The Nikau Foundation has appointed a new General Manager who brings a wealth of experience from the community and voluntary sector. Louise Parkin has had 25 years working with charitable and philanthropic organisations both in New Zealand and internationally.
Ms Parkin had been at Nikau Foundation as their Philanthropy Advisor for six months before taking up the role of General Manager in January this year.
In her spare time, she teaches the Japanese martial art of aikido to adults and children. Her personal philanthropy is for the benefit of the environment and international aid.
The Nikau Foundation is part of a world-wide network of community foundations set up to benefit a specific geographic area, in this case the Wellington region. The Foundation manages 22 endowment funds that benefit the arts, education, social and youth projects, the environment and beyond. It does this through the generosity of local donors. The funds it manages grew 100 percent in the last year.
The presentation of DUNZ’s certificate “in recognition and appreciation of support to NZ’s waterfowl and wetland habitat” to Ian Gunn from Greater Wellington Regional Council (GWRC) – Manager of GWRC’s Wairarapa Moana Project and a great supporter of the Wairio Wetland Restoration Project.
Ian was critical in securing a “step change” in funding for the project. The presentation was made at the end of the meeting along with the small gift of a bottle of wine. DUNZ members may recall Ian joining us at our 2014 AGM in Martinborough.
The recent meeting was held at Fish & Game’s Kilmore Lodge, adjacent to the Wetland where the group planning the 2016 work programme was underway.
Funding currently tots up to around $30,000. Of this, about $20,000 is already funded by contributions from our supporters.
June 21 work started at 9am for the organisers, supported by some strong lads from Taratahi Agricultural Training College and farm workers from a local sheep and beef station Palliser Ridge. Those strong farming trainees dug holes in pre-sprayed spots in rough, fescue infested terrain.
Just after 10am we also had about 20 school children from Martinborough and Kahutara primary schools arrive to “assist” in planting flaxes in the holes prepared by the aforementioned lads and workers. In all, around 65 folk helped with the planting and by 12 noon, 750 plants (about half of them kahikatea) were in the ground at the noreastern corner of the Wetland.
Greater Wellington Regional Council provided educational support and the school children, in addition to planting, were treated to a field class identifying plants common to the Wetland. That and the hot sausages for lunch (again provided by GWRC) made a great day for the children who said they would be back next year to see how “their” plants were growing.
The weather was not wonderful, but Robin and Heather List are seasoned birders and the pair set off to Wario to check on birds and do a count.
Robin said “The expedition consisted of Heather and me. We have the gear and do wetlands in squalls right cheerfully, so there was no grumbling in the ranks, though the waterproof notebook was abandoned in favour of the little recorder, which worked well under wet, windy conditions. The sun broke through at times and the whole place was looking grand as wetlands in winter can.
“There wasn’t a feather of a Dabchick nor yet a Bittern to be seen, so we’ll go looking in other haunts. It is possible they haven’t read the books and aren’t breeding yet, but it has been a mild winter.
“What we did see or hear in the space of 2 hours 10 minutes, not counting the walk along the road back to the car was, here in random order.”
Black swan 135,
Mallard X Grey 26, (possibly a couple of Shovellers among the tussocks at the sheds pond, but I think they prefer Boggy Pond)
All up16 species were seen by this intrepid pair, who also had an enjoyable lunch and excellent company in beautiful surroundings.
“Who could ask for more?” said Robin.
The Wairio Wetlands were on the list for the 200 members of the New Zealand Farm Forestry Association being hosted by the Wairarapa branch for their 55th annual conference.
Our own DU member and director, John Dermer is currently their national president. Wairarapa Farm Forestry president Stu Orme, and secretary Shane Atkinson, were thoughtful enough to write to Jim Law and thank him for hosting their field trip to Wairio:
“We would like to thank you for the effort you put in to host our field trip to the Wairio wetlands. Your restoration project directly addresses all three themes of our conference and is an outstanding example of a local initiative on a grand scale. Lake Wairarapa dominates the whole of the lower valley and the re-creation of wetlands along the degraded eastern boundary is a task with very long-term benefits. All our visitors enjoyed their trip. Thank you again.”
John Dermer said that all 200 of the NZFF conference attendees visited Wairio.
“We visited Castle Point Station in the north and down to the southern end to Prinoa Station and Waiorongomai on our last day with a look at Wairio and a talk from Jim Law.”
