LEDA, the developer of the proposed Kings Forest township south of Kingscliff, has refused to comment on allegations in the NSW Parliament that it is responsible for illegal clearing work in the Cudgen Nature Reserve.

Greens MP Cate Faehrmann has told the NSW Upper House "it appears" that Leda may now be clearing vegetation in the nature reserve in addition to clearing approved on the Kings Forest site.

She claimed Leda has "a history of illegal vegetation clearing" and called on the NSW Government to consider "changing the law to ensure that developers with a history of non-compliance with planning and environment laws be precluded from further development approvals".

Regional manager for Leda Reg van Rij said the company, which is headed by development billionaire Bob Ell, did "not wish to respond".

Ms Faehrmann said she visited Cudgen Nature Reserve on October 6 after local people told her about "the illegal clearing of 300 metres of vegetation within the nature reserve on the banks of Blacks Creek".

"The area cleared is adjacent to the Kings Forest residential development," she said.

"Suspicion has turned to the developer of the Kings Forest site.

"Bob Ell has a reputation for getting away with many other instances of native vegetation clearing and habitat destruction."
