The Botanical Art and Illustration Courses at Olveston began in January 2017. An Advanced Botanical Art and Illustration Course was later held beginning June 2018 and out of that course came the first Botanical Art and Illustration Exhibition at Olveston, which was held in December 2018. The classes have been hugely popular. The exhibition of original botanical artwork was of very high quality and created great public interest.

The courses are taught by Wayne Everson, who is an award winning teacher and practising artist. He holds a Master of Fine Art degree from RMIT University, Melbourne, and has taught art at tertiary level for many years in New Zealand and overseas. Wayne Everson will give the talk, which will centre on the success of the classes at Olveston and their botanical focus. 1c.jpg

Akatore is a remnant of diverse coastal shrubland at the mouth of Akatore Creek, 45 minutes south of Dunedin. Some special features of this site include the diversity of shrub species and threatened species such as Coprosma obconica, Olearia fragrantissima, Melicytus flexuosus and Carex littorosa with the possibility of our discovering other threatened species. We may also visit the adjacent coast where the threatened cress Lepidium tenuicaule is present as well as Myosotis pygmaea. It is recommended to bring extra foot wear to change into in case they get wet!

Speaker: Hamish Campbell (Emeritus Scientist, GNS Science). Location: Castle 1, University of Otago (drinks and nibbles starting from 5:15 in the concourse).

This is an illustrated talk exploring the geological evidence for the emergence of land and onset of terrestrial conditions in New Caledonia (northern Zealandia) in the Oligocene, and in the Chatham Islands (eastern Zealandia) in the Pliocene. These age interpretations have significant implications for our understanding of the antiquity and biodiversity of the floras of both New Caledonia and the Chatham Islands.

Unfortunately, Toni is not longer able to speak this Wednesday, so David will be giving us a talk instead.

Dr David Orlovich, Department of Botany, University of Otago

Through many wonderful collaborations, we have been using new genomics tools to explore the past, present and future of our native forests and the fungi that support them. We used genotyping by sequencing to study the population genetics of silver beech. I will give an update on our research that gives tantalising clues to how silver beech spread in the South Island following the last ice age. However, beech trees can’t grow on their own, and we are also discovering many new species of ectomycorrhizal fungi that help beech trees to grow. The distribution of these fungi is still poorly understood, and again, new genomics tools will come to the rescue. We aim to understand if barriers to beech tree dispersal are also barriers to the spread of fungi. Watch this space! Finally, whole genome sequencing is allowing us to understand the genetic basis for the incredible diversity of mushrooms and truffles in our forests, and I will give an update on our research that seeks to understand the mechanisms that give rise to so many truffles in the NZ bush.

Speaker: Laura Van Galen. The symbiotic relationship that exists between beech trees and ectomycorrhizal fungi has important implications for beech forest regeneration and the stability of forest boundaries. I am doing a PhD to investigate this relationship and provide practical information to assist forest restoration projects. I am conducting a large-scale survey of ectomycorrhizal fungi in beech forests across the South Island of New Zealand, to better understand the influence of host species, soil properties, patch size and condition, and other environmental factors on ectomycorrhizal diversity and community assembly. I am also establishing a plot experiment in ex-pasture where beech seeds will be sown under varying conditions, to determine the relative importance of fungi compared to other factors (such as soil nutrient levels, grass competition, the availability of shelter and herbivory) for restoration project success.

Please note the new date.

Okia Reserve is a large coastal reserve on the Otago Peninsula that is jointly owned by the DCC and Yellow-eyed Penguin Trust. It comprises an old dune system that is rapidly changing from its dominant bracken cover to woody coastal species. The hollows between the dunes hold a variety of wetlands that include turf, bogs and ponds. The Otago Regional Council regard the dune hollow vegetation to be the best example in the Otago Coast Ecological Region. Along with the Pyramids - a significant geological feature, and Victory Beach - the longest beach on the Peninsula, there's plenty to keep us occupied. We'll do a walk that encompasses all these features. Meet at Botany Department carpark at 9am or the Okia Reserve carpark at the end of Dick Road at 9.30 am.

Fungal Foray to Knights Bush, led by keen mycologist Andy Nilsen. This forest bordering the Clutha River at Tuapeka West has many different ecosytems to explore. Plantings of macrocarpa, pine, eucalyptus and Douglas fir grow on the edge of a diverse area of native forest. Inside the forest are stands of old kanuka, silver and mountain beech, ancient totara and matai on the shady slopes, with mixed podocarp/broad leafed forest on the river flat and a kowhai/korokia/divaricating shrub mix on the sunniest slopes. A list of known fungi from the area will be circulated and there will be a prize for the person who adds the most new species to the list! Meet at the Botany Dept car park at 8.30 am to carpool. 4WD to cross the access paddocks and footwear with good grip for the steep slopes recommended. Be prepared for all weathers. Contact Allison Knight 027 4878265.

This is a family run restoration project of a the wetland and forest remnant. The project has been going a number of years now and been quite a bit of success with reforestation, increased birdlife and pest eradication. Recently they hosted the bird watching society who assisted them greatly with a bird count and a list of birdlife in the wetland and native bush. Now the Greens have asked the BSO to help create a plant species list for the native bush. We will spend the day exploring the tracks around the bush and wetland to compile a species list. Meet at Botany Department carpark at 9am. Contact Gretchen Brownstein 021 065 8497 or brownsteing@landcareresearch.co.nz.

Speaker: Maia Mistral.

Willows introduced to New Zealand can be subject to bad press. Often neglected in the debate are willow species that humans have depended upon for centuries for their high utility values. One such group of willows selected over time specifically for their flexibility and amenability to cultivation are referred to collectively as basket willows. For those interested in learning willow basket making or considering it as a vocation, a lack of access to suitable willow can be a major barrier to progress. In fact, securing a reliable supply of raw material has been an ongoing concern even amongst professional willow basket makers who first began to work in New Zealand from the mid-19th century. This talk will use insights from the past to discuss the relative value of importation, wild harvesting and traditional coppice management of selected basket willow varieties as pathways for securing material supplies in the future.

We will start off at Smaills Beach where we will look at dune and coastal vegetation. We will then go to the top of the Karetai Track where there is an extensive area of Veronica elliptica shrubland and associated coastal plants including Linum monogynum, Pimelea prostrata, Samolus repens and Epilobium komarovianum. This is your chance to see some spectacular coastal and clifftop scenery. Depending on the time available there is the potential to visit several other sites. We shall return to Centre Road where we will look at a newly intitiated conservation planting project on a piece of fenced bush on the property of Mr Donald Lyttle.

Following the field trip there will be a barbeque at 189 Centre Road to which all participants are invited. Meet at the Botany Department carpark at 9.00 am. If the weather is unsuitable we will hold the trip on Sunday 17th.
