BUSH TUCKER AND BIODIVERSITY: WEED MANAGEMENT ON THE FLOODPLAINS OF KAKADU NATIONAL PARK

Invasive alien species are a major driver of global biodiversity loss. Constrained conservation budgets demand that threat abatement strategies must take into account the heterogeneity of areas in need of protection, such as significant ecological and cultural sites, as well as the competing values, preferences and objectives of stakeholders. We used an interdisciplinary team to assess the threat that invasive alien grasses pose to both environmental and Indigenous cultural values on the floodplains of Kakadu; a co- managed, World Heritage-inscribed national park. We evaluated costed management scenarios that sought to simultaneously conserve biodiversity and bush tucker. We found that there was a greater initial cost to protect both bush tucker and biodiversity sites comparted with just protecting biodiversity, but the ongoing costs were similar. This was the first study to apply strategic foresight to weed management planning in a realistic, culturally complex setting and it provides Traditional Owners and park managers with a basis for improved floodplain weed management.
