Protecting our precious places

Mangarara Station, Central Hawke's Bay

A vision of sustainable farming - Protecting bush and wetlands and restoring the hills

Mangarara Station, Greg and Rachel Hart’s 610ha sheep and beef farm near Patangata in Central Hawke’s Bay, was the first recipient of a grant from the Air New Zealand Environment Trust.

This initiative helps communities with conservation projects and funds research into ways to enhance New Zealand's environment. When people book an Air New Zealand flight online, they are encouraged to donate to the Trust.

Much of Mangarara Station is steeper hill country, devoid of trees after more than 150 years of intensive farming.

On the flatter land, two remaining areas of native vegetation, a podocarp forest and a lake and wetland, have been protected with QEII covenants.

When Greg and Rachel took over the farm from Greg’s parents 13 years ago, they started thinking about the sustainability of farming practices.

They have a vision of the farm becoming a model of sustainable land management. Their objectives are to restore the ecosystems by planting native bush and to create a beautiful place people will want to visit to find out about farming life and restoring the environment.

‘We were looking at alternatives for more sustainable methods and approached Air New Zealand,’ says Greg.

‘They provided a grant of around $450,000 over three years to plant 85,000 trees on the farm including in a 40ha gully we have retired.

Family, volunteers and contractors have planted and mulched 22,000 native plants this year including manuka, kanuka, hebes, cabbage trees, karamu and flaxes.

'These plants will provide shade and shelter for trees such as totara and kowhai that will be planted at a later stage.’

Contractors and volunteers have placed 14,000 mats this year.

Greg has experimented with a number of different weed mats and mulches to help the plants thrive in the harsh conditions.

‘We have extremes of weather here with freezing temperatures in winter and drought conditions in summer,’ he explains.

‘It has been difficult to retain the plantings and we are now trialling mulch mats made from waste paper to control weeds and keep in moisture.

‘What we are doing here keeps me focused,' says Greg. 'It’s a challenge but the motivation is what we are going to leave for all of our children.

'A requirement of the grant is to protect the replanted block with a covenant for future generations along with the two QEII covenants on the farm.’
