At present this project will end in December 2001. Their effects should be documented over the subsequent 12 months. The results of this project raise the importance of the interactions between grazing and fire. This lies in the impact that grazing has on the landholders capacity to impose fires of a type that will have a useful impact on populations of rubber vine. Another issue that should be considered involves the interactions between weed species.
Most savanna systems are under threat from more than one weed species.
Management that targets one species may open opportunities for invasion by others. This demands that attention be given to understanding and managing 'weed complexes' that may include species of a variety of growth forms and functional responses.
