Tracking wetland changes through eDNA

A study has shown that environmental DNA, known as eDNA, may be valuable in measuring biological changes in wetlands. The eDNA is extracted from soils, air, water, and other substrates.

Researchers from Manaaki Whenua – Landcare Research sequenced microbial DNA from soil cores taken down to 4 metres below the surface in seven New Zealand wetlands in one of the few studies globally to have studied wetland microbes at such depths.

“The results showed distinct changes in microbial communities as we went deeper,” says study co-author Dr Olivia Burge.

Biodiversity monitoring in wetlands tends to focus on large organisms such as birds and plants, which can be relatively slow to respond to environmental change.

Lead author Jamie Wood says the strength of eDNA is that it allows researchers to study microbial groups (bacteria and archaea), which may respond faster to environmental change.

As a wetland is drained for agriculture, increased oxidation of the peat leads to more carbon dioxide emission. This is
a process driven by microbes, and the researchers saw an increase in the types of microbes responsible in the upper
layers of the more modified wetlands.

“An unexpected finding was that the effects of drainage also appeared at greater depths, below the water table, where the relative proportion of microbes responsible for carbon fixation and methane generation decreased,” he says. As part of the study, the researchers compared three similar wetlands with different degrees of human modification. When a wetland is drained for agriculture, increased oxidation of the peat leads to more carbon dioxide emission.

“Ultimately eDNA may provide a useful tool for monitoring real-time wetland condition and identifying when critical thresholds are being approached,” says study co-author Beverley Clarkson.

Restored wetlands bring diversity

DU's inaugural scholarship recipient Shannon Bentley is in the final stages of analysing data for her thesis on wetland restoration.

She says she is exploring how restoring wetlands from pasture changes plants, microbes and soil.

"Restored wetlands are home to more diverse native plant communities and soil microbial communities than pastures, preliminary results show.

"This diversity produces a wide variety of benefits for people. For example, restored wetland soils have an increased capacity to store carbon, attenuate floods, and remove excess nutrients. "However, restoration creates a wide variety of responses, with every restored wetland being different."

More to come from this space, she says.

Takitakitoa impresses trustees

"The best bang for your buck" is how New Zealand Game Bird Habitat
Trust Chair Andy Tannock described Takitakitoa Wetland in Otago on September 19.

Trustees visited the wetland near the Taieri River during the annual meeting of the trust which was held in Dunedin.

It was the first meeting of the new board appointed by the Minister of Conservation in July. It consists of Andy Tannock, DU Board member Neil Candy, former DU president John Cheyne, Jan Riddell, Mark Sutton and Chantal Whitby.

The trust met to review 14 applications made to the trust for wetland projects across the country for 2020 – they subsequently approved 11 of the applications.
The award-winning Takitakitoa project has previously received funding from the trust.

Takitakitoa has been one of the largest wetland enhancement projects undertaken without extra funding help from non-Fish & Game sources. Otago Fish & Game was gifted the lower portion of the wetland in 1994, around 40 hectares, and later obtained the upper portion of the 70ha wetland, through a land swap deal.

The project was launched with a $50,000 grant from the Game Bird Habitat Trust which was largely spent on constructing a 350-metre bund so the valley floor,

which was drained in the 1960s, could be reflooded. This took about two years to complete. Otago Fish & Game Council also put funds into the project.

"It was basically taking 32 hectares of drained, failed farmland and turning it back into wetland," says Otago Fish & Game chief executive Ian Hadland. "Takitakitoa is a shining example of hunter funding being used for greater conservation benefit.

This is an ecological restoration project which has benefits for not just duck hunters, but anyone interested in enhancing or conserving natural habitat for the future."

As soon as water refilled the wetland, all sorts of wildlife turned up, species that had not been previously observed there while it was in its degraded state, he says. "There’s clearly conservation benefits there that even I didn’t expect. Some creatures turned up that I didn’t even know were in the neighbourhood … like the pied stilts. There are probably 30 to 50 that have moved in to live and raise their chicks."

