Plants are essential to land and water-based ecosystems, as well as supporting the survival of humans on Earth.

Otago is one of Aotearoa New Zealand’s most botanically diverse regions. Almost half of all indigenous vascular plants occur in the region.

Over 1300 indigenous vascular plant species have been identified in Otago. From iconic tussocks to rare regional endemics like Lepidium kirkii, also known as salt-pan cress or Kirk’s scurvy grass, Otago’s indigenous vascular plants beautify the landscape and support biodiverse ecosystems. 

Otago also has a major role to play in maintaining and protecting Aotearoa New Zealand’s vascular plant life; around a quarter of Otago plants are nationally threatened or at risk.

In Otago, 39 vascular plant species are considered to be regional endemics, meaning they are native to and not found elsewhere.

In Otago we have run a regional threat assessment for vascular plants in the Region. More information can be found in a report and its accompanying spreadsheet on the regional threat assessment page.

You can also find out about our regionally endemic species in Otago on the Regionally Endemic page. We also have species list you can download as spreadsheets on:

1. Threatened or at-risk vascular plants by Territorial Authorities or Freshwater Management Units
2. Indigenous vascular plants in The Catlins Ecological Region.
