More about the forest restoration
 

Restoring this last remnant of Te Tapere Nui o Whatonga now lies in the hands of this generation of New Zealanders. The restoration to a living forest full of birds not seen here for over 50 years, began in 1996 when North Island kaka were re-introduced.

This small population was managed to ensure it has survived and bred in the forest. Now their future is much brighter with management of the predators. This project will cover the entire forest and it is planned to ensure the numbers of rats stoats and possums are reduced right down to give the kaka, and many other birds that could be returned into the forest, a real chance to increase.

With intensive pest control the Mount Bruce Forest will see a 50 percent increase in bird life every year for at least the first five years, and possibly many years beyond. It will also ensure the survival of our rare and endangered species providing habitat for up to 600 kaka, 400 kokako, 500 kiwi, and thousands of tui, fantail, waxeye and other native species.

The restoration project hopes to make the Pukaha Mount Bruce forest “alive” again, with renewed mauri for the future.

So far we have achieved;

  • The Pukaha partnership, neighbors, iwi, local community and Regional Councils are working together.
  • Pests that devastated Pukaha have been dramatically reduced.
  • Kaka have been released into the forest, and are now breeding prolifically. Over 40 birds are now flying free and visitors are able to experience one of the densest populations of North Island kaka.
  • The song bird of the forest, the kokako was once prolific in Pukaha Mount Bruce but last seen 40 years ago Birds have now been restored to the forest.
  • Kiwi, absent for over a 100 years have been returned.
  • This was the first time in the history of New Zealand, that Kiwi and Kokako had been reintroduced into the wild to a place on the mainland that they had become extinct from. These species are breeding and further reintroductions are planned.
  • Wild native bird populations such as tui, bellbird, kereru and whiteheads are also increasing in numbers.
  • The innovative “Sponsor a hectare” scheme that enables everyone to contribute to the protection of a hectare of forest within Pukaha Mount Bruce. This concept has now been adopted by other restoration projects.
  • Production of “Pukaha Songs of the Forest”, a CD developed with Rangitaane o Wairarapa and featuring the highest quality bird song recording and our own Pukaha waiata performed by Rangitaane o Wairarapa.
  • We are leading the way in showing that it is possible to restore our precious wildlife back into the wild on mainland New Zealand.

The Restoration Strategy

Introduced animal pests have caused the extinction of approximately half New Zealand’s bird fauna. Uncontrolled animal pests limit wildlife numbers and the species that can be introduced. They also threaten rare plants, forest structure and composition, lizards, bats and invertebrates.Most fauna species (especially birds, bats, reptiles and mega-invertebrates) are threatened with predation by introduced mammals. Successful establishment of populations requires intensive and ongoing protection from these predators. Levels of vulnerability to predators also differ. Transfer from wild populations and captive breeding are important reintroduction tools. The order of introductions is important. Some native species can limit the establishment of other native species through predation and competition.

In May 2001, the Department of Conservation, Rangitaane O Wairarapa and the National Wildlife Centre Trust joined forces to restore the Pukaha Mount Bruce Forest. The ‘Pukaha Restoration’ project was established with the goal being to restore the forest, with the first step being to get pest numbers down to very low levels. This agreement was formalised with a Memorandum of Understanding signed by the three parties.

It was acknowledged at the time that the restoration project would need to be fully funded by the community to be viable. Ongoing annual funding in the vicinity of $150,000 per annum is required to fund a project of this magnitude. Since this partnership agreement was signed, thousands of pests - rats, stoats, ferrets, weasels, mice, hedgehogs and feral cats - have been removed from the Scenic Reserve and surrounding farmland. In mid-2002, Greater Wellington Regional Council and Horizons Regional Council started laying traps and bait stations within the 2700 hectares of private land surrounding the Scenic Reserve. Greater Wellington has since widened the control area to further improve the habitat both inside and outside the DOC Reserve.

Progress

Over 100 kilometres of tracks have been cut within the reserve, along which DOC has laid rat-traps every 50 metres and bait stations every 100 metres. Close to 1000 traps have been laid by Greater Wellington and Horizons MW Regional Councils and are checked and re-baited weekly. Pest control within the Reserve has been funded primarily through sponsorship and the Department of Conservation. Regional Council pest control has been achieved through direct funding from Greater Wellington and from Regional Initiatives funding from Horizons Regional Council.The success of the pest control project has enabled the re-introduction of kokako and kiwi into the forest. Kokako and kiwi have been extinct from the area for at least sixty and one hundred years respectively.

A further milestone occurred when, just six months after the release of the parents, two kokako chicks fledged in early February 2004 Kaka have also benefited from the restoration project and the wild Pukaha Mount Bruce kaka population had increased to approximately 40 birds when numbers were last recorded in May 2004 wild native bird populations such as tui, bellbird, kereru and whiteheads have also increased in numbers and we expect to see a 50% growth in native bird populations over a number of years once the area is freed from the effects of pests.

 
Restoration Goals
  • All extant species that once resided in Pukaha Mount Brucehave been successfully restored or re-introduced and all populations are thriving.
  • Restore and maintain a healthy functioning forest ecosystem in perpetuity.
  • Pukaha Mount Bruce is internationally renowned for captive management, species re-introduction and forest restoration.
  • Pukaha Mount Bruce develops and demonstrates leading conservation techniques.
Objectives-pest control and flora/Fauna
  • Eradicate (where feasible) and control (where necessary) animal pests to maintain healthy forest structure, function and processes.
  • Maintain low pest numbers to enable healthy forest bird, lizard, bat and invertebrate communities.
  • Reintroduce species in priority order and establish viable populations by 2012.
  • Use captive breeding/propagation to establish viable populations of species that have been lost from Pukaha.
  • Reintroduce kaka, kokako, and kiwi by 2004, and establish viable populations.
  • Reintroduce robin, kakariki, hihi, saddleback, tieke and short-tailed bats and establish viable populations by 2012;
  • Breed kaka at the NWC and release juvenile kaka at Pukaha annually.
  • Establish self –sustaining hihi and short-tailed bat breeding programmes at the National Wildlife Centre.
Monitoring & Survey
  • Permanent plots will be established and monitored to interpret succession processes and stability of plant assemblages, by July 2005
  • Monitoring described above is carried out on time.
  • Conduct biodiversity surveys to determine what plant and animal species are present at Pukaha.
