Queensland environmentalists say land intended to protect marsupials has been burnt down.

The Australian Conservation Foundation discovered greater gliders in land expected to be cleared at Meadowbank Station.

The ACF say they asked the federal government to suspend approval of the clearing, but no action was taken.

The ACF’s nature policy analyst, James Trezise, says aerial images show about 400 hectares of woodland has been burnt, including the area gliders were found.