Wildlife included species well outside of Fish & Game’s area of interest such as inanga (whitebait), fernbirds, grey teal and royal spoonbills.

However, Ian points out that mallard ducks and some other game birds have also colonised the area, and allowed for the wetland to be used for novice hunting in particular.

"Getting the next generation of hunters out there to appreciate wetlands and learn their value is important. Those young hunters will undoubtedly fund similar conservation efforts in the future." Takitakitoa is a project that Fish & Game can hold up as "a great example of a duck hunter-funded conservation project", he says.

For more about the wetland and how to apply for Game Bird Habitat Trust funding, go to:

In December the Game Bird Habitat Trust was granted $360,000 over three years through the Government's One Billion Trees project.

The money will be used to establish plantings on projects that the trust
supports around New Zealand.

Trust chair Andy Tannock says this is a significant boost for wetland habitat projects and complements the trust’s goals.

Andy says the trust will be working on setting up a process to support the planting of natives such as flaxes and woody species at sites that have received the trust's funding support. Many of the projects are on private land.

Andy acknowledges the work of Dr Matt Kavermann, the senior fish and game
officer for Wellington Fish and Game Council who worked with the Ministry for Primary Industries to establish the grant.

A pond for pateke

Te Henga wetland, which covers 160 hectares and is the biggest in Auckland, has the potential to be the ideal wildlife habitat with acres of reeds, raupō, sedges, open water ponds and the Waitākere River coursing through it.

Forest & Bird’s project Habitat te Henga was born from a desire to protect the
wetland. It started in 2014 with intensive stoat control, using 100 DOC 200 traps, several A24s and some cat traps.

Two trap lines totalling 30 kilometres were regularly checked and reset by a dedicated trapper. Scores of DOC 200s and A24s have been added since.

Effective predator control was required before translocation of pāteke could be considered and the first contingent of 20 pāteke was released in 2015, with a survival rate of 80 per cent, leading to another release of 80 birds in 2016. This has been covered previously in Flight magazine.

This success brought us closer to that ideal habitat and aroused interest and support from the local community and a range of other organisations.

Matuku Reserve Trust Board was established when the last block of bush and wetland came up for sale. The trust was able to buy it in November 2016.

The property, at the head of the Te Henga wetland in West Auckland, has raupō
and sedge beds, and open water ponds along the meanders of the former course of the river.

There are remnant pukatea and kahikatea at the foot of mixed kauri-podocarp-broadleaf forest from which small streams and seeps enter the flats.

With several other conservation projects including the Ark in the Park, Habitat
te Henga, and Forest & Bird’s Matuku Reserve alongside it, the 37-hectare property has been named Matuku Link. Here, a nursery has been established providing most of the plants that are converting the kikuyu-covered flood plain into a range of wetland habitats. An old barn has been transformed and provides not only a volunteer base but already does duty as a site for wetland education to the many school, service, business, and community groups that help with planting and bird releases. An aim is to have an on-site educator to work with schools.

Dozens of local residents have become involved as part of a buffer zone, collecting their traps or bait from the barn and local interest is really heightened when, as has happened in the past two years, pāteke have bred in their ponds or streams.

Also exciting for our neighbouring conservation group to the north was their discovery last year of a pāteke pair that had dispersed several kilometres into the forest-clad stream that disgorges into the te Henga wetland.

New ponds have been constructed at Matuku Link, with one of them sporting a family of seven pāteke ducklings. A more established pair on an existing pond are
so placid and accommodating that almost all visitors get to see them plus or minus their ducklings.

A further new pond was part of a survey for a PhD study on ponds and sampling from its inception over the year showed that it only took five to six months until
the Macroinvertebrate Community Index (MCI) matched that of established ponds. The MCI measures water quality.

Measuring outcomes for wildlife with predator control in place has involved
biennial audio recordings for matuku and pūweto. Pūweto are also surveyed annually. Goodnature A24 traps were deployed 18 months ago between an
existing DOC 200 array to see if a benefit to wildlife could be shown using pūweto as an indicator species.

