Queensland's Labor government and environmental groups have blamed the Liberal National Party for increased tree clearing in the state, but the opposition stresses the figures don't add up.
The Statewide Landcover and Trees Study showed 395,000 hectares were cleared across the state in 2015-16, an increase of 100,000 hectares.
Deputy Premier Jackie Trad said the findings were "worse than my worst fears" after the government tried to introduce laws to restrict tree clearing, which were blocked by the LNP.
"Both in government and in opposition, the LNP are clearly saying to landholders that it is open slather when it comes to bulldozing native trees and vegetation here in Queensland," she told reporters on Thursday.
Ms Trad said changes were urgently required, and if Labor won the coming state election they would again introduce almost identical laws.

Tim Seelig from the Queensland Conservation Council, said the situation was "almost all the LNP's fault".
"We knew when the laws were weakened (by the LNP government) in 2013 that this would be the consequence," he said.
"Our native wildlife is being smashed here, we're losing species like the koala, and loss of habitat is the single biggest cause of loss of biodiversity in our state."
But LNP Natural Resources spokesman Andrew Cripps questioned the figures contained in the report.
"Labor has deceptively included practices such as fodder harvesting to feed starving livestock and clearing firebreaks and fence lines as 'broad scale land clearing' in a deliberate attempt to inflate clearing figures," Mr Cripps said in a statement.
"About 50 per cent of Queensland is covered by woody vegetation, so the vegetation management activities in this SLATS report represent just 0.23 of the state - less than half of 1 per cent."
Environment Minister Steven Miles said tree clearing in catchments of the Great Barrier Reef had increased by almost 50 per cent since 2012-13.
Dr Miles said the clearing around the Great Barrier Reef exacerbated environmental problems around the natural wonder and put it further at risk.
