Phytoplankton bloom around Chatham Islands

Welcome to the Chatham Islands

Chatham oddities – the anomalous Chatham Island button daisy

Sow thistle gets a name revival and a little rusty

Last year the Chatham Islands lost one of its unique genera. The endemic Chatham Islands sow thistle was originally described by New Zealand botanist Thomas Kirk (1828–1898) as a new species of Sonchus, S. grandifolius (Kirk 1894). Then in 1965 botanist Loufty Boulos transferred S. grandifolius and the Australian endemic S. megalocarpus to a new genus Embergeria (Eichler 1965). Later Nicholas Lander (Lander 1976) transferred the Australian Embergeria megalocarpus to another new endemic Australian genus Actites leaving the Chatham Islands E. grandifolius the sole representative of the genus Embergeria, which by default was now a Chatham Islands endemic.

35 Years since the ‘extinct’ taiko was re-discovered

Bird experts and Chatham Islanders told David Crockett he was chasing a taipo (ghost), but the Whangarei man persisted, and 35 years ago this week, the taiko was re-discovered. The Taiko Trust, a local conservation organisation on the Chathams, is marking the 35th anniversary of the taiko (magenta petrel or […]
