Distribution and habitat
As well as on Kerguelen, Colobanthus kerguelensis occurs on the Crozet, Prince Edward, and Heard Islands. It has been recorded from gravel substrates in the supralittoral or sea spray zone, in well-drained peaty and sandy soils with Azorella selago, and in feldmark, up to elevations of 30 m above sea level.[2] It is a pioneer coloniser of recently deglaciated areas.[3]
