Buffel grass in South Australia: progress and future directions.
Buffel grass is arguably the greatest invasive species threat to biodiversity across the Australian arid zone. It transforms ecosystems, forming dense monocultures, displacing native plants, altering habitat structure and diminishing resources that support arid zone fauna. Buffel grass invasion negatively impacts upon aboriginal culture and increases the frequency and intensity of bushfires. In South Australia scattered populations are widely distributed across the north, with extensive infestations in the far north. The South Australian buffel grass strategic plan 2012-2017 provided a roadmap for buffel grass management and its successful implementation has seen some significant advances. Key challenges for the future are increased stakeholder engagement, improving distribution knowledge, maintaining funding and managing extensive, remote infestations.