The DOC 200 traps have been in place for six years and with the recording of fortnightly trap catch data and sightings or detections of matuku [bittern], pūweto [crake] or pāteke, we have a basis to see if change is detectable.

Rodent monitoring is undertaken three times a year by Auckland Zoo staff as part of its Conservation Fund outreach.

Native freshwater fish present include both long finned and short finned tuna, and one stream surveyed also had Cran’s bully, common bully, banded kōkopu and an unidentified galaxiid. These surveys have been done by Whitebait Connection which has also tested water quality parameters. Testing showed high health
of the river and streams.

A second forest-covered stream surveyed showed only eels and kōura but the
presence of a large overhanging culvert is the likely cause of the difference. With Whitebait Connection’s help, a fish ladder has been constructed and followed by
repeat surveying.

At other sites, galaxiids have wasted no time in colonising upstream once
impediments are removed and we also trapped a banded kōkopu upstream of
the culvert within a fortnight.

As well as continuing to use G-minnow traps, we will be taking water samples
to test for eDNA (environmental DNA). Multi-species testing of DNA in the
water will show what fish we have but it is also possible our streams have Hochstetter’s frog and Latia, the native limpet [the world’s only mollusc with bioluminescence].

The rest of the wetland is privately owned, but access to see wetland
habitats is now possible at Matuku Link. River flats make for easy walking but
accessibility for wheelchairs and buggies is being enhanced with good surfaces
and our first boardwalk has its official opening at our World Wetlands Day event in February 2021.

Building this boardwalk and other infrastructure was made possible by the post-Covid Jobs for Nature scheme. Our World Wetlands Day event is one of two open days we usually hold each year but now the barn is finally renovated, we
expect to open more frequently.

The annual kayak trip down the river offers visitors an intimate view of a large healthy wetland as well as being a great fundraising event. This year the event
will be on Saturday, April 27.

Our newest pond, made possible by Ducks Unlimited NZ, is slowly filling and once the plantings are established, we look forward to seeing pāteke and other wetland birds using it.

Mission impossible

'They said we couldn't do it'

Contractors wildlife expert Sandy Bull and Ecoworks' Steve Sawyer bring birdlife into Nick's Head Station and look after the 2-metres-high predator-proof fence, which protects 35 hectares of native bush and a wide array of wildlife.

About 60 tuatara were translocated from Stephens Island in Marlborough Sounds, and now, safe within the fence, their numbers have grown to more than 100.

There are also about 180 nesting gannets, about 55 to 60 grey-faced petrels, sooty and fluttering shearwaters and even an arctic skua has been seen within the fence.

"Initially, they said we couldn't do it," Sandy says.

To attract the seabirds, Steve smothered the rocks with white paint to look like guano and installed a sound system to replicate the calls of various seabirds. The gannets have been nesting there for several years now.

Sandy says there are plans to translocate saddlebacks and giant weta. He has also been involved in translocating pāteke to the wetland and about 200 have been released. He says they are now moving around the region and another survey of bird numbers is due but it is clear the pāteke are doing well.

Sandy told DU members that he was well aware of the wealth of knowledge within DU and members' involvement with wetlands around New Zealand.

He says Gisborne is desperately short of wetlands. The biggest is Lake Repongaere, covering about 110 acres. "There are farm ponds all over Gisborne attracting wildlife but we are very short of big wetlands. This one [at Nick's Head Station] is a joy to behold."

Some of the visiting and resident birds:

  • pukeko – numerous (some have been culled);
  • paradise shelducks;
  • shags – black, pied, little, little black and kawau;
  • white faced herons; bittern – though they are seldom seen;
  • pied stilts;
  • kōtuku;
  • royal spoonbills;
  • godwits – spotted recently;
  • a nesting colony of black billed gulls, the world's rarest gull;
  • black-fronted terns – spotted once; dab chicks;
  • NZ scaups – in low numbers;
  • graylards – interbred with mallards and grey teal;
  • grey teals;
  • shovelers;
  • Canada geese; penguins – a colony on the beach;
  • oystercatchers; pāteke;
  • gannets;
  • petrels;
  • Arctic skuas;
  • fluttering shearwaters;
  • sooty shearwaters

DU's trip to a 'magic place'

The wetland at Nick's Head Station at Muriwai, south of Gisborne, is a world-leading example of positive human interactions with the land, and of what vision and money can achieve.

