The track will be fully open for use from 12.00 am Saturday December 14.

The affected section of track, between the Pike29 Track junction and the Pororari Hut was closed due to a significant slip last week and it was initially thought repairs would see it closed until the 21December.

Chris Hickford, Operations Manager for the Greymouth District says the reopening is a week ahead of schedule.

“We’ve had some good luck, good weather, and better than expected geology which has meant the job of blasting a new bench across the slip went really well.

“We know how important the track is for the regional economy. The team has pulled out all the stops and put in some very long days to get this section of track reopened during this busy period.”

The slip that took out the track was approximately 25-30 metres wide and extends for quite some distance on a steep slope above and below the previous track alignment.

A new track has been benched across the slip face, and while further finishing work will be required in the New Year it is now able to be reopened to a standard suitable for safe public use.

Rūnanga member Rachel Wesley says the weeklong dissection led by Te Rūnanga o Ōtākou in partnership with Te Papa Atawhai Department of Conservation, with support from Tūhura Otago Museum and Ōtākou Whakaihu Waka University of Otago, was groundbreaking for not only science but also in terms of creating new frameworks for how indigenous groups can work with western science.

“Not only was this tohorā (whale) the first of its kind to be dissected by science, but it was also the first time our hapū (subtribe) worked with scientists to pull together indigenous and western knowledge systems so we can all gain a better understanding of the whale and its behaviours,” Rachel says.

“This process was led by our rakatahi (young people) and guided by our esteemed guests from Ngāti Wai – Hori Parata and his son Te Kaurinui – who are tōhuka (experts) in working with these taoka (treasures). By working with and learning from leaders in te ao Māori, as well as leaders in western science, our rakatahi can revive ancient matauraka (knowledge) and develop an in-depth knowledge system to pass onto the next generations.”

The 5-metre-long male spade-toothed whale washed ashore at Otago’s Taiari Mouth in July. It was the first time a complete specimen has been recovered in good condition for examination.

The examination, led by DOC Marine Science Advisor and beaked whale expert Anton van Helden involved mana whenua from Te Rūnanga o Ōtakou, scientists from New Zealand, plus three leading US marine biologists: Dr Joy S. Reidenberg, Dr Michael Denk, and Dr Alexander Werth, completed on Friday.

Mr van Helden says a lot of new discoveries were made last week, with more to come. But one point of interest was Dr Denk’s discovery of tiny vestigial teeth in the upper jaw.

“These little teeth embedded in the gum tells us something about their evolutionary history. It’s remarkable to see this and it’s just another thing that we had no idea about,” Mr van Helden says.

Scientists also found that the whale had nine stomach chambers, which was previously unknown.

“In some of those stomachs we found squid beaks and some lenses from the eyes of squid, a few parasitic worms, and maybe some other parts of organisms that we are not quite sure of. We have a parasitologist who will study them to find out what they are,” Mr van Helden says.

“We also found interesting structures associated with both feeding and sound production. Weights and measurements and descriptions were made of various muscles and organs, to help us describe this species and make comparisons with related species.

“These all add to the body of knowledge we are building.”

Te Rūnanga o Ōtākou named the whale Ōnumia, which reflects the traditional name of the area where the whale beached. Ōnumia is located on the mouth of the Taiari River, on the Taiari Native Reserve. By naming this whale, Te Rūnanga o Ōtākou are reestablishing a traditional practice that maintains their strong bond with the environment, while also affirming their traditional names.

Dr Reidenberg says this is the first time she has worked with an indigenous group through the entire dissection of a whale and the experience was hugely rewarding.

“It was incredibly different to have the involvement of Te Rūnanga o Ōtākou, because in a normal dissection, we just want to know what attaches between A and B,” Dr Reidenberg says.

“But all the other things we have learned about the importance of the whale to the Māori people, about the traditional stories, the sacredness of the whale, in particular certain parts of the whale, we may have been totally oblivious to and now we can be more sensitive because we understand more, and we’ve enjoyed learning more.”

Mr van Helden says bruising to the head and neck and a broken jaw has led scientists to believe the whale suffered some sort of head trauma that may have been the cause of its death.

