State Herbarium of South Australia

State Herbarium of South Australia. It is the primary scientific collection documenting the flora of South Australia and is a critical resource for botanical research and biodiversity conservation. The herbarium is part of the Department for Environment and Water and is located within the Adelaide Botanic Garden in the Park Lands of Adelaide. Its extensive holdings support the work of taxonomists, ecologists, and environmental consultants across Australia.

History

The origins of the herbarium trace back to the collections of early colonial botanists, including Ferdinand von Mueller and Richard Schomburgk, the first director of the Adelaide Botanic Garden. These foundational collections were formalized into a state institution in 1954, following the advocacy of botanists like John Burton Cleland. Its establishment was part of a broader movement in Australia to systematically document regional flora, paralleling developments at the National Herbarium of Victoria and the Royal Botanic Gardens, Sydney. Throughout the latter half of the 20th century, the herbarium expanded significantly through major survey projects, such as those on the Nullarbor Plain and in the Flinders Ranges, often in collaboration with the Commonwealth Scientific and Industrial Research Organisation.

Collections

The herbarium houses over one million preserved plant specimens, representing the vascular plant, bryophyte, lichen, and fungi diversity of South Australia. The collection is particularly strong in specimens from arid zones, including the Great Victoria Desert and the Lake Eyre basin, as well as marine algae from the southern coastline. It holds significant historical collections, such as those from the British Antarctic Expedition led by Robert Falcon Scott and type specimens used in seminal works like Jessie Hussey's studies on Australian lichens. The seed bank and spirit collection complement the dried specimens, supporting specialized research in plant morphology and genetics.

Research and publications

Research focuses on plant systematics, biogeography, and conservation biology, with staff regularly publishing in journals like *Telopea* and Australian Systematic Botany. A major ongoing project is the curation and digitalization of the collection through the Australasian Virtual Herbarium. The herbarium is the publisher of the comprehensive reference *Flora of South Australia* and the journal *Swainsona*, formerly the *Journal of the Adelaide Botanic Gardens*. Collaborative projects with institutions like the Australian Biological Resources Study and the South Australian Museum are common, particularly in documenting threatened species for the Environment Protection and Biodiversity Conservation Act 1999.

Governance and location

The herbarium operates under the Government of South Australia's Department for Environment and Water, with scientific guidance from an advisory board that includes representatives from the University of Adelaide and the Botanic Gardens and State Herbarium. Its physical location is the Goodman Building within the Adelaide Botanic Garden, a site managed by the Botanic Gardens and State Herbarium (South Australia). This proximity fosters close operational ties with the Australian Seed Conservation Centre and the Botanic Gardens of Adelaide.

Public engagement

Public programs include identification services for professionals and the community, workshops on topics like bushland regeneration, and contributions to citizen science platforms such as iNaturalist. The herbarium participates in major events like the Adelaide Festival of Ideas and open days at the Adelaide Botanic Garden. Its experts frequently provide evidence to parliamentary inquiries on issues like biosecurity and climate change impacts, and collaborate with Traditional Owner groups on ethnobotany projects documenting Indigenous Australian plant use.