General manager Kim Dodgshun has worked at Nick's Head Station since 1994, eight years before the current owners bought the property. "They inherited me and we've worked well as a team ever since," Kim says.

When Kim arrived, the land that is now the main wetland was being grazed with livestock roaming all over, and with cows wandering along the beach. "It was nothing like it is today."

Early on, Kim had the idea of creating a bird reserve on the property and ran it past wildlife ecologist and former Wildlife Service ranger Sandy Bull.

The plan, however, hit a snag when the owners at the time said they did not wish to proceed with something that would not produce financial returns.

Undeterred, in 1995 Kim managed to obtain a $15,000 Natural Heritage Fund grant from the local district council and, with Sandy's help, starting trapping. "We caught a big polecat down on the beach," Kim says.

They also put up "No shooting" signs – it had been a popular duck shooting site, fenced off 15 hectares and planted flax around the outside. The birds flocked in, bringing seeds from other wetlands in the area and the plants began to grow.

The story of the wetland took another turn in 2003 when the farm changed hands after the Overseas Investment Commission approved an application from a US billionaire to buy the land, in what turned out to be a 12-month-long process.

He had first visited the farm in 2002 and embraced Kim's plans to create a wildlife reserve.

The final step for the sale was to gain iwi approval. Kim says communication was the key and once the iwi knew what the owner planned to do with the property, the deal was  approved.

In response to Kim's plans, the owner said, "Let's make this bigger and better", and brought out renowned landscape architect Thomas Woltz from the US to design the wetland, with advice from Kim and Sandy.

A previous manager who had farmed there for 35 years had set in place the foundations to drain the saltwater from the low lying areas. He put up a netting fence on the beach which collected all the driftwood and storm debris, building a natural wall with sand.

Next, he added another fence on top of that and planted it out with marran grass and other plants.

Later, in the 1960s, a drain was put in to get rid of the remaining saltwater but a narrow, shallow channel remained, with 700 acres of catchment running into it. In summer it dried up. The surrounding paddocks were all very wet with no drainage.

Kim had already planted some native blocks but as Thomas Woltz learnt more about New Zealand and its trees, "the master plan was to revert the land back to how it was 700 or 800 years ago, with a profitable farming operation, back when there were no predators and the land was covered in native trees", Kim says.

Planting began in earnest in 2003 and now there's almost 700,000 natives on the property – coastal varieties with "the big fellas" – rimu, matai and totara – planted among them.

The wetland project began in 2005 – plans were drawn up, the land was surveyed and work began, initially with six diggers.

Kim had warned the contractors that trucks with wheels and 20-tonne diggers wouldn't work in the boggy terrain, but they brought them in anyway and all of them got stuck.

Which left the six smaller diggers. Firstly, a wall was put in to stop the saltwater coming in over the original wall at the beach. "We put in some more small ponds up the valley and worked our way west."

Deep channels – "about 2½-cars deep" – were dug out to ensure the wetland had water year-round.

The material excavated from the channels was made up of a layer of Plasticine-like blue tacky soil sandwiched between shells and "rubbishy" soil. The blue material was used to seal the walls or build the islands, while the "rubbishy" soil helped shape them.

Diggers scraped up the topsoil which was carted on to the shaped islands by trucks with tracks to prepare them for planting.

However, when they came to seal the western side of the wetland, they ran out of the blue soil so plastic liner had to be used in some sections.

"We pegged out all the walls and had three diggers in a row, one digging the holes, another with a big roll of the plastic, working at snail pace, unrolling it, with a third quickly filling it in before the walls collapsed," Kim says. Thankfully, it worked.

"Once it was all done, we had to pump all the water out. "We got council permission to pump it out into the sea over sheets of corrugated iron to protect the beach."