“We don’t know but we suspect there must have been some sort of trauma, but what caused that could be anyone’s guess,” he says.

From here, scientists will analyse the data they have recorded from the whale and publish their findings under the direction of Te Rūnanga o Ōtākou.

“It’s a week I’ll never forget in my life, it’s certainly a highlight and it’s the start of the storytelling around this beautiful animal,” says Mr van Helden.

Department of Conservation Director General Penny Nelson presented the award to Mr Barkla, who was nominated by the New Zealand Plant Conservation Network, with supporting letters from several botanical societies, conservation boards, tertiary institutions and researchers.

John worked for DOC for over 30 years in a range of roles in Whanganui and Otago and continues to serve on the New Zealand Plant Conservation Network as he has done for many years (three of them as President) and has been a member of the Botanical Society of Otago for over two decades.

He continues to support DOC with threatened plant conservation in the Otago region and is a highly respected field botanist who has been a panel member of the New Zealand Threat Classification System team assessing the threat status of vascular plants. He has also supported regional threat classification assessments.

“John’s passion for plants is legendary,” says Penny Nelson. “He volunteers extensively in his own time, going in to battle for plants that others might overlook, such as small leaved tree daisies (Olearia) and Inland Cresses (Lepidium).

“Recently he discovered a new population of Craspedia “Cape Saunders’ on Otago Peninsula. He has also rediscovered rare plants such as Veronica lilliputiana, and Myosotis rakiura on the Otago Peninsula and the only known extant population of a small daisy – now known as Solenogyne christensenii – near Lake Wanaka.”

“Thanks to John’s successful seedling trials we also know a lot more about how to propagate the Nationally Vulnerable Olearia hectorii,” says Penny Nelson.

“John is an outstanding botanist who generously shares his extensive botanical knowledge with others. I’m told he has collected more than 700 specimens for herbaria – housed in seven different institutions.

“His contribution to citizen science is enormous – making more than 25,000 observations of his own and helping confirm identification for another 76,000 observations.

“After being professionally and personally involved in plant conservation for more than four decades, John Barkla has made an enormous difference for our native plants and is thoroughly deserving of this award.”

One of Aotearoa New Zealand’s oldest conservation awards, the Loder Cup was donated by avid plant collector and enthusiast Gerald Loder in 1926 to encourage and honour New Zealanders who work to investigate, promote, retain and cherish New Zealand’s indigenous flora.

With fewer than 35 individuals remaining, every nest, egg, and chick is vital to the survival of this iconic species.

Encouraging start to the season

The tara iti breeding season is off to a bumper start, with 9 active nests recorded and 25 eggs laid. 8 chicks have successfully hatched through the DOC/Auckland Zoo captive rearing partnership, and 3 chicks have hatched in the wild. Fingers crossed the season continues as it has started.

DOC Ranger Nikki Hartley says “We’re thrilled to see so much activity early on in the season. It’s a super busy time, but every successfully fledged chick gets us one step closer to safeguarding tara iti for future generations.”

Protecting the tara iti: A collaborative effort

The success of last year’s record-breaking season, where 22 eggs were laid and 14 chicks hatched, was achieved through a combination of predator control, innovative chick-rearing techniques, and habitat protection. This year, DOC continues to build on these advancements:

• Predator control efforts have already ramped up, with hundreds of traps deployed to protect nesting sites. Cats, mustelids, and rats remain the primary threats to tara iti eggs and chicks.
• Incubating eggs and hand-rearing chicks at Auckland Zoo remains critical tools in increasing productivity and growing the population.
• DOC is also doing research to help better understand the tara iti population dynamics and the threats they face, to ensure we are well equipped to reduce risks to the species.

Key nesting sites and community involvement

Once widespread, the tara iti now breeds at only 4 main nesting sites north of Auckland: Papakānui Spit, Pākiri Beach, Waipū and Mangawhai sandspits.

