BT16170Subtropical native grasslands may not require fire, mowing or grazing to maintain native-plant diversity
The grasslands of temperate Australia seem to require disturbance to maintain species diversity. Grasslands in semiarid environments do not seem to have the same requirement. This short-term study suggests that subtropical grasslands on the Darling Downs do not have a requirement for disturbance to maintain species diversity. Drought in the subtropical environment may maintain grasslands in a sufficiently open structure to overcome the requirement for disturbance to maintain diversity of the intertussock flora.
