Jacinth-Ambrosia – Rehabilitation

The Jacinth-Ambrosia operation in the Eucla Basin of South Australia is the first mining and processing operation to be permitted in the State in a mixed use regional reserve – the Yellabinna Regional Reserve.

Mining is allowed under a multiple use framework that approves natural resource development alongside the reserve’s primary role of biodiversity conservation.

Jacinth-Ambrosia is located within an arid environment and is dominated by chenopod, or salt tolerant, shrub land plains and open myall woodlands interspersed with myall woodland species and mallee (a Eucalypt species) within an environment of sand rises and creek beds, which are dry for the major part of a year.
The reconstruction of an arid environment similar to that at Jacinth-Ambrosia is a challenge faced by Iluka’s on-site rehabilitation team. Consideration needs to be given to a number of aspects including the appropriate storage and reconstruction of soil profiles, stabilisation of newly rehabilitated areas, re-establishment of plant species that do not readily germinate from soil seed banks and revegetation within an environment of minimal and unreliable rainfall. In addition, limited knowledge is available on the ability of some key local plant species, including the western myall tree, to survive or re-establish in an altered environment.
In order to understand how the environment at Jacinth-Ambrosia may recover from disturbance, the rehabilitation resources at Jacinth-Ambrosia worked in collaboration with research scientists at the University of Adelaide and the Adelaide Botanic Gardens. Knowledge gained from the research collaboration and on-site monitoring programmes has been valuable feeds for rehabilitation planning and implementation activities at site.
