The Greenbank Military Training Area (GBTA) is a large area of eucalypt forest and woodland with patches of closed vine forest, that is important for maintaining a range of old growth forest types in south-east Queensland.
Three `endangered` regional ecosystems, and one `of concern` Queensland listed regional ecosystem occur in the place. This vegetation was once far more prevalent in south-east Queensland but has been severely reduced in area due to past clearing for agriculture, forest plantation establishment and urbanisation of coastal regions between the Gold Coast and Noosa.
As a large area of intact lowland forest in the greater Brisbane region, with close proximity to more extensive bushland, the area is an important contemporary refuge for species threatened by land clearing in the Brisbane region. Species dependent on this significant habitat resource area include the plant native coleus, which is listed as endangered both nationally and in Queensland, and two fauna species the greater glider and the koala.
The flowering of canopy trees attracts high numbers of honeyeaters and lorikeets, such as the fuscous honeyeater and the scaly breasted lorikeet, and is a major feature of bird activity in the area.
The high diversity of flowering tree species within the area helps to maintain a source of nectar throughout the year and helps to sustain populations of birds that migrate through low altitude coastal areas of southern Queensland.
The GBTA provides habitat for at least seven frog species, including the tusked frog, and at least sixteen reptiles, including the eastern water dragon and the frilled lizard.
