Plant collecting in south Canterbury and Marlborough

On our first collecting day, we set a new elevation record for Te Papa’s new 4WD, with 1100 m on Mount Studholme near Waimate.  We smashed that with 1700 m on our last collecting day, on top of Marlborough’s Black Birch Range.  The snow-capped Tapuae-o-Uenuku of the Inland Kaikoura Range is the backdrop.

An important function for Te Papa’s natural history collections is to document the plants and animals we have in New Zealand. What species are present, how can they be distinguished, and where do they occur? These questions need addressing before our biodiversity, both indigenous and exotic, can be managed in an informed manner. It is… Read more »

Bolstering local plant populations through propagation

Muehlenbeckia astonii SinclairHead 10_reduced

Increasing plant populations through propagation is one way to help threatened species.  Last week, Wellington City Council biodiversity staff collected cuttings and seed from several plant populations in the Te Kopahou area on the coast south of Wellington.  I tagged along. The targeted species Spectacular, steep habitat Wellington’s south coast is a spectacular landscape, and… Read more »

Today is World Habitat Day and this week is World Space Week. I’m observing both of these events by databasing bryophyte (moss and liverwort) botany specimens which are habitat for space travellers. Bryophytes are among the ‘preferred’ habitat for microscopic animals called tardigrades, otherwise known as waterbears or moss piglets.  Although, tardigrades aren’t that fussy about… Read more »

How many plants are in New Zealand?

  • The fork fern Tmesipteris tannensis is indigenous to New Zealand, being present here without human intervention. Moreover, it is endemic, being indigenous to New Zealand and nowhere else in the world. About 45% of the indigenous ferns and 80% of the indigenous seed plants are endemic to New Zealand.

  • Stereocaulon ramulosum is a common New Zealand-indigenous lichen. I suspect few New Zealanders would know it, which is symptomatic of the attention given to lichens, even though they contribute significant biomass to many ecological communities. Photo Leon Perrie CC BY-NC.
  • African club moss (Selaginella kraussiana) is an introduced lycophyte (and not a moss). It is very invasive, even into relatively undisturbed indigenous forests. It carpets the ground, suppressing the regeneration of indigenous plants. WELT P026410. Photo Leon Perrie. © Te Papa CC BY-NC-ND.
  • Anyone visiting New Zealand’s coast is likely to have seen Neptune’s necklace (Hormosira banksii). It is a very common, indigenous brown seaweed. But many New Zealand seaweeds are only poorly known. Photo Leon Perrie CC BY-NC.

I gave a talk on “Understanding and valuing our plants” at the recent open day of Otari-Wilton’s Bush in Wellington. I’m very interested in why New Zealand’s native species might be valued. I am hoping you can help me think about that – I welcome your input; look out for an upcoming blog post. But… Read more »

Celebration of personal milestones in the Botany collection

Collections are at the heart of a museum. A museum’s exhibitions and research are built from its collections. The significance of collections means it is important to acknowledge those who have contributed. Te Papa’s Botany collection of plant specimens has recently seen notable milestones for two of its biggest contributors: Research Fellow Patrick Brownsey and… Read more »

Ko te whānau o Matariki: Matariki Education Resource 2015 – Part 3

Orion and the Milky Way by jpstanley,

In Part 1 and Part 2 of this resource, we were introduced to Matariki and her six daughters – learning how each star plays her own special part in preparing the environments of Papatūānuku for the New Year. In this final section, we will be introducing three of Matariki’s cousins: Puanga/Puaka, Pūtātara and Hine-takurua. Papatūānuku has entrusted these whetū kanapa (bright stars)… Read more »

Botany Collection Narratives (Part 4): Expedition Snares Islands

Caption: A new moss record for the Snares Islands - Tayloria purpurascens! Te papa collection item M041684. On the right you can see the leafy gametophyte (gamete plant). And on the left, the stalk-like structure is the sporophyte (spore plant) which develops from female reproductive organs on the gametophyte. (Field of view c. 4cm)

Back in December 2013, four Te Papa Scientists ventured into the deep south on a 15 day expedition to the Snares Islands. Some of you may remember earlier Snares blog posts and you tube videos from this excursion. In order to provide a quick reference resource on Snares Islands botany I recently completed some Expedition Snares… Read more »
