THE Greens are to set up a country arm of the party.

Greens country MPs will meet to discuss rural policies that they will take to the party.

They aim to meet rural and farmer groups and candidates may run under the banner of "Country Greens".

Chief of peak vegetable body AusVeg Richard Mulcahy said rural groups were "starting to see the sense of having dialogue with the party that holds the balance of power in the Senate".

National Irrigators' Council chief Tom Chesson said any engagement "has to be realistic".

Spearheading the rural move alongside leader Christine Milne is Greens NSW Upper House member Jeremy Buckingham, from Orange.

"Candidates may run under the banner of Country Greens," Mr Buckingham said.

"The key is we believe there's been an absence of engagement from the old parties. The National Party is moving away from country roots and representing the interests of miners."

The Greens have backed farmers' right to refuse mining companies entry to their land - a "lock-the-gate" policy the Nationals stopped short of.

Nationals MP Darren Chester said the Greens party was a "threat to many of our traditional industries" and had a habit of "lecturing country people from inner-city seats".

The Nationals and Greens have adopted similar positions on foreign investment and the sale of Cubbie Station, the supermarket duopoloy, coal-seam gas and biosecurity issues including the importation of whole potatoes from New Zealand.

But Mr Chester said the similar policies did not reflect "shared ideology".

"The Greens' concerns regarding coal-seam gas are based on their anti-fossil fuel mentality, whereas Nationals want the best outcome for regional people and to make sure landholders are not unfairly treated," Mr Chester said.

He said the Greens had "never created a job in regional areas" and their "lecturing" offended those involved in "hunting, fishing, horse racing and rodeos".

The Greens still had to overcome a lot of hurdles "before their efforts are taken seriously".