DOC collaborates closely with partners including Patuharakeke, Te Uri o Hau, Ngāti Wai, Ngāti Whātua o Kaipara, Ngāti Manuhiri Settlement Trust, Auckland Zoo, The Shorebirds Trust, the NZ Fairy Tern Charitable Trust, About Tern, Birds NZ, Tara Iti Golf Club, and the Waipū About Tern Trappers.

Generous support for the tara iti season has been provided by the Shorebirds Trust, Endangered Species Foundation, Pākiri Beach Holiday Park, Tara Iti Golf Club, Auckland Council, Manāki Whitebait, Tongariro National Trout Centre, and New Zealand King Salmon.

To help tara iti and other endangered shorebirds

• Stay out of fenced areas and use designated walkways. 
• Avoid shorebird nests and chicks.
• Keep dogs on leads and out of reserves. 
• Remove bait, fish, and rubbish to deter predators.
• Avoid driving or cycling on the beach.
• If you are being chased, swooped at, squawked at, or if a bird is on the ground pretending to be injured, you are too close to a nest.
• If you find a nest do not touch it and move away quickly. The parent birds will be close by.

“Everyone has a role to play in protecting tara iti. By being mindful of your actions and supporting our efforts, you’re helping to secure the future of this precious species.”

“We love that everyone wants to be hanging out at beaches and estuaries enjoying our beautiful coastline this summer. By remembering that we are sharing these spaces with taonga species like tara iti, and being mindful of your actions, you’re helping to secure the future of this precious manu,” says Nikki.

People can boost efforts to save tara iti by donating through the New Zealand Nature Fund: Tara iti/ New Zealand Fairy Tern | New Zealand Nature Fund.

DOC has partnered with NZ Nature Fund to raise funds and accelerate critical conservation work to protect threatened species like tara iti.

Looking ahead

With continued innovation in conservation techniques and strong community support, DOC remains hopeful for another successful season.

Visitor activity and feedback between 1 July 2023 to 30 June 2024 shows more local and international visitors are using DOC’s bookable accommodation compared to last year.

DOC’s Heritage & Visitors Director Catherine Wilson says around one and a quarter million bednights were booked for DOC accommodation in the 2023/2024 season.

“This contributed roughly $18.25 million towards the costs of providing these facilities. As DOC also provides many non-bookable huts and campsites, the total number of bednights for DOC accommodation will be far greater.”

A bednight is defined as one person occupying one bunk or campsite for one night.

Bookings for non-Great Walks sites increased 28% on the previous season, to 1,007,069 bednights, while Great Walks were up 10% to 249,277.

The growth in use is down to several factors including facilities being reopened after weather-related closures, and more huts and campsites becoming bookable.

New Zealanders, understandably, continue to choose easily accessible options for getting outdoors, says Catherine Wilson.

“Most of the top 10 places visited by New Zealanders are in the North Island, near coastal areas and population centres.

“Protected natural areas near Auckland such as Long Bay-Okura Marine Reserve and Rangitoto Island were most popular, while iconic heritage sites near Auckland are also well visited.

“Short walks of less than three hours duration remain the most popular activity for both New Zealanders and international visitors.”

“International tourism continues to recover from the impact of the pandemic,” says Catherine Wilson, “In June 2024 international visitor arrivals were up to 87% of pre-pandemic levels.”

“An estimated 72% of these undertook a walk or tramp while here, highlighting the importance of nature to our visitors.”

Fiordland and Aoraki Mount Cook national parks in the South Island had the highest levels of international visitor activity. In the North Island, Tongariro National Park attracted the most international visitors.

Compared with the previous year, international visitor bed night bookings on the Great Walks increased by around 27%, bookings by New Zealanders increased by 2%.

Catherine Wilson says as both domestic and international visitor numbers increase, so too does pressure at popular places, making it all the more important for people to visit responsibly.

“It’s disappointing to see around a third of New Zealanders noticed visitor impacts at the natural areas they visited, with damage to natural landscapes observed the most.”

“This summer, we all need to do our bit to protect the natural and cultural heritage we enjoy outdoors.”

DOC’s visitor insights reports are produced biannually covering the peak summer period and full year (July to June). They are designed to inform DOC’s work and support evidence-based visitor management decisions at regional and national levels. These reports also provide New Zealanders with an understanding of visitor activity in conservation areas across Aotearoa.

