The massive biodiversity effort is part of doing better by the land, environment and people Craggy Range Vineyards relies on, says Chief Executive Michael Wilding.
“The key thing for us and the Peabody Family was, how can we continue to evolve our farming practices better and also engage with and look after our community?”
Michael says strong economic performance over the past three years has allowed Craggy Range to reinvest in its key sustainability pillars, including the roll-out of a major planting plan, increased water storage and a focus on organic production.
The company has a biodiversity programme of 100,000 trees to be planted in June this year, and another 60,000 in June 2021, from tall forests of kahikatea and tōtara to low-lying riparian areas of grasses and shrubs, interspersed with tī kōuka (cabbage trees). An artist’s impressions show the two vineyards transformed, with wide margins of native bush, and a large grove at the centre.
“This will be one of the largest biodiversity programmes in the New Zealand wine industry and hopefully an opportunity for New Zealand wine to show leadership on a global front,” says Michael.
Staff on the Te Muna vineyards are excited by the planting plan, he says. “This also allows Craggy Range to explore using carbon sequestration to offset its operations.”
It’s Craggy Range’s aspiration “to set the benchmark for biodiversity integration in New Zealand vineyards”, Michael says. “Both improving our monoculture and setting new standards for the region.”
The increased biodiversity is not only good for the environment but has led to improved wine quality, he says. “This is primarily due to increased natural yeast in the vineyard and reduced pest pressure, due to an increase in native birds.”
The winery team is hoping to work with Dr Matthew Goddard at the University of Auckland to better understand how the biodiversity plantings influence indigenous yeast in the vineyard.
Meanwhile, the company is investing heavily in water storage in Martinborough and Hawke’s Bay, to reduce pressure on rivers, says Michael. “This will mean we take our allocation in winter when the river is in full flow and reduce our summer take.”
The third tier of its environmental push is an increase in focus on farming organically, with more than 10 per cent of this year’s production, across six blocks, in organics. “We are looking to learn and to expand this programme and to continually evolve our practices,” says Michael.
The company has sought advice from specialist consultants and employed Jonathan Hamlet - ex-Chairman of Organic Winegrowers - as its new National Vineyard Manager.
