Iluka owns, leases or manages a number of operational, rehabilitation and future project sites that contain areas of high biodiversity value in Australia and Sierra Leone. A hierarchy of controls – avoidance, minimisation, restoration, biodiversity offsets or other conservation actions – is followed to prevent impacts from occurring and if this is not possible, to limit their significance to an acceptable level.

The protection and enhancement of biodiversity is formalised in a range of management measures and considered within each of the planning, operational and rehabilitation phases. Biodiversity baseline studies are done by experts in the field to collect information on the current biodiversity values of a site. These values can include fauna and flora species, habitats and ecological systems present before a project commences. The baseline studies provide assessment of the biodiversity values of the site and contribute to facilitating effective mitigation of impacts and design of biodiversity management strategies. 

Operational sites have a number of management plans that build on the pre-mining biodiversity assessment. These plans include measures to control access to areas of important and protected biodiversity, controls for flora and/or fauna removal prior to disturbance, and monitoring of specific biodiversity aspects during the life of a mine. Collection of seed may occur prior to mining which is stored and/or treated for later use during rehabilitation. Similarly, vegetation on the mine path can be removed prior to mining and stored separately for later replanting use or as mulch for soil stabilisation. Management measures are also put in place to prohibit the introduction and spread of pest or invasive species especially in operational and rehabilitation areas.