In the process, they found some old kahikatea, big, old stumps of trees, leading them to believe that, pre-settlement, it must have been an old kahikatea swamp.

"There are some stumps on the beach visible at low tide that have been dated at more than 8000 years old," Kim says.

As well as dealing with the challenges presented by the terrain, during planting, they encountered another problem.

Holes were dug with an augur, and some crystal rain put in with soil over the top before the tree was planted with a fertiliser capsule.

Later they went back to one of the islands to put in stakes to mark where the native plants were but found that most of them had been pulled out.

"All the rats were just pulling them out and eating the fertiliser caps. They were having a ball."

The answer was to use about 100 bait stations with Pestoff rat bait, from Farmlands, and "there were bucketloads of rats coming in," Kim says. It's slowed down now.

"That was just another little challenge. I can't believe how well the plants have grown."

Now the islands are all finished and planted with native trees – 10,000 trees to the hectare. On the hills, it's 2500 to the hectare.

The wetland has two 1ha islands and several smaller ones. All the islands are in place of valleys, which was Thomas Woltz's plan, imagining erosion coming down and islands forming.

At its peak, 25 people were working on the project. The labour was all local and all the trees were sourced from the Muriwai area. "Now the locals come to get our native trees," Kim says.

The farm is 3300 acres in total with nine kilometres of coastline. It runs Angus cattle, 285 breeding cows and 3300 sheep. This is likely to be reduced to 3200, with the aim of getting more out of fewer stock, by doing things better, "by selling them when they are ready to go and when the market is ready to take them".

"We are looking at the possibility of going down the regenerative farming path, though the steep contours of Nick's Head Station add to the challenge – more investigations in this area are required."

Facial eczema is a problem so the farm focuses on sourcing facial eczema-resistant stock. The farm uses dicalcic phosphate fertiliser, not straight superphosphate, and nitrogen, which was seldom used, has not been used for about eight years.

The station employs a staff of 16, who look after conservation, including a former DOC worker who does trapping and twice-weekly night shoots by bike, general hands, stockmen, groundsmen, a secretary, a citrus manager and assistant, who have 50 hectares of citrus to tend, plus contractors.

Kim pauses, distracted by something that needs fixing. "Everything we do on this place, we got to maintain it.

"We've got this magic place that we've all had something to do with and created what it is today. We can't let it go back. We can't let wild pine trees start growing.

"We've got convolvulus – we've got to keep taking it out – we've got kikuyu grass on the farm that we have been spraying, we have got to keep at it. "

"The old place never sleeps."


  • The bus trip to Nick's Head Station was organised by Kees and Kay Weytmans, who provided delicious, nutritious packed lunches. Kees' efforts to make sure everyone was comfortable during the talks on the jetty by providing lucerne bales to sit on were also much appreciated.

Nationally Recognised restoration efforts

According to WaiWetlands, you should prepare to be inspired by nationally recognised restoration efforts at Wairio by community group Ducks Unlimited.

Once a paradise for waterfowl and aquatic species, the wetlands were greatly affected by drainage schemes in the twentieth century. Today they are a living example of what is possible through wetland restoration efforts.

World Wetlands Day events

The importance of wetlands was celebrated on Sunday, 2 February 2020, with events around New Zealand for World Wetlands Day.
This year’s theme was Wetlands and Biodiversity, to draw attention to the global decline in biodiversity and the crucial role of wetlands as biodiversity hot spots. The day marks the 1971 signing of the International Convention on Wetlands in the Iranian city of Ramsar.

The 2020 Puweto Festival honoured the day at Lake Rotopiko, which DU visited during its 2018 conference in Hamilton. Wetland bird masks, a critter colour-in, mudfish scrabble, eels and ladders, live geckos, kahikatea tree climbing and a virtual reality lake dive were among the offerings for families who attended.
The event was named after the shy puweto/spotless crake that lives around the margins of the lake.

