Election 2017: Voting for the environment

This watercolour by Fanny Osborne of Adam’s mistletoe reminds us of its beauty.  At the time, it was known as Loranthus adamsii. It became extinct in the 1950s, probably because of forest clearance and possum browsing along with loss of pollinators and dispersers caused by introduced animals.

In the lead-up to the 2017 General Election, we have linked each of these issues to an object, or a programme, run by Te Papa. In this post, Curator Botany Leon Perrie writes about the Environment.

A highlight of my recent South Island fieldwork was helping to survey the last remaining New Zealand population of the liverwort Petalophyllum preissii.  It’s a distinctive looking plant, a bit like a little lettuce, and about the size of a fingernail. Seeing it was special because I likely won’t have the opportunity again.  You’ll probably never… Read more »

During the recent expedition to central Guadalcanal in the Solomon Islands, my job was to document the ferns and lycophytes. This was at the invitation of Marika Tuiwawa (University of South Pacific) who led the expedition’s plant team. It built on my previous experience working with ferns in Fiji, New Caledonia, Australia, and New Zealand. (As… Read more »