John said that once again he was struck by the sheer size of the Wairio Wetland although it was living up to its name, 'dry water' at the time. “Jim told us about the weed issues, mainly tall fescue, which makes getting trees established more difficult and the answers we are trying to find. One thing I noticed was how well plants are managing on the piles of soil excavated, so my main question is Why not do more? “There must be a shallow water table underneath so why aren’t we digging deeper? “What is the point of digging holes so shallow they don’t hold water?” John said there is no way he would site his maimai on this bit of dry wetland. He said he is sure the Farm Foresters were impressed, and they certainly asked lots of questions.
A cheque for $6500 from the Nikau Foundation was handed over to Ducks Unlimited (DUNZ) President Ross Cottle and Patron Jim Campbell by Gus van de Roer of the Nikau Foundation to go towards the restoration of the Wairio Wetland.
Nikau Foundation Chairman Kevin O’Connor said he was delighted the Foundation was able to support Ducks Unlimited with its restoration work at the Wairio Wetland on the eastern shore of Lake Wairarapa.
While most grants had previously gone to Wellington based organisations he added that the Wairarapa is part of the wider community supported by the Foundation.
Ross Cottle said the grant would go towards site preparation and tree planting at the joint venture project with DOC.
“We are starting to see the results of four years of effort and this injection of funds will help maintain the momentum of the project,” said Ross.
Tree planting is planned for May/June and volunteers are welcome. In past years children from Pirinoa Primary School, students from the Taratahi Agricultural Training Centre, Rotarians and DU and F&B members have assisted with the planting.
Nikau Foundation is the community foundation for the Wellington region, part of a worldwide family that provides a simple, effective and long-lasting way for people to leave a gift for causes close to their heart and close to home. Because the capital is invested and only the income is given out, the gift
keeps on giving forever.
The grant for the Wairio Wetland restoration project has been arranged by Nikau on behalf of the Richard and Doreen Evans Trust.
The Wario Wetland has come in for some close scrutiny by Victoria University Student Bridget Johnson who is this year studying towards an MSc in Ecological Restoration. The overall title of her thesis is “Ecological restoration of the Wairio Wetlands, Lake Wairarapa: vegetation dynamics and succession”.
A Summer Scholarship meant she was able to do 10 weeks of research in her chosen field at Wario with the title for that part of her research being “Temporal & Spatial Patterns of Wetland Vegetation during the Summer Desiccation Period at Wairio Wetlands, Wairarapa”. In addition to the summer scholarship, Bridget has started preparing a second site at Wairio for a large scale experimental project where around 2400 trees have been planted.
The summer study programme provided an introduction to the Wairio Wetland for Bridget where she continues the research for her thesis on factors contributing to wetland restoration. Flight, with help from Jim Law, has been able to follow Bridget’s research so far.
A poster she produced she said was just a snap shot of some of that research. “Due to the limiting size of the poster, I only talked about rare species vulnerability.” All the summer scholars got to show their posters at a poster evening. Her poster included the following information plus a number of illustrations.
Small in size, New Zealand’s native wetlands plant species are repeatedly outcompeted by more aggressive weeds. The surrounding vegetation invades when wetland plants are most vulnerable, during the desiccation (dry) period. A number of threatened low-lying plants (Pratia and Glosso) inhabit the Wairio Wetlands. To conserve these native plants a greater understanding is required of their optimal conditions and their spatial and temporal dynamics. “My aim was to investigate the temporal scale of the native species, and which abiotic factors affect their spatial distribution.”
Vegetation composition was sampled in 20 quadrants over a 10 week summer period. The quadrants were set five metres apart along two 50 metre perpendicular transects. The first transect followed a moisture gradient, whilst the other ran parallel. Additional abiotic variables were measured, such as soil moisture, soil pH, percentage open ground, sunshine hours and rainfall. Water Plantain was chosen as a comparative species as it is a common invader and an indicator of high soil moisture.
The rare species are restricted to a small band of high moisture sites. A smaller number of invasive species can grow in these moist soils, so there are fewer competitors for the natives. In drier soils, the invasive species can spread easily, giving the vulnerable natives little chance of survival. This means the natives have truly specialised ecological requirements, as their time frame of existence and habitat preference is small. This is a contributing factor to what makes them vulnerable. Further research can be expanded from this study, for example: Should water plantain (and other invasive high moisture soil species) be managed to decrease the competition on the native species? Illustrations on the poster included Glasso, Pratia and Water plantain. Glosso and Pratia grow in soil with high moisture content and Water plantain grows more abundantly in high moisture soil but is adaptable to a greater variance of soil moisture. Bridget said the native species emerge later in the summer season, whereas water plantain is a consistent species. When the natives start emerging they have a higher percentage cover than the invasive water plantain.
