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.

If you have any questions about wetland identification or are planning to do anything in or around waterways or wetlands, get in touch for free specialist advice at This email address is being protected from spambots.

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.

Bittern steals the show

Ducks Unlimited recently received a substantial donation to put towards its restoration work at Wairio Wetland.

Janet and Patrick Velvin, who live in South Wairarapa, are passionate about conservation, particularly water conservation, and contacted The Gift Trust, a philanthropic advisory service, to identify suitable causes they could support.

Cheryl Spain, executive director of The Gift Trust, said they had been impressed with the research on Wairio and DU’s partnerships with the Department of Conservation, Greater Wellington Regional Council and Victoria University, particularly its links with the student research projects at Wairio, and had chosen Wairio as a suitable recipient.

The Velvins visited the wetland for the first time and took part in a planting day with Victoria Uni students in early July.

After helping with the planting, they were given a guided side-by-side tour by Ross Cottle, who identified a suitable site on a promontory for a viewing hide, which could be constructed with some of the funds donated by the Velvins.

During the tour, Patrick asked if there were bitterns in the wetland, and as if on cue, a bittern obliged and flew in front of the them.

Janet became aware of the work at Wairio Wetland through the book Wairarapa Moana: The Lake and its People.

Janet said after the tour they were impressed with Ducks Unlimited and happy to give a donation towards the work at Wairio.

The evolution of Courtney’s Close

On a parcel of land at Mangaone in Raetihi, in an area that was once an unproductive, narrow, boggy drain bound by strong ridges, co-owners Graeme Berry and Paddy Chambers saw a potential habitat for waterfowl.

DU Patron Di Pritt says, “Since Graeme and Paddy Chambers have been involved at Mangaone, from 2004, they have created six major wetland areas – ranging from an acre to 10 acres – which are all fenced and they have planted about 38 acres. Another four major ponds have also been created.

“It is an amazing achievement, and was fully supported by the previous owner, Jon Preston.”

Their latest project is Courtney’s Close, a wetland area they named after the Horizons employee who helped with the project.

They created it by splitting a 300-acre paddock in half and building a 650-metre deer fence. The wetland area now consists of four ponds outside the fence, and three, with room for two more, enclosed by the fence.

This means animals have access to water but are excluded from the lower wetlands and impurities are filtered out along the way.

Inside the fences Graeme and his partner, Bang, have planted natives, protected from the deer.

Pekapeka wetland earns Pride of Place award

One of the areas to be visited during the AGM weekend.

Hawke’s Bay Regional Council was  delighted to receive a Distinction Award from the New Zealand Institute of  Landscape Architects at the NZILA Resene Pride of Place Landscape Architecture Awards for 2013 in April.

The citation for the award states that Pekapeka Wetland provides a range of  experience opportunities for users and  acknowledges the contributing work of Shannon Bray Landscape Architect.

Stephen Cave, HBRC’s Operation  Environmental Manager said “This is one of three awards for Pekapeka Wetland  since 2009, realising its champion value and raising the awareness of wetlands throughout Hawke’s Bay.

“The award from NZILA is a great  reflection on the restoration work  happening in Hawke’s Bay and we are  very honoured. It is estimated this award puts Pekapeka Wetland in the top five  percent of landscape architecture projects undertaken throughout New Zealand in  recent years.”

The award recognises Pekapeka Wetland as a high quality interpretive site for wetland restoration. It is noted for integrating public accessibility with educational  features, using local materials and stories.

Stephen is quick to acknowledge a number of the project’s key supporters, particularly Shannon Bray, Waa Harris, Peter Dunkerley, the Community Foundation, Rotary Club of Stortford Lodge, Eastern and Central Community Trust and the preliminary work of Titchener Monzingo Aitken Ltd.

Iwi groups plus many children from schools (particularly Pukehou School) and Kiwi Conservation Club all played a key role in planting areas around the swamp.

Help at hand for Waikato wetlands

Tony Roxburgh, chair and trustee of the  National Wetland Trust provided the AGM with a glimpse of happenings with wetlands in Waikato.

The Trust plans a state-of-the-art interpretation centre, with research and educational facilities, wetland gardens and heritage trails on land next to Lake Serpentine in the Waipa district. This is one of 69 peat lakes in Waikato.

