There are currently five recognised species of fern on the Snares Islands, the closest sub-antarctic island group to New Zealand. North East Island, the main island of the Snares group, slopes gently downhill from the tall, tussock covered western cliffs towards the forested east coast, creating four small catchments, which drain into
The vascular flora of the Snares Islands is limited, at only 22 species (including one hybrid Poa). Despite this, my first impression of the main island was an island covered with lush vegetation. And there are still some botanical challenges – we failed to locate the fern Histiopteris incisa for instance.
