A FINGAL environmental group is calling on the community to get behind it to help purchase a piece of pristine rainforest at Dulguigan to preserve for future generations.

Green Heroes, a community-based environmental education group, has already received $400,000 from a donor but is seeking to match that with funding raised publicly.

The 100ha remote property, currently on sale and teeming with wildlife, has never been cleared, save for one dwelling on the land.

Green Heroes organiser Nicole McLachlan said their plan was a bid to create a space for children in particular to enjoy the natural environment without worrying about damaging the land.

"The idea is to build a sustainable living model on the property which would act as a retreat for young people to come out and be immersed in nature and learn everything first hand,” Ms McLachlan said.

"There's been a massive amount of land clearing in Northern NSW, it's a very fragile and important ecosystem and rich in biodiversity.”

Ms McLachlan said their plan, which over time would include establishing a wildlife sanctuary complete with eco-friendly tree-houses to allow full immersion in the environment, needed the support of the community.

"At the moment we're putting a call out to donors to support the acquisition of this land, or whether it's another piece of land, as well as the financial support to build the infrastructure once the land is secured,” she said.

"The community crowdfunding campaign will be launched in the future but at this time we're at the beginning stages of it all now.”

Green Heroes organiser Andrew Cairncross said the land the group was looking to buy would be perfect for the project.

"There's pockets in here that are just amazing and the area is just as pristine as Mt Warning,” Mr Cairncross said.

Latest research conducted by James Cook University found 97% of the most species-rich places on Earth had been seriously effected by the ecological footprint left by humans.
