Nature and biodiversity
Biodiversity is critical for healthy ecosystems, food security, clean water and resilient communities.
Caring for country and nature has been central to Aboriginal, Torres Strait Islander and Māori culture for thousands of years, and we respect these deep connections in how we plan and deliver projects. Downer recognises that our activities can affect biodiversity, and we manage this through our Environmental Principles, the biodiversity mitigation hierarchy (avoid, minimise, restore, offset), and strong governance.
Flora and fauna
Before works begin, ecological assessments identify key species and habitats. Where significant biodiversity is present, we collaborate with regulators, landowners, Indigenous partners and experts to design management plans. These plans may include conservation monitoring, threatened species protections, revegetation or relocation, ensuring impacts are avoided or minimised wherever possible.
Biosecurity
Downer manages biosecurity risks such as invasive weeds, pathogens and animal pests, which can be introduced through project activities or equipment. We implement controls across all sites to prevent their spread, working with regulators and landowners and applying monitoring and inspection regimes. These measures protect ecosystems, agriculture and communities from long-term harm.
