Authorities in South Australia have raised concerns about an increased risk of bushfires this spring as buffel grass flourishes following substantial rainfall. While buffel grass is known for its flammability and ability to outcompete native plants, it also serves as a food source for livestock.
A parliamentary inquiry has been initiated to evaluate both current and potential management strategies for buffel grass in South Australia, aiming to mitigate its spread. This decision comes amidst warnings from the Australian and New Zealand Council for Fire and Emergency Services, which forecasts an elevated fire risk in the region.
The Country Fire Service has highlighted the substantial fuel loads contributed by the rapid growth of buffel grass as a significant concern as the warmer months approach. Alison May, the CFS director of community risk, resilience, and planning, noted that while vegetation continues to grow into spring, it is already beginning to dry out. “Buffel grass has been a topic of discussion among fire response agencies for some time, and we are collaborating to determine the best course of action,” Ms. May stated.
Originally native to Africa and Asia, buffel grass was introduced to Australia in the 19th century to enhance pastures and soil quality. However, its proliferation can threaten native species and exacerbate bushfire risks. Erin Thompson, a Member of Parliament, is leading the parliamentary inquiry into buffel grass management in South Australia, marking the state as the first to officially address the issue.
“We recognize the significant damage it is causing across the state, and with the recent rains, the situation is worsening,” Ms. Thompson remarked. “We aim to assess existing management practices and identify ways to improve them to curb the spread of buffel grass in South Australia.”
James Johnston, a senior advocate at the Invasive Species Council, emphasized the urgency of stopping the spread of buffel grass. “It is essential to determine the resources needed to address this issue effectively and prioritize their allocation to protect our communities,” Mr. Johnston stated. He also pointed out that buffel grass burns at much higher temperatures than native grasses, posing a serious challenge in an already fire-prone area.
Earlier this year, the unusual rainfall patterns led to an early seeding of buffel grass, and with the approach of spring, the risk of bushfires is expected to escalate as growth continues. However, opinions on buffel grass are not universally negative. Gillian Fennell, chair of Livestock SA, argued that buffel grass serves as a valuable feed resource for pastoralists in arid regions.
“It offers essential environmental benefits, such as stabilizing creek beds and preventing soil erosion,” Ms. Fennell explained. “Buffel grass is typically the first to regrow after a drought, allowing native grasses a chance to flourish when there is another food source available. Livestock can effectively manage buffel grass by grazing on it.”
She acknowledged that in regions with higher rainfall, buffel grass might become more difficult and costly to control. However, she asserted that South Australia already has a solid framework in place to manage buffel grass, complemented by responsible land management practices from producers. “Discussions surrounding buffel grass should be approached with common sense,” Ms. Fennell concluded. “It has both advantages and disadvantages, and finding a balance is key.”
