A walk in the (paleo) woods

Don't miss this fascinating glimpse into the past. A walk in the (paleo) woods: leaves, bark, ferns and epiphyllous fungi in the 40 million year old Pikopiko fossil forest. Presented by paleobotanists Daphne Lee and award-winning Jennifer Bannister. Fossil forests are rare in New Zealand. The best known South Island example is the Jurassic forest at Curio Bay. This talk will describe the Pikopiko fossil forest, which has trees still spaced in life position exposed on the east bank of the Waiau River, near Tuatapere, Southland. At the NEW 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.

Waipori Forest fungal foray

Trip to Waipori Forest to collect fungi with David Orlovich. (Note: collecting fungi is subject to approval by DoC). Of interest is a new fungus that has only been collected once in the Waipori area. Further collections will make the description of a new species possible. Bring hand lens, small basket or bag for collecting fungi, greaseproof paper (for wrapping specimens in the field). Leave 8 AM and return to the Department of Botany around lunch time. Afternoon in the laboratory examining specimens and recording details for herbarium collections.

AGM and talk: Gardens without weeds.

Guest speaker Associate Professor Helen Leach, an anthropologist with a special interest in palaeoethnobotany. When Dr Monkhouse described Maori gardens seen in 1769 as "completely cleared of all weeds", did he mean that the gardeners were fastidious weeders, or were there just fewer weeds to eradicate? Did the Maori and other Polynesian peoples have a concept of weeds equivalent to that in European languages? This talk will look at indigenous plants that might have invaded Maori gardens, the inadvertent introduction of a small number of fellow travelers with Maori cultigens, and how different groups of Polynesians might have classified the plants that we call 'weeds'. At the NEW 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.

Rock and Pillar Range field trip

Full day or weekend field trip to the Rock and Pillar Range with alpine research botanists and ecologists. For the fit there is the option of a 3-4 hr walk up through changing vegetation zones from lowland pasture/tussock/scrub, through subalpine tussock with regenerating Hebe right up to Celmisia-dominated alpine herb fields and lichen-rich cushion fields. On-going botanical and ecological research has been based in this area for over 50 years, often using the Otago Tramping and Mountaineering Club hut, 'Leaning Lodge' as a base and refuge. See www.botany.otago.ac.nz/alpine/. There's an opportunity for those keen to extend their appreciation of the alpine flora to stay overnight, in this classic old ex-ski hut, which has been marked for destruction by DoC. Warm clothing and footwear for wet, windy conditions are advisable whatever the weather forecast. High wheel base 4WD advisable for those not walking. Some seats may be available. Contact Robyn Bridges, 479 8244 (day) if you wish to stay overnight (numbers limited).

Field trip to the Blue Mountains with Alan Mark

The Blue Mountains, although strongly modified on its lower slopes by exotic forestry, has good road access on to the summit ridge and even to its highest point at 998 m, giving easy access to a range of vegetation types, notably cushion bogs and mixed narrow-leaved snow tussock-shrubland, plus remains of a Halocarpus (bog pine) woodland exposed in eroding peat beds, all quite reminiscent of Maungatua. Its flora is also very similar but there are a few extras on the 'Bluies', notably Astelia linearis. Subalpine silver beech forest and its natural treeline at 950 m are also readily accessible. I suggested this trip as an alternative to Maungatua, given its easier (and more reliable) access. Note, however that there are some steep sections and it is advisable to take vehicles capable of handling rough terrain. It has been much less studied than Maungatua but was included by Stephan Halloy in his comparative study of alpine plant morphology (J. Veg. Sci. 1: 291-304. 1990: J. Roy. Soc. NZ 26: 41-78: 1996). Warm clothing and footwear for wet conditions are advisable whatever the weather forecast.