“I would like to thank Dr Stephen Hartley, Tony Silbery (Department of Conservation Wairarapa), Jim Law (Ducks Unlimited) and Don Bell (Greater Wellington Regional Council) for their technical support,” said Bridget.

During the last weeks of June, a band of enthusiastic Wairio Wetland members and other helpers were involved in more planting at the wetland.
The Wairio Wetland Restoration Committee met back in May and agreed the last two weeks of June would be planting time and Don Bell (GWRC) would be requested to check on Warren Field's (DOC schools Co-ordinator), availability was well as the GWRC BBQ team. Attendees were expected to be two local primary schools (Pirinoa & Kahutara), plus South Featherston and Martinborough, students from Taratahi Agricultural Training College, Rotarians, DU members & others (eg F & B members).
Jim submitted a claim for an agreed payment by Rotary for the costs of the signage at stage 1 ($450). Additionally he made a further application to rotary for the cost of weed mats ($2200). both were approved by Rotary.
Bridget Johnson, the Masters student from the School of Biological Science at Victoria University was onsite supervising the digger scraping of planting test plots.
The purchasing of trees and other materials has progressed with assistance from Don bell, Trevor Thompson (EQII) and Tony Silbery (DOC). Specialist and consistent tree planting skills are required to ensure the integrity of the research programme.
The budget for this years programme agreed at the previous meeting and additional costing data that became available as agreed is as follows:
In Previous meetings it was agreed that a budget of $2500 should be ear-marked, subject to further fund-raising and commitment by DU for resources for additional plantings in two small fenced off areas north of stage 3. An audit of their suitability for additional planting by Don, Trevor and Tony would also be required and it was hoped this could be scheduled over the next few months.
Think Big Discussion
Based on feedback from recent visitors to the wetland (Farm Forestry and DU groups), as well as growing confidence within the Committee that significant progress is being made, the possibility ofa major planting to complete stages 1, 2 and 3 in the next few years was discussed.
There was agreement in principle to this approach and as a first step an estimate should be madeof the planting required in eash stage. It is also agreed that at the same time estimates be made of what areas not suitable for planting could be bulldozed to create significant lagoons. Financial costings would be then prepared as well as estimated manpower requirements to complete the work.
Recently over 25 supporters of the Wairio Wetland Restoration Project came together to plant over 2,000 sedges,flaxes, nurse trees and specimen trees.
After being welcomed to the site and reminded by Jim Law of Ducks Unlimited of the Vision to restore the pristine wetland that had previously occupied the site, and after being briefed on the preferred planting technique by Don Bell of the Greater Wellington Regional Council the planting teams then
heard from Bridget Johnson, a Masters student from Victoria University’s Centre for Biodiversity & Restoration Ecology. Bridget’s thesis is focused on restoration work at Wairio and will compare tree survival rates and costs related to different site preparation methods and subsequent maintenance treatments. “That’s why we need the consistent planting technique, otherwise we introduce another rather random variable” said Bridget.
“The whole idea of the research programme is to introduce some scientific rigour to our restoration work” said Jim Law. “We all have our favourite ways of planting and caring for native trees but there is little, if any, science to back up what we do. Dr Hartley, Bridget’s supervisor added “We expect the results of Bridget’s research and the results from future students working at Wairio will be applicable elsewhere around the Lake and at least in the wider Wairarapa”.
So, well briefed on the Vision, planting techniques and the importance of the research programme the planting teams comprising students from the Taratahi Agricultural Training Centre, Ducks Unlimited, Forest & Bird and Rotary members, local iwi and both Department of Conservation and Greater Wellington staff headed off to plant various combinations of nurse and specimen trees in the test beds.
Then the “A” teams arrived, the environmentalists of the future from the Pirinoa, Kahutara and Martinborough Primary Schools. After being similarly greeted and briefed on planting techniques the children all headed off with their minders to plant sedges and flaxes in some soft ground near the water’s edge. “They love it and are proud of what they are doing. They also want to see further development of the wetland” said Steve Davis from Pirinoa.
Then, when the children had finished their planting, it was back to the BBQ provided by Greater Wellington Regional Council for a well learnt sausage! “Tired but happy with what they have achieved” was the consensus. The older planters also had a break at the BBQ but then had to head back to the test beds for more planting but, by the end of the day over 2,000 plants were carefully planted.
“A great effort by all!” said a thankful Bridget.
