Digging into the roots of New Zealand’s golden opportunity

Scientists and Māori agribusiness have teamed up to learn about mānuka DNA variation, beehive stocking rates, and honey bee food resources.

As the mānuka gold rush continues to soar, so does New Zealand’s honey bee population.

There are now more than 875,000 registered beehives across the country, twice as many as 15 years ago.

But coinciding with the industry boom, are questions about honey bees’ food resources, mānuka variation, and how to reduce hive losses.

With the majority of New Zealand’s natural mānuka populations growing on Māori-owned land, Māori agribusiness has teamed up with Manaaki Whenua – Landcare Research scientists, Plant and Food Research, and the University of Waikato, in a 5-year project that sets out to answer these questions and best maximise this opportunity.

“We commonly refer to it as the Honey Landscape, and really it’s about trying to understand how many hives we can have out on the landscape,” says Manaaki Whenua – Landcare Research scientist, Dr Gary Houliston.

The Honey Landscape aims to create a comprehensive model of New Zealand’s native honey landscape, blending science and tikanga Māori to help Māori landowners increase honey production while still sustainably managing the native mānuka and plant species.

“We want a tool that a landowner can use to assess their property for how many hives they can actually place there. They would take our tool, consider what is on the land, look at what sort of vegetation they have, and assess how many hives they’ve got or can actually run on the land without experiencing the loss they are having,” says Dr Houliston.

The project starts by digging deeper into the roots of native mānuka growing on Māori land.

Researchers are working with Māori landowners to collect leaf samples from natural mānuka stands, extract the DNA, and see how mānuka varies in genetic makeup across a landscape and region.

“A lot of research has been done on the honey. Not a lot of research has been done on the actual resource itself,” says Ngati Porou’s Victor Goldsmith.

The sudden increase in international mānuka honey prices in the last decade has encouraged large commercial entities to jump in on the gold rush, but at a rate that food resources and honey bees can’t sustain.

While there are stocking rates for beef and sheep farming, there are none for beekeeping.

Without a stocking rate model, hundreds of hives can be placed on neighbouring properties, which results in bees being overcrowded, causing disease to spread faster and ultimately kill more honey bees – something researchers hope to change.

“We lose about 10 per cent of the hives each year, and this is partially due to overstocking – the bees basically don’t have enough food and don’t produce any honey or they consume all the honey in the hive,” says Dr Houliston.

“But if you understand what that stocking rate can be, we can possibly maximise the return from the number of hives and the amount of honey you are getting out of each hive,” he says.

With the competition in the New Zealand mānuka honey industry now the highest it’s ever been, a deeper understanding of the mānuka variation in each region is something Māori industry groups hope to use to help market their unique product.

“While we have a really good story that can sit behind our province story that we would be able to tell people overseas, especially if they are buying some of our mānuka honey products, I need to be able to back that up with some western science,” says Goldsmith.

“If we have the DNA work done, the DNA is DNA, so you can’t argue with that. At the moment, it looks as if some of those mānuka strains are different from others, which is really exciting.’

Over the project, researchers will also collect and test samples from other common honey bee nectar and pollen resources, to have a deeper understanding of what’s being collected across an entire piece of land.

New Senior Leader at Manaaki Whenua
We are delighted to announce that Graham Sevicke-Jones will be joining the Senior Leadership Team at Manaaki Whenua ­– Landcare Research in the role of General Manager Science & Knowledge Translation. Graham will start his new role on 25th March, and will be based in our Wellington office. He fills the vacancy left by Justine Daw’s move to GNS Science.
Graham will bring his extensive experience of applying science to real-world challenges faced by communities, businesses and government agencies seeking the sustainable use and development of our natural assets in New Zealand. He has deep experience of this from working at Canterbury, Hawkes Bay and Greater Wellington Regional Councils and currently Southland Regional Council, where he is Director Science and Information.
Alongside Dr Pete Millard, General Manager Science, Graham will be responsible for our research and science portfolios, but with a particular focus on the needs and opportunities for knowledge translation. He joins at a time when the translation of knowledge from science is increasingly demanded and the technologies for this are increasingly available. For us, knowledge translation is not merely the one-way communication of science; it is a two-way process of ensuring stakeholders’ perspectives and needs are understood and our science plays its role fully.
Graham’s experience in working with communities and understanding the people side of decision-making is also going to be very valuable as Manaaki Whenua continues to emphasize the integration of social and cultural, economic and environmental dimensions.  Graham says, “I am especially interested in providing the information base to enable community values and aspirations to be realised whilst providing for a resilient and healthy environment.” He recognises the roles of behaviour change, systems thinking, collaborative processes and Mātauranga Māori knowledge systems.