The All Taxa Biodiversity Inventory being carried out in the Great Smoky Mountains National Park

A talk by Steve Stephenson, Research Professor in the Department of Biological Sciences at the University of Arkansas. Steve has recently completed a volume in the Fungi of New Zealand series on plasmodial slime moulds (myxomycetes). He has been surveying mycetozoans (protostelids and dictyostelids as well as myxomycetes) as one component of an all taxa biodiversity inventory (ATBI) of the Great Smoky Mountains National Park. The ATBI of the Great Smoky Mountain National Park in the US has resulted in the discovery of 136 species new to science, in the Park, and an additional 1,436 that are known species, but which have not been previously identified as occurring in the In addition there is much new information on the geographic distribution of thousands of species, important for maps of species distribution. The inventory, coordinated by a support group called Discover Life in America, is conducted by scientists, student volunteers and others from all over the United States. See this article from the Smithsonian Institute for more background information. At the NEW Zoology Benham Building, 346 Great King Street, behind the Zoology car park by the Captain Cook Hotel.

Closing date for Audrey Eagle Prize for Botanical Drawing

Entries may be given to Audrey to take home for judging at our evening meeting on 8 March. Any medium is permitted, colour or black and white. The main criterion is that it has a botanical theme. Audrey suggests that something that has not been fully illustrated yet, like a small herbaceous plant, a lichen or a liverwort would be of added botanical interest. The president would love to have colour pictures to feature on our website, the committee is keen to have something we can use as a logo or letterhead, while the editor will be delighted to have original art to feature in the BSO newsletter, especially if there is an interesting note to go with it. (Bear in mind that the newsletter is set out in 14 pt font on A4 pages, which are photocopy-reduced to A5 for publishing in black and white.)

Start of Semester BSO BBQ!

A BBQ to welcome new botany/ecology students and new BSO members. On the front lawn, Botany House Annexe, Great King Street (across the road from the Caltex). Sausage sandwiches and juice $1 each. All BSO members welcome!

Mycorrhizal fungi - ubiquitous underground partners of plants

A talk by Prof. John Cairney, from the University of Western Sydney. Prof. Cairney is an expert on the population ecology and ecophysiology of mycorrhizas and mycorrhizal fungi. He is visiting Dunedin during February 2004 as a William Evans Visiting Fellow. The majority of terrestrial plants exist naturally in symbiosis with mycorrhizal fungi, a form of mutualistic interaction that is thought not only to be important in enhancing the ecological fitness of individual plants, but also in shaping plant populations and communities. This talk will provide an introduction to these fascinating associations, with emphasis on the ecology of the fungi that form mycorrhizas with trees and epacrids. At the NEW 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.

Tokomairiro Mouth with Janice Lord

Grade easy - suitable for all ages. First stop will be the Lower Tokomariro Wetland. This QEII covenanted area is managed by Fish and Game for waterfowl. No formal assessment of the vegetation exists and Fish and Game are very keen for any information we can provide. Fernbirds are often sighted here. The main area to be visited is the dune complex to the south of Toko Mouth settlement which supports probably the largest pingao population in Otago and numerous other native species in dune slacks. Hot water etc is available at Janice's crib. Bring lunch and suitable beach, sun and rain gear. A hand lens is recommended. Return to Dunedin, approx. 5-6 pm. Field trip leaves from Botany car park 464 Great King Street. Meet there to car pool (10c/km/passenger, to be paid to the driver, please).

Mt Watkin podocarp forest

Trip leader: Ralf Ohlemüller. After recent trips to the area of Mt. Watkin north of Dunedin and the discovery of its significance for a number of rare species (see BSO newsletter 38), we will now have a closer look at the forests near the 'bottom' of this remarkable volcano. These sheltered forests in the gullies running off Mt Watkin harbour a wide range of mature specimens of podocarp, such as matai, rimu, totara and kahikatea - rare remnants of the magnificent lowland forest that once clothed much of eastern Otago. Ralf has studied species richness patterns in forest fragments in coastal Otago and also tried to reconstruct the potential natural forest vegetation of the area. He will talk about his work on the day. We will be walking off track, so bring solid shoes, outdoor equipment, rain gear and lunch. A hand lens is recommended. Return to Dunedin, approx. 5-6 pm. Meet 9 am, Botany car park 464 Great King Street to car pool (10c/km/passenger).
