Biodiversity maps and tools

The ORC has created online maps and a guide detailing the extent of Otago’s indigenous ecosystems and habitats for fauna. These resources provide native plant species lists tailored to Otago's natural ecology, helping residents restore native vegetation and habitats in backyards, farms, and local areas to encourage biodiversity restoration.
