The State Herbarium of South Australia documents all known plant taxa (species, sub-species, varieties and forms) native and naturalised (weedy) in South Australia. These taxa are listed in the Census of South Australian Plants, Algae and Fungi. All newly discovered state and regional records are added to the Census throughout the year. The records are based on preserved plant specimens, verified by a botanists, and housed in the vaults of the State Herbarium.

For all new records of non-native plants, an annual report is produced by the Weeds Botanist Chris Brodie and colleagues from the State Herbarium. The report includes the list of new weeds recorded for South Australia with locations, descriptions, and photographs. Also documented are updates to other taxa that have had a change in distribution, weed status or name. Other activities carried out by Weeds Botanist are also summarised, such as field trips or presentations to community groups.
The latest report is now available online:
Brodie, C.J., Lang, P.J. & Waycott, M. (2019). Regional Landscape Surveillance for New Weed Threats Project, 2018-2019: Annual report on new plant naturalisations in South Australia. (4.2mb PDF).
Also available for download are last year’s 2018 report (4.5mb PDF), as well as the report for 2017 (3.8mb PDF) and a compilation of all reports from 2010 to 2016 (3.7mb PDF).

These reports highlights to land managers, which non-native plant species have recently been found in South Australia and where. New records are listed as either “naturalised/established” (*) or “questionably naturalised/established” (?e).
Naturalisedplant taxa are those that have originally been introduced by humans to an area, deliberately or accidentally. They have self-propagated without aid where they are not wanted, possibly spreading by natural means to new areas. An example listed in the recent report is Atriplex amnicola (river saltbush; 365kb PDF) from W.A. or Callitris oblonga subsp. oblonga (South Esk pine), originally from Tasmania. Both of are examples of Australian plants that have become weedy (see also a 1985 article by P.M. Kloot; 733kb PDF).
Questionably Naturalisedplant taxa (i.e. possible new weeds) are introduced non-native plants that may be self-propagating without aid, but are not well established or lack data to classify them as naturalised. An example of this are Aloiampelos ciliaris (climbing aloe) and the hybrid Eucalyptus steedmanii × Eucalyptus sp. (Steedman’s mallet hybrid).
Any unknown or possible new state or regional weed records should be reported to Chris Brodie (0437 825 685, email@example.com).

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’.
KeyBase is a database and web application for managing and deploying interactive pathway keys. It presents traditional dichotomous keys in a new way online. In addition to standalone keys, KeyBase also delivers identification keys to the new online Flora of Australia and VicFlora.
Keys to the South Australian Flora are currently being added to Keybase. Last week, Kat Ticli from the State Herbarium completed the conversion of the keys to species in Grasses of South Australia and uploaded them to KeyBase. Poaceae is one of the largest plant families in the State. Having this key and others online will enable easy access to this information and be helpful to anyone wanting to identify the native and naturalised grasses of South Australia.