Rotopiko is being developed into a National Wetland Centre, with newly completed boardwalks, information panels and an interactive discovery trail. During the festival, Treelands (local arborists) climbed up kahikatea to install bat roost boxes – something they have been doing all over the region. Other activities around the country included a guided walk at Harbourview-Orangihina Park in Te Atatu on 1 February and Matuku Reserve Trust in West Auckland had an open day to show off its wetland restoration and give the public a chance to see pateke.

In Wellington, Zealandia visitors were able to talk to experts from organisations including the Hakuturi Roopu, Greater Wellington Regional Council and Lakes380 to learn more about freshwater and wetlands in New Zealand.

In Marlborough, visitors were invited to check out a community-led wetland restoration project and walk around the Grovetown Lagoon. A guided walk was held around the Travis wetland in Christchurch.

The QEII National Trust took the opportunity on World Wetlands Day to introduce a new QEII wetland covenant to protect the Galloway Wetlands in Ashburton.

The trust said: “Craig and Lyn Galloway bought their farm in 1986 on the south bank of the North Branch of the Ashburton River. When they purchased the property, all paddocks had been developed except for the wetland paddock which remained uncultivated.

“Craig and Lyn applied to the Ashburton Water Zone committee for a grant to expand their successful riparian planting programme to the margin of a stream and man-made pond.

“Spring-fed channel wetlands like theirs have virtually disappeared elsewhere on the Canterbury Plains. They decided to place a covenant over the whole 
6-hectare wetland complex to preserve the relict pre-human vegetation.

“The covenant is a rare example of the highly diverse wetland complex and landform created by hydrologically connected springs associated with braided rivers. The wetland ecotone contains a spring-fed mossy fen, bog rush channel wetland, stream, manmade ponds, pukio and kiokio fern swamp, and toetoe marsh.

“The Galloway Wetlands protect the only known manuka, sphagnum moss and the pink-flowered wetland ladies tresses orchid (Spiranthes novae-zelandiae) on the Ashburton Plains.” Matagouri and the rhizomatous shrubby violet known as a porcupine shrub have survived on the stony ridges in the covenant but both are rarely encountered elsewhere in the region, the QEII Trust said.

The landowners plan to supplement these species with new plants, grown from seed sourced from the local area. This covenant is one of very few
that meet all four national priorities for protecting rare and threatened biodiversity on private land.

But it was not all good news for wetlands. In a statement released to mark World Wetlands Day, Forest and Bird said West Coast landowners had wiped out more wetlands in the past 20 years than landowners in any other region. Aerial images from around the country supplied by Landcare Research showed that wetlands on private land were still disappearing at an alarming rate.

The West Coast was the largest wetland region in New Zealand, with nearly 84,000 hectares of freshwater wetlands, 14 per cent of them in private ownership, Forest and Bird said.

Handy guide defines what makes a wetland

The first step in protecting wetlands is being able to identify them. To help landowners identify wetlands on their property, Greater Wellington has developed a guide: Spotting a wetland on your land.

This guide is a set of durable flip cards designed to be used outside, containing photos of different wetland types and plant species likely to be found in and around wetlands. Greater Wellington is also helping landowners to protect and manage waterways through its Healthy Waterways programme. This support can include help with the cost of fencing, pest control and planting.

Welcome to my world

Every tree on Jim Campbell’s family farm has a story to tell – and many of them he has nurtured from seedlings.

Pockets of the 508-hectare farm resemble an arboretum, with precious specimen trees fenced and surrounded by other trees planted there to protect it from stock and the elements.

Years ago Jim attended a Landcare lecture about having a good influence on the land.

Today the giant eucalypts, the valuable Tasmanian blackwoods (Acacia melanoxylon) (a good straight trunk can be worth $4,000 a cubic metre, says Jim), Douglas firs and Oregon pines, totara, sturdy pin oaks, giant redwoods, some kahikatea that Forest & Bird gave him, towering Leyland cypresses planted to screen the farm from SH2, tupelos and liquidambars with their brilliant autumn colour and hundreds of others are all testament to how he carefully he took that lecture to heart.

He is watching the progress of a hybrid oak he got from Appletons Tree Nursery in Nelson, a Quercus robur ‘Fastigiata’, which has an elegant upright shape and appears to be thriving.

