"The processes supporting the regulatory framework are weak and there is no evidence-based assurance that clearing of native vegetation is carried out in accordance with approvals," their report stated.

It also found unexplained land clearing could take two years to identify and analyse, making it difficult to minimise environmental harm or gather evidence to prosecute.

Office of Environment and Heritage figures say more woody vegetation is being cleared for cropping and grazing, up from 9200 hectares in 2013-'14 to 20,200ha in 2016-'17, while unexplained clearing of woody vegetation almost doubled from 5600ha to 10,300ha.

"Despite around 1000 instances of unexplained clearing, over 500 reports to the environmental hotline each year and around 300 investigations in progress at any one time, there are few prosecutions, remediation orders and penalty notices for unlawful clearing," read the report.

The Nature Conservation Council is now calling for immediate suspension of code-based land clearing and another "rigorous independent review". The council described the current legislative process an environmental disaster with wildlife habitat dozed and no oversight, accountability or enforcement.

In fact, those who do the wrong thing are being brought to justice. In April a Garah landholder was fined $350,000 and ordered to remediate 975ha for breaching the Native Vegetation Act after clearing 500ha of Coolibah Black Box Woodland and a Darling River aquatic ecological community over two and half years.

But not all land clearing is against the law, although all of it looks unsightly.

"Just because someone makes a complaint about land clearing doesn't mean it is illegal," says NSW Farmers' Conservation and Resource Management Chair and Tenterfield Shire councillor Bronwyn Petrie.

The debate on native vegetation is confused by data which tells only part of the story.

Like mowing a one acre block on the outskirts of suburbia, every week for a year, does not equate to 52 acres of land clearing. And yet that is how the current laws operate.

It's the same for regrowth, woody weeds, selective harvesting of native timber on private land or the clearing of failed timber plantations that are now being reverted to pasture. All these actions make up the cumulative annual land clearing figure.

"Every time invasive vegetation is removed that comes up as land clearing," says Mrs Petrie.

"There are a lot of people who read that and think new areas of vegetation are being cleared. Meanwhile there are vast areas of invasive native species proliferating in NSW while land managers wait to get sensible options to deal with it."

The new codes, introduced 18 months ago, allow block areas of woody weeds to be removed but this week the Audit Office report recommends nil soil disturbance which means farmers could only clear individual woody stems.

Mrs Petrie says she now worries that the report's recommendations will pressure Local Land Services and Office of Environment and Heritage to rush and prematurely release maps that define exempt and regulated areas.

Already there have been mistakes, like African Love grass being regarded as native pasture - which might prevent a New England grazier from planting winter oats - or even plantation avocados being classed as rainforest. These errors only create greater distrust between farmers and those driving new legislative change.

NSW Farmers Association agrees that there is a need to speed up the process of dealing with the myriad applications to deal with native vegetation. And they support increased satellite monitoring and assessment by LLS and OEH, but not a rushed release of defining maps.

"That's why we asked pre-election for $50m to better resource these new laws," says Mrs Petrie, "to speed up processing applications and compliance procedures.

"However,the last thing we need are inaccurate maps which would paralyze agriculture and distract the LLS and OEH staff."

"We've waited 24 years for better legislation but if work is stopped now while maps are fixed, OEH and LLS would require an army of staff to do that job while the processing of approvals would grind to a halt.

"Until the backlog of applications are dealt with we do not need a diversion of staff and resources with the resulting loss of trust in the process. We don't want the gate shut while we're in the process of building bridges.

"At the moment farmers are starting to trust and engage with the LLS and are looking for productive outcomes."

The need for change in this space has been obvious for some time, with a 2014 review of biodiversity legislation in NSW saying at the time that current laws created a complex system that was difficult for the community to navigate and imposed unnecessary regulatory burdens.

"The current system does not take into account social and economic considerations when determining whether clearing of native vegetation may be carried out for agricultural development.," it read.

"Almost two decades of changes to the native vegetation laws have resulted in a cumbersome and over-regulated system that is process driven.

"The regulatory system for managing native vegetation has led to some significant perverse outcomes. For example, the current way in which the Act is administered does not adequately support rotational farming and management of native grasses and seasonal practices.

"Landholders also maintain that the current arrangements are not sufficiently flexible to deal with clearing isolated paddock trees, which inhibits innovative agricultural techniques and farm productivity."

The new legislation is based on that report's 54 recommendations.

"Farmers are the only ones who can deliver these new environmental outcomes and at the moment that trust between the land holder and the likes of the LLS is coming back," says Mrs Petrie.

"Some people are determined to discredit the new legislation. But we're prepared to give it a go. Farmers need flexibility to reclaim land they couldn't control under the old act."
