975 and has nearly eliminated red deer from alpine grasslands which are the main habitat for takahe. Future management for sustained harvest of deer and acceptable competition with takahe is discussed

In 1953, when taking part in the Canterbury Museum Fiordland Expedition, I collected a small cruciferous plant from rock crevices at 5,000ft on the mountains west of Lake Te Au in the Murchison Range. The plants were very similar to Pachycladon novae-zelandiae in general appearance, but differed in possessing simple, not stellate hairs, and in the crenate, not pinnatifid, leaf margins.
