The dates for this year’s It’s All About the Plants seminar series have now been fixed. The talks will again take place in the Botanic Garden’s Goodman Building Lecture Theatre (Hackney Road, Adelaide) on the first Tuesday of every month from 10:00–12:00, except July, August and December. In August, the State Herbarium of South Australia plans a mini-symposium to celebrate its 60th anniversary.
The following speakers have agreed to give talks in 2015:
14 Apr. — Ed Biffin (State Herbarium)
5 May — Alexis Tindale (South Australian Museum)
June (TBC) — Teresa Lebel (National Herbarium of Victoria)
8 Sep. — Jose Facelli (The University of Adelaide)
Nov (TBC) — Doug Fotheringham (State Herbarium, our newest Hon. Research Associate)
Come and hear how an excavator can be used for positive outcomes in large- scale aquatic plant restoration.
The aquatic plant, Ruppia tuberosa is a key primary producer in the Coorong, providing food (foliage, turions, seeds) for waterbirds, and habitat for fish and invertebrates. During the millennium drought, the population of R. tuberosa in the Coorong was severely depleted, including its seed bank. Therefore when improved water conditions returned, the plant was not able to respond quickly without intervention. Continue reading →
Please note that Dee Provis’ seminar about the Mudalla Primary School Herbarium Project has been shifted from next Tuesday
to Monday, 15 December 2014, 2:00pm–3:00pm. The talk will now take place in the afternoon.
Detailled information about this It’s all about the plants talk can be found here.
Predicting the response of native vegetation in Australia’s arid rangelands to management actions, such as changing grazing regimes, is often hampered by a lack of knowledge regarding the nature of native plant biodiversity at a local scale. Simply measuring above-ground plant species richness can be quite misleading because in arid habitats, much of a site’s plant diversity, particularly that of short-lived species, may be present as dormant seeds in the soil seed bank. We are investigating factors influencing variation in both above- and below-ground plant diversity in a large (ca. 420,000 km2) conservation reserve in arid South Australia. This reserve, Witchelina, has a long history (ca. 140 years) of pastoral use, but was destocked in 2010 when it was purchased by the Nature Foundation of South Australia. Particular factors being investigated include variation among different habitats and effects of past grazing intensities. For example, we are comparing the diversity and composition of the seed banks and above-ground vegetation in areas close to watering points with a history of heavy grazing with those of areas more distant from watering points that have been less heavily grazed. Alison Nicolson will also speak about her honours research on Witchelina, for which she used existing DEWNR photopoints monitoring sites at Witchelina to study regeneration since 1999. By comparing, photopoint photos taken in 2014 with field measurements, she has also been able to evaluate the reliability of using photopoints alone as a monitoring tool.
All Herbarium staff, honoraries, volunteers, students and guests welcome.
Morning tea provided.

Dee Provis, a local naturalist and community volunteer from Mundulla, in the upper South East, has kindly offered to come and tell us about the Mundulla Primary School Herbarium Project she set up. The project involved the State Herbarium’s Weeds Botanist Chris Brodie, who also attended the launch of the project. This is a great example of how different levels of government and the community can partner to achieve positive outcomes for education and the local environment.
The aims of the Herbarium Project are
…To involve students in basic plant science, using both indigenous and exotic plants from our rare Grey Box Grassy Woodland.
To teach students how to:
Identify both native plants and exotic species (weeds/garden escapees)
Collect, mount, arrange and catalogue plant samples according to the strict protocols required by the State Herbarium
Make this information available to the wider community by publications, DVD & website
To increase the body of knowledge held within the local community of both indigenous and exotic plants. This resource will support locals in identifying weeds for removal and facilitate native plant retention and regeneration.
