Back in February 2016, the State Herbarium did a blog article on Kangaroo Island couple Bev and Dean Overton. The story congratulated them for being recognised as Kangaroo Island high achievers for their outstanding efforts in conserving and raising awareness of KI’s natural environment at the Local Achievers Natural Resource Management Board Awards ceremony held on Australia Day that year.

Last year the Herbarium was approached by Kangaroo Island environmental consultant and botanist Michelle Haby to help support a nomination for Bev Overton to receive recognition in the 2019 Queen’s Birthday Honours. The final nomination was put together and submitted by Michelle and Bev’s husband Dean. Sadly Dean died unexpectedly before the news of Bev’s successful nomination was known.
You can read more of Bev’s impressive nomination here (156kb PDF). An article in THE ISLANDER newspaper also appeared recently.
Peter’s medal recognises his contribution and commitment of more than 40 years to help conserve threatened species and ecological communities in South Australia, as well as his role in biodiversity research and policy development. Peter reviewed the daisy genus Ixodia for his Honours at the University of Adelaide and has contributed 3601 collections to the State Herbarium over the years. His interest in botany was no doubt inspired by his father Bruce Copley, a Yorke Peninsula farmer who pursued an interest in his local native flora by collecting and submitting many specimens to the Herbarium.

Manager Peter Canty and Senior Botanist Peter Lang have worked closely together with Peter over many of those years, especially when they were part of the Biological Survey of South Australia program. Peter Copley lead the over decade-long biological survey of the Anangu Pitjantjatjara Yankunytjatjara Lands. The knowledge captured by that survey was greatly enhanced by working with Aboriginal Traditional Owners and Peter’s ability to establish close working relationships with the elders and their communities was pivotal in this particular survey’s success, and being recognised with a SA Great Award in 2003 in the Environment Category for an ‘Outstanding Contribution to South Australia’.

As mentioned in the article, during South Australia’s History Festival, the State Herbarium will also offer guided tours through the old Tram Barn building. Please note that the dates in the above articles are not correct. The tours will take place on Sat., 25 May & Sun., 26 May 2019.

Hon. Research Associate Pam Catcheside is among 62 authors, collaborating in this global effort to produce a phylogeny of 5,284 species of Agaricomycetes. These mushroom-forming fungi have the greatest morphological diversity and complexity of any group of fungi. They have radiated into most niches and fulfill diverse roles in the ecosystem, including wood decomposers, pathogens or mycorrhizal mutualists. This ground-breaking, first comprehensive phylogeny of mushroom-forming fungi reveals large-scale patterns of their evolutionary history.

Some years ago, State Herbarium botanist Jürgen Kellermann was contacted by Jesse Kalwij (now working in Germany) to identify an unknown shrub that was discovered about 25 years ago on sub-AntarcticMarion Island, one of the two Prince Edward Islands (South Africa). This evolved into a study examining the pathways that lead to the establishment of the plant, which turned out to be Ochetophila trinervis, a shrub in the family Rhamnaceae (see also this article). The species is native to southern South America, the closest population being over 7,500 km away. Dr Kalwij involved colleagues from South Africa, Australia, Argentina and Germany in this research, identifying the barn swallow as the most likely vector dispersing seeds of the plant to this sub-Antarctic island.

The Proceedings of the Conference with abstracts of all presentations are available for download [1.73mb PDF] from the website. Before the Conference, a workshop was held on on how to referee taxonomic manuscripts. A field trip to Springbrook and to the precipice of the remains of the Mt Warning caldera is organised for Friday.
Information on previous meetings can be found on the ASBS website. The last Conference was held in Adelaide and the 2016 meeting took place in Alice Springs. Proceedings of both meetings were published as Swainsona Supplements and can be downloaded from our journal website.
