Biodiversity is the whole variety of all life forms – plants, animals, micro-organisms, the genes they contain, and the ecosystems they create. 

We have a special relationship with our environment. However, our biodiversity is facing a crisis. Our indigenous species and ecosystems are in serious decline.  

Around 4000 of our native species in Aotearoa New Zealand have been identified as threatened or at risk of extinction. Almost two-thirds of our rare ecosystems are threatened with collapse. Some of these native species and ecosystems will disappear forever as they are found nowhere in the world.  

Bending the curve on biodiversity loss can only be successful if we work together with mana whenua, landowners, and our communities.  

We are one of the organisations whose job it is to maintain and protect indigenous biodiversity. We also support individuals and groups to keep the momentum of their biodiversity work going. 

By working together, we'll make the biggest difference. 

Otago’s biodiversity – our ecosystems and our species

Actions you can take

Everyone can do something to help protect our indigenous biodiversity, whether it be protecting areas from further development, planting native trees in the right place, or trapping introduced predators.

Remove pest plants

Introduced pest animals are a threat to our native biodiversity. For example, rabbits can have considerable impacts through overgrazing native ecosystems or selective grazing of threatened plants; possums can eliminate preferred species by selective browsing on vegetation, causing altered forest composition and canopy collapse of palatable species, as well as preying on invertebrates and native bird eggs and chicks and compete for cavities with cavity-nesting birds; and stoats, weasels, and ferrets are mustelids that prey on native birds, amphibians, lizards, and invertebrates. Where pest animal numbers are reduced by using traps or poison, native species can recover and the health of our te Taiao (environment) improves.

Plant natives

Planting natives contributes to restoring native biodiversity by creating or enhancing habitats for birds, lizards, and pollinators, while revitalizing soils. They can filter and manage water, reducing pollution and sediment build up. As well as provide shade, help create comfortable urban temperatures, and stabilise soils, improving the ability to withstand natural hazards. Furthermore, creating green spaces through planting activities supports both mental and public health.
