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 »

Talk: mapping NZ’s plants

Hooker’s spleenwort fern (Asplenium hookerianum) and its distribution in New Zealand based on specimens in Te Papa’s collection.

Next Tuesday night (27th March), I’m giving a talk at Wellington’s Otari Wilton’s Bush about how (and why) maps are generated from dried plant specimens in collections like those of Te Papa. I’ll also introduce some of the new internet tools that are making distribution information about New Zealand’s plants more readily available. Details: 7.30pm,… Read more »

Te Papa Research Fellow Patrick Brownsey and I have just described a new species of fern, Lastreopsis kermadecensis.  It only occurs on Raoul Island, which is the largest island in the Kermadec Islands group.  Hence, the second part of the new species name! The Kermadec Islands are the most northern part of the New Zealand… Read more »

In an effort to bolster our ability to identify some of New Zealand’s most widespread and commonly cultivated trees, Leon Perrie, Curator of Botany and I attended a workshop for identifying Eucalyptus, Corymbia and Pinus species this month. The workshop was presented by Chris Ecroyd, a long standing member of New Zealand’s botanical community who… Read more »

A highlight of our Fijian expedition was a trip to Kadavu, a medium-sized island south of Viti Levu.  Kadavu is a priority for Conservation International.  Four species of bird occur there and nowhere else in the world.  However, little is known of Kadavu’s bryophytes, lichens, and ferns, and it was our job to find out. While… Read more »

Ferning in Fiji

I’m lucky to have escaped the end of the New Zealand winter with a work trip to Fiji. This was as part of a Conservation International-funded, international expedition. The trip was led by Matt von Konrat of Chicago’s Field Museum, with local logistics coordinated by Marika Tuiwawa and Alivereti Naikatini of the University of the… Read more »
