Pikao planting stabilises dunes

Prison-grown pikao has helped a local conservation project at Warrington Beach.

Okahau dune project organiser Angelina Young said there had been some planting of pikao about 20 years ago and although some of those plants had flourished, others had not done so well and so a project to reinvigorate the sand dune system would be a good idea.

Her first thought was planting would be slow, as starting with seedlings, plants would take more than two years to grow.

‘‘My idea was we would gather seed with the local kids and sow it and go through the whole process.’’

However, a conversation with Otago Peninsula Community Board chairman Paul Pope turned that idea on its head.

‘‘He came down and met me and got very excited about the site.’’

Mr Pope said he had been fascinated by native sand-binding sedge, also called pikao or pingao, for nearly 30 years.

‘‘I wrote my thesis on it many years ago,’’ he said.

He approached the Otago Corrections Facility, near Milton, which has a nursery on site, to ask if they would be interested in growing pikao if he provided the seeds.

‘‘They said ‘yep, sure’, so they ended up growing about 10,000 plants.’’

The inmates and staff had done a fantastic job, Mr Pope said.

Armed with 2500 pikao plants, a planting day was organised for July 10.

Local pupils and members of the community as well as University of Otago UniCrew students organised by Tash Cox took part in planting pikao in a 250sqm plot on the beach, now protected by a rabbit-proof fence.

Mr Pope contributed expertise and some funding through his consultancy company, and the project had the help and support of Kati Huirapa Runaka ki Puketeraki, Dunedin City Council biodiversity adviser Richard Ewans, biodiversity officer Aalbert Rebergen, Delta gardener Anika Jackson and Tash Cox at the Social Impact Studio.

Philip Parcell, of Tarras, donated funds to pay for transport of families and schoolchildren.

The Warrington Surf Life Saving Club opened its clubrooms for the day and local caterers Mathew Lewis and Sheena Booth provided lunch.

‘‘It is a special plant, a very special species and getting it back into the sand dunes is important,’’ Mr Pope said.

Ms Young said in the early days of colonial settlement pikao was often either burnt or grazed by herds, because with few roads, cattle were often moved along the coast on beaches.

Once sand dunes no longer had a covering of pikao, farmers noticed inland farms would be inundated with sand because there was nothing keeping it in place.

‘‘It is a keystone

species, really.’’

The project was an opportunity for local schoolchildren to understand more of the history of the area.

‘‘It is a really important zone.’’

At one time almost every sandy beach would have had pikao stands.

The native fibres were used by Maori for weaving, to create tukutuku panels, making kete (bags), and many other functional and decorative items.

Future plans were to plant at other plots along the beachfront, Ms Young said.
