The Martabe Gold Mine is located on the boundary of the Batangtoru Forest, an ecosystem recognised for its high biodiversity value. Although the operational footprint of the Martabe Gold Mine is very small compared to the total area of this ecosystem, impacts on biodiversity at the site are recognised by the Company as a significant environment aspect requiring careful management over the life of the mine.

Measures for the protection of biodiversity at the site include strict controls on forest clearing, detailed fauna and flora surveys prior to clearing, protection of natural waterways, a ban on hunting or trapping of fauna, and the rehabilitation of disturbed areas after mining to support a native forest ecosystem suitable as habit for local fauna. A site nursery provides native tree seedlings in support of this rehabilitation program. The Company engages with biodiversity experts and Universities in support of its biodiversity management program and contributes to biodiversity protection more broadly in the Batangtoru Forest through sponsorship of local conservation NGOs.