One of the oldest huts in Te Papa-Kura o Taranaki, Pouākai Hut sits just below the junction of the Mangorei and Pouākai Tracks on the Pouākai Range. Offering northward views across the Taranaki coastline, the 16-bunk hut has sheltered generations of day walkers and overnight trampers since it was built in 1981.

The original hut has been dismantled, and the start of construction marks a new phase of development for the Taranaki Crossing.

The project is funded by Kānoa – Regional Economic Development & Investment Unit’s Provincial Growth Fund ($13.4 million), with additional funding to support the project provided by the Department of Conservation ($3.4 million).

The Taranaki Crossing Project is a partnership between Ngā Iwi o Taranaki, DOC, and Kānoa – Regional Economic Development & Investment Unit. All three partners are excited for the construction of a new Pouākai Hut.

DOC Hauraki-Waikato-Taranaki Regional Director Tinaka Mearns says Pouākai Hut has traditionally been the busiest in the national park, with a 95% occupancy rate in the busy summer period.

“After years of service Pouākai Hut is now showing signs of considerable wear and tear – and with demand for overnight stays increasing, it’s appropriate to provide visitors with a facility that is fit-for purpose,” says Tinaka.

Liana Poutu, Co-Chair of the project and Ngā Iwi o Taranaki representative, says the replacement work is a significant component of the Taranaki Crossing Project.

“The increased capacity of the hut will assist in managing the safety and environmental impact of increased visitor numbers to the area,” says Liana.

“The new hut will provide a facility not only for increasing visitor numbers, but also opportunity for visitors to engage in the cultural narrative for the hut’s design”

Taranaki Iwi Representative Jacqui King says mana whenua have been involved since the start in helping shape the design to honour ngā maunga and manaaki for manuhiri throughout.

“Collaborating closely with DOC, the process has come up with a building that ensures the hut’s footprint is no larger than the existing site to lessen the impact on the taiao,” says Jacqui. “This was balanced with the need to ensure manuhiri have the necessary manaaki and extended facilities to cope with the growing visitor numbers.

“Ngā Mahanga a Tairi’s cultural narrative is being developed in readiness for the final stages of the build to help deepen manuhiri connection and respect for ngā maunga. As tangata whenua, we are looking forward to sharing these stories with the wider community.”

The Mangorei Track to Pouākai Tarns will remain open throughout construction, with the track re-routed around the active work site. Visitors are asked to follow the advice of signage or workers on site to keep everyone safe.

Pouākai Hut has been temporarily removed from the DOC booking system while works are underway, and camping will not be permitted. Tinaka says while temporary toilets have been established, there will be no water on site, so visitors should come prepared for the changed conditions.

“We expect to open the new Pouākai Hut to be open to visitors in May 2025, with bookings reopening closer to the time,” says Tinaka. “Like all our work on the maunga, this project relies on good weather, so we can’t set a firm date for completion. However, we will provide updates on this mahi as it progresses.”

Construction of the new Pouākai Hut is being undertaken by Taranaki-based firms, further supporting the Taranaki Crossing Project’s economic goals.

Background information

The Taranaki Crossing was initiated via a feasibility study on the economic development strategy for Taranaki in 2017.

When the work is completed, the visitor experience on the mountain will reflect the relationship between DOC, mana whenua and the maunga itself.

The Taranaki Crossing project will also strengthen connections to the maunga’s natural and cultural heritage, enhance biodiversity and provide opportunities for local people, including iwi, to express their kaitiakitanga of the mountain by sharing their stories.

Date:  10 December 2024 Source:  Te Papa Atawhai Department of Conservation and Mahi Mō Te Taiao Waikanae Jobs for Nature

The Waikanae Mahi mō te Taiao project was established four years ago as part of the Government’s Jobs for Nature programme, building on an existing environmental partnership between mana whenua, Ātiawa ki Whakarongotai, Kāpiti Coast District Council, Greater Wellington Regional Council, and the Department of Conservation.

The project aimed to train and develop kaimahi in skills like environmental restoration, pest control, sustainable land management, and riparian planting.

