Buffel grass is an introduced perennial tussock grass, which has improved rangeland pastoral production and helped land rehabilitation. More recently, its invasive capacity has been of concern and modelling suggests that it has the capacity to expand across a large area of northern Australia. Our scoping study showed that:

aerial survey was a valuable tool for mapping presence of buffel on conservation areas;

hybridisation amongst cultivars is likely to be occurring, leading to local adaptation; and

buffel grass on rocky hillslopes did not have much effect on species composition of vegetation, birds or ants, under poor seasonal conditions.
