A plan for a shared food forest in Canberra's north is a step closer, with the Government asking for feedback on the idea.

If the project gets the go ahead, about 30 fruit and nut trees would be planted on land behind the Lyneham Primary School which would be looked after by volunteers.

Anyone would then be able to pick from the trees.

Meg Clark from the Lyneham Commons Organising Committee said there was already a lot of interest in the project.

"We've got about 90 people on our list that we have already signed up to say they really want to support it," she told 666 ABC Canberra.

"When we asked what skills or interest they had, half of them want to dig or want to shovel, so I think now we're getting nearer to the phase of being able to do that, some of those people might become more active in the group."

Ms Clark said the committee had been working on the plan for 18 months and know what they want to achieve.

"To take public land and to add value to it as a resource for the community to enjoy working together on, but also to increase urban food growing in the city," she said.

"We wanted it to be land that had a fairly low-use value that we could really add value to."

Ms Clark said the project would also aim to use permaculture principals.

"Each tree is part of a guild where the understorey has plants that support it through either pest control, soil improvement or bearing fruit themselves," she said.

"It's not a monoculture so eventually there'll be food both at a tree level and the understorey level."

Minister for Territory and Municipal Services (TAMS) Shane Rattenbury said the proposal was an exciting new idea.

"We've certainly had community gardens in Canberra before, but the idea of doing this common orchard is a new one," he said.

"It's very exciting in terms of the intent to plant complimentary plants so there's a minimal use of pesticides, but so that pests and diseases are controlled."

Mr Rattenbury said it was great to be able to support a local community initiative.

"The idea for this project has come from the community, they've built this up over the past couple of years," he said.

"There is an enthusiasm in the community for growing more food locally.

"Certainly I'm keen to assist with that and TAMS has a fair bit of open space."

The community can provide feedback on the proposal until June 8.