The injection of Jobs for Nature funding boosted the partnership’s work to restore the health of the Waikanae River and achieve social outcomes. An independent review of Jobs for Nature has found that around $4 of benefits have been delivered for every dollar invested across the DOC-funded projects.

The project has been managed by local firm Groundtruth. Kristie Parata, Iwi Coordinator for Groundtruth, says a key aim of the project has been enabling rangatahi to train and work as kaitiaki on their awa and whenua.

“Through this work, we have achieved so much for our people and for our taiao,” says Kristie. “Our kaimahi have learned a wide range of skills, including plant nursery, environmental monitoring, fencing, track cutting, and pest control. Many have also reconnected with their past and heritage, and discovered new life paths and future goals, which is incredibly rewarding.

“We have learned to appreciate that a healthy taiao requires a lot of boots on the ground. The hard mahi of weed control and planting, contributing as kaitiaki, has brought our whole whanau on a journey of wellbeing.

“As a community, we all have aroha for this place we call home.”

The outputs from the project include over 22,000 riparian plants and over 100,000 other native plants planted, 2000 hectares of goat control, and around 600 hectares of possum control. 67 trainees across 10 groups graduated through a 3-month course, receiving unit standard training and hands-on learning. Many of these tauira have gone on to become kaimahi on project work, and to find employment in the conservation sector and beyond.

Kāpiti Coast District mayor Janet Holborow, Chair of the governance group, said the great success of the partnership has laid the foundations for future collaborations.

“It shows how we can all do better together,” says Janet. “The skills and connections gained by kaimahi have wider ripples far beyond themselves and this project. They’re able to go on to make significant contributions to their whānau, iwi, and the wider community. That’s something we can all benefit from.”

Ātiawa ki Whakarongotai is now looking to transition this project into an iwi-led environmental business to support continued delivery of employment and environmental outcomes at Waikanae.

The legacy also continues on the more than 2000 hectares of the catchment supported by property or work plans guiding their restoration over years to come.

Tēnā koutou katoa

Today I am joined by my senior leadership team:

• Henry Weston, Deputy Director-General Regional Operations
• Stephanie Rowe, Deputy Director-GeneralBiodiversity, Heritage and Visitors
• Ruth Isaac, Deputy Director-General Policy and Regulatory Services
• Mike Tully, Deputy Director-General Organisation support
• Tame Malcom, Deputy Director-General Treaty Relationships
• Sia Aston, Deputy Director-General Public Affairs

I want to set the scene of what DOC’s achieved, what the challenges are and where we’re heading – will take the full 10 minutes.

This year we refreshed our strategy, and our new purpose is Toitū te Taiao – we protect and restore nature.

We are focused on being the best we can be and mobilising others to take action for nature.

I’m really proud of what DOC staff have achieved this year, in challenging circumstances.

Biodiversity

Our National Predator Control Programme achieved its best ever results.

We adapted quickly to an unexpected beech mast and delivered 28 aerial 1080 operations across 735,000 hectares. Monitoring shows rats were consistently reduced to undetectable or very low levels, stoats and possums were effectively controlled. Mice were also routinely reduced to low levels, giving relief to native insects and lizards.

Our interventions have seen bumper breeding seasons for tara iti, kākāriki, northern Royal Albatross, kakī, and sea lion pups in Dunedin.

We completed the largest and most ambitious marine fieldwork season ever undertaken in subantarctic region.

We ramped up our wild animal management to give forests more chance to regenerate. We delivered over 1.2 million hectares of wild goat control in 23/24 and 140,000 hectares of wild deer control.

Visitors and recreation

We built and repaired a lot of visitor assets, including huts, tracks and bridges, after repeated storm damage and Cyclone Gabrielle.

We’ve recently opened a new great walk at Tuatapere Hump Ridge, and reopened Cathedral Cove. We said we would open it in early December and despite interruptions with bad weather and people ignoring track closures – we did it.

Auckland’s Te Henga walkway’s been reopened, Godley Head has been cleaned up, and we have a new visitor centre for Punakaiki.