The kanuka and manuka, which are almost in full flower (“it’s nearly time to tell the beekeeper in bring more hives”), have gained more value – “from cutting it and bulldozing it, I am now planting it... for the bees”.

On his daily rounds of the farm that his son, Simon, now runs, Jim gets a lot of pleasure seeing the trees stake their claim on the land, both the trees that preceded him and the ones he has planted. The biggest rata on the property was there long before he took over the farm.

“I thought the stock were going to kill it because they used to camp under it so that’s why we fenced it off and planted around it; that tree is now worth about $5,000 to me”, but it’s not a cost that Jim begrudges.

It’s clear to see Jim, who is now in his mid-70s, loves his trees.

When he ran the farm, which has been in his family for more than 150 years, it was about 60:40 cattle to sheep, with 200 station cows. Now his son runs 40 station cows but he’s also rearing bulls, which is cheaper than buying them in.
They are mostly speckle park crosses and angus hereford crosses.

Jim enjoys still being part of the farm and helps out with the haymaking – mowing paddocks – and checking on stock and other tasks. “I need to get
out – this morning I’ve done a couple of hours of spraying,” he said.

In line with current regulations, and with more stringent rules around the fencing of waterways likely, Jim says his son is lucky because a lot of it, along with planting, has already been done. “We were ahead of our time. We did it mainly to control the river wood trees, which were taking fences out.”
Simon is now trialling different tree varieties to carry on the planting but it is still going to be a massive cost to ensure all the waterways are compliant. The planting has other benefits as well as keeping stock out. Jim has discovered that a one-kilometre section of one of the streams that has established trees along it is about 2 degrees Celsius cooler because of the shade.

The Te Mara stream goes into Waipoua River on the property but by the time the Waipoua has reached Masterton, it has accumulated a lot of water, from the Kiriwhakapapa, Mikimiki and Matahiwi streams as well.

About 20 acres (8ha) of the property between the woolshed near the homestead, where Simon now lives, to where Jim lives above the “Big Pond” is covered by a QEII covenant. Jim thinks now that the covenant should be extended to another area on the farm called Norm’s Marsh.

It was built in tribute to Norman Marsh, a great supporter of DU and generous benefactor when it came to paying for the cost of creating wetlands, several – on Jim’s and other properties – thanks to Norm’s largesse. Jim, who was made a Member of the New Zealand Order of Merit for his services to conservation in 2016, is a life member of the QEII National Trust.


The property has about 32 ponds in all. One was created after former DU president John Cheyne, on a visit to the farm, suggested a particular rushy patch would make a good wetland. “It took me three days to bulldoze it and I had to hire a digger for a half-day,” Jim says. Another he calls the “10-Minute 
Wetland” – “that’s how long it took to block the end of it with a bulldozer – a pair of shoveler nested there this year and had five ducklings”.

On the big pond, Jim’s two mute swans, which he suspects are both male,compete with scores of scaup for the daily treats delivered by Jim. He says there were 32 scaup ducklings on the pond last year. As well as feeding the swans and scaup and other ducks, Jim has more for the pheasants, Cape Barren geese and quail that frequent the lawns around the house.

The other birds that visit the farm also have plenty to feast on. There’s dragon’s gold kowhai and kaikamako for the tui and bellbirds, tree lucerne,
or tagaste, for the wood pigeons and Himalayan strawberry trees, which all the birds love. He notes that the lucerne makes excellent firewood, “as good as maire”, something that many people don’t realise.

A welcome distraction over Christmas and New Year, as Jim recovers from an injury, has been the arrival on the lawn of some baby quail looking “like little bumblebees”.

He has been trying to breed quail for several years – there were five last year – but this year he has spotted one pair with 11 chicks, one with three and another with two chicks. “I can just look out the window and see them feeding on the lawn. It’s just magic to have them around all the time.”
For Jim, one of his favourite times of day is at night – sitting out on the deck having a whisky, with the Cape Barren on the lawn and the pheasants coming up to use the automatic feeder, and quail running along the deck.
