Plant Conservation Conference and weedy native plants

Pittosporum crassifolium (karo) is native to the northern North Island. However, it has been widely cultivated, and is now spreading aggressively in many places. In Titahi Bay, karo threatens to displace locally-native species, including some of conservation significance. In the photo, karo is overtopping, and will eventually displace, the locally-native Melicytus obovatus. Photo Leon Perrie. © Te Papa

I’m just back from the 2013 conference of the New Zealand Plant Conservation Network, where I presented a talk about weedy native plants. The programme of talks included updates on the conservation status of New Zealand’s plants, and the new system being implemented by the Department of Conservation to prioritise management of ecosystems and species….

Would you mine a rare population?

The Escarpment Mine on the Denniston Plateau has been tentatively approved by the Environment Court, subject to suitable mitigation plans. One of the issues that may be under consideration is what to do about the site’s population of the Sticherus tener umbrella fern. Scoop news report: “…tentative nod for Denniston mine plan”. Sticherus tener has… Read more »

The amazing longfin eel

This week the Parliamentary Commissioner for the Environment released a report on the status and management of the longfin eel. It was entitled “On a pathway to extinction?” The report found that the management of longfin eels by New Zealand government agencies was inadequate and failing. It further recommended the cessation of commercial fishing of… Read more »

Help with floating fern

Azolla plants often become red in full sunlight, and they can become so abundant that they carpet ponds, drains, and other still bodies of water. This is Azolla filiculoides in a pond on Mana Island, Wellington. Photo Leon Perrie. © Te Papa.

I’ve recently learnt that the introduced Azolla pinnata (ferny azolla) has been found in the Wellington region. I’m interested in its distribution and would be grateful for help in looking for more. Azolla plants are fairly easy to spot: look for a red plant covering still bodies of water. Azolla are ferns, believe it or… Read more »

by Matariki Williams A highlight for me in Kahu Ora is a kākahu that is in the process of being cleaned by Textile Conservator Anne Peranteau. This kahu kurī is from between 1750 and 1840, of unknown provenance, and is made from strips of the pelt of a kurī (Polynesian dog) sewn onto a finely twined foundation… Read more »

Caring for our photographic negatives

  • Cellulose acetate film was used for negatives from the 1920s.  It tends to break down to acetic acid, causing the film to shrink.  This makes the binder layer form channels and spots, and the image becomes difficult to read.

We have an enormous collection of photographic negatives and transparencies on glass and film, going back to the 1870s. They include all sorts of images from studio portraits to holiday snaps, landscapes, photographs of sports teams, and artists’ negatives and transparencies. Many negatives are chemically unstable and, if left in an uncontrolled environment, will deteriorate to… Read more »

West Coast Fern Fieldwork 2012, 1 – what we were doing

Gleichenia ferns often grow entangled with one another and with other plants; hence their common name of tangle ferns.  But our understanding of them is also in a tangle.  Two or three species are currently recognised in New Zealand, but I think there are at least five.  The picture is of a new species.  It looks similar to the others from above, but very different when viewed from below.  I hope to formally describe it in a year or so.  Then I will be able to show you the differences.  Our fieldwork significantly extended the known occurrences of this fern.  Photo Leon Perrie. © Te Papa.

I’m just back from 10 days collecting ferns in the South Island’s West Coast. From previous collections, we knew of several currently unrecognised species of fern that occur on the West Coast. We investigated these records, visiting the sites to collect more material for our studies and to assess the plants in the field, including… Read more »

The exchange with the Institute in Tokyo is part of a programme of work to… Read more »

I awoke on the morning of 6 March to discover that we had very rapid progress over night and were approaching the rugged columnular basalt cliffs of the Antipodes Island, crowned with green tussocks. The home to the Antipodean albatross,the Antipodes Island parakeet and the erect-crested penguin (to name just a few of the birds!)…. Read more »