We are ready for summer visitors.

Treaty partnership

We’ve achieved more for conservation by working with our Treaty partners. For example:

• With Ngāti Porou and Te Whanaū a Apanui, we’ve delivered pest control in Raukūmara, to help protect over 117,000 hectares from pests.
• On Matiu Somes Island in Wellington, we worked with the kaitiaki board to replace a wharf on time and on budget. And to ensure sustainable visitation to the island.
• And alongside Te Roroa we’re protecting kauri by replacing infrastructure.

Internally, we’ve set up a specialist asset management unit and made big improvements to our IT systems and network.

We have done all this while achieving savings of $47.2 m in the past year, and keeping our staff engaged.

The Minister of Conservation has given us four clear priorities

• Targeting investment in high value conservation areas
• Improving the regulatory system
• Exploring new revenue options so we’re financially sustainable
• And maintaining and building positive working relationships with Māori.

In terms of high value conservation areas – the first thing we did is work to better understand the value of nature.

Research shows the ecosystem services that public conservation land provides, such as fresh air, quality soil, clean water and pollinators are worth around $11 billion per year.

The natural and physical capital on conservation land is currently worth $133 billion, with National Parks worth $12.6 billion to New Zealanders.

On top of that, tourism on public conservation land is worth around $3.4 billion a year and supports regional economies through jobs and visitors spending money in communities.

These numbers are significant and yet they only cover the third of NZ’s land area that we currently protect.

This suggests to me that nature is New Zealand’s biggest asset. It’s vital for the economy. It’s also our insurance policy against climate change.

Healthy forests will prevent downstream impacts on urban areas during severe storms.

Nature is also important of course, for its own sake, and because spending time is good for us physically and mentally.

New Zealand thrives if we preserve, protect and restore nature.

We have a new approach to the way we do our biodiversity planning.

As you know, native species are in trouble – we’ve worked out it would cost $2.3 billion to manage all threatened species to persistence, which is way beyond our means.

So we are getting smarter and deliberately targeting our investment towards efforts that make the biggest difference. That means:

• Investing more money into species at the top of the cliff, the ones we could lose if we don’t take action
• Focusing on protecting our offshore islands from pest incursions – because they’re safe havens for vulnerable species
• Shifting more into managing threats across representative ecosystems and landscapes – we need more space for species to thrive – and they don’t pay attention to boundaries
• Developing new tools, techniques and carrying out research to support our decisions.

We have developed a new biodiversity planning tool that guides us on where we need to invest and will help us measure how successful our management is.

• This will be a game changer once it’s fully implemented in the next year.
• It maps our current spend, gives us clear priorities against the key work programmes (species, threats, ecosystems, obligations and research)
• It will help us develop clear target and objectives that will flow through to multi-year plans
• This tool will give us more information on the tough choices and trade-offs that need to be made to protect native plants, birds, insects and taonga species.

In terms of improving our regulatory system – we have put out a discussion document about making the conservation management system simpler.

We have agreed clear key performance targets with the Minister, and already, we’ve had an 80% increase in the number of permissions applications we’re processing each week.

While we’ve been modernising the way we work, we’ve also been inputting into the Fast-Track legislation and standing up how we will implement it.

For the priority about generating revenue – we have put out a discussion document about charging access to some areas and are doing a car-parking trial.

We’ve launched a nature prospectus to encourage business and philanthropists to invest in projects that extend or accelerate the core work we are already doing.

We are future proofing our visitor network, so it meets the changing needs of visitors and is more affordable, and we’re working on a mobilising for nature programme to get all New Zealanders to invest in nature.

The final priority is about maintaining and building positive working relationships with Māori.

DOC has over 3380 Crown monitored settlement commitments – 89% of them are either on track or have been completed.

We are holding 20 hui before Christmas to discuss the consultation documents to modernise the conservation system.

To sum up

It’s been a challenging year, but we have delivered against our priorities.

We expect to have more challenges next year – like all Government departments we’re being asked to absorb inflation and salaries, which means our baseline is dropping.

We will continue to prioritise our work carefully.

