Farmers' environmental credentials have been under attack of late, but new research has highlighted just one way those who work the land also strive to look after it.
Federated Farmers welcomed a study by the University of Waikato Institute for Business Research that details the impact and costs of land placed under covenant via the QEII National Trust.
Gordon Stephenson, a Federated Farmers Dairy section national chairman in the 1970s, instigated the Trust and was the first to put a covenant over part of his land.
"Farmers have been front and centre in the activities of the QEII National Trust right from the start. We congratulate them on their 40th anniversary, and for commissioning this study," Feds environment and water spokesman Chris Allen said.
When Gordon and Celia Stephenson put a four hectare stand of native bush on their farm near Putaruru under QEII covenant for permanent protection, they were not to know that over the next 40 years, more than 4300 property owners would follow suit.
