Fabulous Fungi from Golden Bay

Dr David Orlovich, Botany Department University of Otago will be talking about the 2014 Fungal Foray to be held in May at Pohara, Golden Bay. The annual Fungal Foray always produces some interesting finds and the photos alone make attending this talk worthwhile. At the Zoology Benham Building, 346 Great King Street, behind the Zoology car park by the Captain Cook Hotel. Use the main entrance of the Benham Building to get in and go to the Benham Seminar Room, Rm. 215, 2nd floor. Please be prompt as we have to hold the door open.

Field Trip to Tavora Reserve

We'll look at the sand dune of the Tavora Reserve. This was marram-dominated, but the Yellow-eyed Penguin Trust have been planting pikao and other native dune species, which has worked quite well. We'll look at the podocarp / broadleaved forest of Goodwood Scenic Reserve, one of the very best remaining remnants of coastal forest in East Otago. The Trust have also been doing restoration planting along the stream that leads to the dunes, and along a corridor from Goodwood reserve to the sea. Leave 9 am from the Botany Department car park, return mid-late afternoon. Rain date Sunday at 12 noon. Leader Bastow Wilson, (03) 472 8999 or 021 144 8228

Field Trip to Split Rock

Split Rock is a basalt outcrop on private land to the north-east of Seacliff. It is surrounded by a highly modified podocarp/broadleaf forest remnant that supports Asplenuim hookerianum, Acaena juvenca and Pterostylis spp. in the understory. The lichen florule is interesting in that a number of predominately corticolous (bark-living) species form saxicolous (rock-living) communities. The view from the top of the outcrop across the greater Blueskin Bay towards Matakaea/Shag Point is impressive on a clear day. Wet weather plan is to visit the Truby King Reserve, in the former grounds of Seacliff Hospital. Meet 9.30 am at the Botany Department car park, 464 Great King St. to car pool, or 10 am on the corner of Coast and Russell Roads (on the scenic coastal route from Warrington to Karitane). Return early afternoon. Leader Maia Mistral, (03) 465 8299 evenings—or leave a message.

Botanical Show and Tell

This is your night to bring along items of botanical interest to the monthly meeting and talk about them. Items might include short slide shows, books, photographs, plants, or any plant-related object that has a story attached. Poems and songs welcome too. We'll also have a sale table for plants or other items you'd like to donate to the Society for sale to members. At the Zoology Benham Building, 346 Great King Street, behind the Zoology car park by the Captain Cook Hotel. Use the main entrance of the Benham Building to get in and go to the Benham Seminar Room, Rm. 215, 2nd floor. Please be prompt as we have to hold the door open.

Field trip to Gard Road Reserve, Waitaki Valley

Come and see one of our newest conservation reserves at Gard Road in the Waitaki Valley. This limestone escarpment is full of botanical treasures including rarities like Carmichaelia hollowayi, Lepidium sisymbrioides, Raoulia monroi and Muehlenbeckia ephedroides. There are also wonderful fossils to discover—all with a backdrop of the St Marys Range. Much work has already been done to remove boxthorn that threatens the cliffs and special plant habitats. We may assist with this and other conservation-related tasks. Meet 8 am at Botany Department car park, 464 Great King Street. Return 6 pm.

BSO AGM and Photographic Competition

A popular and eagerly anticipated event for anyone interested in Botanical photography. Learn what makes a good photograph and how to improve your photographic skills from our panel of expert judges. The best photographs will be chosen for the BSO Calendar so this is you opportunity to have one month of fame. Start organising your entries now and don't wait until the last minute. At the Zoology Benham Building, 346 Great King Street, behind the Zoology car park by the Captain Cook Hotel. Use the main entrance of the Benham Building to get in and go to the Benham Seminar Room, Rm. 215, 2nd floor. Please be prompt as we have to hold the door open.

Field Trip: Hands-on Botanising in the Miocene!

Three paleobotanists (Daphne Lee, Jennifer Bannister and PhD student Tammo Reichgelt) will take us to see and potentially collect fossil plants (leaves, wood and possibly amber) from Miocene forests at several sites near St Bathans. Bring suitable footwear—one site has gorse and some steepish banks to negotiate—the other two have easy walking access. Meet 8.30am at the Botany Department car park, 464 Great King St. to car pool. You will need 4WD vehicles to get to one site. We will rendezvous outside the old railway station at Ranfurly at 10 am, leaving there at 10:15 am. This is the last toilet stop before the field sites. We may be able to schedule afternoon tea at the Vulcan Hotel in St Bathans. Return by 5 pm. Bring handlens, a pocket knife, chisel or rock hammer, camera, protection from the sun and weather, lunch and plenty to drink.