Issues to be worked through include highway access and formal agreement with the  Department of Conservation. DoC has already given approval to construct a 1.4 km predator fence around 10ha of the reserve at Lake  Serpentine near Ohaupo.

Tony said the plan includes a visitor concept plan, an interpretation plan, business plan and landscape developed for the site. These were funded by grants from Transpower, Trust Waikato and Waikato Regional Council (Environmental Initiatives Fund), and  supported by Waipa District Council.

They are looking at the best way to restore wildlife, including the feasibility of a predator exclusion fence. Funding from the Waikato Catchment Ecological Enhancement Trust, and a grant from the DoC’s Community Conservation Fund allowed them to produce a re-vegetation plan to restore vegetation and habitat.

Students of Te Awamutu School have been searching for native and exotic fauna, and have been the first to confirm long-tailed bats at the site. Other species confirmed include Australasian bittern, North Island fernbird, Black mudfish and Spotless crake.

The pest fence was completed in June this year and they now need sponsors and  donations to help with pest eradication and  re-introduction of native species.

Other work in the Waipa district includes Lake Ngaroto one of the peat lakes. It currently floods the peat and Tony said this could be one of the larger projects for the Waikato basin aimed at reducing loss of wetland and preserving the quality of the peat lakes.

Canada needs wetlands (so does NZ)

Ducks Unlimited Canada are celebrating 75 years of existence this month, October 20013. In a special souvenir issue put out by the Calgary Herald there is a piece that explains why Canada needs wetlands. In New Zealand we need wetlands to be looked after as well, so here are the reasons given by the Canadians. These are reasons New Zealand can also take to heart.

Ducks Unlimited Canada are celebrating 75 years of existence this month, October 20013. In a special souvenir issue put out by the  Calgary Herald there is a piece that explains why Canada needs  wetlands. In New Zealand we need wetlands to be looked after as well, so here are the reasons given by the Canadians. These are reasons New Zealand can also take to heart.

Wetland - like marshes and ponds are some of the most productive ecosystems in the world. They work behind the scenes, providing many important benefits to all Canadians.

Clean water: wetlands filter harmful pollutants from the water we drink and improve the health of our lakes and rivers.

Homes for wildlife: hundreds of species depend on wetlands for food and raising their young.

Flood and drought prevention: wetlands act like giant sponges, holding water during wet periods and releasing it during dry periods. Fun and recreation: wetlands are beautiful places for people of all ages to be active and enjoy nature.

Given all they do, it is shocking that wetlands continue to be lost. Every day up to 80 acres of wetlands are lost in Canada. Your help is needed. Join Ducks Unlimited, Canada’s conservation community at www.ducks.ca

 

The following are excerpts from another article in that Calgary Herald publication linking science with nature and wetlands. This is already happening with the work DUNZ has 
instigated at Wairio Wetland in the Wairarapa. In Southland Waituna Lagoon is also 
attracting scientific interest.

Science is helping to increase the knowledge about wetlands and what they do. Ducks Unlimited Canada biologist Owen Steele said: “As one of the Earth’s most  productive ecosystems, wetlands are also among the most threatened.

“A lot of people don’t care if wetlands are a good place for ducks or frogs or anything else, society is so urbanised we’ve lost touch with nature. “But if their home is going to get washed away of they’re no longer able to drink their tap water because of disappearing wetlands, they are suddenly interested. “

Steele says if the river that runs through their town is going to be green, scummy and unattractive to walk by, they are going to sit up and pay attention.

Research in North America clearly shows the critical environmental benefits wetlands provide, which include clean water and habitat for wildlife, reducing flooding and erosion and lessening the impact of climate change.

As wetlands are lost so too are the benefits they provide. These include phosphorus removal - without wetlands more phosphorus will go into our lakes and rivers.

There is also the carbon stored in wetlands. The biological diversity and the social benefits of wetlands start adding up. Landscape changes that include roading, rail lines and pipelines can all affect wetlands.

Owen Steel said: “Things like our jobs, the economy and our health are all important  issues; we need to figure out a way to link  wetland protection and conservation to those issues.

“We still have a long way to go in prevention of wetland loss.”