And we are focused on becoming a more innovative organisation, that achieves great things for nature, energises our people, and mobilises others to care and invest in nature too.

I look forward to discussing this work with you further.

It’s a stark reminder of the impact introduced predators like feral cats have on New Zealand’s vulnerable native wildlife, especially during breeding season.

Predator control, island enhancement for nesting, and bird monitoring has been undertaken in the area for about a decade. The project is funded by Canterbury Regional Council (Environment Canterbury), DOC and Toitū Te Whenua Land Information New Zealand (LINZ), and much of the work is carried out by Wildlife Management International Limited.

DOC South Marlborough Senior Biodiversity Ranger Pat Crowe says a single male feral cat reached a large island with 95 nests, eating several adult birds, chicks, and eggs, and disturbing the colony to the point where almost all nests have been abandoned.

“The devastating incident has destroyed the largest colony on the river despite extensive predator control in the area. It highlights how difficult it is to trap feral cats, which are intelligent and wary.

“The timing is particularly bad as most nests had chicks, or eggs that were about to hatch, which means they won’t have the time or energy to nest again this season.

Pat Crowe says it’s a real kick in the guts after all the work that’s been put into protecting these threatened birds, and the steady gains made over the past decade.

Canterbury Regional Council (Environment Canterbury) Principal Biodiversity Advisor Frances Schmechel says it’s essential the work continues as Canterbury provides vital habitat. About two-thirds of their nesting habitat occurs in the braided rivers of this region.

Toitū Te Whenua Land Information New Zealand (LINZ) Biosecurity Manager Tracey Burton says the incident highlights the importance of predator control in helping native species have a fighting chance.

“It’s sad to hear that one feral cat has decimated nearly an entire colony of these special birds that we’re all working so hard to protect. It’s a horrible reminder of the impact predators can have and why controlling their numbers is vital.”

Burton says LINZ is working closely with DOC and Environment Canterbury to control predators along the Waiau Toa/Clarence River and other braided rivers.

LINZ has been supporting predator control work on the Waiau Toa/Clarence River over the last five years.

Background information

Black-fronted terns are endemic and have a conservation status of “Threatened – Nationally Endangered”. They have a national population of 5-10,000 birds, which is declining.

Feral cats are opportunistic and skilled hunters, and among the top introduced predators across many New Zealand’s ecosystems. With their high prey drive, they have a major impact on native birds, bats and lizards. They can weigh up to 7 kg and measure up to a metre long (including the tail).

Braided rivers like the Waiau Toa are dynamic and globally rare ecosystems which face pressures from weed encroachment, introduced predators and land use changes, in addition to human disturbance.

Department of Conservation Senior Biodiversity Ranger Ben Gordon says each year kiwi are caught in leg-hold traps set for possums, causing injury and often death for the unfortunate birds.

“A kiwi can easily be caught by the leg or beak in a leg-hold trap, often causing injuries the bird can’t recover from.

“We’re asking the trapping community to help kiwi by setting these traps at a kiwi-safe height of more than 700 mm off the ground.”

Kiwi are ground-based birds not given to climbing. A simple 1 m long wooden board secured from a tree at an angle of 45 degrees to the ground allows access for target species while effectively deterring kiwi.

Brown kiwi are doing well, and the population in Coromandel has grown significantly thanks to long-term predator control programmes run by DOC and the wider community.

“The great success of Coromandel kiwi means they’re moving into more areas, and are at greater risk of encountering traps,” says Ben.

As with all trapping regimes, target animals should be treated humanely and not left to suffer – leg-hold traps must be checked daily and animals dispatched quickly.

For more information on how to set kiwi-safe traps contact your local DOC office.

Background information

Key Points to effective leg-hold trapping in a kiwi zone are:

• Trap is minimum of 700 mm off the ground.
• Board is approx. 1 m long and at a 45-degree angle to the ground.
• Trap is attached to the board and the chain is attached as low as possible.
• Board is on the uphill side of the tree.

Legal and humane use of leg-hold traps is described under the Animal Welfare Act 1999 and the Animal Welfare (Leg-hold Traps) Order 2007: Traps and devices: animal welfare and pest management