Botanising in the Miocene

Jennifer Bannister is a Research Associate in the Department of Botany. She studies plant macrofossils from sites in Otago and Southland in collaboration with Daphne Lees paleobotany research team in the Geology Department. A maar lake deposit of laminated diatomite has provided a wealth of evidence for a warm temperate/subtropical rainforest in Otago in the early Miocene. Fossil leaves, flowers, pollen, fruits and insects provide an amazing window into life in the surrounding rainforest. Jennifer prepares cuticles from fossil leaves and reference leaves and uses both cuticle and leaf features to help identify the fossils. New Zealand has some of the best preserved Cenozoic plant fossils in the world, and this research is yielding exciting results, with many papers and conference presentations. It is very impressive how much one retired member with a microscope, plenty of hydrogen peroxide and much ingenuity and perseverance can transform our understanding of the past. Jennifer gave the 2013 Lucy Cranwell Lecture to the Auckland Botanical Society. At the Zoology Benham Building, 346 Great King Street, behind the Zoology car park by the Captain Cook Hotel. Use the main entrance of the Benham Building to get in and go to the Benham Seminar Room, Rm. 215, 2nd floor. Please be prompt as we have to hold the door open.

Trip to Omaui, Invercargill

Exploration of a dune and shore community with Brian Rance, DOC, Invercargill. We are fortunate to have the services of Brian as our guide as he is very knowledgeable about the plants and ecosystems of the Southland region. The walk would include the Three Sisters Dune (with several threatened plants including the only remaining mainland site of Gunnera hamiltonii (status—Nationally Critical), and 20 other threatened or uncommon species!). We could also look at the coastal turfs towards Barracuda Point. We need to leave Dunedin early to make the most of the day so meet at 7.30 am at the Botany Department car park in Great King Street. If you wish to come please contact David Lyttle so we can arrange transport.

Climate Change: Impacts on Plants and Ecosystems in the Arctic

Ulf Molau is a Professor in the Department of Biological and Environmental Sciences at the University of Gothenburg. He is also a member of the Intergovernmental Panel on Climate Change (IPCC) and one of the researchers behind the IPCC's latest report. His research documents the effects of the rapid changes happening in the Arctic and the alpine parts of Northern Swedish Lapland on the plants and fragile ecosystems, and the global implications of this. The key driver is the ongoing warming, causing a vanishing "cryosphere" detected as permafrost thawing and reduced snow cover duration, with cascading effects on hydrology and ecosystem services. Much of this is recently published in the Arctic Resilience Report, an assessment ordered by the Arctic Council (the report can be downloaded here). We are extremely lucky to have an international speaker of such high calibre to kick-start our 2014 presentations. At the Zoology Benham Building, 346 Great King Street, behind the Zoology car park by the Captain Cook Hotel. Use the main entrance of the Benham Building to get in and go to the Benham Seminar Room, Rm. 215, 2nd floor. Please be prompt as we have to hold the door open.

Field trip to Kakanui Peak

Kakanui Peak at 1528 m is one of the highest points in the Kakanui Range which runs in a north-westerly direction inland from Palmerston. We will travel to the top of the Pigroot and climb up to the summit of the peak (approximately an 800 m climb). Vegetation is mainly snow tussock grassland but there will possibly be a few surprises as the area has not been extensively botanised in recent years. For an overview of this area, including the geology and wildlife please see this PDF. Foul weather back up date Sunday 8^th December. Meet 8.30 am Botany Department car park, Great King Street.

End-of-year dinner

At Harvest Court Café, details to be confirmed at a later stage.

Variation in pollinators' view of flowers and plants

A talk by Dr John Conran, Associate Head, School of Earth and Environmental Sciences, Adelaide. Humans often assume that what we see is seen by others. This is not true and needs to be taken into account when thinking about plant pollination by insects and birds. Because of the variation of perceived light waves and ultra violet light, different species have different views of the world. For example a bees view of green foliage would be a 'real bad acid trip' for humans. Dr Conran will discuss the implications of this variation in relation to pollination in the NZ flora. At the Zoology Benham Building, 346 Great King Street, behind the Zoology car park by the Captain Cook Hotel. Use the main entrance of the Benham Building to get in and go to the Benham Seminar Room, Rm. 215, 2nd floor. Please be prompt as we have to hold the door open.

Weekend trip to Long Point

A weekend trip to this stunning Coastal peninsula in southern Catlins managed by the Yellow-eyed Penguin Trust who have great plans to restore seabird communities there. As well as the stunning coastal scenery, penguins, seals and sealions, there are interesting plant communities including coastal turfs with rare plants, coastal shrublands and forest remnants. For more information visit the website. Please note it's quite exposed so come prepared for cold and windy conditions, but hope for better. Details on where we will be staying on the Saturday evening to be posted. We will leave Dunedin 9 am Saturday 2^nd November and return by 4–5 pm Sunday 3^rd. If you would like to come, please contact Robyn Bridges.
